Remove the brake pads.
Secure the brake caliper in a vise. Filler adapter (1) must face down, so that no traces of thread-locking compound can make their way into the brake caliper when the filler adapter is released.
Caution! Do not allow traces of adhesive to make their way into the brake caliper.
Heat filler adapter (1) to approx. 80°C (1 76°F) and use an open-ended wrench to remove.
Seal the bore in the brake caliper with a paper towel or similar (arrow).
Clean the threads, using a scriber or similar to detach the remains of the adhesive and blow out with a low-pressure jet of air.
Secure brake pistons with resetting tool, BMW No. 341 500.
Inject compressed air through the connecting bore (arrow) in the brake caliper to blow out traces of thread-locking compound that might have made their way into the brake caliper.
Remove brake fluid from the threads.
Install the filler adapter or bleed screw.
Further installation is the reverse of the removal procedure.
