The bleeder screw is leaking at the thread on the right side caliper, what can I do to fix this? It is only a little bit but I don't need it to leak at all, as far as I know the bleeder screw is tight,I got all the air out already and I don't want to do it again. what ever you guys tell me to do will I need to bleed the whole system again? thanks

 

The bleeders don't seal on the threads they seal on the tip of the screw against the inside of caliper. One of those surfaces must be messed up-hopefully the screw not the caliper. Buy a new one and see what happens.
