On my wife's 2012 Scion xB (43,xxx miles on original pads), over the past few weeks I have occasionally noticed an odd noise when braking.
It almost sounds like grinding, but not quite, maybe more of a grumble, but I don't feel anything.
It is not all the time, and I cannot replicate it regularly.
It is only when stopping and while at slow speed, seems to only happen when going straight.
As soon as I let off the brakes, it stops, and does not start when reapplied.
I have pulled all 4 tires, saw nothing abnormal, probably 1/2 pads still there. Fluid is about 2 years old (DOT 4) and is clear.
Today pulled all the pads. Again, nothing looked abnormal. Rotors look fine.
I did lightly scuff the pads with some 400 grit paper before putting them back on.
Any idea what else to look at?
Would bad CV joints do this? They seem fine, boots intact, no noise when turning.
All suspension seems fine.
I thought possibly the transmission is making some weird downshift, but don't think so (drain and fill @ 30,000 miles with Maxlife ATF, fluid still looks red).
If it was the transmission, it would not stop when I let off the brakes, right?
I have some new pads in my cart right now (Akebono ProACT front and rear) and debating just swapping pads and see what happens. Or is that just a waste of $100?
