Possible to save these caliper pistons?

[cj7jeep81]

Went to replace the pads on my rear brakes, and the pistons wouldn't compress. Decided to go ahead and rebuild the caliper. One piston came out fairly easily with compressed air, but had to fight the other one for a bit.

The piston that came out didn't look too terrible, but lots of rust/scale on the exposed part. The harder one looks a good bit worse. Any chance of saving these? I'm guessing not, just hate to have to order new ones, as it will probably be another week or so before I get the parts, and its getting really warm. But, at least I went ahead and replaced the rear brake line while I was in there.

If they were mine, I would get new ones

No chance - bin them before they kill you, or at best throw brake fluid all over your paint. And replace with stainless ones - they'll never need to be replaced again.

Even as cheap as I am, those would be ash trays.

where's a good place I can get them from? I've done some searching, and only found them at a few places, and don't know if they're stainless or not.

In the UK but I've had loads of caliper pistons from him:

They fit GS rear calipers as well (38mm x 23mm). Or get the cheaper RGV 250 ones that don't have the recess for the boot - being stainless you don't need to fit the boot anyway.

guess I'll give z1 a call, they don't show any on their website. was hoping to find a place that had them in stock. ordered some parts from boulevard last monday, and should be getting them this coming wednesday. also, are the oem ones stainless?

OEM are not stainless..which is why those look the way they do. Total trash..throw them as far as you can.

any vendors make stainless ones for these bikes like the ones linked above, that are in the US?

No (or so all the US guys tell me). Only over here where stainless is a must. Worth it.

Just a quick update. Ended up ordering 69100-08821 (piston set for rear caliper) from partshark, and ordered 69107-45000 (piston seal) as well, since some threads I read said it wasn't included, and I'd be mad to find out it wasn't included when it takes a week to get this stuff.

Turns out I did not need to buy the seal, and the piston set came with 2 pistons, 2 seals, 2 dust boots, and the seal between the halves. Got it all put back together yesterday, just need to bleed it now.

Thanks for reporting back! I think it does a lot of good for other folks to see a successful resolution to a problem.

I am a connoisseur of the finest twisty roads in Indiana, but I'll admit that I had to Google Osgood. You live in the midst of some very fine twisty roads, indeed. I'm sure I've been through Osgood at some point -- just didn't remember it.

Hope to see you in Brown County!

yeah, not much in Osgood to remember, that's for sure. But definitely some nice country roads. Been several years since I've been out to Brown County, but you never know.
