Ive taken my corroded 500 calipers apart to rebuild them, and in each, the pistons are two different sizes. Is this right?
The rebuild kit that came from NLM has 2 identical sized o-ring seals, whereas the seals are of course different sizes aht have come out of the calipers, meaning I can only renew one
What's going on???!!!

For the benefit of those not on the email list;

No it's not right, you'd get a different force from each piston, trying to push the disc/caliper sideways.

What's going on?

You tell me, you're the one there and it's your bike.

My 500 has Brembo F05's with 32mm pistons (one each side so 2 per caliper) and it has 94mm centres from mounting bolt to mounting bolt.

So Morini boy do you have a name? I prefer to deal with people rather than fictional aliases.

My name is Rod.
