–  Open bleeder valve on brake caliper.
–  Fully depress brake pedal.
–  Close bleed valve with pedal held down.

This bleed sequence must be carried out 5 times per brake caliper.

3 -  Rear left wheel brake cylinder
4 -  Rear right wheel brake cylinder

Use suitable bleeder hose. It must sit tightly on bleeder valve so that no air can enter brake system:

  Note
A road test must be carried out after the brakes have been bled. When doing this an ABS regulation must be performed at least once!
