Attention! The fluid in the brake hydraulic drive should be changed after 72,000 km or every 3 years.
When removing or replacing the modulator (valve block) ABS systems require air to be removed from each modulator channel.
1. Drain the brake fluid and wipe the master cylinder reservoir.
2. Attach a hose to the bleed nipple and lower the other end into a container with brake fluid.
3. Air removal is performed in the following sequence: left front wheel - right front - right rear - left rear.
4. Ask an assistant to press and hold the brake pedal 3 or 4 times. Loosen the bleed nipple by 1/4 turn. After loosening the nipple, the pedal should move forward.
5. Close the bleed screw and ask an assistant to slowly release the pedal. Check the fluid level in the reservoir and top up if necessary. When removing air, monitor the fluid level in the tank, making sure it does not run empty.
6. Repeat the procedure until the bubbles stop coming out (as a rule, at least 4-5 times), check the pedal travel and stiffness. Excessively long travel and soft pedal indicate the presence of air in the hydraulic drive circuit.
Sequence for bleeding air from the brake system: 1. Front left; 2. Rear right; 3. Rear left; 4. Front left |
Check the fluid level in the reservoir and, if necessary, restore it during bleeding: 1. Top level mark; 2. Tank; 3. Master cylinder |
