Hallo!
I compared brake booster (Bremskraftverstärker) from my P7 with the b.b. Mercedes W601 (MB 207D, same in W115?).
They proved to be very similar. I would want to purchase new b.b., but thus far found only "replica's (oldcars.de)”.
In my view, the replica's even is worse than new amplifier for Mercedes.
Who dealt with this problem, prompt, as you solved it.
Brake system P7 have same parts with from MB, BMW, Talbot of the same time period.
One different between P7 b.b. & MB W601: b.b. from MB too thicker than P7 b.b.
Also I see some similar b.b. on old BMW's.
Main brake cylinder, rear wheel cylinders and metal tubes same on a BMW's.
Front brake calipers same on a Talbot.
Rear brake pads same as rear brake pads on a MB W123. Also rubber tubes same on MB's.
Brake booster fastening flanges same on MB W601 (& may be W115).
May be you think identical b.b. to P7 from another car?
Please, help me with my problem with brake booster. I can't drive car w/o brakes booster :D
dank.
