Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheels

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

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a dial indicator gauge to measure rotor runout.
- If warped beyond specifications (typically 0.002 inches), proceed to replace.
Remove Rotors:
- Remove caliper bolts and lift the caliper off the rotor.
- Remove the caliper bracket if necessary, then take off the rotor.
Install New Rotors:
- Clean the hub surface and apply anti-seize lubricant.
- Install the new rotor and reattach the caliper bracket.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Measure pad thickness to ensure they are within service limits.
Replace Pads:
- Remove the old pads from the caliper.
- Compress the caliper piston using a caliper tool to make room for new pads.
- Install new brake pads ensuring proper orientation.

5. Reassemble and Test

Reattach the brake caliper and wheel.
Tighten wheel nuts to manufacturer specifications (typically 80-100 ft-lbs).
Lower the vehicle and remove wheel chocks.
