Acclaim L4-153 2.5L SOHC Flex Fuel (1994)
Fig 49 Modulator Assembly Primary Accumulator Circuit Bleed
a. Connect clear bleed tube to primary accumulator bleeder screw, then submerge other end of tube in a clear container of clean brake fluid.
b. Have an assistant pump brake pedal several times, then maintain a constant, relatively heavy pressure on pedal.
c. Using DRB scan tool, select "Bleed ABS Hydraulic Unit" mode.
d. While in this mode, select "Primary Circuit Valves," then open modulator assembly primary sump circuit bleeder screw at least one full turn.
e. Allow fluid to flow continuously until it appears to be free of air bubbles. If brake pedal bottoms out before bubbles cease, repeat accumulator
circuit bleed procedure.
f.
Close bleeder screw only snugly (without final tightening), then release brake pedal.
g. Disconnect scan tool, then pump brake pedal several times and maintain a constant heavy force on pedal.
h. Open primary accumulator circuit bleed screw, then continue to bleed circuit until a clear, bubble-free flow of fluid can be maintained.
i.
Close bleeder screw, then release brake pedal and torque bleeder screw to 80 in. lbs.
11. Bleed modulator assembly secondary sump circuit as follows:
Fig 50 Modulator Assembly Secondary Sump Circuit Bleed
a. Connect clear bleed tube to secondary sump bleeder screw, then submerge other end of tube in a clear container of clean brake fluid.
b. Have an assistant pump brake pedal several times, then maintain a constant, relatively heavy pressure on pedal.
c. Open modulator assembly secondary sump circuit bleeder screw at least one full turn; then, using DRB scan tool, select "Bleed ABS Hydraulic
Unit" mode.
d. While in this mode, select "Secondary Circuit" continuously until fluid flows freely through bleed tube without air bubbles.
e. If brake pedal bottoms out before an air free flow of fluid can be maintained, repeat sump circuit bleed procedure.
f.
When sump circuit has been fully bled, torque bleeder screw to 80 in. lbs.
