ABSTRACT:
An adjusting and centering mechanism for a sliding advance lock of a servo drum brake, has a pawl drive which cooperates with toothed adjusting wheels. The pawl drive is actuated when the sliding advance lock is axially displaced in consequence of actuation of the brake. When the brake is actuated the pawl drive produces a force-dependent adjustment which compensates for wear of the brake linings. The pawl drive has two spring-loaded two-armed levers. A spring engages the arm of each adjusting lever which bears an abutting-region, and the spring holds the lever abuttingly against an element connected to the sliding advance lock, so that the spring tends toward relaxation as the element is displaced axially.
