Hello from Sweden!

I have a Huracan LP610-4 and have some questions about the brakes that squeaks alot. I have earlier replaced the front pads and now it squeaks from the rear brakes. I have had the brakes apart two times and mounted it with "Brembo B-quiet" and the last time the rear brakes were absolutely quiet, for 200 km and then the squeaks were back again when braking.

I know many people tells me to do some hard braking stops every time you drive but it doesn't help and the squeak is still there. I know this is a common problem with ceramic brakes but they haven't been like this all the time.

My question is if you think I can fix this by replacing the rear pads that is the one squeaking at the moment? The pads look like new but I think I will change them anyway if I get rid of the sound, but I don't want to pay for new rear pads if they also will squeak after a while. Anyone know what to do and if new pads will solve the problem? Or do I have to live with it?
