The invention concerns a, preferably pneumatic, disc brake (1), in particular for a motor vehicle, comprising a brake application device, preferably with a brake rotary lever (9), at least one spindle unit (5, 5') having at least one threaded pipe (6, 6') with an external thread (6a, 6'a) cooperating with an internal thread of a bridge (7), and at least one bidirectional wear adjustment device (10) which is coupled to the brake application device, preferably to the brake rotary lever (9). The bidirectional wear adjustment device (10) comprises an adjustment arrangement (8) and at least one preloading arrangement (20, 20') which is designed to influence a flank position of a thread pairing of the external thread (6a, 6'a) of the at least one threaded pipe (6, 6') and the associated internal thread of the bridge (7). The invention also concerns a bidirectional wear adjustment device for this type of disc brake (1). |
