Typical Braking System Components
The front braking system comprises of a Brake Disc, Brake Caliper and a set of Brake Pads.
On a disc brake the fluid from the master cylinder is forced into a caliper where it pushes against a piston. The piston then squeezes two brake pads against the brake disc which is attached to the wheel, forcing the vehicle to slow down or stop. There are two brake pads attached to each disc
brake. The heat that is generated from this friction is what causes brake pads and discs to wear out.
The rear braking system has either the same as above or a drum brake system. The difference
between the two is that instead of Brake Pads and Calipers a drum brake system has Brake
Shoes and Wheel Cylinders. On this type of system the fluid from the master cylinder is
pushed into the Wheel Cylinder which expands a piston on either end and pushes the Brake
Shoes out making contact with the Brake Drum that the shoes are encased in. Although this
system has proved very reliable, on a vast majority of new cars, this type of system is being
replaced by the conventional Disc Brake system as a majority of new cars are being equipped
as standard with Anti-Lock Brakes (ABS).
The Brake Master Cylinder is the heart of the braking system. It has a reservoir that sits on top of
the unit which feeds the hydraulic fluid throughout the braking system. It comprises of a piston
which, when the pedal is pressed, pushes a piston forward and applies pressure throughout
the brakes hydraulic components at each wheel. Master Cylinders are very reliable and rarely
fail, however like any other highly stressed component this is not always the case.
