Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent vehicle movement.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Inspect the fluid level; if low, add manufacturer-recommended brake fluid (usually DOT 4).
- Check for any leaks around the reservoir and cap.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench.
Sub-steps:
- Start with the brake that is farthest from the master cylinder (typically the right rear).
- Attach the bleeder kit to the brake caliper.
- Have an assistant press the brake pedal several times and hold it down.
- Open the bleeder valve to let air and fluid escape; close it once fluid flows without bubbles.
- Repeat for each brake in the following order: right rear, left rear, right front, left front.

4. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake assembly.
- Check the brake pads for wear; replace if they are below the manufacturer’s specifications.
- Inspect the brake rotors for scoring or warping; replace if necessary.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and tighten the lug nuts to the manufacturer’s torque specifications.
- Lower the vehicle and start the engine.
- Gradually press the brake pedal to ensure it feels firm.
