•  The parking brake mechanism of vehicles with rear disc brakes mainly consists of a disc plate with parking drum function, parking brake shoe, and operation lever.

•  By depressing the parking brake pedal, the operation lever is moved via the parking brake cable in the direction shown by the arrow in the figure. Due to the movement of the operation lever, the right and left adjusters press the parking brake shoes in the expansion direction. Due to this, the parking brake shoes press against the brake drum, applying braking force.

•  When the parking brake is released, the force of the parking brake shoes returning to their original position is utilized.

•  The parking brake shoe clearance is adjusted by the rotation of the adjuster screw.
