OVERVIEW
Genuine VW/Audi 8E0-611-721-A is an individual left front caliper brake pipe for the original brake arrangements listed below. It renews the formed pipe at the assigned left front hydraulic connection.
Technical details and what is included
- Factory part number: 8E0-611-721-A / 8E0611721A.
- Component type: formed caliper brake pipe.
- Assigned side: left front.
- Required original brake configuration: Audi PR-1LE or the confirmed Passat PR-1ZC application.
- Quantity supplied: one individual pipe.
The archive photo shows the formed pipe and its end fittings. Match the original routing, fitting profile and caliper assignment before ordering. This is a separate component from the flexible brake hose. The corresponding right-side pipe and other front-brake pipe revisions are separately specified.
Common reasons to replace
- A diagnosed leak at the assigned pipe or its fitting.
- Corrosion or physical damage to the original pipe.
- A kinked or distorted pipe no longer follows the required routing.
- Damaged fittings during caliper or hydraulic connection service.
Inspect the caliper connection, flexible hose and adjoining hydraulic components separately. A leaking caliper, damaged mating seat or defective hose requires its own repair. Do not select a pipe solely by model and year when the vehicle has a different original brake option or a modified caliper arrangement.
Vehicle fitment
Check the vehicle's original front-brake PR-code and installed caliper before ordering. The A revision below is assigned to the listed brake configurations; other configurations require separate pipe verification.

Installation and service guidance
Follow the factory brake hydraulic repair procedure for the actual brake system. Keep the connections clean, protect exposed openings during service and inspect the mating fitting seats before assembly.
Install the formed pipe in its prescribed routing without twisting or forcing it into an incompatible caliper arrangement. Start the fittings correctly and tighten them to the vehicle-specific repair specification.
Use the specified brake fluid and bleeding procedure after opening the hydraulic system. Check all disturbed connections for leaks and complete the prescribed pedal, brake-operation and diagnostic verification before the vehicle returns to service.
This listing supplies the pipe only. Caliper, flexible hose, right-side pipe, mounting components and brake fluid are separate. Use the vehicle repair information for exact fitting torque, bleeding sequence and brake-system checks.
