Nothing wrong with new padsJust got back from the dealer. Service manager told me that he may have to replace the brake pads. Hope this fixes the problem. He wasn't aware of the service bulletin.
marmar, it reads like you will get your C7 squared away, good deal. That is one reason I like this forum so much, outstanding members sharing knowledge!! I've learned more from forum members than any book or magazine could teach me. So the knowledge I've learned from fellow Vette owners, I also can pass it down to future Vette owners.Just got back from the dealer.

This was my experiance, FWIW. Treated my brakes as recommended for break-in. At perhaps 1000 miles they periodically squeeled like a stuck pig on slow speed stops. Was very loud. Following some forum advise and some prior experiance with other cars, bedded the brakes. (You can google to see what that is about, but especially for high performance pads you need to get some pad material uniformly on the rotors. That is accomplished by heating the pads near their max operating temperature and then allow them to slow cool.)I have a 2015 Z51 3LT with 2600 miles. I have had the flex plate and torque tube replaced as well as the roof pins. Just yesterday the brakes started squealing as you come to a slow stop. It is doing it intermittently.
the dealer wants to replace them so they can get money from GM for the easy cake job work done to replace them. $$$$$ cha ching $$$$$$Bedding pads is more important than most realize, and then performance pads can still be noisy. Most now chamber the leading edges and have anti-squeal material between the caliper and rotor to absorb the resonance that you here. May be as simple as a glaze on the rotors that needs to be cut. The dealer should ALWAYS be aware of TSB's....they can pull them all up with a few key strokes. Any with a good competent service department, especially those that service the C7 should be aware.
I agree, dealers get paid to put grease on the pad edges or replace them with warrety money from GM. A number of folks have said it only lasts a short time and comes back! Recently read with performance pads you need to periodically use the brakes aggressively to keep a uniform friction surface on the rotors. I have a few 90 degree stops where do use high "g" force stops before turning.the dealer wants to replace them so they can get money from GM for the easy cake job work done to replace them. $$$$$ cha ching $$$$$$
ln theory, guess you could get the rotors up to temperature that way. Also assume some pad material would transfer to them when they are hot. But would it be the same as hard contact? I assume the bulk of the pad transfer would occur on the last few stops of the normal procedure.So, here is something I have done on another car to bed the brakes. Does anyone (Mark, Jerry, others) see a problem with doing this?
Instead of breaking hard like all of the brake pad bedding instructions say, just drive down the road at a constant speed (in the 35-50 MPH range) and apply the brake about 10-15% with the left foot while maintaining a little more gas with the right foot to keep the speed up. Do this for a minute or so with the window rolled down and only release the brake after the brakes start to smell. Then drive normally (55 MPH) for 15 minutes or so without using the brakes to let them cool.
Isn't this better than the standard bedding instructions? It lets people maintain a safer driving environment instead of rapidly decelerating over and over, it seems to me as if it would not be as hard on the brake lines, and it is easier than trying to count "How many times have I done this, and how many more do I need to do?"
Mechanically-knowledgeable guys, what am I missing here?
Exactly my experience too. Only while backing out of the driveway in the morning or after it's sat for most of the day at work. A little aggressive braking got rid of it.I have the non z brakes. Early summer I experienced squeeling brakes while backing out of garage after sitting over night. I happened to take my gkids on a little autocross in a school parking lot-- going fast a d then applying brakes really hard. Problem solved! I'll see what happens after the winter rest.
