Brake vibration

I feel my steering wheel vibrate when braking from 60mph or more.
Mine has standard steel brake. Anybody experience this?

Sounds like you have warped rotors and the front discs and pads should be replaced.

Also check tire balance. I once had braking-induced steering shake that went away with a tire re-balance.<!-- google_ad_section_end --> <!-- / message --><!-- edit note -->

above issue is only a tire balance issue, but that will be felt at a certain speed, not during braking.

during braking the wheel shake is caused by warped rotors as stated in the 2 post, change the pads and rotors

Is the pad surface glazing and must be cleaned, because I see a little glaze on the disc.
The car just only has 6000 miles.

+1 Pad deposits on the rotor can cause this problem. I doubt you got the rotors hot enough on the street to wrap the rotors.

I just brought it to the dealer.
The disc is resurfaced, and pad is changed (pad has lots of hairy cracks, maybe it's hardened overtime)

You can't resurface drilled rotors.
