I've camry 2008 GL and I feel vibration when i put break while driving my car on 100+ speed.
I recently replaced the engine mounting as well....any suggestion what problem it could be?

 

Brake rotors

 

Awesome, it works! thanks a lot for the help

 

Warped rotors. Just got a set of black coated rotors from brakeperformance.com and that also fixed my vibration while braking. Also, make sure when you brake in your new rotors that you don't heat them up and then just sit on them as that can warp the rotors again.
