[Diy_efi] OT: ABS retrofit into older car...

[Amenson Scott (AC/ESC4)]

Perry,
Almost all vehicles have proportioning valves.  They are essentially the
same devices that we put on our race/modified cars except for that the
spring tension (rear pressure response curves) are not externally
adjustable.

I wonder if he's referring to those delay valves used to delay the onset of
rear brakes.  The stated purpose is to prevent rear brake lockup by
preventing
the high pressure surge when someone stomps the pedal in an emergency.

Those devices are not neccessary if you have properly biased your brakes.
That is the whole purpose of a bias valve, it limits pressure to the rear
brakes so that the front brakes lockup first.
