Is this normal with Hayes?

I left one of my bikes upside down for 2 weeks, and today I took her for a ride and the front brake sucks. You can pull the lever till the bar and it wont brake.
I noticed that that little hole was without ink around it, probably because DOT fluid came out. So is this normal if you leave the bike upside down?

Curious is that the rear brake doesn´t has this problem.

you may have had air in your system to begin with. It can sometimes take weeks for the air to move out of the system. If you have a leaky bleed nipple, try using teflon tape to stop it...

I didn´t meant the bleed nipple on the caliper, nor that bleed screw on the lever, it´s that small hole on the inside part of the leve.

is a sort of pressure release valve. IT allow some out if there is too much pressure in the system. I think it was probably just air in your system...

That'll happen if you have air in the system. You simply need to bleed it again.
