90 Chevy Astro Braking

When ever i brake the steering wheel going back and forth, what would cause this. i just got new brakes and rotors, thought that was the problem but it didnt help any.

Your calipers maybe slipping?

Bad tires

Bad steering bearing

Front steering dampner

If it only does it when you brake, it is still rotors or calipers. Take it back, the repairs should be guaranteed.

Wink

Have you checked your tie rod ends?? Worn steering parts could cause the same concern as warped rotors. Jack up one (front) wheel at a time and see if there is any side to side movement.

And let's not forget the idler arms.........There should be 2 on this unit and they're NOTORIOUS for causing vibration problems.........Anything the brakes start as far as shimmy goes, gets picked up by the loose front end parts.........amplified thusly and then it's HANG ON time........

Does the tire move when you push and pull on it from the 12 and 6 o'clock position? IF it does, then you may have a bad bearing.

My car currently has a bad bearing, makes no noise, but the steering wheel has a slight shimmy in it. I just haven't replaced it yet.
