Basic Components of Braking Systems
Disc Brakes- this system uses a metal disc that is pinched by special brake pads to slow the vehicle. They offer superior braking and are usually on the front wheels which do 70% of the braking. They are optional for all four wheels.
Drum Brakes- in this enclosed system, wheels are stopped by brake shoes that push out on a drum.
Dual Master Cylinder- the master cylinders work independently to pressurize the brake fluid. The pressurized fluid activates the brake mechanism. Redundant independents systems allow you to brake even if one fails.
Brake Lines- steel tubes that carry brake fluid and conduct hydraulic pressure.
Power Brake- reduces the driver’s effort to brake by enlisting the engine to boost brake pressure. The power brake system is designed in such a way that should the engine fail, braking will still work one more time.
Parking Brake- also called the emergency brake, it uses cables and levers to activate the rear brakes in case the hydraulic brakes fail. It should also be engaged when parking on a hill or slope.
