Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working near electrical components.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a caliper gauge to measure rotor thickness and check for warping.
- If warped or below minimum thickness, proceed to replace.
Remove Rotors:
- Unscrew any retaining screws and slide the rotor off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it with retaining screws.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check the thickness of the brake pads; replace if they are below 3mm.
Remove Calipers:
- Unbolt the caliper from the bracket using a socket set.
- Hang the caliper using a bungee cord to avoid straining the brake line.
Replace Pads:
- Slide the old pads out of the caliper bracket and install new pads.
- Reinstall the caliper over the new pads and secure it with bolts.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 75-90 ft-lbs).
Reconnect the battery if disconnected.
