Abstract:
A disk brake arrangement includes a retraction mechanism for positively retracting brake pads after application to the brake rotor. Preferably the retraction mechanism is energized by movement of a hydraulically actuated piston for applying one or more brake pads. In an embodiment a drag sleeve is associated with the piston to compensate for brake pad wear and provide a more constant retraction force for retraction of the brake pads.

Claim (Index 7):
A disk brake arrangement comprising a brake rotor and an associated brake caliper, said brake caliper positioning opposed brake pads either side of said brake rotor for applying a braking force to said brake rotor;\n said brake caliper including a hydraulically actuated piston for actuating said brake arrangement by moving said piston within a cylinder towards said brake rotor to apply said brake pads against said brake rotor when sufficient hydraulic pressure is applied to said piston; said piston includes a hydraulic seal between said piston and said cylinder; said piston including a retraction mechanism cooperating with said piston that stores retraction energy during application of said brake pads into engagement with brake rotor and uses said energy to retract said brake pads when said sufficient hydraulic pressure is removed; said retraction mechanism includes an adjusting member cooperating with a threaded portion of said cylinder, a distortable sealing ring located between said adjusting member and a drag ring on an exterior surface of said piston; said distortable sealing ring gripping said piston and, due to engagement with said drag ring, elastically distorting during actuation of said braking arrangement to store retraction energy; and wherein said distortable sealing ring, when said sufficient hydraulic pressure is removed applying said stored retraction energy to said drag ring and thereby retracting said piston.
