'94 R1100GS - rear brake pistons?

[MMC]

And here's another brake question...

Anyone know where I can track down replacement pistons for the rear caliper on my 1100? Motobins/Works/BMW main dealer all coming up with "You need to buy a whole caliper, sir." I can get the seals OK but not the pistons. I suspect something, somewhere must use the same pistons as the 1100!

The bike's a '94 GS with a Brembo two-pot on the back

Thanks

The answer is, in fact, find the old caliper in your Box of Bits, take it to your pal who runs a garage and get him to drive out the pistons with his compressed air gun.

Assuming of course that the pistons in said old caliper are in good and useable condition.

Begging the question of why it's an old caliper in a box of bits.
