Master Cylinder
A vacuum, electric, or power steering-operated device that assists brake pedal application
What is the brake booster?
Equalizes braking action on each wheel when braking
What is the metering valve?
Department of Transportation
What does DOT stand for?
Providing a rubbing surface for the brake shoe linings
What are brake drums?
Hose that transfers fluid pressure from the master cylinder to the wheel brake assemblies
What are brake hoses?
Hydraulic-piston pump that develops pressure for the hydraulic brake system
What is the master cylinder?
Valve used to equalize braking action on vehicles with front discs and rear drum brakes
What is the proportioning valve?
Provides a mechanical means of applying brakes
What is the parking brake?
Term for the front that normally has a slightly shorter lining than the secondary shoe
What is the primary brake shoe?
Uses friction from the brake pads to slow or stop wheel rotation
What is a rotor?
Emergency brakes are mechanical or electric systems for applying rear assemblies
What is the parking brake?
Functions as a brake light warning, metering valve, and for proportioning valve
What is the combination valve?
Metal tubing and rubber hose for transmitting pressure to wheel brake assemblies
What are the brake lines?
Term for the rear brake shoe that has the largest lining surface area
What are secondary brake shoes?
Friction members that are pushed against the disc by the action of the master cylinder, caliper cylinder, and piston
What are brake pads?
Releases extra pressure when the piston returns to the released position
What is the compensating port?
Pressure-sensitive switch that warns a driver of a pressure loss on one side of hydraulic brake system
What is the brake warning light switch?
A foot lever for operating the master cylinder and power booster
What is the brake pedal assembly?
What are brake shoes?
Clip that snaps on to a brake pad to keep it from vibrating and rattling
Uses fluid pressure, instead of vacuum, to help force the piston foward
What is the hydro booster?
Spring loaded electrical switch that operates rear brake lights when the brakes are actuated
A specially blended hydraulic fluid that transfers pressure to the wheel brake assemblies
What is brake fluid?
Acts as the power piston, moving the friction linings into contact with the rotating drums or discs
What are wheel cylinders?
A brake assembly part that holds a hydraulic cylinder, piston seals, and brake pads
What are calipers?
