65 nova Master Cylinder

[pro68/540]

Hello everyone. I have a 1965 nova wagon drag car with a single m/c i want to go to a dual m/c w/o a booter does anyone know the correct m/c to get. Like one off a 67 nova or camaro ect. thanks everyone.

Need to know what brakes you are running F & R as this will have a big effect on what the "right" M/C is. If you're running F & R drums, I'd look for a M/C for a 67-69 Camaro with manual drum brakes (1" bore and "should" have residual press valves in it for the drums). If running Disc/Disc, you can use a M/C for a 68-76 vette with manual disc brakes (also 1" bore, but no residual press valves). This will also work for Disc/Drum, but you "should" add a 10 lb residual pressure valve to the rear brake lines.

In any case, you'll want to make sure you get a M/C with a "deep" pushrod hole to retain the manual brake pushrod. Newer M/C's (like the ones used in 70+ camaro) use a shallow pushrod hole. REALLY newer M/C's (80+?) use a 3-piston M/C with a shallow hole.

Forgot to add, another possibility is a '77 Malibu M/C for manual brakes. It's a 15/16" bore and (I think) is set up for Disc/Drum, but has the opposite plumbing as my Camaro, so I forgot about it. Depending on what front calipers you use, this might be marginal for fluid volume though (may not move enough fluid for big piston calipers)

I am making the assumption that with a single pot mc you have drum/drum brakes. You can just order a master cylinder for a 67 Nova with drum brakes. 67 is when they switched to the dual mc on Novas.
