Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
- Raise the vehicle using a jack and secure it with jack stands.
- Completely remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, floor jack, jack stands.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Inspect the brake rotors for warping using a dial indicator. If runout exceeds manufacturer specifications (typically 0.002 inches), replace the rotors.
- Remove the caliper by unbolting it and hang it securely to avoid straining the brake line.
- Remove the old rotor by unscrewing any retaining screws or clips and sliding it off the hub.
- Install the new rotor, securing it with retaining screws or clips.
Tools Required: Dial indicator, wrench set, brake cleaner.

4. Replace Brake Pads

Sub-steps:
- Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
- Remove the caliper bracket by unbolting it.
- Take out the old brake pads from the caliper.
- Install new brake pads into the caliper and reattach the caliper bracket.
Tools Required: Wrench set, brake pad spreader.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle off the jack stands and tighten lug nuts to the manufacturer's torque specification (typically 80-90 ft-lbs).
- Reconnect the battery and start the vehicle.
Tools Required: Torque wrench.
