ELECTRONIC CONTROL UNIT(ECU): Describes the "brain" of an ABS. that reads impulses generated from the wheel speed sensors to determine if anti-lock braking needs to occur.
EMERGENCY BRAKE: Describes a braking system that is independent of the central hydraulic system. It can slow or stop the vehicle if the primary brakes fail or hold the vehicle stationary though the brake pedal is not depressed. Also known as the "parking brake" or E-brake.
EXPANDER: Describes a device that can be installed in a drum brake system (either hydraulic or mechanical) that will part the brake shoes, forcing them into contacting the drum
FIXED-CALLIPER DISC BRAKE: Describes a disc brake with a fixed calliper consisting of two halves bolted together and containing at least one cylinder and piston.
FIXED-CAM BRAKE: Describes a drum brake where the cam is rigidly mounted to the backplate.
FLOATING CAM: Describes a brake cam that is not rigidly mounted in the brake backplate of a drum brake, making it capable of exerting equal pressure on the two shoes.
FLEXIBLE BRAKE PIPE: Describes a pipe connecting the wheel cylinder to the rest of the system that flexes o allow for the up and down movement of the wheel
FLOATING CALLIPER DISC BRAKE: Describes a disc brake with a single piston, in which the calliper itself can move to bring both pads into contact with the disc.
FOOT BRAKE: Describes the primary braking system operated by a foot pedal
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (ABS): Describes an anti-lock brake system that runs on all four wheels
FOUR-WHEEL DISC BRAKES: Describes a vehicle with disc brakes fitted to both front and rear wheels
FRICTION LINING: Describes the wear-resistant friction material used for brake linings.
GLAZE LINING: Describes a brake lining that has overheated, becoming smooth and glossy and largely ineffective.
HANDBRAKE: Describes a brake operated by a hand lever. Also referred to as a parking brake.
HARD SPOTS: Describes the shiny bluish/brown glazed areas sometimes found on a brake drum or similar surfaces, caused by extreme heat, usually removed by resurfacing.
HAT: Describes the part of a detachable brake disc.
HEEL: Describes the end of the brake shoe that rests against the anchor pin.
HOLD-DOWN PIN, SPRING AND RETAINER: Describes the most common method of attaching a brake shoe to the backing plate.
HUBCAP: Describes the covering designed to fit over the end of the wheel spindle to keep dust and water away from the wheel bearings and brakes.
INNER ATTACHMENT FACE: Describes the part of the brake disc directly fixed to the wheel hub.
LINING: Describes a friction material found on brake shoes and brake discs.
