Solution

1. Preparation

Gather tools and materials: jack, jack stands, lug wrench, torque wrench, dial indicator, brake cleaner.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electronic components.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the issue is suspected).
Secure with jack stands to ensure safety.

3. Inspect Brake Components

Brake Rotor Inspection:
- Remove the wheel using a lug wrench.
- Use a dial indicator to check rotor runout. Rotate the rotor and measure at several points.
- If runout exceeds specifications (typically 0.002-0.003 inches), the rotor may need resurfacing or replacing.
Brake Pad Inspection:
- Check the thickness of the brake pads. Replace if they are below the minimum thickness (usually around 3 mm).
- Ensure pads have even wear; replace pads if uneven.

4. Check Suspension and Alignment

Inspect control arms, bushings, and other suspension components for wear.
If any parts are damaged or worn, replace them as necessary.
Consider a wheel alignment check; perform adjustments if necessary.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (often around 80-100 ft-lbs).
Lower the vehicle and reconnect the battery if disconnected.
Test drive to confirm that the issue is resolved and braking is smooth.
