Vehicle brake system

Abstract

A vehicle brake system, comprising: a brake pad (10), being moveable between a braking position and a retracted position, a piston device (20) which is moveable over an operational stroke to move the brake pad from the retracted position into the braking position, which piston device comprises a first engagement surface (25), a retractor (30) which is adapted to move the piston device over a return stroke, thereby moving the brake pad from the braking position into the retracted position, a stop (40) which is in engagement with the first engagement surface (25) of the piston device (20) at the end of the return stroke, which stop (40) is arranged to prevent movement of the first engagement surface 825) past the stop in the direction of the return stroke, and wherein the stop (40) is moveable by the piston device (20) in the direction of the operational stroke of the piston device.
