power brakes or non power??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am slowly putting my 70' chevy shortbed back together, I am converting it over to front disc, but right now I am unsure if I should use a power brake booster or not.

when I had the drum brakes on, I had no power brakes, but only 3 drums were working, so I didn't get a feel for the non power set up.

I really don't care that much for the way the factory boster and rod looks, but I guess that it would be eiaser to apply pressure to the master cylinder with power brakes.

the non power set-up looks cleaner, but I am not sure of how much pedal pressure would be necessary.

any one have any comments or suggestions on the subject??

personally, i'm going with non-power and 11" rotors, disc all around.

cleaner and saves some weight too.

good luck!

I've got a non-power setup on mine and I really like it. My truck has front disks/rear drums. The master cylinder is off a '85 Chevy 1/2 ton truck (with power brakes) and the proportioning valve is off an '85 S-10 blazer (but I'm pretty sure it's the same one used on the 1/2 ton trucks). I smoothed my firewall, so I wanted a cleaner look. Plus the master cylinder body is aluminum and the reservoir is plastic, so no more rusty master cylinder! It bolted right up to the firewall and the lines hooked up without any adapter fittings. The only thing I had to do was slightly enlarge the hole where the master cylinder passes through the firewall. I just used a die grinder with a grinding stone. Didn' take much to make it fit.

Don't know if this is true or not. But if you go with dot 5 silicone brake fluid you get a firmer pedal too. Iam going with the same setup as custom chevy and am using dot 5 silicone fluid. Its a little more costly but won't break down in moisture ie. water and if spilled it won't screw up your paint job. I got mine from JC whitney. I bought a gallon for 69.00. I thought I'd use alot of it but did my whole system with a little over a quart. Good luck with your decision.
