Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, dial indicator
Remove the wheel to access the brake assembly.
Measure rotor thickness and run-out with a dial indicator; replace if out of spec.
If rotors are warped, remove the caliper and bracket, then unbolt the rotor.
Clean the hub surface and install the new rotor.
Reinstall the caliper and bracket, ensuring to torque bolts to manufacturer's specifications.

3. Inspect and Replace Brake Pads

Tools Required: Piston tool, socket set
Check the brake pads for wear; replace if they are below the minimum thickness.
Remove the caliper and compress the caliper piston using a piston tool.
Replace the brake pads and ensure they are seated correctly.
Reinstall the caliper and torque bolts to specifications.

4. Wheel Alignment and Balancing

Tools Required: Alignment machine, balancing machine
Check wheel alignment using alignment equipment; adjust as necessary.
Balance the wheels if they show any imbalance that could cause vibrations.
