Frustrated with my brakes

it's not a check valve, it's a residual pressure valve.
And as long as the master is above the calipers you shouldn't need one.
Exception would be drum brakes. The residual pressure is needed to keep the shoe return springs from compressing the wheel cylinders piston back into it's bore.

I also have a A&C kit. I tried the manual master for the vette, way to big of a bore. I stood on the pedal and barely got it stopped. Switched to the power setup that A&C suggested in the manual and love it. One toe on the pedal will stop my car on a dime at moderate speed. Never tried high speed braking. But I feel it would do fine. I didn't check pedal ratio or any of that, just went with Joe's instructions.

Man I hope convincor is joking.

Saltshaker,

To clarify,By reducing the bore diameter of the M/C you will incease the line pressure at any given pedal pressure, however it will take more pedal stroke to achieve that pressure. This is benificial to a point, as it improves you ability to modulate the brake force, provided you have enough stroke length.

It sounds like you’re on the right track as far as the parts and pedal ratio go.
Do you have braided lines?
Are the F&R pads the same compound?
Bleeding can be a huge pain in the arse.
Did you bench bleed the M/C?
I pressure bleed from the wheels back towards the M/C to get all the major air out. Then finish with a few "pump the pedal" cycles for good measure.
I use a big syringe and clear vinyl tubing, just make sure to watch the fluid level in the reservoir.

Great questions: the front and rear pads are different,the master has now been bench bleed and the brakes seem to be working much better
