Removing and installing brake caliper (1KX): Audi A1

Step-by-step removing and installing brake caliper (1KX) for the Audi A1: 8 steps. What to remove, in what order, and what to check after.

On the Audi A1 (8X) with the 1KX rear brake, the caliper comes off together with its carrier and pads as one unit by removing the two carrier bolts; the hydraulic hose stays connected, so there is no bleeding involved. Release the parking brake first and take off the rear wheel. If a worn disc has left a lip that stops the assembly sliding off, take the pads out before trying again. The points that matter are supporting the caliper instead of letting it hang on the hose, using new carrier bolts on refitting, and checking the hose is routed without kinks or twists once the assembly is back over the disc.

8 steps

🧭 Before you start

Release the parking brake, remove the rear wheel and undo the carrier bolts. Pull caliper, carrier and pads off the disc together, removing the pads first if the disc lip prevents it, and support the caliper so the hose takes no load. Slide the assembly back over the disc, fit new carrier bolts, check the hose routing and refit the 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.
