Hi
Is this normal that brand new FERODO brake pads are squeaking?
I cleaned rear brakes and they also start squeaking.

Here in Lithuania, at the car parts' shops we have a special membrane, which could be cut into pieces and you glue it to the other side of pads. They cost something like 3 USD per 10 sq cm. So, it's a cheap way to stop those pads squeaking

And it reaaaaaaaaaaalllly works.

They have all kind of stuff to stop the squeaking. They also have also some sort of paste that you put between the piston and the pad.
The goal is to absorb the vibration without decreasing the pressure on the pad.

Thanks guys you guide me. I googled and found solution:



I have to go to Mercedes Service and ask for this paste. It costs 1,2 Euro

I believe that the membrane would be a better solution as the pistons are hollow on the side of the pad.

I cant find this membrane in google (it does
not exist )

Thinking out loud... what about a thin plastic PET membrane like the one used in drink bottles. Can you cut a square from a flat packaging box that can be fitted between the piston and the brake pad.

Traditionally a stainless or copper shim is used but I have seen transparent ones.
You can try the PET shim and see if it cures it, then try ss or copper. I am sure that the brake specialist will have something that will fit or can be modified to fit.

Careful here men, remember, there can be considerable heat transferred from the pad through to the piston. PET may become melted under these circumstances, I suspect that's why metal such as copper is used. Probably doesn't pay to "experiment" too much around brakes.

Sure, I would only try it for a few km to see if this cures it and then proceed to cure the problem.

Moly paste may also be a good thing to try, but I suspect that any paste or grease would not last very long.

I bought this paste, (in Mercedes service - 1Euro for 2,5 ml ) and it works well... for now

This looks like aluminium temperature-resist paste
