brake bleeding firm now spongie.

:banghead: okay.... like I've posted (not trying to sound like an asshole) the bleeder screws are at the top, I bench bled the mc mounted in a vice with a bleeder kit with the hoses submerged in fluid and pushed the piston (not complete full Stokes) till there was no more air and good fluid transfer. Installed the mc with the plugs back in then hooked the lines up and started bleeding farthest from the mc first. I think the problem was I was putting the caps back on and causeing massive vacuum in the mc Res.
Not the caps. You couldn't put them back in fast enough to lock a vacuum in the m/c & it would be gone in the time it took you to attach the lines. I bleed them all the time that way & its fine. If it only occurs after you bleed that one wheel I'd think it would have to be isolated to that part of the circuit. Bleed it to where you get it to act up, then pinch off the hose to that caliper & see if it improves. Release it & see if its spongy again. If so, problem is in that caliper. If not move farther up the circuit. Check, check & recheck all the fittings involved. Have a helper hold pressure on the pedal & go around & look for leaks.
