Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Identify the Leak Source

Sub-steps:
- Clean the brake area thoroughly to remove any old fluid and dirt.
- Use a flashlight to inspect all components of the brake system more clearly.
- If the leak is from the brake lines or hoses, proceed to replace as necessary.

  2. Install the new brake line, ensuring proper routing and securing it with clamps.
  3. Torque the fittings to the manufacturer’s specifications.
- If the brake caliper or wheel cylinder is leaking:
  1. Remove the wheel and caliper or drum assembly.
  2. Replace the leaking caliper or cylinder with a new one.
  3. Bleed the brake system to remove air.
- If the master cylinder is leaking:
  1. Disconnect the brake lines from the master cylinder.
  2. Unbolt the master cylinder from the brake booster.
  3. Install the new master cylinder and reconnect lines.

4. Refill and Bleed the Brake System

Sub-steps:
- Refill the brake fluid reservoir with the specified brake fluid (DOT 3 or DOT 4).
- Bleed the brake system using the correct sequence (usually starting from the furthest wheel from the master cylinder).
- Check for any remaining leaks around the repaired areas.
