- Ring wrench 10 mm for air outlet valves.
Consumables:
- Brake fluid specification DOT4.
Brake fluid removes moisture from the air through the pores of the brake hoses and through the vent in the cap of the expansion tank. Therefore, over time, the boiling point of the brake fluid decreases. When the brake system is heavily loaded, therefore, steam bubbles can form in the pipes, which has a strong influence on the operation of the brake system.
Brake fluid should be changed every 2 years, regardless of mileage, preferably in the spring.
Be careful when handling brake fluid.
Suck out the brake fluid from the reservoir to a level of approximately 10 mm.
Attention: Do not empty the expansion tank completely, as air can get into the brake system.
Fill the reservoir with new brake fluid up to the MAX mark.
Put a clean hose on the right rear brake caliper on the bleeder valve, substitute a vessel.
Have an assistant press and hold the brake pedal.
Open the air release valve and "pump" about 10 times the brake pedal.
Close the bleed valve. Top up the expansion tank with new brake fluid.
In the same way, pump out the old brake fluid from the remaining brake calipers:
- 1. rear right wheel;
- 2. rear left wheel;
- 3. front right wheel;
- 4. front left wheel.
Caution: The fluid that flows out must be clean and free from bubbles.
Take old brake fluid to a local collection point for special waste.
Attention: Do not store old brake fluid in food containers and in places accessible to children. Danger of poisoning!
