Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Identify the Leak Source

Sub-steps:
1. Clean the area around suspected leak points with brake cleaner.
2. Fill the brake fluid reservoir to the recommended level.
3. Have an assistant press the brake pedal while you observe potential leak sites for fluid movement.

3. Repair or Replace Affected Components

Sub-steps:
1. Brake Lines:
  - If the brake line is damaged, use a line wrench to remove the affected section.
  - Measure and cut a new section of brake line to length.
  - Flare the ends and install the new line using a line wrench, ensuring all connections are tight.
2. Brake Calipers:
  - If the caliper is leaking, remove the wheel and locate the caliper mounting bolts.
  - Use a socket set to remove these bolts and carefully detach the caliper.
  - Replace the caliper with a new one, ensuring to bleed the brakes afterward.
3. Master Cylinder:
  - If the master cylinder is leaking, disconnect the brake lines and remove the mounting bolts.
  - Replace it with a new unit, ensuring proper torque on the mounting bolts.

4. Bleed the Brake System

Sub-steps:
1. Reconnect brake lines and ensure they are secure.
2. Refill the brake fluid reservoir with the appropriate brake fluid (DOT 3 or DOT 4).
3. Begin bleeding the brakes starting from the furthest wheel from the master cylinder to the closest, typically: right rear, left rear, right front, left front.
4. Use a brake bleeder kit or have an assistant pump the brake pedal to expel air from the system.
