Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety goggles and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts with a socket set.
Carefully slide the caliper off the rotor. Hang it using a bungee cord to avoid stress on the brake line.
Take out the old brake pads from the caliper bracket.
Inspect the brake pads for wear; if they are worn down to the metal or below the manufacturer's minimum thickness, replace them.
Apply brake grease to the back of the new brake pads to reduce noise and ensure smooth operation.
Install the new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotors for any grooves, scoring, or warping.
If the rotors are damaged beyond resurfacing, they should be replaced.
Remove the rotor by unscrewing any retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.

5. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (usually between 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (typically around 80-100 ft-lbs).

6. Final Checks

Pump the brake pedal a few times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
