New here, Ive searched and read posts until my eyes bleed. I bought a banshee from a friend and he didnt have the rear brake system mounted, Ive got it all mounted and have bleed it using a syringe and tube, but it keeps sucking air bubbles out of the system and the brake lever never gets stiffer. So my question is, can I be sucking air through the caliper and would a rebuild kit fix this issue. The next question is I dont know if its a stock axle, but when i press the brake lever the piston/pad move out and push the disc, shouldnt the disc get pinched and not pushed to the other pad?
