Brake Fluid Line Bleeding Test

When repairing the brake fluid line or encountering spongy brake pedal movement, follow these steps for bleeding the brake fluid line:

1. Work requires two people. Start the engine and keep it idling during the procedure.
2. Fill the reserve tank with brake fluid, maintaining it at least half full.
3. Attach a vinyl tube to the bleeder screw on the wheel cylinder, directing the other end into a container filled with brake fluid.
4. One person should depress the brake pedal several times, then hold it depressed while the other releases the bleeder screw. Tighten the screw before the fluid flow stops.
5. Repeat until air bubbles are absent in the fluid, ensuring the reserve tank is at the correct level.

Notes:

• If the pedal feels soft, use a vacuum pump to remove air from the master cylinder, lines, and wheel cylinders.
• Maintain a sufficient brake fluid level in the reserve tank at all times.
• Only use the specified brand of brake fluid, avoiding any mixing of fluids.
• Begin bleeding the brake fluid from the wheel cylinder on the right side, farthest from the master cylinder.
