Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear gloves and safety glasses for protection.

2. Inspect the Brake Fluid Reservoir

Locate the brake fluid reservoir (usually found near the back of the engine bay).
Remove the cap and check the fluid level against the minimum and maximum marks.
If fluid is low, visually inspect for leaks as described in the diagnostic steps.

3. Check Brake Lines and Hoses

Use a flashlight to inspect the brake lines and hoses for any visible signs of leaks or damage.
If any lines or hoses are damaged, they will need to be replaced.

4. Inspect Brake Calipers and Master Cylinder

Check the brake calipers for fluid accumulation; leaks can occur at the seals.
Inspect the master cylinder for any signs of leakage from the seals or around the mounting area.

5. Repair or Replace Damaged Components

If any leaks are detected:
- For brake lines:
  1. Use a line wrench to disconnect the affected line.
  2. Replace it with a new line, ensuring proper routing and securing.
  3. Use torque specifications per the manufacturer’s guidelines.
- For calipers:
  1. Remove caliper bolts using a socket set.
  2. Replace any faulty seals or the entire caliper as needed.
- For master cylinder:
  1. Disconnect brake lines and electrical connections.
  2. Remove mounting bolts and replace the master cylinder if necessary.

6. Refill Brake Fluid

After repairs, refill the brake fluid reservoir with the appropriate type of brake fluid (e.g., DOT 3, DOT 4).
Bleed the brake system if any brake lines were disconnected.
