I'd always heard that the rear port on the MC was for the front brakes and vice
versa. But the front port is 3/4" and the rear port is 5/8". Does that matter?
The MC is part of a standard reman'd unit from AutoZone, so I don't really have
anyplace to call that I can actually trust.

Should I stick with rear port=front lines?

Not to confuse you, but I just replaced the wheel cylinders on my '66 today. It has an unidentified dual master cylinder and the front port goes to the front brakes. I too have heard that the front went to the rear and vice versa.

My point: it appears that it has been done both ways, depends on the setup.

I'm not an expert, but with a drum setup I would think it wouldn't matter, as long as both reservoirs were the same size and the plumbing worked out. PLEASE someone correct me if I'm wrong.

Also, I'm finally removing the master cylinder off of my '67 coupe for 66coupeNW tomorrow. I will check it closely and see how it is plumbed and let you know.

The way it is "Supposed" to be, is the rear bowl is for the front brakes. I think what some of you are seeing, is over the years where people have redone the brake lines, they hooked it up the way it made sense (ie front bowl, front brakes). On a 4-wheel drum setup, it is not really going to matter one way or another.

front port/back brakes..rear port/front brakes..the rear port is usually a bit larger and holds more juice

Teebone's right. The front brakes do most the work and usually have a bigger fluid section.
