Hi all,

It seems like every time I replace any set of brakes that they squeak and squeal mercilessly. Not so much with my Supra (although they do sometimes), but mostly on my girlfriend's Camry. Over the years, I have done her brakes at least 3 different times, and they always always squeak. Just recently, I talked her into getting KVR pads with the assurances that they wouldn't squeak. Well, they squeak anyways. I left the OEM shims off, and used the red glue-goop that goes on the back of the pads. I've been told that this will positively prevent squeaks. No luck yet, though it's only been a week or so and I'm assuming (hoping!) that they're still breaking in.

Any thoughts on what I could be doing wrong here? I had the same problem with the brakes on her old Acura Legend, as well, so I'm not so sure it's a Camry thing.


Thanks for any advice, and sorry for the OT (I don't know who else to ask )

well one problem can be how you break in the pads when you install them with new rotors or turned rotors......it may be the way she drives. (ie you change em and she's right back to slamming the brake pedal to the floor). I can't remember the exact procedure....but another thing you could do is either but a new set of shims....pretty cheap....and slap them on or try both the shims and the goop...i dunno some suggestions...i know that i tried to get buy with some cheap pads but i can't they're sqeakin like crazy and my old shims rusted away.

No, I don't think it's that. I have told her the "correct" procedure, and I'm with her in the car at least half the time she's driving, so I know she at least tries to do it correctly. She's gonna take it real easy with the brakes the first few hundred miles, and then when that's done, we're gonna go out and do the 50 mph to 5 mph slowdowns, to heat cycle the rotors/pads. They've only been on the car for a week now, so we're not too far into it. She's even doing the "stop way back from stoplights and then inch forward" thing.

The goop is supposed to replace the shim kit, and is supposed to be used alone... I guess we could try goop on both sides of the shims, but that seems excessive. Who knows, if we get through with the break-in, and they still squeak, we'll probably try it.



thanks!

i dont know how much of that "goop" you put on the back of the brake pads but i tend to use a very generous amount on each of my pads, probably half a little packet you get at autozone on each pad, and i dont get any squeeks.

I used the red stuff that comes in a little squeeze bottle. Used quite a bit of it, really. Are you using the lubricant type, or the adhesive type? The lubricant stuff has always seemed like a bad idea to me - there's nothing keeping it from getting all runny and washing off onto your rotors... I used it on my Supra last time when I changed the pads, and I think that might be why my brakes are so less-than-impressive right now. No squeaks, though!

You can use anti-squeal between the pad and shim. Even anti-sieze works well.

Squealing brakes

I get the squealing from my brakes occasionally, and it makes me crazy! Well, crazier than normal! All I do to fix it is to take things apart and lube everything up. I put a dab of lube on the ends of the metal portion of the pads where they sit against the spring loaded clips that hold them in the bracket. You want them to be able to slide freely, or you will get squealing.
Another tip that a local Toyota mechanic gave me was that squealing can be caused by the razor sharp edge of the pad where the leading edge of the pad contacts the rotor. He said to just touch that part of the pad to a bench grinder or use a file to make that leading edge smoother/rounded and not a sharp 90 degree edge. Sure enough, that gets rid of the squealing. The problem is it only lasts for a while until that sharp 90 degree edge comes back after the pads wear down past the point where you rounded them off. Oh well, temporary sanity is better than nothing.
