Glossary “brake drum glaze” Definition:
A brake drum with an excessively smooth surface that lowers friction and, therefore, efficiency.

Glossary “brake equalizer” Definition:
A device used in the parking-brake systems to equalize the pull of both rear-brake cables during parking brake application..

Glossary “brake fade” Definition:
Condition whereby repeated severe application of the brakes, over a short time period, cause an expansion of the brake drum and/or loss of frictional ability, which results in impaired braking efficiency. When every brake shoe are wet, they lose braking ability. Off gassing from the pads can also cause this condition. If the brake fluid is overheated and becomes vaporized, this condition will also occur.

Glossary “brake disc” Definition:
The parallel-faced, circular, rotational member of a brake, acted upon by the friction material of the pads.

Glossary “brake disc minimum thickness” Definition:
Term used to indicate disc minimum thickness.

Glossary “brake dive” Definition:
Term used for dive in the front end when the brakes are applied and a high rate of deceleration is occurring.

Glossary “brake bleeding” Definition:
Procedure for removing air from lines of a hydraulic brake system.

Glossary “brake booster” Definition:
A device that uses a supplementary power source to reduce pedal force in a hydraulic brake system.

Glossary “brake caliper” Definition:
The part of a disk brake system that converts hydraulic pressure into mechanical force that applies the pads to the rotor. The caliper is mounted on the suspension or axle housing and contains a hydraulic piston and the brake pads.

Glossary “brake chamber” Definition:
A unit in which a diaphragm converts pressure to mechanical force for actuation of a brake.

Glossary “brake control valve” Definition:
A unit that sends a signal to the computer when the brakes are being applied.

Glossary “brake cylinder” Definition:
That part in which a piston converts pressure to mechanical force for actuation of the brake shoes.

Glossary “brake anchor” Definition:
Pivot pin that is mounted on the brake backing plate, against which the brake shoe(s) are held, as to not rotate in the direction of the drum when the brakes are applied.

Glossary “brake assembly” Definition:
An assembly of the components of a brake system, including its mechanism for the application of friction forces.

Glossary “brake band” Definition:
A round, flat metal band with a friction surface on its inner diameter; used primarily in parking brake systems, but can also refer to the band used in A/T.

Glossary “brake bias” Definition:
An excessive brake force at either end of the vehicle causing the brakes at that tend to lock before the other end, often leading to loss of control.

Glossary “brake bleeder” Definition:
Hollow threaded components that allows the system to be opened for the purpose of bleeding or flushing the system. Located at the wheel cylinders, calipers, or accumulator. Also refers to a piece of equipment that supplies brake fluid under pressure that is used to bleed or flush the brake system.
