**rogertheracer** · 08-14-2010, 02:26 PM

i have a heidts front clip with 11" rotors/ 78-88 metric gm calipers and 9" ford rear drums.
which bore m/c do i need 1" or 1 1/8"? these are manual brakes.
its a 64 nova pro street with 31-18.5 x 15" rear tires.

thanks, roger

Sounds like a nice setup! The manual brake applications like yours will use part # CP31500-C (1" bore) Whenever you use a large power booster (typically 8" dual or larger) then the 1 1/8" would be used.

thanks aaron, is that a direct bolt on(no mods.) to my 64 nova (standard brakes) ?

Yes, this will bolt directly to the 2 studs coming out of the firewall.

The MCPV-1 is our All in one master... This master will allow you to adjust the proportional valve to fine tune the rear brakes.

Aaron, I just received my MCPV1-C ( WOW IT IS NICE)
Question, I'm reading how to do the bleeding withe the syringe.(master in car)
Is this proceedure done with the brake line connected to the M/C and
with the bleeders closed ?
Please expain in more detail.

Thanks, Roger
