[Roadsters] Brakes Phil Erickson

[Gary and Cindy Ault]

I have found that stock roadster brakes, properly set up and adjusted, work just fine in non-racing applications.  I have both early (1966) and later (1967-1/2) cars.  I 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 size change on a disc / drum set-up.
The response / braking torque to pressure is Linear with disc brakes and squared or even cubed with drum brakes.  Best to use a proportioning valve 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.
