W111 220s brake parts help.

[s883231]

Hi,

Peach parts members

I am from Taiwan

I have a 1963 w111 mercedes 220s and it is loosing brake power.

My mechanic showed me the rubber parts in my photos that needs replacing, can anyone advise me what is this part called ? or where I can find a rebuild kit? It is located near the master cylinder.
kind regards

That big cast iron part appears to be the interior part of the brake booster. I am not sure you would need a new one of those since that one looks OK in the photo. This is the part that attaches to the brake booster and allows it to be bolted to the car. The part number for this is 110 430 00 45.

The rest looks like the insides of the master cylinder. These are ATE parts and the ATE part number is 3.0370-0917.2. The going price for one of these kits is in the $150 range so make sure this is what you need before ordering one.

If this info is not correct then it is at least a good place to start from.
