Bleeding the hydraulic brake system on 1991-99 models without ABS is performed using the following procedure. On 1994-96 models with ABS, you also may also use the following procedure. However, a scan tool is absolutely necessary to bleed the brake hydraulic system on 1997-99 models equipped with an Anti-lock Brake System (ABS). If your 1997-99 vehicle is equipped with ABS, be sure to refer to the ABS bleeding procedures in this section before performing any work on your vehicle's brake hydraulic system.
- Clean the area around the master cylinder filler cap and remove the cap.
- Fill the reservoir with clean brake fluid and install the cap.
- If the master cylinder is known or suspected to have air in the bore, it must be bled before any of the wheel cylinders or calipers. To bleed the master cylinder, position a shop towel under the rear master cylinder outlet fitting and loosen the fitting approximately 3 / 4 turn. Have an assistant depress the brake pedal slowly through its full range of travel. Close the outlet fitting and let the pedal return slowly to the fully released position. Wait 5 seconds, then repeat the operation until all air bubbles disappear.
- Repeat the master cylinder bleeding procedure at the front master cylinder outlet fitting.
- Position a correct size box-end wrench or flare nut wrench on the bleeder screw at the right rear wheel.
Always bleed the longest line first, which is the right rear line.
- Attach one end of a clear ose to the brake bleeder screw and the other end into a container half full of clean brake fluid.
- Loosen the bleeder screw while an assistant apply the brake pedal slowly through its entire travel.
- Close the brake bleeder and then have the assistant release the brake pedal.
- Continue bleeding the right rear wheel until the fluid is free of air bubbles.
DO NOT allow the master cylinder to run out of brake fluid. Only use fresh DOT 3 or equivalent brake fluid from a closed container.
- Repeat the procedure on the left front wheel, then the left rear and finally the right front wheel.
- Throughout the brake bleeding process, continually check the brake master cylinder and top off the fluid as required.
- If the brake pedal is spongy, repeat the brake bleeding procedure.
