Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" lines.
3. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual) to reach the correct level.
4. Replace the cap securely.

3. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear).
2. Attach a clear tube to the bleeder valve on the brake caliper and place the other end into a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to allow fluid and air to escape, then close it before your assistant releases the pedal.
5. Repeat this process until no air bubbles appear in the fluid, moving to the left rear, right front, and then left front wheels.

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake caliper and pads.
2. Check the brake pads for thickness; replace if worn below specification (usually 3mm).
3. Inspect the rotors for scoring or warping; replace if necessary.
4. Check the brake calipers for proper operation and any signs of leakage.

5. Test the Brake System

Sub-steps:
1. After completing the bleeding process, press the brake pedal to ensure it feels firm.
2. Conduct a road test to verify that the brakes respond correctly and the pedal does not feel soft.

Tools Required:
