Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and safety equipment (gloves, goggles).
Place wheel chocks behind the rear wheels.

2. Locate the Leak

Use a flashlight to inspect the brake lines, calipers, and master cylinder.
Clean the area around the suspected leak with brake cleaner to identify the source.

3. Repair the Leak

a. If the leak is in the brake lines:

Tools Required: Wrench set, brake line tool, flare nut wrench
Cut the damaged section of the brake line with a pipe cutter.
Attach a new brake line using a flare fitting, ensuring it is secure and leak-free.
Bleed the brake system to remove air from the lines.

b. If the leak is from the brake caliper:

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake caliper.
Unbolt the caliper and inspect the seals; replace if damaged.
Reinstall the caliper and torque bolts to manufacturer specifications.

c. If the leak is from the master cylinder:

Tools Required: Socket set, torque wrench
Disconnect the brake lines from the master cylinder.
Remove the master cylinder from the brake booster.
Install a new master cylinder and reconnect the brake lines, ensuring a tight fit.

4. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the recommended brake fluid type (DOT 3 or DOT 4).
Bleed the brakes at each wheel, starting with the wheel furthest from the master cylinder, to ensure all air is removed from the system.
