I recently acquired a 1965 Chrysler New Yorker, and I'm going through the brake system (four wheel drum). I've cleaned up and flushed the master cylinder, and it seems to be in working order, but I would like to replace the seemingly paper diaphragm. Maybe I'm not looking hard enough on Google, but I can't find anything on it. Thanks for your input!

 

Are you talking about the diaphragm in the power brake booster? You can get a whole booster from rockauto.com for not much money.

 

I'm talking about the piece that goes in-between the master cylinder reservoir and the cover. In newer cars it's like a rubber that expands to adjust to lowering brake fluid levels, but in this car it seems to be a paper element of sorts.

 

Might be easier to just replace the whole master cylinder. They are available and probably updated a little in design. With an old car like that you can't be sure that what you are looking at isn't something that somebody cobbled up.

 

i'M SORRY TO JUMP IN HERE BUT I'VE LOOKED FOR 30 MINUTES- HOW DO YOU START A POST?

 

First, make sure you are in the correct forum. This is the "General Tech" forum. If your post relates to a particular car model, go to that area to post a question. Before you post anything, search the forum to see if your question has already been answered. If not, look for the "New Thread" button at the bottom of the list of threads on the front page of the particular forum. When starting a new thread, give it a name that will describe the problem so it will be useful for others with the same problem. Names like "Help me, please!" are not useful. "Heater doesn't work" or "Brakes make noise" would be more useful. In your post, include information like make, model, year and mileage of the car. Describe the problem, how it arose and what you have tried to solve it. Leave out irrelevant things like "I'm a single mom and I really need my car!" Nobody here can help you with your marital status and we all need our cars.

Welcome to the forum and we look forward to hearing from you.

 

thank-you, I got it now.
