Procedure for changing brake fluid





Fill reservoir to its top edge with new brake fluid. Connect a bleeding device to the brake fluid reservoir.

Switch on the bleeding device. Bleeding pressure approximately 2.0 bar.

Continue bleeding at the brake calipers (no special sequence).

Open each bleeder valve until clear, bubble-free brake fluid emerges or the appropriate change quantity per brake caliper has been reached (approximately 250 cm [sup3 ]). Make sure that brake fluid is drained at both bleeder valves on each brake caliper.

Use a collecting bottle to accurately check the escaping brake fluid for cleanliness, lack of air bubbles and to determine the brake fluid used.

Some brake fluid is also drained off at the bleeder valve of the clutch slave cylinder (approximately 50 cm [sup3 ]).





Switch off and disconnect the bleeding device. Correct the brake fluid level if necessary.
