Brake Master cylinder rebuild kit
I am trying to locate someone who can sell me a brake master cylinder rebuild kit or a brake master cylinder for my 1981 Rx7 FB. I have found no-one in Spain. Can anyone help? The problem also is i have no way of recognizing what the part numbers are. It has two feeds from the side and one from underneath with no bleed nipple. Help please!!
I recently was looking for a master cylinder rebuild kit as well. What I found was that you can purchase a reman master cylinder for around $30 and the rebuild kits are hard to come by and are more expensive.
The drum brake master cylinders are around $75 reman and the rebuild kits are cheaper.
This is disk brake master cylinder:
This is drum brake:
You will notice they are very close to the same but the front line outlet has an extra hex shaped plug in the end.
If you need, I will be happy to purchase one and ship it to you.

That sounds great but from the pictures it looks like i am a hole short. I have three holes for the brake lines. 2 on the side and 1 underneath. And if you are sitting in the car the 2 are on the right of the master cylinder. If they have a a replacement for mine that would be great but i need the right one for this car. Or am i just looking at the pictures all wrong. Do you have an email address for them?

link to a thread of me fixing my leaking bmc with lots of pics https://www.rx7club.com/1st-generation-specific-1979-1985-18/disappearing-brakes-465602/page2/ (post 39)
here is a copy and paste of my post in another thread. part numbers so you can look it up at part stores maybe rockauto.com will ship to spain or mazdatrix or maybe even your local mazda dealer?
btw i heard that the hex nuts at the end just meant that the BMC was rebuilt already and tapped the old holes to bigger sized tapped holes for new threads

When I needed to replace my leaky BMC for my GSL 4-disc brake I had a hard time using online catalogs to find the right part I needed and even a wrong part was delivered to me. So I just decided to make a list of the part numbers people can directly search for so there is no confusion to getting the right or wrong part.

You are describing the normal ports on all the master cylinders. This one included.
Like I said, see if you can find one and if they will not ship to you let me know.
