so today i changed my rear wheel cylinder and shoes today.. everything was going fine. went to start bleeding the brakes right rear ok... left rear ok.. then i got to right front, oh and guess what its not the same size as the rear.. so im assuming its a 3/8, had to use a wrench with another wrench to get it to even budge. Got it to move barley to were it would open, bled it once, closed it and thats when it got rounded off. luckily its on close but i only got to do it once. didnt seem like it had any air in it, so i said screw it, went to the other side, bled it and it didnt have any air in it so i thought it was good. It seems to be fine, brakes are working ok, doesnt seem to be as tight as there were but it stops good. Now what do i do if i have to bleed the system again? how do i get that off or should i just buy a whole new caliper? also has anyone tried those speed bleeders? thanks
