ABSTRACT:
A shoe gap adjusting device includes a piston for pressing a brake shoe through a piston head, having a projecting end part with a boot cover for protecting an elastic boot that seals an end part of a cylinder body. A shoe gap adjusting ring is fitted on the end part of the piston in a non-rotatable manner. A elastic piece at the inner periphery of the cover axially extends through a cut-out in the ring and elastically supports the outer peripheral surface of the head so that the piston head is elastically attached to the piston. A tool can be inserted through an opening and engaged with an outer peripheral cut-out of the ring, for rotating the ring relative to a bolt and performing an adjustment of the shoe gap. The device simultaneously allows the protection for the elastic boot and realization of rotational operability of the shoe gap adjusting ring by the tool.
