Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure it is in gear or in "Park" mode.
Allow the engine to cool down before starting.

2. Identify and Replace Leaking Components

Brake Lines:
- Locate the leaking section of the brake line.
- Use a wrench to disconnect the line from the fitting.
- Replace with a new brake line, ensuring it matches specifications.
- Torque the fittings to the manufacturer’s specifications.
Brake Calipers:
- Remove the wheel to access the brake caliper.
- Using a socket, remove the caliper bolts and detach the caliper from the bracket.
- Inspect the caliper seals for damage; replace if necessary.
- Reinstall the caliper, ensuring it is properly positioned.
Master Cylinder:
- Locate the master cylinder and visually inspect for leaks.
- Disconnect brake lines from the master cylinder using a wrench.
- Remove the mounting bolts and lift the master cylinder off.
- Install the new master cylinder and reconnect the brake lines, torquing to specification.

3. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3, DOT 4, or as specified).
Bleed the brake lines using a brake bleeder kit or by the two-person method to remove air from the system.
Ensure that the brake pedal feels firm and responsive after bleeding.
