Solution

1. Preparation

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

2. Lift the Vehicle

Use the jack to lift the front of the vehicle.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use the lug wrench to remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect: Use a dial indicator to measure rotor run-out. If it exceeds manufacturer specifications, replace the rotors.
Replace:
- Remove caliper bolts and slide the caliper off the rotor.
- Remove the rotor by unscrewing any retaining screws if present.
- Install new rotors, ensuring they are clean and free of grease.
- Torque to manufacturer specifications (typically around 80-100 ft-lbs).

5. Inspect and Replace Brake Pads

Inspect: Check brake pads for wear. If they are less than 3mm thick, replace them.
Replace:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the bracket and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the bracket.
- Install new pads, ensuring they fit properly in the caliper bracket.
- Reinstall the caliper and torque bolts according to specifications (typically around 25-30 ft-lbs).

6. Reassemble and Lower the Vehicle

Reinstall the wheel, hand-tighten lug nuts, and lower the vehicle.
Use a torque wrench to properly torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).
