Vibration (front end)
 

I have new problem with my 930

I have replace front and rear brake rotors as well as pads. (just made 80 miles)
I have some vibration at 65-75 mph speed on steering wheel.
During braking from this or higher speed I have even more vibration.
I have balance front wheel and result is the same.
Tires are OK too.
Bearings are Ok ( I checked it when replace rotors).
What about running in rotors?
I have made alignment as well all factory set up
(without camber that I set to rear -1.5 and front -1.0)

Any idea?:confused:

If the rotor & pads are all you've changed, put a dial indicator on the rotors and see if you have excessive run out. A large piece of crud between the rotor and hub could mimic the "pedal wobble" of a warped rotor or cause vibration under braking.

Had a similar problem with my 86 Carrera. My steering rack was coming apart. Symptoms were some "wheel shake" aroung 60-70 mph and a lot of the same under hard braking.
