BME041201022103

## Construction

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

## Operation

• By pulling the parking brake lever, 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 brake shoes in the expansion direction. Due to this, the brake shoes press aginst the brake drum, applying braking force.

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

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