Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheels

Tools Required: Socket set, jack stands, lug wrench
Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors

Inspect the rotors using a dial indicator to check for warping.
If warped or excessively worn, remove the caliper bracket bolts and slide the caliper off.
Remove the rotor by unscrewing the retaining screws (if equipped) and pulling it off the hub.
Install the new rotor, ensuring it is seated properly on the hub.
Reinstall the caliper and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake pad wear indicators and replace any pads that are worn unevenly.
Apply brake grease to the back of the new pads and install them into the caliper bracket.
Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the specified torque value in a star pattern.
