ABSTRACT:
An abutment assembly for an internal shoe drum brake, particularly a vehicle wheel brake, comprising opposed abutment members for engagement with respective brake shoes and an arrangement for transmitting forces between the abutment members. The arrangement comprises a deformable member contained within a recess in one abutment member and sandwiched between the abutment member and a piston in force transmitting relation with the other abutment member. The deformable member has different areas of engagement with the piston and the one abutment member so that only a part of the thrust applied to one abutment member is transmitted to the other abutment member.
