3. Continue bleeding at the brake calipers in the sequence: Sequence: Rear right / rear left / front left / front
right.
4. Open each bleeder valve until clear, bubble−free brake fluid
emerges.
5. Use a transparent hose and a collecting bottle to check the escaping brake fluid accurately for cleanliness,
lack of air bubbles and to determine the brake fluid used.
After installing a new brake master cylinder and/or a new hydraulic unit, do the following while bleeding:
• Open the right rear bleeder valves, then fully depress the brake pedal several times.
• Hold for 2 − 3 seconds after each depression, then release slowly.
• Repeat this procedure in the sequence rear left / front right / front left. This will remove all air bubbles
(from the primary circuit).
Note
• Also carry out this procedure if the brake hydraulics was largely empty or if after bleeding residual air
can be detected by excessive brake−pedal travel!
6. Switch off and disconnect the bleeding device. Correct the brake fluid level if
necessary.
