I have found that stock roadster brakes, properly set up and adjusted, work=
just fine in non-racing applications. =C2=A0I have both early (1966) and l=
ater (1967-1/2) cars. =C2=A0I have had the '66 1600 with a U20 motor in it =
for over 40 years.

I tried to send this, but from the wrong email.....so I think it got cut.
It's very difficult to guess on the braking response of a wheel cylinder si=
ze change on a disc / drum set-up.
The response / braking torque to pressure is Linear with disc brakes and sq=
uared or even cubed with drum brakes.=C2=A0 Best to use a proportioning val=
ve on the rear to limit braking torque.
A proportioning valve is miss named as it changes the pressure response to =
pedal travel - which flattens the torque response of the drum brake.
