Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake fluid.
Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake lines for cracks or corrosion; replace any damaged lines.
3. Check brake calipers for leaks; replace calipers if necessary.
4. Inspect the master cylinder and replace it if leaks are found.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container to catch old fluid.
Sub-steps:
1. Fill the brake fluid reservoir with new brake fluid (DOT 3 or DOT 4 as specified).
2. Begin bleeding at the farthest wheel from the master cylinder (usually the passenger rear).
3. Connect the clear tubing to the bleeder screw and place the other end in the container.
4. Open the bleeder screw and have an assistant press the brake pedal several times; close the screw while the pedal is pressed.
5. Repeat until no air bubbles appear in the fluid.
6. Move to the next wheel and repeat the process until all brakes are bled.

4. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reattach the wheel and torque lug nuts to the manufacturer's specifications.
2. Reconnect the battery.
3. Start the vehicle and pump the brake pedal to ensure it feels firm.
