Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks for added safety.
Disconnect the negative battery terminal to avoid electrical issues.

2. Remove Wheel

Loosen the lug nuts on the wheel using a socket set.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for uneven wear and thickness.
Check the brake rotors for any grooves, rust, or warping.
Ensure that the brake calipers are not sticking and are functioning properly.

4. Clean Brake Components

Use brake cleaner to spray the brake pads and rotors to remove any dust or debris.
Wipe down the brake components with a lint-free cloth.
Inspect and clean the caliper slides with brake grease if necessary.

5. Replace Brake Pads (if needed)

Remove the caliper bolts using the appropriate socket size.
Carefully slide the caliper off the rotor without stretching the brake line.
Remove the old brake pads and install new ones, ensuring they are seated correctly.
Reinstall the caliper and torque the bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).

6. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the recommended specifications (typically 100-120 ft-lbs).
Reconnect the negative battery terminal.
Test the brakes by applying them in a safe, controlled environment.
