Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Leaks

Tools Needed: Wrench set, brake line flaring tool, brake fluid.
Check all brake lines and connections for leaks.
If a leak is found, replace the damaged brake line or fitting.
Tighten any loose connections securely.

3. Replace Brake Fluid and Bleed the System

Tools Needed: Brake bleeder kit, catch container, and new brake fluid (DOT 3 or DOT 4).
Remove the reservoir cap and refill with new brake fluid.
Start bleeding from the farthest brake wheel cylinder (usually the right rear).
1. Attach the brake bleeder kit to the bleeder valve on the brake caliper.
2. Open the bleeder valve and have an assistant pump the brake pedal until fluid flows without bubbles.
3. Close the bleeder valve and repeat for each brake caliper in order: right rear, left rear, right front, left front.
Keep an eye on the master cylinder fluid level during this process to prevent air from entering.

4. Inspect and Replace Master Cylinder (if necessary)

Tools Needed: Wrench set, new master cylinder, brake fluid.
If the brake pedal still goes to the floor after bleeding:
1. Disconnect brake lines from the master cylinder.
2. Unbolt the master cylinder from the brake booster.
3. Replace with a new master cylinder.
4. Reconnect brake lines and refill the reservoir with brake fluid.
5. Repeat the bleeding process.
