Abstract: A parking brake (10) having a drum containing first and second brake shoe portions (11, 12), a handbrake lever (18) pivoted (19) adjacent one end on one (11) of the brake shoe portions and a strut (20) extending between a first abutment on the handbrake lever and a second abutment (21) on the other (12) of the brake shoe portions. Pivoting of the handbrake lever relative to said one brake shoe portion (11) moves the strut (20) which in turn moves the other brake shoe portion (12) away from said one brake shoe portion to bring the shoe portions into contact with the drum thus applying the parking brake. One of the abutments is in the form of a biased wedging means (21) which acts on the strut (20) to take up all play in the thrust path between the handbrake lever (18) and the other brake shoe portion (12) via the strut.

Abstract: A brake adjuster for adjusting the working clearance of the shoes of an automotive drum brake, the adjuster including three co-axial elements a first rod element (25) having a head portion for engagement with a first brake shoe and a threaded stem portion, an intermediate element (28) in threaded engagement with the first rod element and a second rod element (27) having a head portion for engagement with a second brake shoe and a stem portion slideably connected with the intermediate element (28) and free to rotate relative thereto. A reaction member (30) is mounted on the intermediate element (28) and a ring gear (35) is provided on the intermediate element which is axially located between the second rod element and the reaction member. A leaf spring (31) acts between the second rod element (27) and the reaction member (30) for pushing the second rod element away from the intermediate element (28).
