power or manual brakes

i am trying to clean up the engine compartment in my 85 c-10. i wanted to remove the brake booster and go to manual brakes. is this a bad idea? this truck is strictly a hot rod, nothing but a motor and seats. thanks

Poor idea - unless you want to consider changing over to a very HD 4 wheel disc brake setup such as SSBC, Wilwoods or Baers - then, even probably not really a good idea - I have power 4 wheel discs on my current Model A roadster project, just for peace of mind.

Power Brakes were standard equipment on these things starting in about '78.
Not any fun trying to stop one without PB either.
I had a 76 w/six w/o power brakes---only used it for runs to the dump.
These trucks are heavier than they appear--My 79 tips the scales at 4400.
454--4spd--saddletanks
Not sure that yours is much lighter. If you have a SB/AT, single tank, Short bed
maybe--400 lighter--That is considering the lighter frames of the 81 & newer.

I've got both manual drum brakes and manual steering. The one thing I would choose to have power would be brakes. I dont think you will like it going from power brakes to manual...For one thing it requires alot more pressure from your foot, then when the brakes "warmup" you gotta use even more foot force. I havent had a problem yet that I couldnt stop for, but for peace of mind and ease of use I'd stick with power brakes dude...

I've got a '78 gmc with no power brakes and let me tell ya, when it comes time to redo the brake system on the old truck its getting upgraded, years back I had a friend who had a mid 70's chevy halfton with a pretty potent 350 and no power brakes and you pretty much had to stand on the pedal to get slowed down, I found that it just ruined the fun of driving the truck knowing how hard it was to get it stopped.

Just my $.02,

Chris

It is a common misconception that power brakes increase your braking power, they do not. In the mid to late sixties 427 435hp Corvettes were available with 4 wheel manual disc brakes. Power brakes decrease the pedal pressure and will not increase your braking ability.

This I believe to be true---however, the disc brakes do require more pressure to get stopped.

The 85 came with power discs standard.
Having driven an older chev w/o power brakes but with discs

My 66 Elky w/ drum all around--------is much easier to stop.
And the power brakes will make it more pleasureable to drive.

I should have clarified my position more, I completely agree that your braking power is not increased with power brakes, but the effort to apply that braking is greatly reduced with power brakes which in my opinion makes for a more enjoyable ride.

I like manual brakes, I find it easier to modulate them
than power brakes. I've bought cars that had PB and
have removed the boosters, installed the appropriate
master cylinder and driven them into the ground...

if the size of the booster is the eyesore you might be interested to know that there is a double 7in booster out here that would get ride of the frying pan look FYI. I would keep the pw brakes easier and more effective in case you would have to pump them for a high speed stop, not that anyone would drive their hot rod fast. That might be unsafe

Depending upon your manifold vacuum readings (vacuum has to be at least 16" to operate properly), the question is mute. Proper brake operation can be realized with the proper M/C/caliper/wheel cyl piston size without assist. Of course, the foundation brakes have to be in good repair and no discount house parts used.

In the late fifties/early sixties, the use of a remote vacuum cannister was popular (not referring to accessory reservoir) and the actual booster hardly showed. Seem like someone in the speed industry would offer something similiar for a show car.

I had no idea what power assist was until 1973.
