Solution

1. Preparation

Tools Required: Wrench set, brake fluid, clean rags, jack and jack stands, safety goggles, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before beginning repairs. Wear safety goggles and gloves to protect against brake fluid.

2. Locate the Leak

Inspect the brake lines, calipers, master cylinder, and wheel cylinders for any visible leaks.
Clean any areas with brake cleaner to better identify the source of the leak.

3. Repair or Replace Affected Parts

Brake Lines:
1. If a brake line is leaking, use a wrench to disconnect the line at the affected section.
2. Cut the damaged section of the line and replace it with a new piece of brake line.
3. Flare the ends of the new line and reattach securely.
Brake Calipers:
1. If the caliper is leaking, remove the wheel and use a wrench to unbolt the caliper from the bracket.
2. Replace the caliper with a new unit, ensuring to properly install new seals and bleed the brakes afterward.
Master Cylinder:
1. If the master cylinder is leaking, disconnect the brake lines from the master cylinder and remove the mounting bolts.
2. Replace the master cylinder with a new one, and reconnect all lines securely.

4. Refill and Bleed Brake System

Fill the brake fluid reservoir with the appropriate type of brake fluid (consult the owner's manual for specifications).
Bleed the brake system by having an assistant press the brake pedal while you open and close the bleeder screws on each brake caliper, starting from the furthest from the master cylinder.
