OVERVIEW
Maintain free movement of the original floating brake caliper
251-615-219 is the Genuine VW/Audi brake caliper guide pin for the specified original floating-caliper installations. The smooth guide surface supports controlled sliding movement between the caliper and its carrier as the brake is applied and released.
A corroded, worn or damaged guide pin can prevent the caliper from moving freely. That can contribute to uneven pad wear, brake drag or inconsistent release. The guide pin must match the installed caliper design; a similar-looking pin is not sufficient evidence of compatibility.
Technical details
- Complete factory number: 251-615-219.
- Factory specification: factory caliper guide pin, complete number 251-615-219.
- Design: metal guide pin with a smooth sliding section, threaded end and internal drive, as pictured.
- Quantity supplied: one individual caliper guide pin.
One individual guide pin is supplied. Boots, bushings, grease, caliper, carrier, pads and discs are separate. Confirm the number of pins required for the repair and inspect the entire guide arrangement.
Common reasons to replace
- The sliding surface is pitted or corroded.
- The pin is worn, bent or mechanically damaged.
- A damaged drive prevents correct removal or installation.
- Diagnosis identifies restricted caliper movement associated with the guide pin.
Inspect the guide bushings, protective boots and carrier along with the pin. Uneven pad wear can also result from piston, hose or other brake faults. Replace damaged related components and diagnose the cause of binding before assembly.

Installation guidance
Follow the vehicle and caliper-specific brake service procedure. Support the caliper without straining the hose, clean the specified guide surfaces and use only the lubricant prescribed for that caliper design. Follow the correct fastener renewal and tightening requirements.
Confirm free caliper movement, correct boot seating and secure assembly. Perform the prescribed brake functional checks before returning the vehicle to service.
