Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Safety goggles and gloves should be worn.

2. Check and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Clean the reservoir cap before opening to prevent contamination.
3. Check the fluid level against the minimum and maximum marks.
4. If low, add the appropriate brake fluid type (DOT 3 or DOT 4 as specified by manufacturer).

3. Inspect Brake Lines and Components

Sub-steps:
1. Visually inspect all brake lines and hoses for cracks, corrosion, or leaks.
2. Check brake calipers and wheel cylinders for signs of leakage.
3. Replace any damaged lines or components found.

4. Bleed the Brakes

Sub-steps:
1. Start from the wheel farthest from the master cylinder (usually the right rear).
2. Connect a clear tube 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 let air and old fluid escape.
4. Close the valve before the pedal is released and repeat until no air bubbles are present.
5. Move to the next wheel and repeat the process.

5. Replace Worn Brake Components

Sub-steps:
1. If brake pads are worn below the manufacturer's specifications, replace them.
2. Inspect the rotors for scoring; replace if necessary.
3. Use a torque wrench to ensure proper torque values when reassembling components.
