I have only had my new to me 06 MMH out on the road a few times seance I redid the AC so I'm new to quite a few things with these. This one jumps out at me first. I know the ABS brakes pump there selves up after its been sitting and the door is opened but is it normal for them to randomly pump up while driving?

 

Hopefully random pumping during driving is normal because mine still does it while driving and not just when the door is opened. So far the brakes seem fine.

 

It can at times, especially if you just used the brakes and it activated abs. Are we talking once or twice or is it going off every ten minutes?

 

It varies, I don't notice it as much while driving. More like while at stops. I will try and listen for its time pattern during next drive.
