Steering wheel/front vibrate when braking at highway speed

How good are the brake shoes /drums up front? Could the car use a brake job? If the shoes are thin, the drums would be worn too.
If you are driving it more now, and the shoes are getting thin, it sure wouldnt hurt to just replace the shoes and turn the drums anyway. As long as theres enough meat on the drums to turn them (again). If thats the problem, youd know right away. If not, you still have new brakes.

Otherwise you could measure/check the ID with a dial indicator.
