Anybody know any dual piston rear disc models?

[slownugly007]

Im changing out my brake pads and my rear caliper definitely needs a rebuild! The pistons are gouged pretty bad and when I put the new pads on it locked the rear brake due to the pistons not wanting to move freely. I started looking for pistons for the rear but came up blank? In my Clymers manual and everywhere Ive looked tss showing my bike with a single piston rear???? I wonder if the previous owner swapped the rear setup with another model? The pistons I have measure 27mm x 35mm, and Ive found 27mm pistons for 91-96 cb750SC but theyre 31mm tall? Can I use these?

Im trying to get all this stuff ordered and I want to go ahead and rebuild all the calipers while Im at it but now Im wondering what rebuild kit to order for the rear? Any help would........well I guess it would help!?  Thanks guys!

Any Hondas? Mine on my 81 F are dual piston rears but I cant find any parts for them in that year, so Im wondering if the rear setup is of of a different honda or if these models came with dual pistons?

According to this link a dual piston is what it's supposed to be

  I thought you need to mod some for your bike,Then I'm betting ? Gold wings / Iterstates/Mine F2 are the same as 1980 G.W.front and rear,.

Same thing on VintageCB750.In the pic for the rebuild kit it has o-rings for two pistons.Seems they dont have the correct pair of pistons for the rear caliper you have,though.

  DOES say 2 pc needed 4 80 F but not same piston 4 81 I guess.


   Check there part # else weres to be sure,
 There pics screwed me a couple times they make it right (sent right part after calling/same price)and know but don't fix pics.

DUDE! That site is awesome! I dont know why I couldnt find anything showing me a dual piston setup for my bike? The kit that you showed from CBsupply is what I was going to order but started questioning it when I looked in my clymers book and when they didnt offer pistons for the rear....I appreciate it shiny, looks like Im gonna order the pistons and what not through powersports. You had any experience with them?
