Had front wheels balanced did not stop the problem.I suspect drive shaft problem. Am I correct? Car shakes when braking.

Usually brake rotors that are out of round or have hot spots will cause this have a shop check this and check prices here
when vibating when braking at higher speeds probably is the rotors. The rotors need to be resurfaced. If u can, run your fingers along the front rotors inside towards the outside and if it is very rough it this may fix your problem.I would do this before spending money for a driveshaft
