Solution

1. Preparation

Tools Required: Brake bleeder kit, wrench (usually 10mm), clear plastic tubing, brake fluid (DOT 3 or DOT 4 as specified).
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Wear safety goggles and gloves to protect against brake fluid.

2. Locate Brake Bleeder Screws

Identify the brake bleeder screws on each wheel (typically located on the brake caliper).
Clean the area around each bleeder screw to prevent contamination.

3. Bleed the Brakes

Start with the right rear wheel:
1. Attach the clear plastic tubing to the bleeder screw and place the other end in a container to catch fluid.
2. Have your assistant pump the brake pedal several times and hold it down.
3. Open the bleeder screw slightly with the wrench to allow air and old fluid to escape until a steady stream of fluid is seen.
4. Close the bleeder screw before your assistant releases the brake pedal.
5. Repeat the process until no air bubbles are visible in the fluid.
Continue with the left rear wheel, right front wheel, and finally the left front wheel following the same procedure.

4. Check Fluid Level

After bleeding all four wheels, check the brake fluid reservoir and top off as necessary to the recommended level.

5. Final Checks

Inspect for any leaks around the bleeder screws and brake lines.
Ensure all bleeder screws are tightened to the manufacturer's specifications.
