Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety glasses and gloves.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Brake Lines (if damaged)

Tools Required: Wrench set, brake line flaring tool, brake line cutter, DOT 3 brake fluid.
Inspect the brake lines thoroughly.
If damaged, cut the old line using a brake line cutter.
Flare the ends of the new brake line using the flaring tool.
Route the new line along the original path, securing it with brackets.
Connect the new line to the master cylinder and calipers, ensuring tight fittings.

3. Replace Brake Caliper (if leaking)

Tools Required: Socket set, torque wrench, brake cleaner, new brake caliper, new brake pads (optional).
Remove the wheel to access the brake caliper.
Disconnect the brake line from the caliper using a wrench.
Remove the caliper mounting bolts and slide the caliper off the rotor.
Install the new caliper, ensuring it is aligned properly and secured with mounting bolts.
Reconnect the brake line and tighten it to the manufacturer's specifications.

4. Replace Master Cylinder (if leaking)

Tools Required: Socket set, brake fluid, torque wrench.
Disconnect the brake lines from the master cylinder, noting their positions.
Remove the mounting bolts securing the master cylinder to the brake booster.
Install the new master cylinder and torque the bolts to specifications.
Reconnect the brake lines, ensuring they are secure and free of leaks.

5. Bleed the Brake System

Tools Required: Brake bleeder kit, assistant (optional).
Start at the wheel farthest from the master cylinder (usually the passenger rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve on the brake caliper, allowing fluid to escape until no air bubbles are visible.
Close the bleeder valve and repeat the process on each wheel in the proper order (passenger rear, driver rear, passenger front, driver front).
Check fluid levels in the reservoir and top off as necessary.
