a note for easy switching of front/rear calipers------just switch the lines at the master, you don't need to move the calipers-then see if the fronts react correctly!! saves a lot of time and effort.

Sprags-----if calipers are on wrong side of car????????

And----If during the assembly/rebuilding of the sprag cored calipers------if the sprag was installed backwards it won't work-----same deal if rollers are loaded with rust/crud
