Power brakes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck is a 1970 with 4-wheel drum brakes, non power. What is needed to convert to power? Booster, rod, brackets, MC. What else? Do I need to swap prop valves? Pedal? Is a drum booster different than a disc booster? And what do I need to look for to get the smaller diameter booster I've seen on some pickups?

I also found a 89 chevy van. Can anything be used from this to convert to disc?

I bought a booster for a 73 chevy truck. $85.00 Then bought the bracket from
http://www.****************.com/
$150.00 Used the same proportion valve and worked great. Now I'm converting to disks mainly for the look and will be changing the master and proportioning valve.
Night and day from manual to power even if you keep the drums all the way around

no change in splitter block needed unless you go to disc brakes in front then you would need a proportioning valve

ah maybe because he is a competitor with an advertiser or something. his name won't even show up . Weird!

It will stay drum for now. Disc would be nice in the future though.

Wasn't there a thread somewhere on this board about someone using a 73+ brake booster on their 67-72 truck to get power brakes?

Here is one, I don't know if it's the one but it may be. If you click on the search button on the top of the page your post is on and type in a keyword or words like "power brakes" it should take you to some threads. V. V.

thanks Ivscott-----sdkid, here is another pic. Remember if using stock pedal arm hole. from firewall mount to center of the booster rod hole is 8.5" Rod will allow for lengthening using split washers if needed. Hole may need enlarged on rod.
