Patent ID: 6938737

Claim:
A variable self-energization system for a brake assembly having a caliper, a rotor, and a brake pad, the self-energization system comprising: a first self-energization member movably mounted to the caliper and having a first working surface with a first angle of inclination and a second working surface generally opposite the first surface and with a second angle of inclination, the first and second angles of inclination both being non-zero and being different from one another such that the first and second working surfaces are non-parallel with one another; a reaction member mounted to the caliper and contacting the first working surface; a second self-energization member contacting the second working surface; and a controller assembly comprising a first motor connected to the first self-energization member and operative to move the first self-energization member, a second motor connected to the second self-energization member and operative to move the second self-energization member, and a controller controlling the first motor and the second motor; whereby said motion of the first and second self-energization members causes the first self-energization member to be displaced in a direction which varies a force applied by the brake pad to the rotor.
