[oletrucks] brake booster

["luke zsiga" <50chevy@gmail.com>]

I added power brakes to my 50 chevy and just connected the vacum line to the
booster, and when i start the engine it sucks my brake pedal to the floor.

Do i need to add a spring to my pedal to hold it in the up position?
or do i have too much vacumm? and need to add a valve to reduce the vacumm
going to the booster?

thanks again,

luke
