Rebuilding the front calipers on my 82 yota truck. the calipers are stock but when i called autozone they said that there are three different kits, 1 ton, 3/4 ton, and 1/2 ton. which one do i get. are they all the same? The 3/4 ton caliper kit is the cheapest. What kind of truck do i ahve? 1/2 ton or 3/4 ton? How can i tell? WT u gotta know something
