Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (optional for electronic components).

2. Inspect and Replace Brake Rotors

Lift Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
Remove Wheel: Use a socket set to remove the wheel lug nuts and take off the wheel.
Inspect Rotors: Check for warping using a dial indicator or visually inspect for grooves and uneven wear.
Replace Rotors (if needed):
- Remove caliper mounting bolts using a socket.
- Carefully slide the caliper off the rotor.
- Remove the rotor from the hub.
- Install a new rotor, ensuring it is free of debris.
- Reinstall the caliper and secure with bolts to manufacturer’s torque specifications.

3. Check and Replace Brake Pads

Inspect Brake Pads: Look for uneven wear or contamination.
Replace Pads (if necessary):
- Remove the caliper as described above.
- Slide out the old brake pads.
- Install new pads, ensuring they are properly seated and aligned.
- Reassemble the caliper and secure it with bolts.

4. Wheel Alignment and Balancing

Check Alignment: Take the vehicle to a professional for alignment if uneven tire wear is noted.
