Well I had to take my sled to the dealer Sat morning for some electrical issues. When I was sitting at a light, I felt a thud in my brake pedal. It reminded me of what you hear when you turn defroster on. But this was in the pedal. I didnt notice any difference in brake performance or anything... I can’t recall noticing it in the past 9 months I’ve had the truck.
I didnt think to check brake fluid or anything, as everything was working fine, and it was snowin& blowin nicely...And has worked fine since, just curious as what it might have been...

Not sure if it applies to our trucks but my ZJ did that on occasion and it is the ABS cycling itself in a test mode in the jeep anyway. Could be that our trucks do the same thing?

Yea, i dont know...the only thing i could think off was a pump kicking itself on or off....but dont know what..

Just thought id add that oddly enough today i felt a similar thud in the go pedal....odd....
