Bleeding Brake System

This procedure should be followed to ensure adequate bleeding of air and filling of the ABS unit, brake lines and master cylinder with brake fluid.

Remove the reservoir cap and fill the brake reservoir with brake fluid.
CAUTION: If there is any brake fluid on any painted surface, wash it off immediately.

NOTE: When pressure bleeding, do not depress the brake pedal.
Recommended fluid: DOT3 or DOT4
