Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues while working on the brake system.

2. Locate the Leak

Inspect Brake Lines and Hoses
- Use a flashlight to examine all brake lines and hoses for cracks or dampness.
- If any are damaged, mark the specific areas for replacement.
Check Brake Calipers and Wheel Cylinders
- Remove the wheels using a socket set.
- Inspect the brake calipers for fluid leaks around the seals.
- Check the wheel cylinders for any signs of dripping brake fluid.

3. Repair or Replace Affected Components

For Brake Lines and Hoses
- Use a line wrench to disconnect the damaged brake line or hose.
- Install the new brake line or hose, ensuring all fittings are tight (torque to manufacturer specifications).
For Brake Calipers
- Remove the caliper bolts with a socket wrench.
- Replace the caliper if leaking, or replace seals if applicable.
- Reattach the caliper and torque bolts to specification.
For Master Cylinder
- Disconnect brake lines from the master cylinder.
- Remove mounting bolts and lift off the master cylinder.
- Replace with a new master cylinder if leaking and reconnect lines.

4. Refill Brake Fluid

Fill the brake fluid reservoir with the recommended type of brake fluid (DOT 3 or DOT 4, refer to owner’s manual).
Bleed the brake system to remove air bubbles, starting from the furthest wheel from the master cylinder.
