Help I cant Stop!!

[eventytoo]

HI all. I own a 1976 GMC 4x4. I did the resto myself. One thing this truck needs is some better brakes. I replaced all the components when I restored it but this truck dont stop!!!! I drive an 04 silver half all week and I jump in this thing durring the weekend and have darn near plowed a few cars over. I feel like im driven a loaded 18 wheeler. Its that scarry.

Well I would like some help. I need to upgrade the brakes so I dont hirt myself or kill somone in this thing. Yes the stock brakes are in proper order. The rear will lock when I stand on the peddle leaving two black streeks behind me.

I have corrected the rear track width with wheel spacers 2 inch on both side a total of 4 inches in the rear. I did this for looks so both front and rear are the same. I would like to do away with this.

Wheels and tires are 16inch alloys 35 inch tall tires Lots of rotating mass here. I do not want to go with a bigger wheel.

This is my thoughts, Go with a hydro-boost? being im running a cam with 13'' vac at idle. And finding a rear axle out of a newer truck with disks already on it.
