    so after searching i find that some may have had to send truck to shop to cycle ABS module to bleed front brake line from master through line lock to ABS module. Others just say that they did gravity or vacuum bleed like a traditional brake system and act like all the air in the new lines from master to ABS module magically got out

    or……...

    You can cycle the module by putting the system into antilock. Obviously you want to do it in a safe environment like a deserted parking lot.

    30+ mph right? i was wondering if it would activate based on speed or pedal pressure and if the compressed air in the line would mess with the pedal pressure to the point that it wouldn't activate to cycle motor

    You will have to run around 40 or faster then hit the hooks hard enough to engage the antilock system. That should tell you if all the air is out of the module. Except the pedal to drop if any air is purged. Then I would give all 4 corners another bleed.

    everything seems ok after the run and stomp and bleed

    on a side note, ran across a guy who says he had one several years ago and after he put the line lock in the ABS motor started leaking from the little black rubber "buttons" under the brake lines. he said that is where the blow out is if the system gets too much pressure from the lock being engaged. said he had to re-route the line lock AFTER the ABS motor. never heard of this and I've seen a lot of systems plumbed this way, thats why the bracket was built this way

    anybody know about the ABS motor??

    Never heard such a thing. The ABS module is not like a boiler tank or gas cylinder with a blow off valve. The brake line or fitting above was probably leaking.
    Also the ABS module is similar to a line lock kit. It holds, dumps or applies fluid pressure to the calipers. That keeps the wheel turning during a panic stop.

    thats what i told the guy, the external line lock doesn't increase pressure, it just holds it like the ABS like you said. guess i won't worry about it until it happens
