With Vacuum Brake Booster

Changing Brake Fluid (vacuum brake booster)

Important notes

Use only new DOT 4 brake fluid. Observe change interval and brake fluid quality.
Total brake fluid quantity approx. 1 liter.


Procedure for changing brake fluid

- Fill reservoir with new brake fluid up to upper edge. Connect bleeder device to reservoir.

Clamp shut overflow hose/venting hose with a hose clamp. The overflow hose/venting hose has been omitted as from October 1995.

Switch on bleeder device. Bleeder pressure approx. 1.5 bar.

- Proceed with brake fluid change on the individual calipers (no particular sequence required).

Open each bleeder valve until clear, bubble-free brake fluid escapes or until the respective change quantity per caliper is reached (approx. 250 cc). Make sure all brake calipers are bled on both bleeder valves.

- To monitor the escaping brake fluid for cleanliness, freedom from air bubbles and to determine the brake fluid used, use a recipient bottle.

- Also drain some brake fluid at the bleeder valve of the clutch slave cylinder (approx. 50 cc).





- Switch off and disconnect bleeder device. Top up brake fluid if required.
