Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Damaged Components

Sub-steps:
1. Remove the wheel covering the brake assembly.
2. Inspect brake hoses and lines for any signs of cracks or leaks.
3. If damage is found, replace the affected brake line or hose with a new one.
4. Tighten all connections securely and use new washers/gaskets if needed.

3. Bleed the Brake System

Sub-steps:
1. Reconnect the battery.
2. Fill the brake fluid reservoir with the appropriate brake fluid (DOT 3, DOT 4, or as specified by the manufacturer).
3. Starting at the wheel farthest from the master cylinder, attach a brake bleeder kit or a clear tube to the bleeder valve.
4. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
5. Close the valve before your assistant releases the brake pedal. Repeat until no air bubbles are visible in the fluid.
6. Move to the next wheel and repeat the process until all brakes are bled.

4. Test Brake Functionality

Sub-steps:
1. Start the vehicle and pump the brake pedal several times.
2. Check for any warning lights on the dashboard.
3. Conduct a low-speed test drive to ensure the brakes engage properly.
