Abstract
A structural unit for a drum brake comprises at least one brake shoe (12) and an adjusting device (32) which comprises an adjusting strut (34), a ratchet-detent wheel mechanism and an adjusting lever (40) which comprises the ratchet (52). The brake shoe (12) has a web (22) against which the adjusting strut (34) rests and on which the adjusting lever (40) is pivotably mounted by means of a bearing pin (56). In order to enable the structural unit with the adjusting device (32) to be easily retrofitted also in the case of older drum brakes the bearing pin (56) is attached to a separate carrier member (66) which can be slid onto the web (22) of the brake shoe (12) in a clamping manner and which comprises at least one first offset (84) which positively engages a recess (86) provided in the web (22). In this manner, the bearing pin (56) is reliably and true-to-position secured at the brake shoe web (22).
