Ceramic Brakes are squeaking

[camaronat]

Can you guys help me out?

Yesterday, I put slotted rotors and ceramic pads. While I was breaking them in, they started to squeak. Now they make noise unless I get on them until they are hot. This includes just driving down the highway.

Any ideas?

Sorry, didn't put the question in there.

How can I fix this? Does the entire hieght of the pad need to ba chamfered?

[slow6]

did you use anti-brake squeal grease?

well slotted brakes do make a sound... its just the pad going over the slot... the shouldn't squeek though just a air sound i was talking about

thats wierd, ceramic brake pads are suppose to be silent.

i would have to say it is your rotors, my dad has them on his car, and they have been silent for the past 2 years.

ceramic pads will always squeak. I had them on mine for 1 day, the next day i changed to organic.

[camaronat]

Yes, I put the antisqueal on them. So that shouldn't be the problem.

Hmm...I'm not sure what to believe about ceramics being silent. From what I can tell, it can go both ways.

Could my rotors need to be shimmed? That was the only thing that I could think of today.

switch to new organic brakes, if squeak goes away, you will know. I doubt your rotors need to be shimmed, were your old brakes squeaky?

I've had ceramic brakes on my car for over three years now and never even heard them make a single chirp...ever! They are completely silent, and almost zero dust. I wouldn't buy anything other than ceramic brakes for any of my cars. I've even put them on my wifes Malibu and my Honda Odyssey, and don't have any complaints.
Maybe it's the brand of pads you went with...? I bought Ceramix Brand for my Camaro and CarQuest Ceramic Pads for my other two cars.

Have you bedded them in yet?

Ceramics exist for two reasons: not to dust things up as badly, and to be quiet. I have no noise with mine either, but I did the installs very carefully [cleaned well, used a hardware kit, used anti squeak goop, and torqued things down pretty correctly].

High performance parts often function well when pushed to extremes, but are less nice to live with day to day.

BTW, my ceramic rear pads had shims built into them. I can't remember whether the fronts did also.

I use ceramics because I dont want the dust staining and degrading my polished aluminum rims.
(which already happened with the stocks)

Can you bed in the brakes at any time? Like after 15k miles?

I guess so, it's best to do it when they're new though.

I did try breaking them in, but didn't follow that exact format. I am gonna try going out and bedding them a second time, to see if that will fix it.


The weird thing about the noise is that it only seems to happen when the brakes are cool. If I am on them hard, they are silent. But they are noisy as hell just driving around.

Well, off to wear down my brakes some. Wish me luck.

My hawk pads squeaked like friggen hell when I put them on. I bedded them once, and it helped a lot, but it still squeals some. I need to go bed one more time.
