When rebuilding Alloy S calipers, what is the trick to getting the piston back in the bore? I put the springs back in the SS pistons, but can only seem to get the piston 1/4 of the way in. I used a clamp to apply pressure and the piston goes in, but as soon as the clamp is removed, the spring back out. What am I doing wrong?

I'm guessing it is hanging up on the seals. Mark & measure to find out. Sometimes you do have to rotate the pistons to get them into the seals. Did you put in new seals? If so, try putting in an old seal and force it in. Then you will get an idea of the force required. Most pistons are well rounded to help the transition. Haven't tried the stainless pistons yet.
One of my next tricks is to make a copy of the GT caliper I have so I can have a pair. I'm sure that they can be overbored enough. Then I'll need a new set of pistons for sure. DaveP |
