[QUOTE="OX1, post: 15985423, member: 175132"] So an update on this. Never did get the Autoingenuity to work correctly to bleed the ABS. Discussed it with the guy who writes the code (and he supposedly worked for Ford for 15 years prior) and the best he could do for me was to tell me to manually input a 2015 escape, at which point I could run the ABS pump, but still not control any of the valves. My 14 was "really" left over, and we surmise Ford switched to a 15 CAN module on the ABS, late in the 14 Stang run. So I switched gears and got an Autel bi-directional scan tool for $1100. Unlike the Autoingenuity, it has an ABS bleed procedure (instead of just control of the pump and valves separately), which works fine. Ran this twice and re-bled, with no change. I have 30 days to return this, not sure if I will keep it or not. At least for that money, it will work on almost any car I or my extended family owns (Autoingenuity is much less money, but you have to buy each manufacturer seperately) Friend found online that when bleeding rear brakes, you should actuate emerg brake 5 times before bleeding. [URL='http://luxjo.supermotors.net/MUSTANG%20GT/BRAKES/BRAKE%20BLEEDING/IMG950189.jpg']http://luxjo.supermotors.net/MUSTANG.../IMG950189.jpg[/URL] [URL='http://luxjo.supermotors.net/MUSTANG%20GT/BRAKES/BRAKE%20BLEEDING/IMG950190.jpg']http://luxjo.supermotors.net/MUSTANG.../IMG950190.jpg[/URL] So I tried that, no difference. I also found a note in the 2011 Stang factory shop manual about MC damage if actuating it dry, but I'm 99% sure I never ran reservoir dry (hence I should not even be having this bleeding issue at all). So I turned my attention to the MC anyway, as it was suggested extended travel of MC could damage it internally (nothing about this in the factory shop manual bleed procedure, but who knows). I made two plugs to insert after removing brake lines and two fittings with lines to do a MC bleed, before trying the plugs. Removed master and bled on bench. Air came out on the first pump, about as much as would be in the empty return tubes, then no air at all. I don't think it had any air in it. Put original master back in, Bled twice and ran ABS bleed twice. I also found on the Autel tool a live data section and there must be a brake line pressure sensor somewhere, as I could read PSI and see it change as I pushed pedal. Car off, I can get about 900 PSI. Running, I can get upwards of 1700 PSI if I push really hard. Brakes do seem to work pretty good, it's just that pedal feels like it is on the floor and very spongy. With car off, I can get a really firm pedal after two pumps, and it does not bleed down, no matter how hard I push. I don't think it is a bad MC issue. I do think the master is just not large enough (for my preference of short/firm pedal travel). This is probably part of the reason ford swapped boosters to provide less boost. So I'm a couple grand into this Brembo swap now, and I really wish I had never touched the brakes. The stock brakes were pretty horrible, I even had it at the dealer for them to bleed them (as I felt even new they had too much pedal travel), but they told me that is the way they are and many others have confirmed the stock brakes are really not all that great. Interesting that Ford uses the same MC on all 15+ stangs (cept 6 pistons). [URL='https://www.tascaparts.com/oem-parts/ford-ford-mustang-master-cylinder-fr3z2140c?origin=pla&gclid=CjwKCAjwkrrbBRB9EiwAhlN8_EyWEaeROo29tBRr9aoZF_fOW_QsewLWFIGMDC-SQjds_86B7vNB-hoCJvsQAvD_BwE']https://www.tascaparts.com/oem-parts...hoCJvsQAvD_BwE[/URL] and the stock GT 4 pistons that come on 15+, are monsters compared to the 14 and down brembos. [URL='http://luxjo.supermotors.net/MUSTANG%20GT/BRAKES/BREMBOS%20FRONT/2015%20MUSTANG%20BRAKES/IMG_1562.JPG']http://luxjo.supermotors.net/MUSTANG...S/IMG_1562.JPG[/URL] Point being, that the difference between 2 piston caliper area, (15 up V6, which uses 14 down GT 2 piston) and and 15 up GT 4 piston is an even bigger jump, yet Ford still uses same MC on all 15's but the 6 pistons (which uses a 1-1/8 vs 1-1/16).
