4 Wheel disc, soft pedal

-
I am leaning towards master cylinder being too small also. I believe the front calipers are 2.5" and if the rears are also, there's no bias between front and rear.

I have 73+ front disc with Ford Cobra rear discs. The caliper bores are significantly smaller. And I use a 15/16 master.

These are the later 2.75" front calipers, but the rest of your point stands.

Thanks everyone for your help. Going to order a larger MC today. I'll post back with results.

Oh gotcha. Yes, let us know the results. Are you getting the new one from Dr. Diff?

Yes, most likely. I bought all my other brake parts besides the rears from Cass, and only those because I didn't want parking brake provisions. My mistake. I'd do it differently if I could.
 
What are you working on? You can try tapping on the calipers while bleeding. I'm not impressed with rightstuff, and wished I bought something else. If this was a manual brake car, the pedal may need to have the pedal re-drilled due to the ratio wrong. This is typical of too small of MC. my 2 cents

Yes, kit uses the GM front calipers as rears.

Car is on the floor currently so I'll need to verify later today, but I looked up the kit I bought, got the caliper p/n and did some digging. 2.5" is the bore size according to the almighty Google.

That's a pretty large piston for the rears, what are You using for proportioning?
