Abstract
A brake system is provided for a wheel rotor having a brake pad associated therewith. The brake system includes a housing defining first and second passages. First and second pistons are provided in the respective first and second passages for selectively moving the brake pad into engagement with the wheel rotor. First and second spindles are threadably coupled to the first and second pistons such that the pistons are axially movable relative to the spindles without the spindles rotating. Each spindle includes first threads separated by first cylindrical roots and each piston is coupled to second threads separated by second cylindrical roots.
