No brake fluid at the caliper?

The brake fluid reservoir will take 2 bar if its not cracked or damaged. It'll expand quite alarmingly, but I haven't had a D2 one pop yet! You'll not push fluid through the ABS pump at 10psi.

I really hope it's not the master.

OK I'll take the risk and go to 30psi tomorrow. Should I have all 4 calipers open or?
