Abstract
A disc brake caliper which includes a cooling fluid gallery which at least partially surrounds at least one of the brake operating piston and cylinder assemblies to cool the hydraulic fluid of any such assemblies. The gallery is constructed to provide thin side walls for piston and cylinder assemblies to maximize the cooling of the assemblies.
Claims4
A disc brake caliper having two limbs which in use straddle a brake disc to support friction pads on each side of the brake disc for engagement with opposed sides of the disc, two or more hydraulic piston and cylinder assemblies in each limb of the caliper for operation of the caliper via a brake applying circuit, a cooling circuit separate from the brake applying circuit for the circulation of coolant within the caliper, the cooling circuit including an internal gallery in each limb of the caliper which at least partially encircles a cylinder of each assembly in the limb and the gallery in one limb being interconnected with the gallery in the other limb, and pumping means for circulating coolant around the separate cooling circuit which includes both galleries.
