Proportionate valve or distribution valve

[Stocker]

Not a stupid question at all. That's a distribution block for drums/drums. When you convert to front discs, you'll want to change it out to a proportioning valve. I believe you should also change the MC but let's see what others have to say. MC for front discs uses a larger reservoir for the discs and a smaller reservoir for the rear drums.

If you want to get picky, the front discs, which operate at higher line pressure (the reason for the prop. valve) use 3/16" lines, and the rear drums retain 1/4" lines.

What about in '71? Just rebuilt my MC a few months ago, both front and rear reservoirs are the same size. I supposed an accurate question would be: "Did this change occur the same time they went to discs?"

Just going off my memory of working on my '72..... apologies if it's not quite accurate, but that's how I recalled it.

I finally got an email from Cpp, after 2 weeks, and that guy said that I had to change the master cylinder out as well. This is different than what the other guy told me over the phone. I checked the master cylinder that I have, and it does have a larger front cavity than the rear. I got in my proportion valve the other day. Should the master cylinder I have work?
