Replaced the rotors and pads a few weeks ago and started to notice they are squealing at low speeds. This weekend I removed the pads and applied the anti squealing lubricant to the back of the pads (shims) and reinstalled them and they still squeal. The pads are also ceramic

Pads should be softer than the rotors. That's why you measure the pads and replace them when they wear out. If the Pads are harder than the rotors then you are going to get the noise. If the pads are harder than the rotors, the pads are wearing out the rotors. Its suppose to be the other way around.

The pads were worn out and need to be replaced and I also installed new rotors. How does measuring the pad thickness determine the hardness of the material?

I SAID YOUR PADS ARE HARDER THAN YOUR ROTORS ! Ceramic pads are hard if there is too much ceramic in the pad compound, they will be harder than the rotors. Pads are suppose to break down when you apply the brakes, that's why they wear out. If you buy into hard ceramic pads because they don't dust, their hardness can easily effect the rotors.
measuring pad thickness has nothing to do with pad hardness. Pad thickness is measured for safety compliance. " They " are suppose to wear out. The softer the pad, the higher the friction rate is. IM not going to get on this ceramics horse again.

Ok you don't have to yell! re read your previous post you did not " My pads were harder then my rotors" you actually said "Pads should be harder than the rotors, that's why you measure the pads and replace them when they wear out"

Read it again are you dyslexic?
here is the post I made and the post you quoted

Never mind, I have no idea why your brakes are making noise, Im real new to this forum and have no idea what IM talking about.

What ET is telling you is that ceramic pads are very hard and don't dust as much because of it. They heat up the rotors more and also wear them out quicker. Since they are ceramics, they could be squealing on the rotors. ET is one of the smartest guys on hear and very passionate if you couldn't tell. He knows what he is talking about. You may want to try different non ceramic pads.
