Abstract
The present invention provides a pad retaining plate assembly which can be operated to allow for pad replacement without any part having to be removed and without the inconvenience of having to deal with nuts, bolts, etc. The pad retaining plate assembly comprises a latch member which is movable relative to a guide, the guide being secured to a brake shoe so that the latch member can then attain an operative position wherein the latch member projects through an aperture in the brake shoe. A spring also mounted on the brake shoe is arranged to grip the latch member and to hold the latch member in the said operative position when this position is attained. The latch member can be moved away by a simple tool against the grip of the spring to facilitate pad replacement.
