pain; if brake fluid does contact the paint, wash it off
immediately with water.
NOTE: The reservoir on the master cylinder must be at
the MAX (upper) level mark at the start of bleeding pro-
cedure, and checked after bleeding each brake caliper.
Add fluid as required.
1. Make sure the brake fluid level in the reservoir is at
the MAX (upper) level line.

CYIINDER
Have someone slowly pump the brake pedal sever-al times, then apply steady pressure.
Loosen the brake bleed screw to allow air to escapefrom the system. Then tighten the bleed screw se-curely.
Repeat the procedure for each wheel in the sequenceshown below, until atr bubbles no longer appear inthe fluid.
Refill the master cylinder reservoir to the MAX(upperl level line,
