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.
CAUTION: 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 new installation, air may get into the system and cause spongy
brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or
with pressure bleeding equipment.
1. Support the brake master cylinder body in a vise and fill the brake master cylinder reservoir with specified brake fluid.

2. Install short brake tubes with the ends submerged in the brake master cylinder reservoir.
3. Slowly depress the primary piston until clear fluid flows from both brake tubes, without air bubbles.
4. Remove the short brake tubes.
