Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Check rotors for warping using a run-out gauge. Replace if out of specification (usually more than 0.002 inches).
Replacement:
- Use a socket set to remove the caliper and bracket.
- Remove the old rotor by sliding it off the hub.
- Clean the hub surface with a wire brush to ensure proper rotor seating.
- Install the new rotor and secure it with the appropriate torque (usually around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Remove the caliper and bracket assembly.
Slide out the old brake pads and inspect for wear.
If replacement is necessary, install new pads, ensuring they are oriented correctly.
Apply brake grease to the back of the pads to reduce noise.

5. Reassemble and Test

Reattach the caliper and bracket, ensuring all bolts are torqued to specifications.
Reinstall the wheel and lug nuts, torquing them to the manufacturer's specification.
Lower the vehicle, reconnect the battery, and pump the brake pedal to ensure proper brake operation.
