Unformatted text preview: tively very less weight in the rear axles. The brake fluid pressure is same for both front & rear axles. This will lead to “Rear Wheel Lock” condition. A locked rear wheel will lead to vehicle instability and skidding/Tail swing. Pressure control valves reduce the brake fluid pressure to the rear circuit , under these conditions. Pressure control valves are classified as : PCRV - Pressure Conscious Regulating Valve DCRV - Deceleration Conscious Regulating Valve - Bolero (G-valve) LCRV - Load Conscious Regulating Valve - Scorpio (LSPV) BRAKES G-VALVE - G-valve is a deceleration conscious pressure regulating valve, fitted on the rear brake circuit. When the vehicle is braked hard, the g-level of the deceleration is sensed by a steel ball , which rolls forward and partially blocks the brake fluid to the rear brakes. TYRE TYRE BRAKE BRAKE BRAKE BRAKE TYRE TYRE G-VALVE G-Valves are fitted at a specified angle in direction of vehicle motion BRAKES LCRV (Load Conscious Regulating Valve) - Also known as LSPV (Load Sensitive Pressure Valve). LCRV detects the load on the vehicle and accordingly regulates the brake fluid pressure to the rear brakes. Load (fully laden or unladen) is detected by height difference between the rear axle and the body , using levers or springs. BODY LCRV/LSPV BODY SPRING UNLADEN LADEN BRAKES 5. VACUUM PUMP - Vacuum pump generates vacuum for the brake booster. Vacuum pumps are mounted on the rear side of the alternator and are generally driven by the engine by a belt. Failure of the belt will lead to vacuum pump stopping functioning leading to loss of vacuum to the booster and hard brakes. 6. BRAKE FLUID RESERVOIR - Stores brake fluid and supplies to tandem master cylinder. Brake fluid reservoir has 2 separate compartments for front circuit and rear circuit. drum_break.exe SAMPLE LEAFLET Disk_break.exe MARSHAL 2000 BRAKES : SERVICE - HYDRAULIC WITH TANDEM MASTER CYLINDER.
