Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the brake fluid reservoir cap.
2. If fluid is low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
3. Replace the cap securely after refilling.

3. Inspect and Repair Leaks

Sub-steps:
1. Visually inspect brake lines and hoses for cracks or corrosion.
2. If a leak is found, replace the damaged hose or line.
3. Tighten any loose connections and ensure all fittings are secure.

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel furthest from the master cylinder (usually the rear passenger side).
2. Attach a clear hose to the bleeder valve and submerge the other end in a container filled with brake fluid.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid; close the valve once the pedal is at the bottom.
5. Repeat this process for all wheels in the proper order (rear passenger, rear driver, front passenger, front driver).
6. Check the fluid level in the master cylinder frequently during bleeding and refill as necessary.

5. Final Inspection

Sub-steps:
1. Start the vehicle and pump the brake pedal to ensure it feels firm.
2. Test drive the vehicle to confirm the brakes are functioning properly.
3. Check for any leaks after the test drive.
