Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the recommended brake fluid (DOT 4 or as specified in the owner’s manual).
3. Replace the reservoir cap securely after adding fluid.

3. Inspect and Repair Brake Leaks

Sub-steps:
1. Visually inspect brake lines, hoses, and connections for signs of leaks.
2. Tighten any loose fittings or replace damaged brake lines or hoses.
3. If leaks are found, replace the affected parts with OEM or equivalent components.

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel furthest from the master cylinder (usually the right rear).
2. Attach a clear plastic hose to the bleeder valve and submerge the other end in a container with brake fluid.
3. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid; close the valve before the pedal is released.
4. Repeat this process for each wheel in the order: right rear, left rear, right front, and left front.
5. Ensure the brake fluid reservoir is always kept filled during the bleeding process.

5. Inspect and Replace Master Cylinder (if necessary)

Sub-steps:
1. If the pedal still goes to the floor after bleeding, the master cylinder may be faulty.
2. Disconnect the brake lines from the master cylinder and remove it from the brake booster.
3. Install the new master cylinder and torque the mounting bolts to the manufacturer’s specifications.
4. Reconnect the brake lines and bleed the brake system again.
