Put new front rotors and pads on a year ago, worked fine. After about 4 months, I started to get a little steering wheel wobble when braking and put this down to crappy quality rotors. Finally got around to replacing the rotors last night, but now I have a very slight steering wobble all the time. Wobble when braking has improved but has not gone away.

Two caveats:

1) The rotor retaining screw on one side was rusted in and I had to drill off the head and use heat to get it all the way out. Haven't made it to the auto parts store yet to get a new one, but plan on it...and using a dab of anti-seize on it.

2) The brake pads had less than 10K miles of wear on them so I left them in.


Would the absence of the rotor retaining screw cause a wobble? I wouldn't think so.

Should I replace the pads?

It sucks to work on something relatively easy then have it worse off than if I left it alone! :(

I gotta run, but short answer is no, I don't think the rotors are the problem

You have a wobble at all speeds and with or without braking?

Hmmm. Sort of. Just drove it again to the parts store and yes, a tiny bit visible when hands off the wheel. Not able to feel or see it with hands on the wheel. On the way back from the parts store, didn't notice it.

Wobble during braking *almost* gone on the way to the parts store, seems to be gone now. DEFINITELY improved with the new rotors.
