Here's a weird one...
So while replacing the pads, the bleed screw on the right front caliper twisted and destroyed the threads on that caliper. So I replaced that caliper and while using my MityVac, I ran the reservoir dry. Nice.
So, filled it up, bled that side, got the air out, and I can move the caliper towards and away from the chassis by about 1mm, and the rotor spins free, which means the piston has not moved and it has no pressure.
I bled some more, then my MityVac's internal seal broke and shot brake fluid all over me when I pulled the trigger. Great. Now, made a pressure bleeder from a bike pump and other bits, and pressure bled that caliper. Still no more air, and no pressure at that caliper. WTF.
I gave it a few days to let the car think about what anxiety it's causing me, to which it couldn't have cared less, and hit it again today. This time I bled the front right caliper and got a little bit of air out after pushing through maybe 1/4 pint, and then all seemed good as far as air goes. Bled the "trouble" side again, and no go. Still no freakin' pressure!
I know this system is separated from front to rear, so I haven't touched the rear (didn't do those pads anyway) and that little portion of the reservoir is at max anyway and has never dropped. What I'm fearing is that there is some air stuck in the ABS pump, but if there was, how would I get a hard actuation of the front left caliper and none at the right, and no air coming out either side?
I have bled well over a quart of fluid through the system now.
Should I put a piece of wood between the seat and the brake pedal, depressing it, and bleed again with the ignition turned to on to open the ABS circuit? Would that even work?
HELP! AAAHHHH!!!!
