OVERVIEW
Correct-length socket-head hardware for the original caliper
N-044-755-3 is the Genuine VW/Audi M8x55 internal-hex bolt cataloged for the original floating front brake caliper arrangement on the confirmed applications below. The specified length distinguishes it from the M8x45 bolt used elsewhere in the same assembly.
Fasteners with a similar diameter can have different lengths, head forms and clamping requirements. Match the original factory number and assigned joint rather than choosing a bolt by appearance alone.
Technical details
- Complete factory number: N-044-755-3.
- Factory specification: M8 × 55 internal-hex socket-head bolt.
- Design: cylindrical internal-hex head with partially threaded shank.
- Quantity supplied: one individual bolt.
The nominal thread and length describe the fastener itself. This listing supplies one bolt rather than the full quantity required for an assembly. Matching nuts, washers, brackets and related parts are separate.
Common reasons to replace
- The original bolt is missing after component service.
- Threads are damaged or will not engage correctly.
- The drive head is rounded or otherwise damaged.
- Corrosion or deformation makes the original fastener unsuitable for reuse.
Check the caliper, guide sleeves, mating threads and related hardware. Binding guides, worn pads or a damaged caliper require separate repairs. Do not interchange the different bolt lengths cataloged within the brake assembly.
Vehicle fitment
Use only at the assigned factory fastening position on the listed applications. These vehicle entries do not establish compatibility with every fastening point on the vehicle.

Installation guidance
Follow the vehicle-specific brake repair procedure. Support the caliper without loading the brake hose, use the correct internal-hex tool and apply the prescribed torque and any locking requirements. Replace fasteners designated for single use.
Confirm caliper movement, hose clearance and correct assembly before reinstalling the wheel. Carry out the required brake pedal and function checks before driving.
Ordering information
