Carbon Ceramic Squeak....

#42
Update: Brakes are back to screaming as loud as ever. Taking the front OEM pads off and will save them for dedicated track use. Looking at other pad options that will strictly be for street use. Anyone have recommendations beyond Carbontech 1521's? Don't care about dust, just want them to be quiet and not ruin the carbon ceramic rotors.

Are the Carbotech 1521s going to work with your ceramic rotors? They were designed to work with iron rotors not ceramics. The pads for the ceramic brakes are made by Pagid and when you look up pad information on their web site you will see they make pads that designed for ceramic rotors. I wouldn't worry about the squeal. With the windows closed, the AC on and radio on you can't hear them squeal anyways.

2: Have you followed the street burnishing procedure?
3: Have you at least done some high speed stops simultaneously?

2: Have you followed the street burnishing procedure? (multiple times - only a temp fix)
3: Have you at least done some high speed stops simultaneously? (yes, that is how they were burnished and that procedure is what made these so damn loud in the first place - they were fine until then)

Tort,
Have you tried the Disc Brake Quiet again at all? I've used it on everything for years with good results. Since you said you used a thin coat I may pull the pads this weekend and put a heavier coat on them. When you pulled the pads after the DBQ quit working was there evidence that there was metal to metal contact between the backing pads and the caliper? Every time I've had to go back in and refresh the DBQ material I've found metal on metal wear points. Once I reapplied the DBQ the squeal went away. Not ideal but it worked. I've even had to tweak hardware at times to ensure everything was sorta tight yet slid smoothly.

The high temp ceramic paste I posted about earlier in this thread has solved my squeal 95%. The noise they make now is tolerable, where before it was unacceptable, sounded like a taxi or Metro Bus

I've been unable to find any definitive information about the nature of the squeal. Is it pad on rotor or is it backing plate on caliper? I've come across some info about beveling the edges of the pad which indicates it might be pad on rotor. I'll pull it down this weekend and take a look.
There's got to be a fix for this....

Bumping an old thread but I'm ready to trade this car in....... tried brake grease, stop squeal, cleaning the rotors, just last week tried copper high temp stuff on it, burnishing. None of it works, the car is silent first 30 miles of driving then it's bus size squeals at every stop. I have also followed threads of new oem brake pads not correcting it either.
Willing to try this 1521 pads if they actually work. Anyone have updates?

For what it's worth over the past few years I found that hitting the rotors lightly with my small pressure washer and just water works the best. It's a pain but if I'm careful I can save wiping down the car and do just the wheels. It seems to last for about 50 to 100 miles or until they get dusty or hit dirty water again.

Same here. After about 50 miles I get a squeal. Blasting a garden hose between the rotor and pad will rid you of it.

I have now tried all of these so no matter what people say on the forums don't waste your money. Squeal is still there after a long day of driving. It's not a vibration squeal, more like friction squeal.
