Note: When adding brake fluid to the master cylinder reservoir, use only Delco Supreme 11 or equivalent (DOT-3) fluid from a clean, sealed container.
1. Place a rag under the master cylinder to collect fluid.
2. With the ignition off, press the brake pedal 3-5 times to release the vacuum in the brake booster.
3. If the brake master cylinder was bled outside the vehicle or if the brake pipes were disconnected from the brake master cylinder, perform the following operations:
- a) Set the brake fluid level in the brake cylinder reservoir to the maximum level mark.
- b) Disconnect the front brake pipe from the master cylinder (front nipple).
- c) Drain a small amount of brake fluid from the open nipple of the master brake cylinder (under the action of gravity).
- d) Install the brake pipe in place, tighten the mounting nut.
- d) Ask an assistant to slowly press the brake pedal all the way down and hold the pedal.
- e) Loosen the mounting nut of the same brake pipe to release air from the brake master cylinder.
- g) Tighten the tube nut and ask the assistant to slowly release the brake pedal.
- h) Wait 15 seconds, then repeat steps (c)–(g) until all air has been removed from the master cylinder.
- i) Tighten the front brake pipe mounting nut and perform operations according to points (c) - (g) with the rear brake pipe.
- k) After completing bleeding the master cylinder, securely tighten the brake pipe mounting nuts.
4. Fill the brake master cylinder reservoir more than half full. Maintain the fluid level while bleeding.
Note: Before removing the tank lid, clean the tank surface.
5. Install a closed-end wrench onto the RIGHT REAR brake caliper drain screw.
6. Install a transparent hose onto the drain screw.
7. Submerge the other end of the hose in a transparent container with clean brake fluid.
8. Ask your assistant to slowly press the brake pedal all the way down and hold the pedal.
9. Loosen the drain valve to remove air.
10. Tighten the bleed valve and have an assistant slowly release the brake pedal.
11. Wait 15 seconds and then repeat steps 8-10 until all air is removed.
12. Repeat the bleeding operations in the following sequence:
- LEFT REAR WHEEL;
- RIGHT FRONT WHEEL;
- LEFT FRONT WHEEL.
13. Fill the master cylinder reservoir to the maximum level mark.
14. Slowly press and release the brake pedal.
15. If the pedal is "soft", repeat the bleeding procedure. If the brake pedal remains "soft" after bleeding, then:
- a) Check the brake system for external leaks.
- b) Bleed the system under pressure, you will need special equipment.
16. Turn on the ignition, do not start the engine. Check the status of the brake system indicator. If the indicator remains on, diagnose the system.
