Borgman How To: Understanding Your Vehicle's Braking System

The Borgman Service Center - Your Home For Expert Brake Service in West Michigan

Brakes do an awful lot of work, even on a simple trip around Grand Rapids or to the grocery store. Bringing a moving vehicle to a complete stop is no small feat, even though we may take it for granted. On the other end of that brake pedal are some clever feats of engineering that harness the power of hydraulics and friction to turn a vehicle's kinetic energy into heat.

The Borgman Service Center in Grand Rapids is your home for making sure your brakes and other systems within your vehicle are properly functioning and maintained. In our latest Borgman How To, we'll give you a general idea of how this system works and enough insight to know when it's losing performance. Here's the "Brake-Down" of major components:

  • Hydraulic Components: The two main components connected to the brake pedal are the Master and Slave Cylinders, which compress fluid to multiply the force from the brake pedal. The fluid is distributed to the vehicle's wheels to power the brakes.
  • Disc Brake Components: Disc brakes are very common on the front wheels because of their efficiency. They consist of a rotor, calipers, and pads with an open design to quickly dissipate heat.
  • Drum Brake Components: Drum brakes are very common on the rear wheels because of their durability. They consist of a metal drum that spins with the wheel, and shoes that press against the insides. They require much less maintenance and are often used for the emergency brake.

Hydraulic Braking System Basic Components

Hydraulics are based Pascal's Principle: "Pressure exerted on a fluid is distributed equally throughout the fluid." This is possible because fluids don't compress the same way gasses do, enabling you to press down gently on a brake pedal and have that small amount of pressure affect all of the fluid in the system. It is then multiplied and used to stop the entire vehicle. The system you'd find in a New Ford or Mazda is more complex than this example, but here's a rundown of the basics:

When you use the brake pedal, it pushes on a plunger in the master cylinder, building pressure. Brake fluid is forced through the plumbing to the 4 wheels of the vehicle, where slave cylinders further amplify the hydraulic force. This fluid then actuates pistons in the brakes with enough force to create enough friction to stop the wheel. Modern systems also use enhancements like a "brake booster" which uses vacuum to assist with compressing the master cylinder. This whole hydraulic system is responsible for stopping the vehicle and therefore your safety and those around you, so it is common to see redundancies like two master cylinders. If you notice your brake pedal feeling spongy or needing more pressure than usual, check your brake fluid level and schedule an appointment.

Note on Brake Fluid: If you do your own fluid checks, and we highly recommend that you do, you might notice low brake fluid. A little fluid loss is normal as the pistons in the calipers extend with wear (the system is actually just getting bigger) but a dramatic loss usually points to a leak. While hydraulic theory applies to most liquids, brake fluid is specially-formulated for vehicles. It is hygroscopic, meaning it absorbs moisture, and this is to make sure the boiling point stays high (fluids boil under pressure) and that water cannot pool in the brake system. If you open a bottle of brake fluid and don't use all of it, seal it up tightly and write the date on the bottle. It's already started absorbing water from the air, so you'll want to use it in 3 to 6 months or throw it away.

The Difference Between Disc & Drum Brakes

Disc brakes, the ones you'll interact with most, are often found on the front wheels because they're more heat-efficient and easier to service. Here, pressurized fluid from the slave cylinder squeezes down on the rotor through the caliper pistons. The rotor is attached to the wheel and spins, but the caliper is mounted to the vehicle itself.

Brake pads are fixed to the inside of the caliper and are made of high-strength and heat-resistant materials like ceramic or carbon. As they squeeze down to the spinning rotor, they generate enough friction to slow the vehicle. On the front wheels, brakes have to work harder and can reach temperatures of over 900°F. Disc brakes work best here because they cool much faster than drums - thanks to their open construction. The pads wear faster, but they're much easier to replace.

Drum brakes are built differently. Instead of a rotor, a metal drum houses a series of shoes that push against the rotating edges from the inside. Their construction is more durable, but they tend to trap heat so they're often only used on the rear wheels. If the shoes (different type of pads) are heated well above 900°F, they lose their "grippiness" - colloquially called heat fade - and the vehicle may not be able to stop.

Thankfully, the rear brakes are doing much less work than the front, and this is by design. As the weight of the vehicle shifts forward while stopping, too much braking force in the back can lock up the rear wheels and cause them to skid. The master cylinder sends less force to the back to counter this, making the rear brakes more supplemental than active. However, the emergency brake is usually connected to the back wheels, so it's important to have them inspected - even if they don't need service as often.

2026 Towing Guide: Pro Tips For a Successful Summer Trip

The summer towing season is finally here! At Borgman, we know the West Michigan summer is best enjoyed with a boat, camper, ATV, dirt bikes, or whatever else you want to bring with you to your favorite getaway. While getting out of town and enjoying the warmer weather is great, making sure you tow your trailer safely is important, too. Take a look at our revised towing guide for a quick tutorial (or refresher) on what to do, what not to do, and then head to the Borgman Service Center for a pre-vacation checkup or to have new towing equipment installed! more 2026 Towing Guide for West Michigan Adventurers Before Hitting The Road: If you're reading this in preparation for towing for the first time, it's worth visiting Borgman to ensure your vehicle is properly equipped. We will make recommendations about which parts will be necessary to tow your trailer or camper safely, then order the parts for you and install them as soon as possible. That way, your vehicle spends less time in the shop and more time out on the road, and you're towing with confidence. To see what parts are available for your vehicle and the current pricing, visit Accessories.Ford.com. Finally, even if your vehicle is properly equipped and you're a towing veteran, getting a quick checkup before setting out is critical for everyone's safety and prolonging the life of your vehicle. Take a look at our Service Specials and Schedule An Appointment today. Weight Distribution For the best braking and handling performance, your vehicle's load must be properly distributed - keeping the center of gravity as low as possible. Approximately 60% of the allowable cargo weight should be in the front half of the trailer, and the rest in the rear (consult limits of tongue load or king pin weight!) The load should be balanced from side to side, too, and must be firmly secured to prevent shifting during cornering or braking. Backing Up With A Trailer If you've never done this before, you might want to get some practice in before needing to do it "out in the wild." All you need to do is back up slowly, and have someone help you by standing behind the trailer guiding you in. Put one hand at bottom of the steering wheel and move it in the direction you want the trailer to go. Make small steering movements - the trailer will move more than you'd expect. Remember, you can always go forward to readjust or start over. Backing up a trailer can be tricky! Braking Remember, your vehicle is going to be heavier so it'll take longer to stop. Some Ford Vehicles equipped for towing will include electronic braking assistance for your vehicle and your trailer if it has brakes, but it's still good practice to drive more defensively. Allow more space between you and the vehicle in front of you to give yourself time to stop safely. If your trailer starts swaying, the easiest way to correct it is to gently speed up. If that's not helping and your vehicle is equipped with electric brakes and a brake controller, activate the trailer brakes with the brake controller by hand. Do not apply the tow vehicle's brakes as this can make things worse. Towing On Hills Downshift the transmission to assist braking when going down steep hills and to increase power (reduce lugging) when climbing hills. With the Ford TorqShift® transmission, simply select tow/haul mode to automatically eliminate unwanted gear search when going uphill and help control your vehicle speed when going downhill. Parking With A Trailer Whenever possible, vehicles with trailers should not be parked on a hill - even on a slight incline. If it can't be avoided, you can place wheel chocks under the trailer's wheels, following the instructions below: Apply the foot service brakes and hold Have another person place the wheel chocks under the trailer wheels on the downgrade side Once the chocks are in place, release the brake pedal, making sure the chocks will hold the vehicle and trailer Apply the parking brake Shift the automatic transmission into park or the manual transmission into reverse With 4-wheel drive, make sure the transfer case is not in neutral (if applicable) Acceleration And Passing The added weight of the trailer can dramatically decrease the acceleration of the towing vehicle - exercise caution. When passing a slower vehicle, be sure to allow extra distance. Remember, the added length of the trailer must clear the other vehicle before you can pull back in. Signal and make your pass on level terrain with plenty of clearance. If necessary, downshift for improved acceleration.

The Reduced Maintenance Needs of Your Ford Electric Vehicle

Getting behind the wheel of your first Ford Electric Vehicle is an exciting experience, especially with the warmer weather on the way. Among all of the perks of owning an EV, which include no tailpipe emissions, charging at home, and much more cargo space, one of the biggest people don't often consider is reduced maintenance costs. Electric Vehicles have far fewer moving parts when compared to their internal-combustion counterparts, and will never need things like oil changes, oil filter changes, fuel filters, spark plugs, radiator flushes, and more. However, there are still some features of your EV you should not neglect, and since service visits for oil changes are primarily where our techs spot other problems, it's paramount that owners bring their vehicles in for inspections on schedule. Here are some of the most important features of TVs that you should include in your maintenance regimen. Rotating and Replacing Tires This is perhaps the most obvious item on the list, but it's important to mention all the same. As your sole contact with the road, your tires need to be properly maintained to ensure your safety and maximize their lifespan. We recommend rotating your tires every other oil change at a minimum, but in this case, every 5,000 to 10,000 miles would be ok. Rotating your tires on a regular basis not only extends their lifespan but also allows our technicians to check for other subtle issues, such as uneven tread wear caused by poor alignment or worn suspension parts. It also gives us an unobstructed view of your brakes, basically amounting to a free inspection of your front end. Brake Pads, Rotors, Calipers, and Braking System Parts Brake maintenance is also very important for your safety and the safety of other drivers. Brakes use hydraulics to squeeze the calipers against the spinning rotor, which is locked to the wheel, slowing it down. Pads (or in rare cases, shoes,) help the caliper grip the rotor, so it's very important that all four of these pieces are inspected regularly. Many EVs are also equipped with regenerative braking, which uses the energy from slowing the vehicle down and feeds it back into the battery, leading to longer battery range and miraculously, longer brake life. While we urge owners to have their brakes inspected regularly, they will not need to be replaced or serviced nearly as often. Battery and Electric Motor Maintenance This will be a short section, as your electric vehicle batteries and motors will require little to no maintenance over the life of the vehicle. These components will last roughly the same amount of time as an internal combustion engine, though many experts predict they will last much longer. The best way to ensure this is to carefully follow the charging instructions in your owner's manual. Electric Vehicle Transmission The transmissions in electric vehicles do not have the same transmission as most gas-powered vehicles, though more and more are being equipped with something similar. A continually-variable transaxle, or CVT is a type of transmission that uses belts instead of traditional gears to transmit power from the engine to the wheels. Since the electric motors on EVs are more closely tied to the wheels, a different setup is required, but the principle is the same. These transmissions will need some maintenance over their lifetime, but not much. Be sure to carefully follow your recommended maintenance schedule, as the EV motors and transmissions are among the more expensive components of your electric vehicle. Shocks, Struts, and Suspension Components Just like gas-powered vehicles, electric vehicles will still need routine maintenance performed on suspension components, such as shocks, struts, and occasionally things like control arms, tie rods, and more. Regular tire rotations can usually catch these issues before they fully develop into expensive problems. Be sure to stay up-to-date on your alignments and inspections and you'll see costs on par with what you'd expect with a non-electric vehicle. Trust the Borgman Service Center For Your Electric Vehicle Needs Your electric vehicle has different maintenance needs than the vehicles we've grown accustomed to. However, some of the needs are the same. EVs will still require tires, headlights, taillights, turn signals, windshield wipers, and more.

When Was The Last Time You Replaced Your Vehicle's Air Filters?

When was the last time you replaced your cabin air filter? In the spring, you’re likely inhaling more allergens, irritants, and pollutants. Your vehicle breathes too, and clogged filters mean it’s working harder than it needs to. Cabin Air Filters should be changed at least every 30,000 miles, but if you frequently drive in areas with a lot of pollution, you should change it sooner. The same goes for your engine air filter. If you have all of your regular maintenance done at Borgman, we keep track of these things and let you know when it's time. If you're just a tiny bit handy, both of these parts are easy enough to find and check. Cabin Air Filters are usually located behind your glove box, and the Engine Air Filter is right on top when you open the hood. Your manual will tell you exactly where they are, and what size you need. When you pull them out, most of the time it'll be pretty apparent if they need to be changed. However, if you're short on time or need help, Borgman is here to make sure you breathe easy this summer. What The Cabin Air Filter Does Your cabin air filter does exactly that - filters the air coming into your vehicle from outside. They're made of pleated material designed to trap incoming pollutants like dust, pollen, spores, and other particulates in the air and prevent them from entering the cabin when the heat or AC is on. When your filter starts to get clogged up with these pollutants, you might notice first that your vents don't blow as strong as they used to. Next, you might notice a musty smell, and then finally a whistling noise, as air is forced to find its way through gaps. Simply changing the filter will correct all of these issues at the source, but it may take some extra cleaning to get the musty smell out. If you're having trouble finding or replacing your cabin air filter, talk to the experts at Borgman - we'll have it replaced for you in no time. What The Engine Air Filter Does Just like how the Cabin Air Filter keeps airborne gunk out of your interior, the Engine Air Filter keeps the same things from getting inside your engine. These usually look like a bigger version of a Cabin Air Filter and are most commonly a cartridge style. However, some older or custom vehicles will have a drum style. Your engine needs three things to turn the wheels: fuel, spark, and fresh air. Just as your fuel filter removes any fine particulate, your air filter removes dirt, pollen, and other contaminants so they don't mix with fuel and coat your engine parts with carbon. If you don't have this filter changed, you'll notice your engine feeling sluggish and using more fuel to get moving. It makes sense when you think about it - try running a mile while holding your breath. Eventually, air will find its way in, carrying things the filter is supposed to be keeping out, and that means really expensive repairs. Borgman Service Center in Grand Rapids Helps You And Your Vehicle Breathe Easier If you're wondering when the last time your air filters were changed, give us a call at the Borgman Service Center. If you have us do all of your maintenance, we can check your file and let you know if you're overdue or not. If this is your first time with us, we'll take a look at both and make an honest recommendation. However, if you're in doubt, these are fairly inexpensive parts to replace. To get started, use our easy Online Scheduler to make your appointment, then check out our Service Specials for the latest discounts. We've been keeping West Michigan moving since 1960, and it'd be our pleasure to serve you. Come see why we're the Best in the West!
