MC Swap with ABS?

[Joethefallen23]

Swapping the 3G MC and BB is a popular option for better feel with bigger calipers as we all know. I should know, I've done it myself. My question is, how does one go about bleeding the system after swapping the 3G MC into and ABS equipped car? Surely air is going to get trapped in the ABS pump? My buddy is looking to do this but he DDs his GST and wants to keep his ABS. Would I be correct in assuming the only way to do this without, say a MUT Scanner, is to bleed the brakes initially and do some hard braking to cycle the ABS pump then repeat the bleed?

Anybody have a clue?

I have been wondering this myself, so I hope someone has some info.

Bleeding ABS Brake Systems

I'd bleed as normal (also pre-bleed the master cylinder prior to installation) but I think you're going to be okay if you cycle through, activate the ABS a few times, and rebleed.

Assuming I read the link right, the ABS pump is a closed system until activated? Honestly enough, I don't understand necessarily how the pump itself functions but it does make sense to separate the pump from the main braking circuit until necessary. Thanks a bunch. I'll have him cycle the ABS regardless and do a re-bleed to be sure as can be. Thanks Cait!
