Anybody know where I can find a Brake booster for my 73 RX2? Mine is leaking.

Thanx

Exactly what is it leaking?

The brake booster is only full of vacuum, and when it is leaking it will whistle.

If you see brake fluid, then it would be a bad master cylinder.

Mann,
Several years ago I had the same problem and was not able to find a brake booster. I picked up an Rx7 booser and clamped it in a vise and split it (the top and bottom are threaded together). I did this by making a tool that bolted to the top piece and unscrewing it. This also allowed me to used the larger mater cyclinder.

Just a thought...
Good luck!

So over all your car braked a lot better with this swap?

Actaully,
the car braked about the same but the pedal feel was a whole lot better. I felt like I could take to the edge without locking it up.

I don't understand what you mean when you say you split the booster. Can you explain a little more? Did you continue to use the rx2 master cylinder or did you use the rx7 master cylinder and change the lines? The rx7 booster's diameter is a lot more than the rx2's. When I first got my rx2 I tried to change to the rx7 master/booster assembly and found out that it didn't fit! It interfered with the clutch master and the holes would need to be re-drilled. How,excactly did you make it work? Thanx

FYI the 1979 Rx-7 booster is the smallest of all years of Rx-7 if that helps any.

Hey Mann,
I have been out for a couple days, so I have not replied. I will write something up and post it soon.
