Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, micrometer.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Use a socket wrench to remove the caliper bolts and slide the caliper off the rotor.
Carefully remove the old brake pads from the caliper bracket.
Check the caliper slides for any corrosion and apply brake grease if necessary.
Install new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and tighten caliper bolts to the manufacturer's torque specifications.

4. Inspect and Replace Brake Rotors (if needed)

If rotors are damaged or below minimum thickness, remove the rotor by unscrewing the retaining screws (if equipped).
Clean the hub surface and install new rotors, ensuring they are properly seated.
Reinstall the wheel and hand-tighten the lug nuts.

5. Reassemble and Lower Vehicle

Lower the vehicle from the jack stands and remove wheel chocks.
Tighten lug nuts in a crisscross pattern to the specified torque.
Pump the brake pedal a few times to seat the brake pads against the rotors.
