ABSTRACT:
A friction pad assembly for a rail vehicle brake comprises a pad of friction material carried by a rigid backing plate, and the backing plate is detachably mounted on a shoe. A part-circular notch at one end of the shoe receives the stem of a headed stud which acts as an abutment for that end of the backing plate, and the backing plate is urged into engagement with the stud by means of a keeper which acts on the opposite end of the backing plate. The keeper comprises a stop member in combination with a relatively movable resilient abutment comprising a strip of metal which is bent into a loop and of which a forward terminal projection of part-circular outline is received in a notch of complementary outline in the other end of the backing plate.
