Hope someone can help (Eric Shea? are you out there?). I rebuilt the rear calipers on my 71, and went to adjust the venting clearance on the right side and ran into a problem. The adjuster on the outside half just spins without pushing out the piston. I am guessing I assembled it incorrectly but when putting it back together I swear everything was working (2 weeks ago), now it just spins. (IMG:style_emoticons/default/mad.gif)

Hope someone comes up with easy solution, or else tomorrow off it comes and I will tear it apart and check it out.

Oh, by the way, thanks Eric Shea for the rebuild write up in the Classic Forum, could not have done it without you.

by the way, please do not totally wear out your pads or you may see this


LOL I have one of those on my bench as well (IMG:style_emoticons/default/av-943.gif)

I'm "guessing" the spring mechanism in the lower left hand corner of Dave's previous picture may not be snapped into place where the 90 degree bend at the top (in that picture) is.

I haven't seen the "Crusty One" weigh in here but he would say do not pull them in without a thumb on them. This helps aleviate the strain on this spring preventing it from popping out.

You can drop a stop piece down the adjuster hole and screw the adjuster in as seen in the last picture posted here. Once the adjuster hits the stop piece it will begin pull the mechanism out of the piston. This is kinda advanced stuff and I don't really recommend you try it without knowing what you're getting into.

It may simply be the internal mechanism spinning. You may want to try high speed bursts with an air wrench in the "COUNTER" clockwise direction. Believe it or not, this has been known to get it moving. Try that "first". If that doesn't cure it, PM me and I can get you another piston.

You "can" get that pitson out without it working. Simple take the clip and nut off and tap the adjuster in with a plastic or brass mallet. You will see the piston begin to move out as the adjuster taps in. Once the adjuster gets close to the caliper surface, back it out and tap it again. If it keeps spinning simply tap the piston out with a long 4mm hex. Make sense? This is how I remove all of my outer pistons as I simply don't like using the adjuster on old grundgy calipers. It helps save the adjuster for future use.

Good luck.
