Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Wear safety goggles and gloves.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake cleaner, rags.
Inspect all brake lines and connections for leaks.
- If a leak is found, tighten loose connections or replace damaged lines.
- Clean any spilled brake fluid with brake cleaner and rags.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old brake fluid.
Fill the master cylinder with new brake fluid.
Start bleeding the brakes:
1. Attach the clear tubing to the bleeder valve on the furthest brake caliper (usually the passenger rear).
2. Have an assistant press the brake pedal several times, then hold it down.
3. Open the bleeder valve to allow fluid and air to escape, then close it before your assistant releases the pedal.
4. Repeat until no air bubbles are present in the fluid.
5. Move to the next calipers in this order: passenger front, driver rear, driver front.

4. Replace the Master Cylinder (if necessary)

Tools Required: Socket set, wrench set, brake fluid, torque wrench.
If bleeding does not resolve the issue, replace the master cylinder:
1. Disconnect the brake lines from the master cylinder.
2. Unbolt the master cylinder from the brake booster.
3. Install the new master cylinder and torque to manufacturer specifications.
4. Reattach the brake lines and ensure they are secure.
5. Refill the master cylinder with brake fluid and bleed the system again.
