Get one off ebay, then you can try all these things on BOTH of them...

hey guys, will a cb500 caliper fit a 550?

[bryanj]

Yup

Propane torch+penetrating oil.  Then put it in a vice to push it in, then back on the MC to push it out.  Repeat until you win.

I'd probably get another to have on hand anyway because that piston is probably toast, and the caliper might be too corroded inside too. 

You still need to win though. -not by destroying it.  You can do that after you win if it's no good.

I GOT THE MOTHER UCKFER OUT!  i drilled a holle directly into the backing on the pad till it just started to hit the piston i then put a bolt in and began cuting threads driving the bolt down it hit the top of the piston pushing it backward and freeing it up, i then hit the caliper with a torch then beat on it- torch beat on- it torch until i finaly got the backing to move its right at the ver edge but i burned the #$%* out of myself and had to get some ice. thought i would let you all know sice im sure you all care so much. im headed back down to the shop to get her done

and i have to thank scott ( 78SS) for the idea with the bolt into the middle, Thanks man!
