Solution

1. Preparation

Tools Required: Socket set, brake line wrench, brake fluid, multimeter, cleaning cloths.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines for leaks or corrosion.
2. Replace any damaged brake lines using a line wrench; ensure proper fitting and torque.
3. Bleed the brake lines to remove any air bubbles.

3. Replace Brake Pads and Rotors (if needed)

Sub-steps:
1. Remove the wheel and tire assembly using a lug wrench.
2. Unbolt the caliper and suspend it using a hanger to avoid stress on the brake line.
3. Remove the old brake pads and inspect the rotor for grooves or warping.
4. If necessary, replace the rotors; ensure they are torqued to the manufacturer’s specifications.
5. Install new brake pads and reassemble the caliper.

4. Check and Refill Brake Fluid

Sub-steps:
1. If the brake fluid level is low, top up with the recommended brake fluid type (DOT 3 or DOT 4).
2. Inspect the master cylinder for any leaks or damage; replace if necessary.

5. Test the Brake System

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and pump the brake pedal to build pressure.
3. Conduct a test drive to ensure the brake pedal feels firm and responsive.
