<SECONDARY BRAKING SYSTEM: Describes a spring-loaded brake system that exerts force when air pressure is released.
SELF-ENERGISING BRAKE SHOE: Describes a form of brake shoe that develops a wedging action boosting the braking force applied by the wheel cylinder when the brakes are pressed.
SERVICE BRAKE: Describes a foot-operated brake used for retarding, stopping, and controlling a vehicle during normal driving conditions.
SERVO ACTION BRAKES: Describes a braking system designed and constructed to have one end of the primary shoe bearing against the end of the secondary shoe, allowing for brake pressure to be more gradual.
SILICONE BRAKE FLUID: Describes a form of brake fluid that does not absorb water.
SINGLE-ANCHOR SELF-ENERGIZING BRAKE: Describes a variation of the servo brake system in which both shoes pivot about one fixed point.
SINGLE-CIRCUIT BRAKING SYSTEM: Describes an older form of hydraulic braking system with a single circuit that serves all four brakes.
SINTERED METAL BRAKE PAD: Describes a brake pad produced from Sinter designed to reduce noise and increase the brake pad's performance and life.
SLIDING-CALLIPER DISC BRAKE: Describes a design of disc brake characterised by its sliding calliper.
SOLID BRAKE DISC: Describes a form of brake disc that has solid metal between its friction surfaces.
SPLASH SHIELD: Describes a device, sometimes removable, fitted on disc brakes to keep foreign bodies from fouling the brakes.
STATIC PRESSURE: Describes the level of pressure maintained by a check valve that permanently remains in a vehicle's brake lines even when the brake pedal has been released.
VACUUM BRAKE BOOSTER: Describes a type of device directly connected to the master cylinder, mounted on the engine side of the bulkhead that uses engine manifold vacuum to generate additional braking force.
VACUUM TANK: Describes a type of tank used to provide vacuum to a power brake installation in the event engine vacuum cannot be obtained.
VENTILATED BRAKES: Describes a type of brake setup that allows air to enter to cool the rotor and calliper.
VENTILATED DISCS: Describes the two discs in a disc brake system separated by ribs and channels to allow cooling air to disperse the heat between them.
YOKE: Describes a triangular-shaped metal piece used to connect the main brake cable with the stirrup cable in a centre pull brake system.
