brake leak help

[gallo]

i got a leak between my brake mc and booster the booster looks corroded just a bit but idk if its from the fluid. the pedal started feeling really soft a while ago and today i had to stop and the pedal went almost all the way to the floor in order to stop long story short no fluid and i found the leak between the too . . would it be the MC or the booster also i was searching before i posted this and found that the abs auto s13 MC is bigger would this help stop better if i am running stock brakes all around or what do you guys recommend. . and is the boosters job only to assist in softer pedal?
thanks in advance

Sounds to be most likely an old BMC.. you can get a reman. one at any local auto parts store.

Brake booster assist with power braking so you don't have to put as much force down with your foot to slow your car down.

I would just buy another 15/16

I run stock bmc with my 26mm z32 front brakes (with stainless lines) with no problems has plenty firm pedal feel.
