Required special tool:
- round key for unscrewing the bolts of the exhaust device;
- transparent plastic hose.
Required wearing parts:
- approximately 0.5 liters of DOT 4 brake fluid.
Brake fluid absorbs moisture from the air through the pores of the brake hoses, as well as through the reservoir vent. Because of this, over time, the boiling point of the brake fluid decreases. If the brakes are heavily loaded, this can lead to the formation of steam bubbles in the brake pipelines, which greatly impairs the functioning of the braking system.
Regardless of the mileage, change the brake fluid, if possible, in the spring, every two years. Change the brake fluid at shorter intervals if you travel frequently in mountainous areas.
Be careful when handling brake fluid.
Mark the brake fluid level in the reservoir with a felt strip. After changing the brake fluid, restore it to the original level again. This prevents the hydraulic brake reservoir from overflowing when replacing the friction linings of the brake pads.
1. Using a suction bottle, pump out the brake fluid from the hydraulic brake reservoir to a level of approximately 10 mm.
Attention! Do not empty the reservoir completely so that air does not enter the brake system.
2. Fill the reservoir with new brake fluid up to the mark "max".
3. Slide a clean hose over the breather valve on the right rear disc brake caliper, and place a suitable container.
4. Have an assistant depress the brake pedal several times until back pressure builds up. Instruct to depress the brake pedal, at the same time open the breather valve and let the brake fluid flow out through a transparent hose. Close the breather valve, if the pedal is adjacent to the base of the monocoque, remove your foot from the pedal. Repeat this operation (about 10 times) on each breather valve until new brake fluid comes out. New brake fluid can be identified by its lighter color.
5. Close the breather valve, fill the reservoir with new brake fluid.
6. Also pump out the old brake fluid from other disc brake calipers.
Attention! In any case, the bleed brake fluid must be clear and free of bubbles.
Attention! Dispose of old brake fluid as special waste.
