1. Park the vehicle on a level surface and engage the parking brake.

2. Locate the brake fluid reservoir under the hood of the vehicle and check the fluid level. If it is low, top it up with the recommended brake fluid.

3. Remove the wheel that is closest to the brake caliper you will be bleeding.

4. Attach a clear plastic hose to the bleeder valve on the brake caliper. Place the other end of the hose into a container filled with brake fluid to catch the old fluid.

5. Have a helper sit in the driver's seat and pump the brake pedal several times to build up pressure in the brake system.

6. With the brake pedal held down, open the bleeder valve on the brake caliper using a wrench. Fluid and air bubbles should start to flow through the hose.

7. Close the bleeder valve before the brake pedal is released, then have your helper release the brake pedal.

8. Repeat steps 5-7 until no more air bubbles are visible in the fluid coming out of the bleeder valve.

9. Top up the brake fluid reservoir as needed throughout the bleeding process to prevent air from entering the system.

10. Once all air bubbles are removed and the brake pedal feels firm, replace the wheel and lower the vehicle back to the ground.

11. Repeat the bleeding process for each brake caliper on the vehicle, starting with the caliper farthest from the brake fluid reservoir and working your way closer.

12. Once all calipers have been bled, test the brakes by pressing the pedal to ensure they are functioning properly.

Materials:

- Brake fluid (DOT 3 or 4)
- Bleeder wrench (size varies by vehicle)
- Clear plastic tubing (1/4" inner diameter)
- Open-end wrench
- Funnel
- Clean rags

Safety Precautions:

- Wear eye protection and gloves.
- Do not smoke or have open flames near brake fluid.

Procedure:

1. Check Brake Fluid Level: Ensure that the brake fluid reservoir is full. If necessary, top it up with the correct type of brake fluid.

2. Gather Materials: Collect all necessary materials and prepare the clear tubing by connecting it to the bleeder valve. Submerge the other end of the tubing in a clear container partially filled with brake fluid.

3. Open Bleeder Valve: Start with the wheel furthest from the master cylinder (usually rear passenger-side). Use the bleeder wrench to carefully open the bleeder valve slightly (1/4 to 1/2 turn).

4. Pump and Hold: Ask an assistant to slowly pump the brake pedal several times and then hold it down firmly. While the pedal is held, observe the flow of brake fluid and air bubbles through the tubing.

5. Close Bleeder Valve: Once the flow of fluid becomes steady and free of air bubbles, have the assistant release the brake pedal. Immediately close the bleeder valve before the pedal fully returns.

6. Repeat for Other Wheels: Repeat the process for each of the remaining wheels, moving closer to the master cylinder in sequence (front passenger, rear driver, front driver).

7. Check Fluid Level: After bleeding all four wheels, check the fluid level in the reservoir and top it up if necessary.

8. Test Brakes: Pump the brake pedal several times to restore brake pressure. Test the brakes carefully at low speeds before driving normally.

Tips:

- Use fresh brake fluid and do not reuse old fluid.
- Keep the bleeder wrench clean to prevent contamination.
- If you encounter any air pockets or resistance, continue pumping and bleeding until the problem is resolved.
- If the brake pedal feels spongy after bleeding, it may indicate that there is still air in the system. Repeat the bleeding procedure until the pedal feels firm.
- Allow the brakes to cool down slightly before bleeding.
