Thanks for the link Hedge. Yeah I'd say those are our calipers:
30/34 Al Left 40mm Bolt Center - Brembo
Looks like 30/34 to me. I'm pretty sure I would have noticed a leaking caliper, I usually bleed my clutch and brake lines every year to clear out the old fluid, but I'll double check 'em when I install the new pads and rotors. BTW the new rotors are much thicker than the stockers, and lighter than I would have expected too. I'll have to compare to the stock ones.
