Parking Brake (Brake-lock) Operation
The brake-lock arm turns through the brake-lock cable as soon as pulling the brake-lock lever. The turning movement
is converted to axial movement by the brake-lock adjuster connected to the body with the thread “A”.
The axial movement transmits automatically from sleeve piston to adjust-bolt. The adjust-bolt presses brake pad to
brake disk through the adjust-nut/caliper piston. In this bout, the adjust-bolt and adjust-nut move together with the
relation as shown in the figure.
When releasing the brake-lock lever, each part return to home position, the caliper piston will be returned by an
elasticity transform of piston seal, the adjust-bolt will be returned by the adjust-bolt spring, the brake-lock adjuster will
be returned by the return-spring.
