Brakes Construction

When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pistons (two
in front disc brake and four in rear drum brake).
The master cylinder is a tandem master cylinder. Brake pipes are connected to the master cylinder and they make two
independent circuits. One connects front right & rear left brakes and the other connects front left & rear right brakes.
In this brake system, the disc brake is used for the front wheel brake and drum brake (leading / trailing shoes) for the
rear brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes of rear drum brake are used for both parking and foot brakes.
NOTE
• The figures show LH steering vehicle.
• The difference between RH steering vehicle and LH steering vehicle is the location of the brake
master cylinder, the brake booster and ABS (ESP®) hydraulic unit / control module assembly.
