I did supervise one upgrade this past week to the Blazer. With the added weight of the tires, bumpers, etc., the brakes were not up to the task of locking down on the rotors. I was thinking hydroboost, but after a quick call to Chris at Offroad Design, I learned that there was a bolt on upgrade. Apparently the mid-80s 3/4 ton trucks had larger piston calipers for the higher GVWR trucks. It's a direct bolt-on upgrade that gives you 20% more clamping force. So for under 100 bucks I can stand this truck up on its front toes. I ordered brake lines from Offroad Design that have the matching 10mm banjo bolts, but if you're 79 and up, you already have the right brake lines. It's awesome. Feels good.
