Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if needed for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, dial indicator, jack and jack stands.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using the socket set.
Use the dial indicator to check for rotor warping by placing the indicator on the rotor surface and rotating it. If the runout exceeds specifications (usually around 0.002 inches), replace the rotor.
If replacing, remove the caliper and bracket, then unbolt the rotor.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor and reassemble the caliper and bracket, tightening bolts to the manufacturer's torque specification (typically 75-100 lb-ft).

3. Inspect and Replace Brake Pads

Inspect the brake pads for uneven wear; if they are worn below the manufacturer's specifications, replace them.
Use the socket set to remove the caliper bolts and slide the caliper off the pads.
Replace the pads, ensuring they are properly seated and aligned.
Reinstall the caliper and tighten bolts to the manufacturer's torque specifications.

4. Check Wheel Alignment and Tire Balance

Take the vehicle to a professional for alignment and balance check if needed.
Adjust or replace components as necessary based on findings.
