Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Rotors

Remove the wheel: Use a jack to lift the vehicle and a lug wrench to remove the wheel.
Inspect the rotors: Check for warping or scoring. If warped, proceed to replace.
Remove caliper: Unbolt the caliper from the bracket and hang it using a bungee cord (do not let it hang by the brake line).
Remove rotor: Remove any retaining screws and slide the rotor off the hub.
Install new rotor: Clean the hub surface, then install the new rotor, ensuring it is seated properly.

3. Replace Brake Pads

Remove brake pads: Slide the old pads out of the caliper bracket.
Inspect caliper: Look for wear on the caliper and ensure it moves freely.
Install new brake pads: Position new pads in the caliper bracket, ensuring proper alignment.
Reattach caliper: Position the caliper back over the new pads and bolt it securely.

4. Inspect and Replace Suspension Components (if needed)

Check ball joints and tie rods: Use a pry bar to check for excessive play.
Replace worn components: If any parts are worn, remove and replace them according to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel: Place the wheel back on and hand-tighten lug nuts.
Lower the vehicle: Remove the jack and fully tighten lug nuts in a star pattern to the manufacturer’s torque specification.
Reconnect the battery: If it was disconnected, reconnect it.
