Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts slightly.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Brake Rotor Inspection and Replacement

Inspect Rotors:
- Check for warping using a dial indicator or by visually inspecting surface.
Replace Rotors (if warped):
- Remove caliper bolts with a socket and ratchet.
- Carefully slide the caliper off the rotor and support it with a bungee cord.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor and secure any retaining screws.

4. Brake Pad Inspection and Replacement

Inspect Pads:
- Check for thickness; replace if below 3mm.
Replace Pads (if necessary):
- Remove the caliper bracket bolts and slide off the caliper.
- Remove the old pads from the bracket.
- Install the new pads ensuring proper orientation and alignment.
- Reattach the caliper over the new pads and tighten bolts to manufacturer's specifications.

5. Reassembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually around 80-100 ft-lbs, check owner’s manual).
Repeat for all wheels if necessary.
