Brakes Unit 1

A screw that allows air to be removed from a hydraulic brake system. When the screw is loosened, hydraulic pressure can be used to force fluid and air out of the system.

• torque screw

• bleeder screw

• set screw

• machine screw

A specially blended hydraulic fluid used to transfer power and motion from the brake pedal to the wheel cylinders and brakes.

• power steering fluid

• 5w 30 motor oil

• brake fluid

• transmission fluid

A hose that transfers fluid pressure from the master cylinder to the wheel brake assemblies.

• brake hose

• vacuum hose

• fuel line

• power steering hose

A metal tubing and rubber hose for transmitting pressure to wheel brake assemblies.

• pressure line

• vacuum line

• brake line

• a/c line

A brake assembly part that holds a hydraulic cylinder, piston, seals, and brake pads.

• wheel cylinder

• master cylinder

• knuckle

• caliper

A caliper that can move back and forth in relation to the rotor.

• fixed caliper

• floating caliper

A single unit that functions as a brake warning light switch, metering valve, and/or a proportioning valve in the brake system.

• primary valve

• combination valve

• secondary valve

• actuator valve

A corner-to-corner brake system that has each master cylinder piston operating the brake assemblies on opposite corners of the vehicle.

• front to rear split brake system

• diagonally split brake system

• side to side split brake system

• abs brake system

A master cylinder that has two separate hydraulic pistons and two fluid reservoirs. Also referred to as a tandem master cylinder.

• dual master cylinder

• cast iron master cylinder
