Resteal gone bad, when to fire second barrel? 5/10

[sapster]

I had been pretty quiet and have not been at table too long. Button active player not too much of a read makes it 30 and I feel like I should take advantage of my image, I raise to 105 with ah6d from the sb, effective stacks 1k.

** Dealing Flop ** [ Jd, 5d, 6c ]
I lead 135 on flop and am just called, should I give up here? It seems as thought if he was slowplaying a big pair and is not afraid of me, i.e AA hed want to get it in now or if he has a set he'd probably raise as well figuring to get it allin vs me. Who fires a second barrel and does this change depending on the turn card, and who just gives up and why, what range do you think the average 5/10 party player can have here?
