2007 C6 ceramic pads squeak when stopping at slow speeds. Installed about a month ago. Delco pads. Any suggestions?

 

mine squeeled since the day I bought it

 

Not properly bedded in.

 

Not bedded in correctly. Do a search. The Bed In procedure can be found with a quick search!

 

They need to be bedded in properly. If you havnt done it try this:

I bedded mine in properly and not a squeek in over 10K miles.

 

While I agree that you need to properly bed the pads, ceramics have been known to squeak and squeal forever. It is the nature of the beast - you can't use high performance pads and/or rotors and not expect them to make noise when cold. All cars have this problem - Ferrari, BMW, etc.

 

If the car had a lot of miles on it when the switch to ceramics was made, the rotors could have already been eaten by the original Made in Rumania pads, causing squeeks.

Try the bed in procedure as a first step.

 

i just did mine about 300 miles ago. bedded after about 100 miles... 5 to 6 stops (65 to 5+-) and just let them burn. no noise OR dust. we are very happy campers now .

 

You can try the bedding in process, but I don't believe it is necessary and you'll have to do it over again. Lots on here say this is normal, but thats BS to me. I don't normally hear Porches and BMWs squealing and lots on here have said their brakes have never squealed and they never bedded them in. And if it was normal, shouldn't all Corvettes make noise?

As for ceramics, I switched mine also and they initially were worse than the stock pads. Had my dealership chamfer all the edges and scuff up the rotors. 12,000 miles later, no squealing and I have never followed the bedding in process that others recommend.

 

A coupe of questions.
Who did the brake job?
What part of the country do you live in?
AC Delco ceramic pads are made by Raybestos. The same ones you get at Pep Boys. GM ceramic pads are made by Japan Brake. The same ones off the assembly line for the standard C6. The Z51 has semi metallic pads made by PBR a European manufacture. Almost all noise issues I see are cause by poor installations, not the friction materials. There are no harsh metals in a ceramic formulation unlike a semi metallic formulation. What I see are installers not using the shims provided by the manufacture. They don't use the lube for the backing plate. They don't lube the ends of the pads that rub in the caliper. They don't lube the sliding pins. They don't clean the rotors with soap and water. They don't dry the rotors off with paper towels. They don't tork the rotors all the same and to the right specifications. And we wonder why we hear noise.
As to where you live. If your area has moisture in the air and your rotors develop a little rust on them. Then you will hear some noise until that rust has been wiped away by a few braking actions.
As for the "bedding" process. As part of the manufacturing process the pads are burnished. This process already breaks in the pads. No OE wants to hear a noise complaint as the car leaves the lot. For the majority of the cases this process does the job. "Bedding" was needed when the manufacturing process do not completely "bake" the pads. Pads needed as much as 500 miles to fully develop. The bedding helped speed up that process. Pads are fully developed today when put on at the assembly line.
Now if I was going to use a true racing semi metallic pad then the "bedding" procedure makes sense. Those suppliers do not burnish their pads and advise their customers to do the bedding procedure. It is needed.
But hey I'm not trying to change anyone's habits. If you believe you need to "bed" your pads then continue. I'm just telling you what I know as an employee of a brake supplier.
One last note. Do not compare the Porsche and Ferrari ceramic braking system to any ceramic pads. Theirs is a total system with ceramic pads and rotors. Made to be used only for that application. They both make noise with the semi metallic pads or the new $13,000 ceramic system. Doesn't stop any better but saves almost 40 pounds of unsprung weight.
If you truely want to get the most out of your pads, buy the best tire you can afford. The tire determines how well you stop.

 

Got my Ceramic pads from GM Partshouse.... Installed them with 3000 miles on my 08 Vert because of the constant brake dust from the stock brake pads. I never "bedded" them... 3000 miles later no squeal and more importantly very little dust.
