Abstract:

A disc brake caliper is mounted with a rollpin or similar sleeve secured between the brake torque transmitting member and the brake torque receiving member. The rollpin sleeve is also positioned about the brake hose applying braking pressure to the caliper assembly so that when brake actuation occurs the caliper brake torque reaction compresses the rollpin, closing the brake hose passage completely when the maximum permissible braking torque is exerted. Thus the brake actuating pressure and the resulting braking effort are limited so that the wheel does not reach incipient wheel lock at maximum allowable braking effort on dry pavement.
