Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if required for safety.

2. Remove Front Wheel

Use a jack to lift the front of the vehicle and secure with jack stands.
Use a socket set to remove lug nuts and take off the front wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor thickness and warping.
Replacement:
- If warping is found, remove the caliper bracket bolts and detach the brake caliper.
- Remove the old rotor by unscrewing any retaining screws or clips.
- Install the new rotor, ensuring it is seated properly.
- Reattach the caliper and torque bolts to manufacturer's specifications (usually around 20-30 lb-ft).

4. Check and Replace Brake Pads

Remove the caliper from the bracket and inspect the brake pads.
If pads are worn unevenly, replace them with high-quality pads.
Install new pads, ensuring they are aligned correctly in the caliper bracket.
Reattach the caliper and torque bolts to the specified settings.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle from jack stands.
Torque the lug nuts to manufacturer specifications (usually around 80-100 lb-ft).
Reconnect the battery if it was disconnected.
