Master cylinder question

What works for me footbraking is the largest bore rear wheel cyls and secondary shoes in both positions for more friction surface area.

Not looking to use the proportion valve. My first Duster had the stock Kelsey disc up front with a drum brake master (like the one I measured) and that car was the best stopping bar none. Hope to get the same feel again. Of course I was 29 then, might not have the leg now lol.

I just bought a new strange MC. Their recommendation is with 4 wheel disks, use a 1.125 bore and with 2 wheel disk, 2 wheel drum to use a 1.032 bore. I can say, without even bleeding the lines the pedal feels good, better than the mopar aluminum one I had on

Dont forget to look at break pedal ratio when changing from power to manual.

What differences are there between the Strange MC and the Mopar aluminum one? Isn't the Strange basically an aluminum Mopar MC?

Thanks Brian, the one I have is a Strange. The 1.03 one, was in a k-frame kit for a 63 b-body (wasn't used) witch is ok since I'm using a 64 pedal. How is your car coming along? Who is gonna be out first, LOL?

Not sure what the differences are. the mopar one might have had an issue, Although one thing I did different going from one to the other is that I now have the rear brakes plumbed to the rear port on the MC. I read that the rear port provides more fluid flow, and I'm trying to make sure I have good holding power on the rear when staging. we'll see.

Hey Mike, pretty much done here. Front alignment next week. engine has been on the dyno and I've driven it around the neighborhood, which I very much enjoyed, not sure about my neighbors !

Unless it's a stepped bore MC, 2 different size bores in one, the only difference in ports is the capacity of the reservoir. Disc brakes are self adjusting by allowing fluid to take up the space as the pad wears so the reservoir is larger.

If you want more holding power in the rear increase the size of the wheel cyls or calipers.

I've got strange discs in front and back with their recommended MC. I'll wait and see how that works.

Oh, you are my envy. I can't even push mine around the shop yet.
