Brake calipers

[orangeGMC]

In your instructions for the disc brake conversion, at the bottom you inform about heavy duty 3/4 ton calipers with a larger piston. My local auto parts stores only lists one for 3/4 ton. Do you have a part number I could cross reference, or a specific vehicle I should look up?

1/2 ton is one size. the 3/4 ton is the bigger one. i run the 1/2 ton and it works great on my 1 ton that is 6500lbs of all truck. the piston isnt that much bigger just by looking at it.

There are two GVW's for the 1983 3/4 ton P/U: 7400 and 8600 lbs. The Wagner re-manufactured (unloaded) caliper part numbers should be CR98954 and CR98955. If nothing else, tell the parts person you want calipers for a 1983 3/4-ton P/U with a GVW of 8600 lbs. Hope this helps.

There you go! Keep in mind that most lifted vehicles (especially shorter ones like K5's) need less rear brake than front so you may want to stick with the smaller calipers to help keep your brake bias a bit more in line.

I have 1/2 ton in the rear and was going to try to use the largest I could on the front.
