2003 Sienna. Lately when ever I
back up, stop and then go foward, there is a "goan" from the rear of the vehicle. Sort of sounds like a burp. I assume it's something to do with the ABS and/or VSC adjusting. Question: is this a sign of wear? Is there some kind of maintenance to the ABS or VSC or the brakes themselves that should be looked into. I see that replacing the ABS brake pump and related parts is
VERY EXPENSIVE!!! 
The breaks have recently been adjusted, and I was told I had 75% pad left. Of course I also get the "Sienna Squeal"
from the rear brakes just before the vehicle stops. What I want to *avoid* is an expensive ABS repair if some type of maintenance is called for. I don't completely trust the Local Toyota dealer,
so any info would be very appreciated.
