Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake and wear safety glasses and gloves.

2. Locate the Leak

Tools Required: Flashlight
Inspect the brake fluid reservoir to confirm fluid level is low.
Trace brake lines from the master cylinder to wheels, looking for wet spots or corrosion.

3. Replace Damaged Components

A. Brake Lines

Tools Required: Wrench set, brake line tool
Disconnect the brake line at both ends using a wrench.
Remove the damaged section of brake line.
Measure and cut a new brake line to match the old one.
Install the new brake line, ensuring all fittings are tight but not over-torqued.

B. Brake Hoses

Tools Required: Wrench set, pliers
Use pliers to disconnect the brake hose at the caliper and the brake line.
Replace with a new brake hose and secure it properly.

C. Calipers and Wheel Cylinders

Tools Required: Socket set, brake cleaner
If a caliper is leaking, remove it from the bracket using a socket set.
Clean the mounting surface and install a new caliper.
If a wheel cylinder is leaking, remove it from the brake backing plate and replace it.

4. Refill and Bleed the Brake System

Tools Required: Brake fluid, brake bleeder kit
Refill the brake fluid reservoir with the manufacturer-recommended brake fluid.
Bleed the brakes by starting at the wheel farthest from the master cylinder, ensuring no air is trapped in the lines.
