Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands for safety.
Remove the wheel on the affected side using a socket set.

3. Inspect and Replace Brake Rotors

Inspection:
- Remove caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
- Check rotors for warping using a dial indicator; replace if the runout exceeds manufacturer specifications (typically 0.002 inches).
Replacement:
- If replacement is required, remove the old rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor, ensuring it is seated properly. Torque the retaining screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if below 3mm.
Remove the old pads from the caliper bracket.
Install new brake pads, ensuring they are positioned correctly and seated in the caliper bracket.

5. Reassemble Components

Reattach the brake caliper, ensuring bolts are tightened to manufacturer torque specifications.
Reinstall the wheel and lower the vehicle.
Repeat the process for the opposite side if necessary.
