Could anyone tell me what the fitting sizes are for both lines so that I can make a set of lines to bench bleed this damn thing.

Keep in mind that they aren't the same.


This is a manual brake master cylinder on a 68 if it makes a difference.

Thanks guys,:thumbsup:

you need adapters, I am pretty sure the threads in the MC are...9/16x18 and 1/2x20

What adapters do I need? I have the pastic adapters and rubber hoses but the adapters seem to be sucking air.

I was thinking about using cooper lines and I guess it would be brass fittings to fab a couple of lines from the ports back into the M/C.

You can buy the necessary fittings/lines in steel at an autoparts store.

I have the sizes and part numbers, but not in front of me.

:WTF Was I thinking.
Seriously, thanks for telling me something I should have been able to come up with on my own. Sometimes I just go blank.:cheers:

They are metric. Go to NAPA and get the transition lines they sell, about 10" long with the correct flare and nut. That is what I use to bench bleed. I have used those "help" plastic kits, syringe type, and vacuum but the best are the steel lines bent up and over the M/C.

Pretty sure Red's correct, dont have an MC in front of me but those two adapters appear to be the most used in my kit :) Thexton(and others I am sure) make a nice kit with all the adapters P/N 803

Metric , eh?? That'd be neat. :D

The ones on my 72 & 75 were metric. I had to bring the M/C in to NAPA before I would believe it myself.

Here they are.

I actually picked a couple up this morning, now I just need to bend them up and get to work.

Thanks for the help guys.:thumbsup:
