An automatically adjustable internal shoedrum brake mechanism comprises a brake shoe 18 having a web 17, an hydraulic actuating plunger 15 acting on one end of the web, fixed members 36, 37 adjacent either end of the web against which members 35, 49 on the web abut, automatically extensible means 38, carrying member 49, which extend on rotation of a member 45, an adjusting lever 53 pivoted relative to the web with an end portion 55 engaging member 45 to rotate it and actuating means 68, 74, 76 responsive to a degree of movement of one end of the web to pivot the adjusting lever. As shown, a backing plate 12 carries two wheel cylinders including plungers 15, 16, retracting springs 23, 24 and has lugs 21 on which the shoe slides and is held against by a spring assembly 22. The means 38 comprise a cylinder 39 welded to the web and containing an antifriction sleeve 44 supporting a sleeve 45 in threaded engagement with member 49, the latter engaging the web to prevent its rotation. Sleeve 45 includes a star wheel 47 rotated by a cam portion 55 of lever 53 pivoted with an operating lever 56 on the cylinder 39. A compression spring 57 extends between the levers 53, 56 and is attached to both, and a tang on lever 53 engages lever 56 to transmit rotation. Lever 56 is biased by a spring 65 and moved by a linkage comprising links 68, 76 and a bellcrank 74 pivoted on the web. One end of link 76 is secured to the backing-plate and link 68 engages a slot in lever 56. On actuation with the drum rotating clockwise the shoe will tend to rotate in that direction until members 37, 51 abut. Surfaces 35, 36 move apart causing the linkage to rotate levers 56, 53 and if sufficient wear has occurred lever 53 engages the next tooth on the star wheel. On release, springs 23, 24 prevent movement of the star wheel. When the brake is actuated with the drum rotating anticlockwise members 37, 51 separate and spring 65 can turn levers 56, 53, causing the star wheel to rotate and extend the means 38. Crank 74 may be replaced by a lever pivoted at 78 near the end of the web such that the surface near 75 abuts the backing plate surface 35. On actuation, spring 65 moves levers 56, 53 clockwise and on release the link 68 returns the levers thereby rotating wheel 47. The link includes a spring-loaded device so that if springs 23, 24 prevent wheel 47 rotating when the brake is released the spring is compressed and turns the wheel when the brake is subsequently applied. In other embodiments levers 53, 56 are replaced by a single lever, the linkage by a cable and spring 65 by a coil spring on pivot pin 54. In Fig. 6, the adjusting lever 349 is pivoted about an inwardly projecting portion 347 of the shoe rim and is biased by a spring 355. A pin on the cylinder 337 extends through a slot 357 in the lever 349 and U-shaped members 367, 373 attached to lever 349 and the back plate form the actuating means.
