Brakes 93 400 SEL (w140)

[pilot2000]

I recently did the brakes on my car, installed new rotors, new pads, and sensors front and back.

And after the work was completed I hear a very ear piercing squealing noise from the front brakes, I don't hear it when the car is cold and I just rolled off the driveway, only a few blocks after. and I also don't hear it if I just tap the brakes slightly and give the car time to slow down.

Any ideas?

I have used the silicone-based lubricant that came with the disks and also dismantled the brakes a week later and used the Brake Quite (like paint) lubricant as well.

Thanks in advance
