Patent ID: 7913821

Claim:
A method of controlling a braking system of a road-going automobile, comprising: providing the vehicle with front and back brakes in which the front brakes include a pair of rotatable wheel hubs, at least two spot-type brake discs mounted on each of the wheel hubs and supported for rotation with the wheel hubs and for axial sliding movement on the wheel hubs and each brake disc presenting opposite circumferentially continuous annular braking surfaces, at least three spot-type friction elements mounted on a stationary brake caliper associated with each wheel hub and interleaved with the associated brake discs and being circumferentially discontinuous so as to overly only an angular sector of the annular braking surfaces of the brake discs, and with at least two of the friction elements being axially slidable on its respective brake caliper for engaging and disengaging the braking surfaces of the brake discs; providing a rotating electric actuator having a stator and a rotor with the electric actuator operative to move the friction elements into braking engagement with the brake discs; and controlling the attitude and movement of the brake discs with respect to the wheel hub and controlling the attitude and movement of the friction elements with respect to the caliper to maintain the brake discs and friction elements in parallel alignment during sliding movement into and out of braking engagement with one another.
