A self-energized disk brake assembly includes gain stabilization features for controlling the multiplication of applied force against a rotatable brake member. The brake assembly includes a first brake pad supported about a first pivot and a second brake pad supported about a second pivot. An actuator applies a force to drive the brake pads into the rotatable brake member. Frictional force between the brake pads and the rotatable brake member pulls the brake pads into further engagement generating an increase in braking force from self-energization. A position of the first and second pivots is adjustable to control the amount of braking force generated from self-energization.

Gain stabilizing self-energized brake mechanism

A brake assembly has a caliper with a first brake pad and a second brake pad. The first brake pad is moveable relative to the caliper. A brake actuator moves the first brake pad and has a first threaded member and a second threaded member. The first threaded member has first thread characteristics for moving the brake actuator at a first speed and a first force. The second threaded member has a second thread characteristics for moving the brake actuator at a second speed and a second force. The first speed is greater than the second speed while the first force is lower than the second force.
