Front caliper spring ID (pictures)?
I had a leak on one of my previously rebuilt front calipers (front washer between the halves on the end), so I decided to pull both calipers and rebuild them with an up graded o-ring kit.
after taking apart the 2 calipers (both previously replaced by the last owner) one had what I would call "Normal" springs, the other had elongated springs that had obvious differences than the first set. I had another doner front caliper available so I pulled it apart and it had the "normal" size springs in it.
my question is why is this set of springs so different and should I re-use them or use the other set of "normal" springs so they (both sets) have matching spring rates?
longer one on the left and normal one on the right

(Didn't GM develop O-rings in the 1980s that retracted the puck slightly to prevent the pads from dragging on the rotors?)

Why not put fresh ones in? They only cost $3 to $4 each from vb&p or Cssb. It's little enough to assure that you have good consistent brakes. You've already invested a lot of time in fixing them.

If that is the case why do the O-ring calipers I am rebuilding have springe? AND why do the O-ring kits I am installing also have springs?
If the OP is interested, I will send him the springs I removed for the cost of shipping. PM me if interested.

I have new springs for 2 calipers, I just wanted to know why there were 4 odd springs in one of the calipers I took apart. I thought they were stock springs as well that were stretched out but the 4 odd ones actually have a smaller ring diameter on the end coil and a slight bulge in the center as compared to a stock one?
I am intrigued by the statements of not using the springs with a new o-ring up grade kit? So when I rebuild these I should not put the springs back in at all?
