Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Remove Wheels

Sub-steps:
- Loosen the lug nuts on the wheel(s) before lifting the vehicle.
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheel(s).

3. Inspect Brake Components

Sub-steps:
- Visually inspect the brake rotors for warping or scoring. Use a straight edge to check for flatness.
- Measure rotor thickness with a micrometer; replace if below manufacturer specifications.
- Check brake pads for wear; replace if they are worn down to the indicator.

4. Replace Brake Rotors (if needed)

Sub-steps:
- Remove the caliper bolts and lift the caliper off the rotor.
- Secure the caliper to avoid stress on the brake line.
- Remove the rotor retaining screws, if applicable, and slide the rotor off.
- Install the new rotor and tighten retaining screws to manufacturer specifications.

5. Replace Brake Pads (if needed)

Sub-steps:
- Remove old brake pads from the caliper bracket.
- Compress the caliper piston using a caliper tool to make space for new pads.
- Install new brake pads into the caliper bracket.

6. Reassemble and Test

Sub-steps:
- Reattach the caliper and tighten bolts to manufacturer specifications.
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer's specifications.
- Pump the brake pedal to ensure proper pad seating.
