Examination
1. The procedure in question refers to bleeding the entire system, but if the seal is broken in only one of the brake system circuits, then only that circuit should be bled. Such partial bleeding of the brake system is permitted only if a minor leak of brake fluid occurred when removing the brake pipe or hose.
CAUTION: During the bleeding procedure, maintain the brake fluid level in the brake system reservoir between the minimum and maximum level marks by adding fresh brake fluid.
Adjustment
1. Raise the front and rear of the vehicle.
CAUTION: Do not work under a vehicle supported only by a jack. Always support the vehicle with safety stands.
2. Check the tightness of the connections of the pipes and hoses of the system and make sure there are no signs of fluid leakage.
3. Add brake fluid to the reservoir up to the "MAX" mark.
MAINTENANCE, Brake fluid.
CAUTION: Never reuse brake fluid that has been drained from the system.
4. Sequence of bleeding air from the brake system: From the wheel cylinder of the left front brake mechanism to the wheel cylinder of the right front brake mechanism, from the wheel cylinder of the left rear brake mechanism to the wheel cylinder of the right rear brake mechanism.
CAUTION: Use only recommended brake fluid.
5. Attach the bleed hose to the bleed nipple on the front passenger side of the brake caliper and place the end of the hose in a clean container of brake fluid.
CAUTION: Brake fluid can damage paintwork. If brake fluid comes into contact with painted surfaces, remove any traces of the fluid immediately and rinse the area with water.
6. Press the brake pedal several times, then hold the pedal down.
7. Loosen the bleed screw to release brake fluid and air from the system. Release the brake pedal, allowing it to return to its original position.
8. Smoothly depress the brake pedal to its full stroke and allow it to return to its initial position. Repeat this operation until the brake fluid drains into the container without any air bubbles. Then, keeping the brake pedal fully depressed, tighten the bleed nipple located on the caliper to 10 Nm and the wheel cylinder nipple to 8 Nm.
CAUTION: During the bleeding procedure, maintain the brake fluid level in the brake system reservoir between the minimum and maximum level marks by adding fresh brake fluid.
9. Add brake fluid to the reservoir to the upper level.
10. Repeat the procedure for each wheel in the sequence shown.
CAUTION: Failure to follow the sequence specified may significantly reduce braking performance.
11. Remove the bleed hose from the fitting and put the protective cap on the fitting.
12. Press the brake pedal and check for any fluid leaks from the system.
13. Remove the supports and lower the vehicle.
14. Test the brake system on the road. When you press the brake pedal, it should be hard and have a short stroke.
