Activate abs unit/brake bleeding

uisim · 03-20-2016, 05:35 PM

So I'm gonna bleed my brakes but just had a question or concern about this. I know how to bleed the brakes (I have a pressure bleeder)but let's say I get air into the system somehow.... I have a scan tool that can activate the abs motor for 5 seconds at a time. Would that be enough to get air out of the unit if I did that a few times? Also what would happen if I left one of the bleeders on one caliper open and I activated this?

If you have a pressure bleeder than by all means do this with the bleeder open. That'll move fluid through the system and any air along with it. I'd run the scan tool feature a number of times. (BTW: Which scan tool do you have?)

Just the Lill cheap schwabben from ecs. Something I can keep in the car or register a battery with. The main reason was for a battery.
Still working on getting NCS expert and all that working soon as my old laptop comes in. So... If I start with lets say the passenger rear caliper and I activate this abs motor a few times for 5 sec intervals and I do this for each wheel I can get the air out that way? Again I'm just curious I'm sure the pressure bleeder will work just fine I'm just messing with this tool. I ask because when I did this on a Evo the pedal actually pulsed and moved. This was with a snap on scan tool but it's old now and there's really not much I can do with it on this car.

Your bleeding plan is sound.
