After many returned rear master cylinder kits to ebay, mikes XS and a host of other companys i have found a kit that you can use for only 19.99. You will only be able to use the 2 rubber caps, the piston seal and the return cup. The spring in the kit will be to long and the piston shaft too short. But all and all it works great. here is the link.

"Ruben" hasn't signed-on for a while, but only the 1978 and 1979 had rear disc brakes; so I think it's safe to assume that it applies to the rear master cylinders for them. But it's not my $ on the line, so….! ;)

Finally got my rear master cylinder rebuild kit that Ruben has posted here. I have swapped the rubber part and it seems to fit just fine. Hope this works. I'm just not sure about the new spring. It is much longer than the original and wondering if I could just it down or should I look for new spring at a hardware store or something?

Is there something wrong with the old spring; can't you clean that up and use it?

Duke, Thanks for asking: if you look close at the pic with old spring in it, you'll see it is kinked near the top. Somehow the metal got eaten/corroded away and was hanging on by a thread. I was able to cut the new spring, included in the kit, down to the right size and flatten the bottom out so it sits flat. Also swapped the small black metal top to the spring. Put it all together and It works great. No leaks. A big thanks to Ruben for posting the link to this rebuild kit

I appreciate the update.

However, if we can try not to take this Link thread and turn it into a Tech thread, it would be appreciated.

Maybe start a new thread in Brakes if there needs to be any more discussion on it.
