Front end vibration after new rotor and brakes

no vibration when i brake.. only when crusing at certain speeds above 60 the steering wheel and front end vibrates . wheels out of balance maybe?

sounds like tire balance to me. just weird that it would do it right after new rotors and brakes.

yeah...

yeah i know.. but then again coincidentally it has been real rough out here with the snow and ice and potholes and stuff... im goin after work to the shop to have em check the balance..

Hmmm

Did you scrub the mounting surface real well when you put the new rotors on? I usually take a wire wheel and dress up the surface a bit to make sure that the rotor sits flat and true on the pad, otherwise you will throw the rotating assembly out of balance. Wheel weights won't fix this one.

Are the lug nuts tight.

I had a Cutless Supreme Int. and everytime I had the front wheels removed for work I noticed vibration and noise a day later.

Everytime it turned out that the nuts weren't tight enough. Never found out why that was though.

Thanks for the input guys much appreciated.. went and got 2 new tires today and that solved the problem.. they were kinda shot.. im going for an allignment today.. the wheel is a little off and it pulls slightly.. again thanks!

It sounded like a balance problem, I've also heard that rotors can get out of balance, some aftermarket ones even have weights on them.
