Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use jack stands to elevate the vehicle safely.

2. Remove Wheels

Loosen lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial indicator to measure rotor runout; if warped beyond specifications, replace.
Remove Rotors: Unbolt the caliper bracket and remove the caliper. Hang the caliper using a bungee cord to avoid stress on the brake line.
Replace Rotors: Install new rotors, ensuring they are clean and free of grease.

4. Inspect and Replace Brake Pads

Check Pads: Examine the thickness of the brake pads; replace if below manufacturer specifications.
Install New Pads: Apply brake grease to the back of the pads to prevent noise and install them in the caliper bracket.

5. Reassemble and Torque Components

Reattach Calipers: Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Reinstall Wheels: Place the wheels back on the vehicle, hand-tighten the lug nuts, and lower the vehicle.
Torque Lug Nuts: Tighten the lug nuts in a star pattern to the specified torque.
