Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to ensure safety during work.

2. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line flare tool, brake fluid
Inspect all brake lines and connections for leaks or corrosion.
If any lines are damaged, replace them by using the brake line flare tool to create new lines as necessary.
Refill the brake fluid reservoir after repairs.

3. Replace the Brake Master Cylinder

Tools Required: Socket set, brake fluid, torque wrench
Disconnect the brake lines from the master cylinder using a wrench.
Unbolt the master cylinder from the brake booster.
Remove the old master cylinder and install the new one, ensuring to torque the bolts to manufacturer specifications.
Reconnect the brake lines, ensuring they are secure and leak-free.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing
Begin at the wheel farthest from the master cylinder (usually the passenger rear).
Attach the clear tubing to the bleeder valve and submerge it in brake fluid to prevent air from re-entering.
Open the bleeder valve and pump the brake pedal until no air bubbles are present.
Repeat the process for each wheel, moving closer to the master cylinder (passenger front, driver rear, driver front).
