Ensure master cylinder reservoir is full of brake fluid. If master cylinder was rebuilt or reservoir ran dry, bleed master cylinder first. Connect vinyl tube to caliper bleed screw and insert other end of tube in a clear container 1/4 full of brake fluid.
Slowly pump brake pedal several times. While depressing brake pedal, loosen bleed screw until fluid starts to flow out, and then close bleed screw. Repeat operation until no bubbles are present in fluid. Tighten bleed screw to 96 INCH lbs. (11 N.m). See BRAKELINE BLEEDING SEQUENCE table.
Remove brake fluid reservoir cap. Ensure master cylinder reservoir is full of brake fluid. Install ABS Actuator Pump (SST 09992-00242, 09992-00350) on top of brake fluid reservoir. See Fig 1. Connect vinyl tube to brake actuator bleed screw and insert other end of tube in a clear container 1/4 full of brake fluid. See Fig 2. Using hand pump, apply 14.2 psi (1.0 kg/cm² ).
Loosen bleed screw on brake actuator. Bleed air from brake actuator. Tighten bleed screw to 73 INCH lbs. (8.3 N.m). Fill reservoir. Remove hand pump. Clear diagnostic trouble codes. See CLEARING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING.

NOTE: If master cylinder has been disassembled, is new or reservoir becomes empty, bleed master cylinder before bleeding wheels.

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
