Bleeding ABS

[Wesley.H]

So i changed a friends calipers after they locked up and ruined his brakes and rotors. I bled all the lines with new fluid.
But the ABS module must have air in it and i have no pedal. Does anybody have a scanner they would wanna rent out that is able to activate the abs? I realize the ones that are able to do this feature arent cheap but willing to work something out so its safe for the other person.

Also i live in Maysville GA if anybody is near and wants to make a few bucks coming by to do it real quick

Stupid question, and don't take offense, but are the calipers mounted so that the bleeder is on top?
I saw a guy do this on a gen 2 once. He accidentally mounted the calipers upside down putting the bleeder toward the bottom, making it impossible to bleed the air from the calipers. I don't know if it's even possible on the gen 4.

Also did you bleed all 4 corners? Many manufacturers separate the MC reservoir in opposite corners for safety reasons in the event of a blown brake line. So if for some reason you had air in the driver's front, you'd have to bleed the pass rear also. Again don't know if the gen 4 is this way, just throwing a few suggestions out there.

Ive never hear of anybody mounting them upside down hahaha.
I bled all lines 2 or 3 times from furthest to closest.

Believe it or not it happens more than you would think.
The only other suggestion i could offer is if you have access to a long gravel driveway or dirt road you can force the abs to cycle on its own by performing a few panic stops to lock up the wheels. After a few times you'll need to re bleed all 4 corners and likely repeat the whole process a few times. This of course is dependant on wether or not the truck can be safely driven and how far you have to go. Good luck with your repairs.
