A PCCB break pad question

[slawus]

Can anyone tell me please what is the purpose of the thin metal plate that seat between the dampers and back of the break pad? Is it necessary to keep it there? When I did the breaks on my Mercedes ML63 which also use Brambo breaks I was told to remove them because they are often the reason for the breaks to squeak. I have the PCCB on my car and I’m not sure if this information also applies.

They are vibration dampers and Porsche recommends they stay in place and are replaced when replacing pads.

Yes, the dampers sit in the pistons, they are attached with adhesive to thin metal plate and then the break pad sit in the thin metal plate. My question is, can I attach the break pad directly to the dampers without the thin metal plate in between? Thank you

No, if you do that, squealing will be the result, the metal plate is also performed as a heat shield. The separate dampers come loose from the pads by heat if they are directly connected.

Thanks RFM I’ve received the pads today they have adhesive on the back of the thin metal plate, as well as on the back of the dampers Do you recommend to put some paste s between the thin metal plate and the pad?. Funny think is that nobody at the dealership could tell me if the are any dampers on the rear brakes. The part number book doesn’t show any dampers for the rear brakes.

There is (was) no recommendation to use paste between the plate and the pad, as far as i can remember.

Ok. So I did my front brakes today it was an easy job, I spend most of the time on cleaning of the silicone from the pistons on the inside of calipers. Imagine my surprise when I discover that there were no dampers, but instead some type of silicon that was use to hold the pads and most of it already loose. Anyway put the new dampers in, use special paste between the thin metal plate (heat shield) and back of the pads. Drove the car and now everything is very quiet and back to normal.

Oh I forgot to tell you guys that my wonderful dealer in NYC. quoted me over $3000 + parts for the front and rear brakes job.

Tomorrow I’m doing the rear ones

Thanks for all your help. .
