Brake Repair and Service

Dependable Brake Repair and Service at Yocum Automotive, Republic, MO

Your vehicle’s braking system is the most important system on your vehicle – yes, even more so than the engine. Even if the engine is running, driving without functional brakes is not only dangerous—it’s irresponsible. Yocum Automotive’s certified auto technicians in Republic, MO can provide top-notch brake repair and service, whether you have disc brakes or drum brakes.

Components in the Brake System

Every vehicle’s braking system consists of a brake on each wheel plus an emergency brake. Vehicles manufactured from 2012 and later must have the antilock braking system (ABS). While the United States didn’t mandate it until 2012, it was in use for decades by then.

Brake Pads

As part of the disc brake system, brake pads clamp the rotors to slow the vehicle when you step on the brake. You should have your mechanic check the brake pads every time you bring your vehicle in for maintenance. If you ignore worn brake pads, you lose stopping power and can cause damage to the rotors and calipers.

Brake Rotors

Also part of the disc brake system, rotors are large, round metal discs. The brake pads rub on them to create friction to slow the vehicle. Rotors will wear out over time. Most people can get away with changing the brake pads at least once before having to change the rotors. In some cases, your brake tech can “turn” the rotors to smooth them out. Usually, they can only do that once before they become too thin.

Brake Calipers

The calipers use brake fluid forced through the system to press the brake pads against the rotors. They last much longer than pads and rotors but can eventually develop leaks. If you ignore bad brake pads, the calipers could become over-extended.

Wheel Cylinders

Some trucks and older cars still use drum brakes. Each wheel with drum brakes has a wheel cylinder that presses the shoes against the drum. They often develop leaks and have to be changed almost as frequently as the shoes.


The drums are large round metal “dishes” that fit over the shoes on the wheel. When you step on the brakes, the wheel cylinders press the shoes against the drums to slow the vehicle.


Brake shoes are made of long, curved pieces of braking material attached to a metal backing plate. The shoes rub against the drums when you apply the brakes to cause friction to slow the vehicle.

Brake Booster

The braking system uses vacuum and hydraulics to work the brakes. While the engine generates a vacuum, it’s not enough. The large round canister on the driver’s side firewall in the engine compartment is a vacuum booster, which creates the additional vacuum power brakes required to work properly.

Master Cylinder

The master cylinder holds the brake fluid. If it leaks or the seals break, it won’t have enough pressure to push the brake fluid through the lines to push the calipers or wheel cylinders. When you change the master cylinder, you must also bleed the brakes – the system cannot have any air in it, or the brakes will not work properly.

Anti-Lock Braking System (ABS)

The ABS uses a computer to control the brakes electronically. If a brake locks up when you have to stop quickly, the computer loosens the brake pads on the locked-up wheel and then reapplies the pressure. This keeps the wheel from locking up and causing the vehicle to spin out. If the ABS computer goes bad, you can still drive, but it is like driving with old-fashioned brakes. It’s easier to spin out, especially on wet or snowy roads.
