Hello all. So after buying my 85 rx7 a few weekend ago, and noticing a weakness in the brake system, I have found that there is a leak in my brake system, right under where the master cylinder meets the booster. I looked up the brake system in the service manual online, and I'm hoping that it will be a simple fix, something like a broken o-ring that sits between the booster and MC, and not a major fix, like buying a new MC or even booster. Of course I'm new to all this, so I wonder what all of you think. Is it likely a broken MC? Will I need to simply replace an o-ring?
What is the rx7 public's diagnosis?

 

Buy a rebuilt master cylinder. Brakes are not something to cheap out on.

Do you mean specifically a rebuilt master cylinder, or would it be alright if I just bought a new one? (http://www.autopartswarehouse.com/se...ster+Cylinder))
Or even a repair kit? (http://www.autopartswarehouse.com/sk...n+%26+Steering)
Sorry I'm just curious about how to go about doing this.

 

Reman or new theres little difference except price. Get which ever
you are comfortable with. Note that if it has leaked long enough into
the booster it may be bad as well. You should check to make sure
its functioning correctly before putting the new MC on or you'll end
up doing it twice.

 

new is preferable over rebuilt, imo

 

Check with RockAuto.com, prices are almost always farrrrrrrr better than everywhere else.

 

Yeah thats where I got my booster from. Good prices and shipped fast.
