This is more to confirm I've been a dur-brain.
Got some Rebas off here and was just setting them up for me yesterday after fitting to a bike I'm slowly building up. So, emptied out both -ve and +ve chambers and then proceeded to pump up the -ve side to around 100psi. There was a pop sound at about 80 or 90psi and I thought "Ooh, I wonder what that was?" (See, dur-brain - )
Flipped it over and filled the +ve side and as I got to around 80psi the pump gauge would drop back in pressure.
So, can someone confirm my suspicion that I've popped the seal between the positive and negative sides? And, yes, I know, I should have filled the positive side first and if I'd bothered to wait 2 minutes I could have worked it out.
What prognosis then? Got to send a shock to LoCo this week, so looks like he's probably getting some Rebas too.
