System Operation

When pulled in the direction "A", the parking lever presses the secondary shoe against the brake drum using the lever/shoe joint "B" as a fulcrum and pushes the strut in the direction "C". The strut ,in turn, presses the primary shoe against the brake drum. Counter force "D" to the primary shoe is transmitted again to the secondary shoe through the fulcrum "B". The secondary shoe contacts the drum thereby producing braking effect. Clearance which may result from worn parking brake shoe lining can be adjusted by turning the adjusting screw.
