Brake system noise
Chevy Express 4500 van chassis. This morning first thing, backing up to leave camp, when I applied the brakes, there was quite a growl. It varied in intensity. It persisted after we came to a stop. It sounded like a pump or bearing going bad. By the time I got down to the campground entrance, I had figured out it was to do with the brakes. Press on the pedal, get noise. Release the pedal, in a moment or two the noise would stop. Moving or not, so it's not the actual brakes or bearings.
By the time we got into town, no noise, can't make it happen again. Now we have driven all day, no more noise. Fluid level is good. MH has 20K miles or so.
ABS pump, I am thinking. What, why, etc.?? Is the pump driven electrically? If this doesn't re-occur, I'm driving it another 500-ish miles in the next couple of days, and then to the dealer.
