Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the opposite wheels.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the wheel is still on the ground.
Lift 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 caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord or similar to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for thickness; replace if worn below manufacturer specifications (usually 3mm or less).
Install new brake pads into the caliper bracket ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any grooves or excessive wear.
If the rotors are below minimum thickness or damaged, remove the caliper bracket using a socket set and take off the rotor.
Install new rotors, ensuring they are properly torqued according to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble and Check Brake System

Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
Replace the wheel, hand-tighten the lug nuts, and lower the vehicle back to the ground.
Torque the lug nuts to specifications (usually 100-120 ft-lbs).
Pump the brake pedal to ensure proper brake pad seating and fluid pressure.
