Allison Posted June 22, 2009 Share Posted June 22, 2009 My 1957 B model has a vacuum line and an atmospheric line running to the trailer. The trailer has a vacuum booster which operates the master cycliner. My vacuum booster has a bad diaphram and i am having one heck of a time finding another. Any ideas... also if i can not find a diaphram could i replace the booster with a newer version??? Please helpAllison Quote Link to comment https://www.bigmacktrucks.com/topic/9816-vacuum-booster/ Share on other sites More sharing options...
Speed Posted June 22, 2009 Share Posted June 22, 2009 If I was doing it,I'd probably take it off and ship it to Reno Brake,in Reno Nv. and have it rebuilt. There's likely a place near you that does that work;I believe those have a huge,stiff spring in 'em that could cause a lot of damage to your hide if you took one apart,so better to play it safe and let the pro's do it. Worst case scenario,they'll probably have the parts you need if you can engineer a safe way to get it apart and back together. OR,maybe you can convert a more common booster to work in its place.

Speed Thanks for the help speed. I have the booster apart and your right there is a large spring. Im would think updating the booster would probably be smarter.. they probably work better??Allison Quote Link to comment https://www.bigmacktrucks.com/topic/9816-vacuum-booster/#findComment-37071 Share on other sites More sharing options...
