Default Rock hard pedal and locked brakes

Hey guys,
My 97 impreza l (auto) no abs is swapped with a 99 sti type r and 5*114 hubs and brembos, i swapped brake booster and mc along with the proportioning valve from my type r front clip (no abs) and now my brakes are locked up just in front i beleive and my pedal is rock hard....
totally unsure if i should source a 4 port non abs master from a svx, and instal it on my type r booster (i also have a 04 sti booster and mc) or is it my prop valva that is defective.....

or should i swap it all to the 2 port mc and booster and prop i have lying around...

Thanks alot

With the front wheels off the ground, can you turn them?
Can you compress the caliper pistons?
Are the pads a little loose or tight in the calipers?
Are the brakes "locked" engine on, off or both?
The hose between the booster and intake, is it the original one or the "new" one?

I'm thinking your parts are correct (non ABS to non ABS) except for the booster hose. The rest could be assembly error.

Answer questions so we can go the next step.

Check the booster hose......the one on there is from a turbo car, correct? But you have it on a NA, correct?
