Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Raise Vehicle

Use a floor jack to lift the front of the vehicle.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the front wheels.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Check for warping using a dial indicator or by visual inspection for uneven surfaces.
- If warped or damaged, proceed to replace.
Remove Caliper: Unbolt the brake caliper using a socket set. Support it with a bungee cord (do not let it hang by the brake line).
Remove Rotor: Unscrew the rotor retaining screws (if equipped) and slide the rotor off the hub.
Install New Rotor: Place the new rotor onto the hub, ensuring it is seated properly.

5. Inspect and Replace Brake Pads

Check Pads: Assess the thickness of the brake pads; replace if less than 3mm.
Remove Old Pads: Slide out the old pads from the caliper bracket.
Install New Pads: Insert new brake pads into the caliper bracket.

6. Reassemble Components

Reattach Caliper: Position the caliper back over the new pads and rotor, and bolt it in place.
Reinstall Wheel: Place the wheel back on the hub, hand-tighten the lug nuts.

7. Lower Vehicle and Torque Lug Nuts

Carefully remove the jack stands and lower the vehicle.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (often around 80-100 ft-lbs, check vehicle manual).
