Solution

1. Preparation

Tools Required: Socket set, wrenches, brake fluid, clean rags
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before proceeding.

2. Locate the Leak

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Inspect visually for cracks or leaks, and check the fluid level.
- If the reservoir is low, use a clean rag to wipe around it and check for leaks.

3. Repair or Replace Damaged Components

Sub-steps:
- If the reservoir is cracked, replace it with a new one.
  - Disconnect the brake fluid lines and remove the old reservoir.
  - Install the new reservoir and connect the lines securely.
  - Torque specifications may vary; refer to the service manual.
- For leaking brake lines or hoses, replace the affected section.
  - Use a line wrench to disconnect the damaged line.
  - Cut a new line to the required length and flare the ends.
  - Connect it securely and check for proper alignment.

4. Bleed the Brake System

Sub-steps:
- Fill the brake fluid reservoir with new DOT 3 or DOT 4 brake fluid.
- Start bleeding the brakes from the furthest wheel from the master cylinder (usually the rear passenger side).
- Use a helper or a brake bleeder tool to press the brake pedal while you open the bleeder valve on each caliper.
- Close the valve before the pedal is released to avoid air entering the system.
- Repeat until clear fluid with no bubbles comes out, then move to the next wheel.

5. Final Inspection

Sub-steps:
- Check all connections for leaks after the repair.
- Ensure the brake fluid level is at the correct mark in the reservoir.
- Test the brake pedal feel; it should feel firm.
