southern california
so i added ssbc front disc brakes and a ssbc manual master cylinder,but brakes dont have much stopping pawer,i hve the correct pedal,but i am wondering should i remove the factory junction block and add a proportioning valve to the rear brakes and run no junction block to the front brakes?
the car was originally factory manual drum brakes all around.is the junction block restricting brake pressure to the front disc?

It's worse than that
The stock master cylinder would be set up for 4 wheel drum brakes with the same size ports and valves (roughly)
Just get a master cylinder for a Mach or Boss that has disc brakes (it will have a bigger reservoir for the front)
Then play with proportioning valves
Put a booster behind it while you're at it
Good luck

Not sure what you mean SSBC
As long as it has a bigger fluid portion for the front disc brakes it should work

Sounds nice, post a picture of master cylinder
Your rotors and caliper hat bolted up to the oem spindle okay?
I'd like to see a pic of that too
