Guys, why are the brakes so bad on these trucks? I mean, 13x21/2 shoes, duel m/c, should stop these trucks no problem. I've driven other trucks w/o power brakes and they seem to stop alright. ???????. Also, any feed back on mounting the rear springs under the frame when i get around to putting the 14 in? I think it's stupid to have to remove all the hardware from the axle and stuff just to install soring bushings. My,02.
