brake components may be sticking/dragging
Or, you may have 2 issues, vibration on braking can be uneven pad material deposition.
if you have good brake pad material left on the present pads, locate a section of roadway where you can safely do the following;
at about 30-40 mph, brake with the left foot while maintaining speed. You should feel the car straining. Not huge, emergency stop pressure, but enough to feel the car pulling against the brakes. Do that for 2-3 blocks - say - 1/8 mile. MOST IMPORTANT - now drive for a mile or so to cool the brakes - NO STOPPING. IF you MUST stop when doing this, hold the car with the emergency brake. Choose the road for this experiment carefully.
If there is improvement in the shaking when braking problem, you can do this again and see if it gets even smoother.
There are more intense brake bedding-in procedures, but this can help. If the problem is the same or gets worse, you likely will need new rotors, or you have a stuck caliper or other problems.
