Solution

1. Preparation

Tools Required: Brake fluid, gloves, safety glasses, socket set, wrench set.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines from the master cylinder to the calipers for any signs of leakage or damage.
2. If leaks are found, replace the damaged section of the brake line using appropriate fittings and connectors.
3. Tighten all connections to the manufacturer's torque specifications.

3. Bleed the Brake System

Sub-steps:
1. Fill the master cylinder reservoir with fresh brake fluid.
2. Starting from the wheel farthest from the master cylinder (usually the right rear), use a brake bleeder kit to open the bleeder valve.
3. Have an assistant pump the brake pedal several times, then hold it down while you close the bleeder valve.
4. Repeat this process until no air bubbles appear in the fluid.
5. Move to the next wheel (left rear, right front, left front), repeating the bleeding process.
6. Ensure the master cylinder does not run low on brake fluid during bleeding.

4. Replace Brake Components (if necessary)

Sub-steps:
1. If brake pads or rotors are worn, remove the wheel and tire.
2. Remove the caliper and bracket, and replace the pads and/or rotors as needed.
3. Reassemble the caliper and bracket, ensuring all bolts are tightened to the specified torque.

5. Final Inspection

Sub-steps:
1. Inspect the brake pedal feel and travel again after completing repairs.
2. Test the brakes at low speed in a safe area to confirm proper operation.
