Hi all.

I have some problem with vibration when braking from high speed. When driving in the city all looks fine. However when driving around 90mph and start braking brake pedal starts vibrating till around 50 mph(steering wheel too but not as much as pedal). Below 50mph there is no vibration or is impossible to feel.

Does any body know what can be a reason of it. Someone said to me that brake discs maybe out of shape or about to end. If yes which one front or rear? Week ago was changing front tyres and when tyres were taken out of axle I was trying to turn the discs around. It was possible however very hard. Today was changing rear tyres and I could have turned rear disc much more easier then front one. Does it mean that front one are out of shape.

Or maybe something completely different. Do you have any idea. Just to mention that camber and alignment is done and is correct?

Thank you for any help
