Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check rotors for warping using a dial indicator; replace if runout exceeds manufacturer specifications (typically 0.002-0.005 inches).
2. For replacement, remove caliper bolts and slide the caliper off the rotor.
3. Remove the rotor by unscrewing the retaining screws or using a mallet if stuck.
4. Install the new rotor, ensuring it is secured properly.

4. Inspect and Replace Brake Pads (if necessary)

Sub-steps:
1. Remove the caliper bracket bolts to access the pads.
2. Slide out the old brake pads and inspect for uneven wear.
3. Install new brake pads, ensuring they are correctly aligned.
4. Reassemble the caliper and tighten bolts to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back on, hand-tighten the lug nuts.
2. Lower the vehicle and then use a torque wrench to tighten the lug nuts to the specified torque (usually around 100-150 ft-lbs).
