ABSTRACT:
A single-piece housing fixed brake caliper is provided with one relatively large piston bore on one side of the rotor and two relatively smaller piston bores on the opposing side of the rotor. The sum of the areas of the two relatively smaller pistons is equal to the area of the one relatively larger piston to provide balanced braking. The side of the caliper housing opposite the two relatively smaller bores contains two access cavities that provide clearance for the tooling that is necessarily positioned within the caliper to machine the bores. Similarly, the side of the caliper housing opposite the one relatively larger bore contains one access cavity that provides clearance for the tooling.
