ABS engageing for no reason

[nightime25]

After replacing all four calipers and bleeding correctly, all is good until I step on the brakes while driving then my ABS will engage. I'm lost as to why this is happening, is there a way to bleed the abs system or do you need to take it to a mechanic?

did you check the wheel speed sensors?

[batever]

one of your wheel speed sensors is messed up or missing, or somebody replaced your cv axle with a non abs one while you weren't looking.

the car is sensing improperly that the wheel with the messed up sensor is locked up, because the sensor is not sending a signal, making that wheel look like it is standing still (locked up) to the ABS computer, while the others still appear to it to be rotating. When the ABS computer sees this apparent difference in rotation speeds between the wheels it activates the ABS booster system, thus causing the abs to trigger every time you press the brakes.

you can remove the abs fuse to disable the abs until you fix it, or just live with abs braking 24 hours a day, which is probably just fine and is the way I'd go until I get the sensor fixed. At least the car won't lock up with the ABS constantly on.

I would be concerned about the ABS booster system not being specced out for constant activation. That would be my only concern about not deactivating the ABS in your case.

Do you know how to, and have you practiced, threshold brakeing properly without ABS? is one question I would ask myself before disabling the ABS though.
