Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Engage the parking brake for safety.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rag
Check the brake fluid level; if low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
If the fluid is dark or contaminated, proceed to replace it.
Sub-steps:
1. Locate the brake fluid reservoir and remove the cap.
2. Use a clean funnel to add new brake fluid to the reservoir.
3. Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or tubing, container for old fluid, wrench for bleeder valves
Safety Warning: Wear safety glasses and gloves to protect against brake fluid.
Sub-steps:
1. Begin with the brake caliper farthest from the master cylinder (typically the rear passenger side).
2. Attach the bleeder kit to the bleeder valve and loosen the valve with a wrench.
3. Have an assistant press the brake pedal slowly and hold it down.
4. Open the bleeder valve to release fluid until no air bubbles are observed, then close the valve.
5. Repeat this process on each brake caliper in the following order: rear passenger, rear driver, front passenger, front driver.
6. Continuously check the brake fluid reservoir and top off as necessary.

4. Inspect Brake Components

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the wheel to access the brake components.
2. Visually inspect brake pads for wear; replace if they are below the manufacturer's minimum thickness.
3. Check the brake rotors for any abnormalities or warping. Replace if necessary.
4. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
