Brake Question...

[hedtrpr]

Hi Ya'll!

Next (maybe) dumb question is:

I put a new brake system in my '38 Ford rodded pickup including a under floor mounted pedal and master cyl. So, when the engine is off the brake pedal is all the way up but when the engine is running, the pedal is sucked about a third down to the floor and stays there. I know this is becuase of the vac. system but I don't know where to adjust the pedal to: it's running or non-running position?? Also, should I have a spring pulling the pedal back up each time after being depressed?

Big Gobs Of Thanks,

adjust with the engine off.. but with your description, I see no need to make an adjustment

The pedal should go down 1/3 if you start the engine tho, that's with a properly working booster

If you have your foot on the pedal, and you start the engine, and the pedal falls, check the rear brake shoe adjustment.

Not so - in a properly functioning power brake system, the pedal should go down when you start the engine.
