The brake system provides two systems, a foot brake and a parking brake.
In the foot brake system, the oil pressure which is generated in the master cylinder when the brake
pedal is depressed is transmitted to the wheel cylinders. The piston of the wheel cylinder presses
the brake shoes and then moves outward causing contact with the drums and braking force is
obtained. In the parking brake system, the force is transmitted to move the brake shoe through a
brake cable to activate the brake when the brake lever is operated.
The wheel brake is a dual servo type in which the actuating force is applied to both the primary and
secondary shoes. Even if the applied force is small, a large braking force will be obtained.
These brakes are equipped with self adjusters which continuously adjusts the brakes in small
increments in direct proportion to the wear of the linings.
