I have a question regarding vaccuum brakes. My El Camino currently has vaccuum brakes and was curious what all I need so they will work? All I have come up with is a TTA Vaccuum Block that has a port for the brakes.
If you mean switching the GN brakes to vacuum, you've got almost everything you need. The only other thing would be a break pedal assembly from a vacuum brake g-body. Or you can drill a hole in your current pedal for the rod form the brake booster. The hole you have now will be too hight. Do a search, I think somebody had posted a link to a page that showed you where you would have to drill the new hole to make your old pedal work. I switched my brakes to vacuum a few months ago, got everything I needed form my local pull-a-part for $30. The only thing I don't like about the conversion is that I can't do big smokey burnouts any more. When my car starts to build boost, it starts to creep forward and doesn’t break the tires loose until I start to roll. With the powermaster, I could hold the car in one spot all day if I wanted. -Gabe
camino70 alot of guys run a vacuum line from the vacuum block directly to your vacuum assist with no problems . I part out alot of GN's and find alot of cars with vacuum set ups installed. Shouldnt be any problems.
