The bearing bush 28 is used to protect the bearing 11 ′, 12 ′ locked at its end.

In the embodiment according to FIG. 1, the two bearings 11, 12 and 16, 17 must have axial directions that are as aligned as possible to be ordered; it can be useful for this purpose, in particular, for the bearing, which is less stressed by the braking torque 16, 17 or at least one of their ropes, the pin 16 or the bore 17, adjustable in a manner to be explained later to arrange.

According to Pig. S also have an articulation arm 25 which overlaps Eadsatzwelle 6 and which, according to Pig. 9 is cranked in addition to the brake disc 9 and thus keeps the tilting moment acting on the brake caliper ok around the pivot axis of the only indicated pivot arm 25 on the steering lever 26 due to the lateral distance between the center points of the Seibbeläge 23 and 2 ^. The klein® tilting moment can be absorbed without difficulty by the bearing 11, 12 of the brake caliper 10, which is designed, for example, in accordance with FIG. From Fig. 8 and 9 it can be seen that the steering lever 26 is relatively long. This ensures that displacements of the brake caliper 10 caused by wear of the brake lining 24 have almost no effect on the braking torque support of the brake caliper 10, in particular on the inspection of the supporting force transmitted by the steering lever 26. 8 and 9, the Yerbindungsscrews 49 for clamping the two brake caliper halves and secured by spring clips 50, milrtels grip sections 51 easily removable bolts 52 for holding the brake pads 23 xmd 2Pt can be seen .

The spring 55 is supported, on the one hand, against the free end of the spring cage 54 and, on the other hand, against the head part of the tie rod 56, which is mounted in the bore 53 in a displaceable manner and can be caught by a locking ring 51.
