What are “Brakes?”

Abstract

We have written article because customers often as for “new brakes” but only seem to be talking about certain parts. Basically, this article is here to help you understand more about how the system works, and therefore are better equipped to shop for parts.

This brief article is going to explain the different components of modern automotive braking system parts including pads, rotors, calipers, drums, and more. We have written article because customers often as for “new brakes” but only seem to be talking about certain parts. Basically, this article is here to help you understand more about how the system works, and therefore are better equipped to shop for parts.

Brakes aren’t the round metal discs behind the wheel. Nor are brakes the parts that wear out and squeak.

“Brakes” refer to a set of components that work together to bring a vehicle to a stop once it is moving. Braking systems on most modern vehicles are hydraulically actuated. The brake pedal acts on a master hydraulic cylinder which, usually with the assistance of a vacuum-powered booster, pressurizes a hydraulic line and actuates cylinders at each wheel. A proportioning valve controls the bias of pressure to all four corners.

The cylinders at each wheel actuate either pistons in a caliper (for disc-brake applications) or a wheel-cylinder (on drum brakes). In disc brakes, the caliper pistons push on brake pads that have friction linings. These linings are forced against brake discs, or rotors, which turn with the vehicle’s wheel hub. This force slows the turning of the wheel and slows the vehicle.

Drum brakes work similarly with different components. Wheel cylinders push brake shoe-linings against the insides of a drum that spins with the wheel hub to slow the vehicle. Drums on modern cars are used in rear applications, if at all, and are mainly used for cost savings in low-demand applications since disc brakes are much more efficient at stopping vehicles.
