brake pad exchange, since the brake pads can be removed through the frame opening of the brake caliper with ease. When the brake is installed, very unfavorable conditions are present for restoring the brake piston, on account of the brake often being positioned in a poorly accessible location and on account of the small distance between the brake disc and the housing part of the frame caliper. The previously described methods can only be carried out in a very cumbersome and time-consuming manner, which leads to increased servicing costs and also to servicing errors.
Against this background, it is intended to find a servicing method and an associated design of the hydraulic brake with an integrated parking brake, in which the restoration of the brake piston—similarly to the simpleaxial bearing on the end surface of the adjusting nut and raises the latter with its friction cone up from its seat in the piston. The adjusting nut passes out of its frictionally locked state and may now be turned back, as the brake piston is pushed back further, in the non-self-locking thread of the adjusting screw under the action of the axial force.
The restoring of the brake piston is therefore achieved, after the insertion of the spacer, by simply pushing the brake caliper. Alternatively, with the brake caliper fixed, the restoring of the piston may also be effected by exerting pressure on the spacer.
