Abstract:
1. A control system for a disc brake adjuster mechanism, the control system comprising: an electric adjuster motor for operable connection to the disc brake adjuster mechanism and for driving a friction lining towards and away from a disc brake rotor to maintain a predetermined running clearance between the disc brake rotor and the friction lining when a brake is not applied; a brake displacement sensor; and a controller programmed to determine a brake displacement at which a predetermined load on the friction lining is achieved due to contact with the disc brake rotor, wherein the predetermined load is determined from a current parameter of the electric adjuster motor, and wherein the control system is programmed to signal operation of the electric adjuster motor and to measure the current parameter of the electric adjuster motor while the brake is being released in order to determine the predetermined load, and the control system is further programmed to measure the brake displacement at the predetermined load while the brake is being released.
