Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the front or rear wheel (depending on which brakes are affected).
Jack the vehicle up with a floor jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Check the brake pads for wear; if they are less than 1/8 inch thick, replace them.
Inspect the brake rotors for any scoring or warping; replace if necessary.
Look for any rust or corrosion on calipers and hardware; clean or replace as needed.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.
Apply a thin layer of brake grease on the back of the pads to prevent noise.

5. Reassemble Components

Reattach the caliper over the new brake pads and secure it with the caliper bolts, tightening to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure proper pad seating.
Check brake fluid levels again and top up if necessary.
