When I went to buy my tracker 2 weeks ago, the test drive had a LOUD squeal when I first used the brakes. Didn't occur after that first time, and limited inspection showed pads looked like they weren't worn badly, and the rotors weren't grooved. I figured it would need som investigation, but wasn't too concerned.
Since I've had it, I noticed the squel twice, but I've not been driving it much since it's been in the shop (lift, etc). Started think maybe it was something getting corroded, and working loose ... perhaps a wheel bearing, hub, ...
Last night I finally got to pulling the wheels ... I now know where the squeal is coming from
drivers side ...

passenger side ...

Funny thing is pads look reasonably new, and yet those clips are worn BAD. Book doesn;t show these clips and the irony is I think they are actually some sort of "anti-squeal" clips ... LOL
