'64 Disc/Drum Master Cylinder Question

I had a '66 a few years ago with a stock non-power single circuit master cylinder, stock rear drums, and CPP's drop spindle/disc brake kit up front. The brake pedal effort and feel was really good and the front brakes locked up before the rear like they should so no proportioning valve was needed.

I'd like to replicate that pedal effort/feel when I redo the brakes on my '64 C10 but with a dual circuit master cylinder instead. From what I've looked up, a '66 MC is 1" bore; is there a dual circuit MC with a 1" bore on both circuits so I wouldn't have to use a proportioning valve? I'd like to stick with manual brakes, I don't like the pedal feel of power brakes.

Re: '64 Disc/Drum Master Cylinder Question

Thanks for the suggestions!

I've always either just gone back 100% stock on brakes with our restorations, or on the Chevelle we built we used a CPP kit that came with everything. The '66 had all stock brakes until I swapped to front discs and it ended up working well with the stock master cylinder so I didn't look further into other options.

Next question- Should I use a metering valve and proportioning valve? I did some googling and found this... I can see where an adjustable proportioning valve could be a plus on the rear of a truck to keep the rear from locking up, and being able to adjust for different tire and brake shoe/pad compounds would be nice. I don't really understand the need for a metering valve though, the '66 didn't "nose dive" without one.

Re: '64 Disc/Drum Master Cylinder Question

Sounds like the metering valve would be best used with the adj rear prop valve....or just use a proportional valve....I mean combination valve.....
Good video btw...
