Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner.

2. Lift the Vehicle

Use the jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using the lug wrench.

3. Inspect and Measure Brake Rotors

Remove the brake caliper by unbolting it from the mounting bracket.
Hang the caliper using a wire or bungee cord to avoid straining the brake line.
Remove the brake pads and examine for uneven wear.
Use the dial indicator to measure rotor runout. If the runout exceeds manufacturer specifications (typically 0.002 inches), the rotor is warped and needs to be resurfaced or replaced.

4. Replace or Resurface Rotors

If rotors are warped, either resurface them if within thickness limits or replace them with new rotors.
Parts Required: New brake rotors (if needed), new brake pads (recommended for even wear).
Torque Values: Refer to the manufacturer specifications for caliper and wheel lug nut torque.

5. Reassemble

Clean the rotor surface with brake cleaner before installation.
Install the new or resurfaced rotors.
Reinstall the brake pads and caliper.
Torque caliper bolts to manufacturer specifications.
Reattach the wheel and torque the lug nuts to manufacturer specifications.

6. Lower the Vehicle

Carefully remove jack stands and lower the vehicle to the ground.
