ABSTRACT:
A brake shoe (1) for a railway brake has a dovetail slot (4) in its front face for receiving a projection (3) of complementary shape on a brake pad (2) for mounting the pad on the shoe, and a retainer (6) slidably mounted in an aperture in the shoe and having a tongue (8) which projects into the slot for retaining the pad on the shoe, the retainer being biased by leaf-springs (10) fixed to the rear face of the shoe into an operative position so that danger of the retainer being left in a retracted position after a pad replacement operation is eliminated.
