Disc brakes are normally fitted on Front brakes Disc brakes can be further classified as : Fixed Caliper - Where there are separate wheel cylinders each for inner & outer brake pad. (used in earth moving equipment) Floating Caliper - Where there is only inner pad is moved by the wheel cylinder , the outer pad is moved by the caliper. Floating caliper brakes can be further classified as : Single pot - Where one wheel cylinder operates the inner pad Twin pot - Where two wheel cylinders operates the inner pad BRAKES DISC BRAKES - FLOATING CALIPER - SINGLE POT BRAKE CALIPER (MOVING) BRAKE FLUID FROM MASTER CYLINDER BRAKE PADS WHEEL CYLINDER BRAKE DISC BRAKES DISC BRAKES - FLOATING CALIPER - TWIN POT BRAKE CALIPER (MOVING) BRAKE FLUID FROM MASTER CYLINDER BRAKE PADS WHEEL CYLINDERS BRAKE DISC BRAKES DISC BRAKES - FIXED CALIPER BRAKE CALIPER (FIXED) BRAKE FLUID FROM MASTER CYLINDER BRAKE FLUID FROM MASTER CYLINDER BRAKE PADS WHEEL CYLINDER BRAKE DISC BRAKES 3. BRAKE BOOSTER - Also known as Brake Servo. Brake booster is fitted between the brake pedal and the tandem master cylinder. Brake booster supplies additional effort to the tandem master cylinder as soon as the brake pedal is pressed by the driver. The additional effort is derived from the vacuum generated by the vacuum pump. Brake pedal efforts are lower when equipped with brake booster. Brake boosters are specified by the diameter of the diaphragm - 9” or 10” In case of failure of the brake booster or loss of vacuum, the braking system reverts to manual system. More effort will be required to stop the vehicle. TANDEM BOOSTER - Tandem boosters are 2 boosters of different sizes sandwiched in to one housing.

PRESSURE CONTROL VALVES - Pressure control valves modify the brake fluid pressure to the rear braking circuit, under certain conditions to avoid rear wheel locking. When a vehicle is braked at high speeds, weight transfer happens. The vehicle weight shifts to the front axle. There will be rela...
