Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety goggles and gloves for protection.

2. Inspect and Clean

Tools Required: Flashlight, brake cleaner
Use a flashlight to closely examine the brake lines, master cylinder, and calipers for any visible leaks.
Clean any residue or dirt from the components using brake cleaner to better identify leaks.

3. Replace Damaged Components

Tools Required: Socket set, wrenches, new brake lines/calipers if needed
If any leaks are found:
- For brake lines:
  1. Remove the damaged line by loosening the fittings using a wrench.
  2. Replace with a new brake line, ensuring proper routing.
  3. Torque fittings to manufacturer specifications (typically around 14-20 ft-lbs).
- For brake calipers:
  1. Remove the caliper from its mounting using a socket set.
  2. Replace with a new caliper, ensuring proper alignment.
  3. Torque the mounting bolts to the manufacturer’s specifications (usually about 25-35 ft-lbs).

4. Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4)
After repairs:
1. Refill the brake fluid reservoir to the correct level.
2. Bleed the brake system to remove any air, starting from the furthest wheel from the master cylinder.

5. Final Inspection

Check all connections and seals for tightness.
Ensure there are no visible leaks or wet spots after the repair.
