Abstract
A disc brake having a caliper straddling a rotor; a fixed carrier, an actuator comprising a primary cylinder located in the caliper and closed by a piston; a guide arrangement including first and second pins for allowing the caliper to slide relative to the carrier on actuation, the first and second pins have a bound end fixed to the caliper and a free end respectively retained in first and second bores in the carrier by annular roll-back seals to define first and second auxiliary or secondary hydraulic cylinders. Inboard and outboard friction pads are positioned on opposite faces of the rotor by the piston and the caliper. In operation, the caliper, cylinder, and outboard brake pad are hydraulically moved to engage the outboard brake pad with the rotor while the primary cylinder hydraulically moves the inboard brake pad into engagement with the rotor to effect a brake application.
