I haven't had any problems with the mirrors on my 91 KLR. At highway speeds they are still quite usable. As for the breaks, they are indeed not the best, however, in my opinion they are adequate and much better than some bikes I've had in the past. The brakes can be improved somewhat by replacing the front break line with a stainless steel type. You could replace the rear one as well, but I didn't see the point as it as short compaired to the front. Also, I replaced the pads on both front and rear with a better set made by Galfer (I think). Good luck.
