O.K. I know we have talked about this before but can I run a stock dual manual master cylinder without any proportional valve? Do I have to run one or should I just connect the front and rear lines? I'm running on sat so I need advice ASAP Thanks, Don

Don, With the stock master cylinder,You need to use a proportioning valve. An adjustable one would be nice but, if thats not an option, use the stock one.

Good Luck,

Hey, two of my friends at the same time. Snowman is right Don, about the best way to go. However, I have run with the front and rear lines connected so they have the same pressure. With drum rear and disk front this gives a proportion that works fairly well. It is not adjustable though. I have used it where the rules said no prop or other adjustments.

This setup works because drums need less pressure than disks. It ain't ideal but it ain't bad either. It is cheap. SLEEPY

I run a stock master cylinder with no proportioning valve with 4 wheel disc brakes and it works well.
