Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for warping using a rotor gauge. If warped beyond specification, replace.
Replace Rotors:
- Remove caliper bolts using a socket set to free the caliper.
- Slide off the caliper and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old rotor by unscrewing any retaining screws.
- Install the new rotor, ensuring it sits flush and is secure.

4. Inspect and Replace Brake Pads

Check the brake pads for wear.
If worn, remove the old pads from the caliper bracket.
Clean the caliper bracket with brake cleaner.
Install new pads, ensuring they fit snugly.

5. Reassemble and Bleed Brakes

Reattach the caliper over the new pads and secure it with bolts.
Reinstall the wheel and lug nuts.
Lower the vehicle and reconnect the negative battery terminal.
Bleed the brake system to remove any air using a brake bleeder kit.
