Brakes, Calipers and Rotor "Problem" for 2001 Z24 Cavalier?

My car has had a strange low "wooing" sound since October 2007. I've been to three different places with three different opinions:





(1) need a new wheel barring (replaced and paid $300.. noise is still there)


(2) need four new tires -- the noise is "tire noise"


(3) Anti-lock Brake System needs major repair





We definitely need new brakes, but apparently the noise is a result of the rotors and something being completely destroyed.





We were told that the car doesn't have any front brakes and is extremely dangerous to drive right now. It is stopping with the rear brakes. Obviously it's not safe to drive without brakes, but if this is the true problem, we have been driving the car for 2 1/2 months. I'm freaking out because I just had a baby 10 days ago and don't want to take any risks.





We were quoted a minimum of $500.





How legit does this sound? Has anyone had this problem before? Advice?|||I would rule out the anti-lock problem unless the anti-lock brake light on the dash is on and I have still never heard an anti-lock brake system make any noises like that, are you sure they replaced the right wheel bearing?, the other side could have been bad all along and finally if you need new brake pads I would get them put on and 2 new rotors as those rotors are really cheap to buy at the parts store, like $18 each.|||The front brake pads have little metal peaces that will rub against the brake rotors when the pads wear down. since you have had the same brake pads on the car for SIX YEARS than this tells me that you are in Dyer need of a brake job. I would have new front rotors and pads installed and new rear drums and pads installed. If your tires where making this noise than they would be bald they would have no tread on them at all. If the well bearing was bad than you would only hear it on one side. Also when the mechanic that "fixed" the wheel bearing was working on your car he should have examined the brakes any ways and told you what the car needed.|||well alright i had a situation were the peice of the metal that held the brake pad in place stuck out and made a loud sound when ever i moved my car it was very noticeable and it was just a little peice of metal that i took off it sounds like thats what it is|||that wooing noise maybe a roaring sound? , to me could sound like a wheel bearing,i guess he thought so too,its just strange that you need to remove the brakes to change the wheel bearing and he said nothing about them, if they were that bad it should have been obvious,how does the car stop? if you are only stopping on your back brakes it is going to take longer to stop, enough to where you should notice a difference. take it somewhere else get a second opinion, something does not sound right|||Revisit that "fixed" hub bearing,cause it sounds like your mech. may have put on a used bearing. As far as the brakes,you will definitely need new pads and rotors,and before anyone does the job,find a reputable service center to do a thorough check,including the wheel bearing assemblies.


Now,even though $500.00 sounds steep,as long as a reputable shop does the job,then safety and quality will not be an issue.
