Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Wheels

Use a jack to lift the vehicle and support it with jack stands.
Remove lug nuts using a socket wrench and take off the wheels.

3. Inspect and Replace Brake Rotors

Inspect: Check rotor surfaces for warping or scoring.
- Tools Required: Micrometer, brake cleaner, safety glasses.
Replace if necessary: If rotors are warped (beyond manufacturer's specifications), remove the caliper by unscrewing the caliper bolts.
- Sub-steps:
  - Remove brake pads from the caliper bracket.
  - Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
  - Install new rotors, ensuring they are properly aligned and secured.

4. Replace Brake Pads

Remove the old pads from the caliper bracket.
Tools Required: Torque wrench, brake grease.
Apply brake grease to the back of the new pads to prevent noise.
Install new brake pads into the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the new pads and rotors, tightening the caliper bolts to manufacturer specifications.
Reinstall the wheels and lug nuts, tightening them in a star pattern to ensure even pressure.
Lower the vehicle and reconnect the battery.
