Can anyone give me the correct centric part number for the 79?
Rock auto and mazdatrix both sent me 130.45100, the tube threads are incorrect. The tubing threads easily into the old master, new ones stop after about 3/4 turn. I’m reluctant to force it, but is this the correct one?

looks like the right number, but maybe you got something in the wrong box?

 

Probably different thread pitch? I should have an adapter running around here somewhere from when I did my brakes.

 

The last time I got brake line parts from Rock Auto they sent me FB thread pitch parts, not SA like I needed. Maybe their catalog is confused? I find it hard to believe Mazdatrix would be off though.

SA thread is M10 x 1.25
FB is M10 x 1.0

 

@Benjamin4456 Thank you for the pitches.. I didn't have it handy and wanted to include it!

@mwpayne If the thread pitch is the FB pitch. What I did when I switched my SA brakes to later was redo the lines to match. Then when the calipers where delivered they included the adapters so I didn't need to change the lines. D'oh!
If that is the path that you are looking at I recommend the nickel copper lines since they are easy to bend..

 

Thanks all. I have 2 old correct masters so I’ll probably use one of those. I assume it’d be a good idea to rebuild it, something I’ve never done. Would the kits be the same as the FB?
Or is there somewhere to send to get them rebuilt?

 

Now there’s an idea.. adaptors. Any idea where I could get them?

 

It's probably going to be a job for ebay or a specialty store. I found a few opportunities on ebay. How many do you need? You might be able to find something local but in my experience it's not worth the hassle of visiting six different stores to end up going the online route. This may not be the case everywhere but we are in the same area so if you DO happen to find a local store I'd LOVE to know.

If you only need one adapter I should have you covered.

 

I’ll probably just rebuild the original or send it to be rebuilt.
I appreciate the help!

 

So decided to use the guts from the FB master into to body of the SA master.
I’m trying to remove the back section of the master, it plunges in and out, but can’t get it removed.
Any tips? Or would this even work?
Worst case, is there somewhere I can send it to be rebuilt?
