1997 LX450. 131K Got an intermittent whirring/moaning sound coming from the front when braking.
Definitely NOT the typical high pitched squealing from the pad wear indicators.
Has been happening on and off for the last 3-4 weeks. Noticeably, when actually braking to a stop vs. just braking at highway speeds to slow down. Mainly at 40mph and slower - coming to a stop. No whining or whirring during turns.
Did it on my way home today. SO I actually sped up from a stop and then braked hard. No noise. Sped up from a stop and applied steady brake pressure and I got the moaning noise. After a few hard brake attempts - it went away again.
It is also not a constant noise. Meaning when you apply brake pressure it is a split err-err / normal / err-err / normal / err-err. As if it is only at certain points during tiring rotation??
I did search the FAQ - mostly what I found was issues during turns, birf clicking sounds, or increasing whining as you speed up, etc. None of which seem to match what I have going on.
Suggestions on what to look for?
Warped rotors? Stuck caliper? Need new pads?
