The RABS II master cylinder and hydraulic control unit must be bled using anti-lock brake adapter tool No. T90P-50-ALA and jumper tool No. T93T-50-ALA, or equivalents. If this procedure is not followed, air will be trapped in the hydraulic control unit and will contribute to improper brake pedal feel.

Bleed system as follows:

• Place bleed/harness switch on bleed adapter tool to bleed position.
• Turn ignition switch to On position. At this point, the red OFF indicator should turn on.
• Push motor button on the adapter down. This starts the pump moto...

When the brakes are applied, fluid is forced from the master cylinder outlet ports to the Hydraulic Control Unit (HCU) inlet ports. This pressure is transmitted through three normally open solenoid valves contained inside the HCU, then through the outlet ports of ...
