WARNING:
^
Brake fluid contains polyglycol ethers and polyglycols. avoid contact with eyes. Wash hands thoroughly after handling. if brake fluid
contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water
and induce vomiting. get medical attention immediately.
CAUTION:
^
Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the
specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system.
^
Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.
NOTE:
^
When any part of the hydraulic system has been disconnected for repair or replacement, air may get into the system and cause spongy brake pedal
action. This requires bleeding of the hydraulic system after it has been properly connected. The hydraulic system can be bled manually or with
pressure bleeding equipment Brake Bleeder.
^
This procedure only needs to be performed if the 4 Wheel Anti-lock Brake System (4WABS) Hydraulic Control Unit (HCU) has been replaced.
^
One conventional pressure bleed cycle consists of advancing the brake pedal to its depressed position, opening the rear disc brake caliper bleeder
screw, allowing fluid to be released into the waste container, closing the rear disc brake caliper bleeder screw and releasing the brake pedal to its
full upright position.
^
Performing the New Generation Star (NGS) program routine drives entrapped air from the otherwise inaccessible lower section of the 4WABS
valve into the upper sections (accessible by bleeding the brakes). Subsequent bleedings remove the air from the system.
^
Add recommended brake fluid as necessary throughout the procedure.
PROCEDURE
1. Connect a clear waste line to the RH rear disc brake caliper bleeder screw and the other end in a container partially filled with recommended brake
fluid.
2. With the RH rear disc brake caliper bleeder screw open, cycle the brake pedal until no more air is seen in the waste line.
3. Close the RH rear disc brake caliper bleeder screw and disconnect the waste line.
4. Repeat steps 1, 2, and 3 for the LH rear disc brake caliper bleeder screw, RH front disc brake caliper bleeder screw, and the LH front disc brake
caliper bleeder screw.
