Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Pads and Rotors

Check the thickness of the brake pads; replace if they are below the manufacturer’s specified minimum thickness (usually around 3 mm).
Inspect the surface of the rotors for grooves or scoring. If damaged, they may need to be resurfaced or replaced.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it without pulling the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are positioned correctly.

5. Reassemble Components

Reattach the caliper over the new pads and secure it with the caliper bolts. Torque bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

6. Final Check

Pump the brake pedal a few times to seat the pads.
Check brake fluid level and add if necessary.
