Im having a bad, BAD shaking problem on my truck when stopping. I have checked the brakes and they seem fine, about 7mm left on pads, rotors show no warpage or glazing. Everything on the front of the truck is new, minus the shafts in front axle. This shake is an "up and down" type shake when you hit the brakes....any ideas?

 

have you inspected the rear brakes?

 

i had almost the same exact problem on my w150 it would shake really bad wile braking at like 35 mph so i jacked the front end up and the rear end and put it in 4 wheel drive and brung it up to speed and then hit the breaks and have somebody watch the front end and see what tire shook what the problem was for me is that my wheel bearings were loose so tighten them up and they then took it for a ride and it was fine maybe the same problem for you hope it helps
