Upgrading my Master Cylinder & Prop Valve - Thoughts On This Combo?

MobileCustoms said

When I look up the master cylinders, it looks like the ones for the manual setups all have the larger bore and the ones for the power brakes have the smaller bores.
Do I want to use one designed for power brakes even though I am keeping it manual???

Thanks again

Many here use a 2-bolt MC for a 90's Dodge truck, on a 2-4 bolt adapter plate ($30 ebay).

The smaller bore will give an easier pedal, at the expense of slightly more travel. Many think the smaller bore in a "power MC" is backwards, but they aren't considering the lever ratio in the A-body stand-off brackets.

Another concern is that the manual brake rod has a rubber bushing on the end which locks it in the MC piston. The MC piston might have an internal groove to help, but should still lock fine in a "power MC". At least, I was test-fitting and couldn't remove the brake rod (64 Valiant) from the 99 Breeze "power MC" I used, and ended up ripping the rubber bushing in doing so. A manual MC also has a rubber dust bellows that bolts to the MC. On the power MC I used, I super-glued a bellows to the protrusion (post w/ photos).
