I just got my bike back from the shop, had a few repairs and other stuff dun, one thing is I had braded lines put on, which brings me to my problem, I had a slight vibration through the bars before this but now it’s a lot worse under light medium braking.
I’ve checked my disks and they seam a bit glassed but not that bad, if I brake hard enough to get the rear of the ground it go’s away, anyone have an idea

 

My only idea is a warped rotor.

 

^ check that and check your front wheel bearings
