Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect Brake Components

Tools Required: Jack, jack stands, torque wrench, inspection mirror.
Lift the vehicle using the jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if less than 3mm.
Check the brake rotors for warping using a dial indicator; replace if warped.

3. Check Wheel Alignment

Tools Required: Alignment machine (or take to a professional).
Measure the alignment settings and adjust as necessary to manufacturer specifications.
Ensure that the vehicle is properly aligned to avoid vibrations during braking.

4. Inspect Suspension Components

Tools Required: Wrench set, inspection tools.
Examine shock absorbers, struts, and control arms for wear or damage.
Replace any worn or damaged components as needed.

5. Reassemble and Test

Reattach the wheel and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Lower the vehicle back to the ground.
Conduct a test drive to verify that the vibrations have been resolved.
