- Carefully install brake caliper. Do not twist brake line when installing brake caliper. — Carefully press brake caliper (with brake pads fitted) over brake disc.
- After installing brake caliper, firmly depress brake pedal several times with vehicle stationary, so that the brake pads are properly seated in their normal operating position.
📋 Procedure
- Raise the vehicle.
- Remove wheels. [Note: Press brake pads back using piston resetting appliance T10145. To do so, position the tool at the backing plates of the installed brake pads and press the brake pads back carefully.]
- ⚠ 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 (from vehicle tool kit) into the wheel bolt holes when removing and fitting a wheel. Insert the long assembly pin into the top hole. — Remove retainer for brake line at wheel bearing housing
- Remove bolts (3).
- ⚠ Carefully detach brake caliper. Do not twist brake line when detaching brake caliper. — Carefully detach brake caliper with brake pads and pivot to one side. [Note: Brake caliper must not be dismantled. Do not loosen any bolts on the brake caliper.]
- ⚠ Carefully install brake caliper. Do not twist brake line when installing brake caliper. — Carefully press brake caliper (with brake pads fitted) over brake disc.
- Secure brake caliper with new bolts (3).
- Secure retainer for brake line on wheel bearing housing. [Note: After installing brake caliper, firmly depress brake pedal several times with vehicle stationary, so that the brake pads are properly seated in their normal operating position.]

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.
