Upgraded 4 pot sluggish brake pedal
Hey guys I just recently upgraded my brakes.
I had the single piston brakes on my 91 n/a.
Is there anything I could do to get the same pedal feel I had before the upgrade.
I also realized that I replaced the booster, maybe I accidentally changed the pedal height,
could adjusting the pedal height help as well

My original booster was leaking air and all i did was replace it with the same type.
I never removed the original MC. I removed the 4 pot brakes from my vert 1990 shell, but i never removed the MC from the Vert. Is the MC from the vert the same size as the 91 n/a?
or is it bigger?

to OP, try having brakes power bled at a shop. You also said your booster was leaking, you may have gotten used to less assist so now that you have a good booster it takes less effort. I have the 4 pots from factory but replaced both calipers for remans, bled, pedal still tight. actually better then my impreza ever was and my 2.5rs is the 90's style MC and booster but 1" bore instead of 15/16. if u have abs you might need to cycle the pump too to bleed it.

You have my number so I'm not sure why you're asking this here...
I'd you're positive you're not losing brake fluid, it sounds like a bad master in your Subaru..
Power bleeding is not necessary on an FC. The most I've ever found you need to do is drive the car around a bit and then bleed all four corners again. A lot of people also don't seem to realize that you can actually damage your master cylinder when bleeding by allowing too much pedal travel.. Never let it hit the floor. Put a block of wood underneath the pedal or something.. You don't really want it traveling past the point it would when braking very hard.
