OVERVIEW
N-911-746-01 Genuine VW/Audi Rear Brake Caliper Carrier Bolt - M12 x 1.5 x 38 mm. This fastener attaches the rear brake caliper carrier at the specified mounting point. The carrier supports the brake pads and establishes their position around the rotor, so its fastening hardware must match the original brake assembly.
Technical details
- OEM part number: N-911-746-01 / N91174601.
- Internal multi-point drive and a collared head, visible in the original product photo.
- Thread diameter and pitch: M12 x 1.5; catalog length: 38 mm.
- Rear caliper carrier / bracket mounting application; guide-pin hardware is a different component.
- Supplied as one bolt. Mounts, brackets, washers not integral to this bolt, and other repair components are separate.
Common reasons to replace
Replace a bolt with a damaged internal drive, compromised threads, substantial corrosion or a damaged seating surface. Carrier removal during brake repair is also a reason to review the applicable fastener replacement requirements. A rounded drive recess can prevent controlled removal and tightening; an unsuitable bolt can bottom out or fail to clamp the carrier correctly.
Installation and service notes
Support the caliper during disassembly so its weight does not pull on the brake hose. Inspect the carrier, mounting threads and bolt seating surface before reassembly. A new bolt will not repair damaged threads in the mounting component. Use the specified drive bit fully seated in the head, and follow the vehicle repair procedure for fastener renewal, tightening sequence and any required thread treatment.
Compare the part number and the original attachment location before ordering. Different brake packages and nearby fasteners can look similar while using different lengths, head designs or tightening requirements. Do not substitute this carrier bolt for a slide-pin bolt or assume that every mounting point on the rear brake assembly uses it.
