Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery to prevent any electrical issues.

2. Locate the Leak

Inspect the brake lines, hoses, and connections thoroughly.
If a leak is found, determine the extent of damage to either the lines or components.

3. Replace Damaged Components

Brake Lines/Hoses:
- Use a line wrench to loosen and disconnect the affected brake line/hoses.
- Replace with new brake lines/hose, ensuring proper routing and securing.
Brake Calipers:
- Remove the wheel and inspect the brake caliper.
- If leaking, remove the caliper mounting bolts and disconnect the caliper.
- Replace with a new caliper, ensuring to bleed the brake system afterward.
Master Cylinder:
- Detach the brake lines from the master cylinder using a line wrench.
- Remove the mounting bolts and disconnect the electrical connector if applicable.
- Install the new master cylinder, securing it with bolts and reconnecting the brake lines.

4. Refill and Bleed the Brake System

Fill the brake fluid reservoir with the manufacturer's recommended brake fluid (typically DOT 3 or DOT 4).
Begin bleeding the brakes at the furthest wheel from the master cylinder, usually the right rear, followed by the left rear, right front, and left front.
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.

5. Final Checks

Inspect all connections for leaks.
Ensure the brake fluid level is correct and check the fluid condition.
