Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Raise Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the leak is suspected.
Secure with jack stands for safety.

3. Identify and Fix Brake Line Leaks

Inspect Brake Lines:
- Use a flashlight to closely examine all brake lines for any visible damage.
Replace Damaged Lines:
- If a leak is found, use a line wrench to disconnect the damaged brake line.
- Replace with a new line of the same diameter and length, ensuring proper positioning and routing.
- Torque fittings to manufacturer specifications (usually around 15-20 ft-lbs).

4. Repair or Replace Brake Calipers

Inspect Calipers:
- Check the calipers for any signs of fluid leakage.
Replace Calipers (if necessary):
- Remove the wheel and caliper bolts using a socket set.
- Disconnect the brake line from the caliper, ensuring to catch any residual fluid.
- Install the new caliper, reconnect the brake line, and torque to specifications.

5. Repair or Replace Master Cylinder

Inspect Master Cylinder:
- Look for leaks around the master cylinder.
Replace Master Cylinder (if necessary):
- Disconnect the brake lines using a line wrench and remove any electrical connectors.
- Unbolt and remove the master cylinder from the brake booster.
- Install the new master cylinder and reconnect lines, torque to specifications (typically 15-20 ft-lbs).

6. Refill and Bleed Brake System

Refill the brake fluid reservoir with the recommended fluid (DOT 3 or DOT 4).
Bleed the brake system to remove any air using a brake bleeder kit, starting from the furthest wheel and working towards the closest.
