BRAKES 9 1.6. BRAKE HYDRAULIC LINES SCHEMATIC CIRCUIT DIAGRAM OF ABS BRAKE LINE General: Vehicle braking is provided by Disc Brakes on the front wheels and Drum Brakes on the rear wheels. Under normal brake operation, brake pedal movement is assisted by the Booster assembly and transmitted to the Tandem Master Cylinder (TMC) assembly. The TMC assembly converts brake pedal movement to hydraulic pressure. Vacuum for the brake servo assembly is obtained from the engine inlet manifold (for petrol engines) or a vacuum pump (for diesel models), through a vacuum line and non-return valve. Anti-lock braking system consists of a Hydraulic modulator with integrated Electronic control unit, four-wheel speed sensors (one located at each wheel) and 2 warning lamps in the instrument cluster (1(yellow for ABS and 1(Red) for EBD). The brake pipes are connected to the brakes through the ABS ECU / HCU. They make two independent circuits diagonally split. The primary circuit connects the Front Right and the Rear Left brake while the secondary connects Front Left and Rear Right brake through ABS unit. Internal to the Hydraulic modulator each brake has a pair of solenoid valves, one inlet and one outlet; these are activated by the ECU to control the brake force on individual wheels whenever required.
