Single to dual reservoir conversion

[Tad]

Finally getting to installing my brake conversion to a dual master cylinder. I figured out the distribution block passages. Can someone tell me which of these two ports goes to the front and which to the back? 1 and 2.

Would probably be a lot easier to tell if the lid wasn't on.

#2 goes to the front

jazak5 is correct, the rear goes to the front brakes, the front goes to the rear .

If you are doing a disc brake swap, that is the wrong master cylinder. Not enough volume. 1973 disc brake master cylinder with 15/16 bore will work.

Still drum all around!

Number one is for the rear.

Not all master cylinders are set up that way.

And that would have been useful information. When you say you did a brake conversion, it’s normally a safe assumption that you installed disks. In which case the larger reservoir goes to the front brakes regardless.

Thank you. I changed the title.

The flare nut is usually a different size.

The front reservoir has a larger diameter flare nut than the reservoir closest to the firewall.
