919 Braking question????

Okay, recently purchased a used 2002 919. Nice bike, comfy and runs well, some polishing and cleaning, oil change and she is looking/running well. My questions, I was told the brakes had been replaced by GSXR1000 brakes w/ new brake lines. When braking normally, the brakes seem fine. When REALLY braking it gets quite a bit of vibration, feels similar to a jack hammer, it still brakes but has a vibration. Not sure if this is due to the suspension or the brakes themselves. I might also be more sensitive to it since my 600RR doesnt do it. Any ideas or thoughts?

Thanks

Put the bike on the stand, rotate the wheel and see if it makes a noise at a certain point of the rotation. Your rotor could be warped.

I'd start from there.

He might be talking about that weird rear wheel hop if you lock up the rear wheel under hard braking. I don't do it often but have experienced some hopping and jolting if the rear locks up.

Havent done that yet, though I have heard of it on here, my problem is with the front of the bike. Not sure if it is suspension or braking causing it. Just wanted to know if anyone else has experience with it and what caused/fixed it.

Thanks
