Solution

1. Preparation

Tools Required: Floor jack, jack stands, lug wrench, torque wrench, runout gauge, alignment machine.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Inspect and Replace Brake Pads

Remove the wheel:
- Loosen lug nuts slightly.
- Lift the vehicle using a floor jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Remove caliper:
- Locate and remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it without stressing the brake line.
Inspect brake pads:
- Check the brake pads for thickness; replace if worn unevenly.
- If necessary, remove the old pads and install new ones, ensuring they are seated correctly.

3. Resurface or Replace Brake Rotors

Inspect rotors:
- Use a runout gauge to check for warping; any runout over specifications indicates replacement or resurfacing is needed.
Remove rotor:
- If necessary, remove any retaining screws and slide the rotor off the hub.
Resurface or replace:
- If resurfacing, follow manufacturer specifications; if replacing, ensure the new rotor matches the old one.

4. Check and Adjust Wheel Alignment

Set up alignment machine:
- Position the vehicle on the alignment rack.
Perform alignment:
- Follow the machine’s instructions to measure and adjust camber, caster, and toe to manufacturer specifications.
Test drive after alignment:
- Ensure steering wheel is centered and vehicle tracks straight.

5. Reassemble and Torque Components

Reattach caliper and wheel:
- Reinstall the caliper over the new pads, tightening the mounting bolts to specified torque.
- Place the wheel back on and hand-tighten the lug nuts.
Lower vehicle:
- Remove jack stands and lower the vehicle back to the ground.
Torque lug nuts:
- Using a torque wrench, tighten the lug nuts to manufacturer specifications in a crisscross pattern.
