Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; it should be between the minimum and maximum lines.
3. If low, refill with the manufacturer's recommended brake fluid (DOT 4).
4. Replace the cap securely.

3. Inspect and Replace Leaking Components

Sub-steps:
1. Visually inspect brake lines for any signs of wear or leaking fluid.
2. If leaks are found in the brake lines, use a line wrench to disconnect and replace the affected section of the line.
3. Check the calipers and replace any that are leaking using a socket set.
4. If the master cylinder is leaking, remove it by disconnecting the brake lines and unbolting it from the brake booster.

4. Bleed the Brake Lines

Sub-steps:
1. Start at the wheel farthest from the master cylinder (passenger side rear).
2. Attach a clear plastic tube to the bleeder valve and submerge it in a container with brake fluid.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to allow air and fluid to escape, then close it before the pedal is released.
5. Repeat the process on the other wheels in the order: passenger rear, driver rear, passenger front, driver front.

5. Test the Brakes

Sub-steps:
1. Start the engine and pump the brake pedal to build pressure.
2. Check for firmness in the pedal.
3. Test drive the vehicle at low speeds to ensure brakes are functioning properly.
