Manual Bleeding

Tools Required
J28434 Wheel Cylinder Bleeder Wrench

1. Apply the brakes several times with the ignition OFF in order to relieve the brake vacuum reserve.
2. Fill the master cylinder reservoirs with DOT 3 motor vehicle brake fluid.
3. Maintain the fluid level during bleeding.
4. If the master cylinder has air in the bore, bleed the master cylinder using the following procedure:
4.1. Disconnect the forward brake pipe connector at the master cylinder.
4.2. Allow the brake fluid to flow from the connector port.
4.3. Connect the brake pipe connector. Do not tighten the brake pipe connector.
4.4. Slowly apply the brake pedal and allow the air to bleed from the loose connector.
4.5. Tighten the connector before releasing the brake pedal.
4.6. Wait 15 seconds.
4.7. Repeat this sequence, including the 15 second wait, until all air is purged from the master cylinder bore.
4.8. Repeat this procedure for the rear brake pipe after you purge all the air from the forward pipe connection.
5. If the brake pressure modulator valve of the antilock brake system is replaced or if you suspect that air is trapped inside, bleed the brake pressure modulator valve next. Refer to Brake Pressure Modulator Valve Replacement in Antilock Brake System.
6. Bleed each wheel cylinder in the following sequence:
6.1. Right rear wheel cylinder.
6.2. Left rear wheel cylinder.
6.3. Right front wheel caliper.
6.4. Left front wheel caliper.
7. Attach J28434 on the wheel cylinder or caliper bleeder valve.
8. Immerse the opposite end of the hose into a container partially filled with clean brake fluid.
9. Slowly apply the brake pedal one time and hold.
10. Loosen the bleeder valve in order to purge the air from the wheel cylinder or caliper.
11. Tighten the bleeder valve and slowly release the brake pedal.
12. Wait 15 seconds.

NOTICE: Refer to Fastener Notice in Cautions and Notices.

13. Repeat this sequence, including the 15-second wait, until all air is purged from the wheel cylinder or caliper.

Tighten:
Tighten the bleeder valve to 7 Nm (62 inch lbs.).

14. Repeat steps 7 through 13 at each wheel until the brake system is bled.
15. Check the brake pedal for sponginess, and check the brake warning lamp for an indication of unbalanced pressure. Repeat the bleeding procedure in order to correct either of these conditions.
