Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat 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 master cylinder.
2. Check the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4).
3. Close the master cylinder cap securely after refilling.

3. Inspect and Replace Damaged Components

Sub-steps:
1. Visually inspect brake lines for cracks or leaks and replace any damaged sections.
2. Check brake pads and rotors; if worn, replace them according to manufacturer specifications.
3. If the brake calipers are leaking, they will need to be replaced.

4. Bleed the Brake System

Sub-steps:
1. Locate the brake bleeder valves on each brake caliper.
2. Attach a clear hose to the bleeder valve and place the other end in a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid, then close it.
5. Repeat for each wheel until no air bubbles are visible in the fluid.
6. Recheck the brake fluid level in the master cylinder and top off if necessary.
