Abstract
A method for adjusting clearances between a rotor and opposing first and second brake pads connected to a housing in an electromechanical brake actuator of a vehicle having a motor includes fixing a piston to the first brake pad that is axially displaceable in response to rotation of the motor. The motor is rotated to move the first and second brake pads into engagement with the rotor for braking the vehicle. The motor is then rotated to retract the first brake pad and subsequently the second brake pad until the second brake pad has a predetermined outboard air gap with the rotor. The motor is then rotated to advance the first brake pad until the first brake pad has a predetermined inboard air gap with the rotor.

A method for adjusting clearances between a rotor and opposing first and second brake pads connected to a housing in an electromechanical brake actuator of a vehicle having a motor, comprising:
- fixing a piston to the first brake pad that is axially displaceable in response to rotation of the motor;
- rotating the motor to move the first and second brake pads into engagement with the rotor for braking the vehicle;
- and then
- rotating the motor to retract the first brake pad and subsequently the second brake pad until the second brake pad has a predetermined outboard air gap with the rotor;
- and then
- rotating the motor to advance the first brake pad until the first brake pad has a predetermined inboard air gap with the rotor.
A method for adjusting clearances between a rotor and opposing first and second brake pads connected to a housing in an electromechanical brake actuator of a vehicle having a motor, comprising:
- fixing a piston to the first brake pad that is axially displaceable in response to rotation of the motor;
- rotating the motor in a first direction to move the first and second brake pads into engagement with the rotor for braking the vehicle;
- and then
- rotating the motor in a second direction to retract the first brake pad until the second brake pad has a predetermined outboard air gap with the rotor;
- and then
- rotating the motor in the first direction to advance the first brake pad until the first brake pad has a predetermined inboard air gap with the rotor that is substantially identical to the predetermined outboard air gap.
