Caution: Do not empty the reservoir completely to prevent air from entering the brake system.
Fill the reservoir with fresh brake fluid up to the MAX mark.
Attach a clean hose to the right rear brake caliper bleed valve and place a suitable container underneath.
Have the assistant press the brake pedal several times until pressure is built up. While holding the pedal down, loosen the bleed valve with the open-end wrench (1) and allow the brake fluid to flow out through the hose. Tighten the valve when the pedal is at the floor. Remove your foot from the pedal. Repeat this process until fresh brake fluid, which is lighter in colour, starts to flow out of the hose.
Tighten the air bleed valve and fill the tank with fresh fluid.
Remove brake fluid from the remaining calipers in the same manner.
Caution: The escaping brake fluid must be clean and free of bubbles.
Caution: Replace the brake fluid in the clutch hydraulic system in the same way.
Brake fluid is poisonous and should be drained in special places, but under no circumstances into the household sewer.
