I see you have the nice green plastic pistons that swell up and stick in the bores. Mopar had a big problem with those and our new `76 new yorker was off the road for a week or so with seized brakes waiting on chrysler to replace the calipers. They couldn`t get the parts so I took the car back and sanded the plastic junk pistons down to the correct size.



Hmmmmmmmmm. More info, if you please.

Was there a TSB?

I will say that the tolerances seemed awfully tight...

Are you saying that all phenolic pistons are junk or just the original ones or just certain part numbers or certain batches or the caliper bores were undersize or what?

Down to just a blue car now.
