Abstract

The brake drum has a revolving central cylinder. The brake shoes are in two parts which are joined together on one side at the swivel (15). Each shoe is fitted with a friction pad (20) on its inner surface. The shoes are separated at the opposite end by a hydraulic cylinder (17) held between the jaws (13a, 14a) and fitted with adjustment screws (18, 19). The shoes cross over to give a central pull and the return spring (16) assits the movement.
