Bleed the brake system in the following order only: left rear wheel cylinder, proportioning and bypass valve (Samurai models only), right front wheel caliper, left front wheel caliper.
- Fill the master cylinder reservoir to the MAX line with brake fluid and keep it at least half full throughout the bleeding procedure.
- Remove the bleeder plug cap, then attach a clear vinyl tube to the wheel cylinder bleeder plug. Insert the open end of the hose into a container.
- Have an assistant depress the brake pedal several times. While your helper holds the pedal in the depressed position, loosen the bleeder plug one-third to one-half of a turn (or until brake fluid starts to exit the bleeder valve).
- When the fluid pressure is almost gone, retighten the bleeder plug, THEN have your assistant release the brake pedal. It is very important that the brake pedal stay depressed while the bleeder valve is open, because air will be sucked into the brake system if the pedal is released while the valve is still open.
- If the fluid is level is low, fill the brake master cylinder fluid reservoir with clean DOT 3 fluid.
- Repeat Steps 3 through 5 until all air bubbles are gone from the hydraulic fluid.
- If equipped, install the bleeder plug cap.
- Proceed to the next item to bleed; remember to bleed the vehicle in the proper order. For Samurai models, start with the left rear wheel cylinder, then the P+D valve, then right front caliper, and finally the left front caliper. For all other models, start with the left rear wheel cylinder, then right front caliper, and finally the left front caliper.
- Doublecheck that all bleeder plugs are tightened to 22 inch lbs. (2.5 Nm) after completion.
- After completing the bleeding procedure, apply fluid pressure to the pipe line while checking for leaks.
- Fill the brake fluid reservoir to the specified full level.
- Check brake pedal for a spongy feeling; if any evidence exists, repeat the entire procedure.
MODELS WITH ABS
See Figure 4
1996-98 Sidekick, Tracker and X-90 models equipped with the Anti-Lock Brake System (ABS) require a scan tool to properly bleed the brake system. If you are servicing such a vehicle, please refer to the applicable ABS information located at the end of this information BEFORE you perform any brake procedures.
The ABS systems used on 1990-95 models and Sidekick Sport models should be bled exactly like the non-ABS systems; refer to the previous bleeding procedure.
The 1996-98 Sidekick, Tracker and X-90 models equipped with the ABS system are bled using a special method and tool, refer to the specific ABS information for this procedure.
