Brake master cylinder

You're absolutely right - the engineers at Toyota certainly knew what they were doing back when the car was designed so there's no real need to use a larger master cylinder if there isn't a need to displace more fluid. If the stock brake system gives a bad pedal feel, it's most likely that it's just that the fluid has absorbed too much moisture and needs to be replaced.

Oh, and I'm using the 90-91 SW20 master cylinder which is the same size as the AE86 one. I just had one laying around and since it was in a lot better shape than the original one, I cheapskated my way from buying a MC rebuild kit.
