OK here's some history.
Converted the wagon to 73 Disc brake set-up 8 years ago(?), and I have had continuing problems with brakes all around on the wagon. When I put the 73 set-up on the wagon I only re-used the spindles and caliper brackets...everything else was reman'd or new.
I have had a lot of brake issues over the years. Seems to be the one major issue with the wagon. Currently I have drilled and slotted front rotors. Rear disc brake set-up from Scarebord on the 8 3/4 in the back. Reman'd disc brake booster, 80's 5th Ave master cylinder. No proportioning valve, straight off the MC to the front calipers, and an adjustable brake valve for the rear lines.
So what's happening now is this.... I replaced the front calipers last year, since I had one side that was dragging. This solved that problem, but now I have a major "Clunk" when applying the brakes, softly or hard. I have cop car rims on the wagon and have had a friend watch what was going on while braking. Seems that the calipers are grabbing the rotor and then flexing, moving on the pins and hitting the caliper mounts. I replaced the pins thinking that might be my issue...but the problem persists.
Only thing I can think of is the durometer rating of the rubber bushing in the caliper ears is a lot softer then it should be? My older reman'd calipers I removed never had this problem.
So after all that I finally get to my question. Can I swap a set of 74-78 caliper brackets and calipers onto my 73 spindles and rotors? The fact that the Formal set-up does not have any rubber bushings or pins in the system appeals to me and my current situation.
Thoughts?
