Servicing front brakes (PR 1LP)
Special tools and workshop equipment required
Torque wrench
V.A.G 1331
Torque wrench
V.A.G 1410
Brake pedal actuator
V.A.G 1869/2
Note
Install all parts supplied in repair kit.
After renewing brake pads, depress brake pedal firmly several times with vehicle stationary so that the pads are properly seated in their normal operating position.
To draw off brake fluid from brake fluid reservoir use a bleeder bottle which is used only for brake fluid. Brake fluid is poisonous and must NOT be drawn off by sucking through a hose.
Caution
On vehicles with ceramic brakes the wheel must not be allowed to drop onto the brake disc. This would cause irreparable damage to the disc. Screw two assembly pins into the wheel bolt holes when removing and fitting a wheel.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
