Brake Bleeding: Service and Repair
Master Cylinder Priming - In-Vehicle or Bench
WARNING: Use of any other than approved DOT 3 brake fluid will cause permanent damage to brake components and will render the brakes
inoperative.
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 10 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 installation of new components, air can enter 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.
NOTE: When a new brake master cylinder has been installed or the system has been emptied, or partially emptied, it should be primed to prevent air
from entering the system.
1. For in-vehicle priming, disconnect the brake lines.
2. For bench priming, mount the brake master cylinder in a vise.
3. Install short brake tubes with the ends submerged in the brake master cylinder reservoir, and fill the brake master cylinder reservoir with High
