Solution

1. Preparation

Tools Required: Jack stands, wheel chocks, socket set, torque wrench, dial indicator.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before beginning any work.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the Wheel: Loosen lug nuts and remove the wheel to access the brake components.
2. Inspect Rotors: Use a dial indicator to check for warping. If the runout exceeds manufacturer specifications, the rotor must be resurfaced or replaced.
3. Replace Rotors: If needed, remove the caliper and bracket, then take off the old rotors. Install new rotors, ensuring correct orientation.
4. Reinstall Caliper and Wheel: Reattach the caliper and torque bolts to the manufacturer's specifications. Reinstall the wheel and torque lug nuts in a star pattern.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check Pad Thickness: Measure the brake pad thickness; if less than 3mm, replace them.
2. Remove Old Pads: Take off the caliper bracket and remove the old pads.
3. Install New Pads: Apply brake grease to the backing plates of new pads and install them in the caliper bracket.
4. Reassemble: Reattach the caliper and secure all bolts to the specified torque.

4. Tire and Wheel Inspection

Sub-steps:
1. Visual Inspection: Check tires for uneven wear or damage.
2. Balance Tires: If any imbalances are noticed, have the tires balanced at a service center.
3. Check Pressure: Inflate tires to the recommended PSI as per the vehicle's specifications.

5. Wheel Alignment

Sub-steps:
1. Measure Alignment: Use a professional alignment machine to check the vehicle's alignment settings.
2. Adjust Alignment: If misaligned, adjust the camber, toe, and caster as necessary to return to specifications.
