Brakes

The brake system is actually composed of two kinds of systems---Hydraulics and Friction Materials. Here's what happens within these systems between the time your foot hits the brake pedal and your car stops.

Hydraulics

Master Cylinder

When pressure is applied to the brake pedal, the master cylinder creates hydraulic pressure which pushes brake fluid to the wheel brakes.

Brake Lines and Hoses

Steel brake lines and high pressure rubber hoses are the avenues through which the pressurized brake fluid travels.

Wheel Cylinders & Calipers

These are the hydraulic cylinders that apply pressure to the friction materials, causing your car to stop.

Friction Materials

Disc Brake Pads and Drum Brake Shoes

These brake linings are composed of high temperature materials that create the friction that stops your car.

Types of Brakes

Disc Brakes

Disc brakes consist of a Disc Brake Rotor, which is attached to the wheel, and a Caliper, which holds the Disc Brake Pads. Hydraulic pressure from the Master Cylinder causes the Caliper Piston to clamp the Disc Brake Rotor between the Disc Brake Pads. This creates friction between the pads and rotor, causing your car to slow down or stop.

Brake System

Drum Brakes

Drum brakes consist of a Brake Drum attached to the wheel, a Wheel Cylinder, Brake Shoes and Brake Return Springs. Hydraulic pressure from the Master Cylinder causes the Wheel Cylinder to press the Brake Shoes against the Brake Drum. This creates friction between the shoes and drum to slow or stop your car. (See more about Drum Brakes, below)

 

Parking Brake

The Parking Brake uses Cables to mechanically apply the brakes (usually the rear brake.) This is used to prevent the car from rolling when not being driven.

Anti-Lock Brakes: A System Built For Safety

Computer-controlled anti-lock braking systems (ABS) are a recently developed safety feature. When sudden stops are made, the ABS prevents wheel lock-up. The system is comprised of wheel-speed sensors that monitor wheel rotation, computer-controlled hydraulics that pulse the brakes on and off rapidly, and the on-board computer.

Did You Know About

Hydraulic brake fluid replacement is not listed in some owner's manual service schedules. Ask your service advisor about when he would recommend a power brake fluid replacement. Fresh fluid has adequate levels of anti-corrosion additives that can help protect expensive brake components.

Drum Brakes

Brakes that work properly are essential to your safety as you drive and stop on Bellevue and Eastern Nebraska streets. You want to carefully maintain your brakes. In vehicles equipped with drum brakes, the brake components are housed inside a drum that rotates with the wheel. When you step on the brake pedal, brake shoes push out against the inside of the drum, slowing the wheel.

Now brake shoes just wear away with use from rubbing on the drum as you brake. When it's time to replace brake shoes, it's a straight-forward repair.

If you hear squealing or grinding when braking, have your Bellevue service advisor check them out. He'll have a technician perform a thorough brake inspection to see what needs to be done. He'll check for signs of brake problems and go over other brake components to see that they're working properly.

He can tell you if it's time to replace the brake shoes or if there are other issues with your brakes that should be addressed. Some people in our Bellevue community ignore the warning signs and keep driving long after the shoes are completely worn out. When that happens, metal brake components will grind against the drum, damaging it enough that it has to be resurfaced or replaced.

When you push on your brake pedal, the wheel cylinder is activated and it pushes the shoes against the drum to slow the vehicle. This cylinder, and various springs within the brake, can wear out affecting your ability to stop . The worn components can be easily replaced.

The new brake shoes we put on your truck or other vehicle will restore your brakes to manufacturers' specifications. Or, we can install upgraded parts to increase your stopping power and reduce brake noise and brake dust . We have several options to meet your braking requirements and your budget.

Taking care of your brakes keeps them working safely and you could prevent premature brake repairs down the road.
