Abstract
An electromechanical brake apparatus includes a housing supporting an inboard brake pad and an oppositely facing outboard brake pad for selective frictional contact with a rotor interposed longitudinally therebetween. An adjuster ramp assembly indirectly receives torque from the motor unit. A spindle is provided for selectively moving the inboard brake pad longitudinally. The spindle is operatively connected with the adjuster ramp assembly to indirectly receive torque from the motor unit therethrough. A leading ramp assembly is configured to transmit applied torque from the motor unit to the adjuster ramp assembly via at least one ramp ball longitudinally interposed therebetween. A predetermined amount and direction of torque is applied to each of the adjuster ramp assembly and the leading ramp assembly to assist with a selected one of (1) service brake application and (2) service brake release functions. The electromechanical brake apparatus is operative, at different times, for both functions.
