ABSTRACT:
An adjuster strut for a vehicle drum brake comprises a non-rotatable bar abutting one of the brake shoes, and internally screw-threaded barrel non-rotatably mounted on the bar, a screw-threaded rod screwed into the barrel and being fast with a ratchet wheel, the wheel being arranged to be rotated by a pawl in the event of excess shoe travel, such rotation of the wheel screwing the rod out of the barrel to increase the strut length, and an abutment member which abuts the other shoe and on which the ratchet wheel is rotatably mounted. In order to ensure that the strut is clear of a wheel hub even in the worn condition of the brake shoes, the bar extends over the major part of the length of the strut and is flat.
