Can I use a 1/2 ton brake booster on a 1 ton?

[pat565]

I have the original booster and m/c assembly from my half ton project, and would like to know if I can use it on my 67 1 ton that I am swapping the rear diff and front suspension from a 87 1 ton.
Or should I just use the hydroboost assembly?

Thanks for any input

They used vacuum assisted brakes on the big trucks before changing to hydaboost. The big difference in vacuum boosters are the over-all diameter & diaphragm quantity.

So, the 1/2 ton booster/mc assembly will increase the pedal pressure vs non-power brakes but it won't be comparable to a HB set-up. Whether that's good or bad is dependant on several factors (presonal preference being a main one).

If anything, the mc needs to be sized based on the caliper & drum piston volume so it needs to be for a HD 3/4 ton Burb/truck.

Thanks for the input.

I think I might just go and salvage the parts for the hydroboost off the wreck in the backyard. It's good that I haven't hauled it away yet.

I will say that I hate the way they (GM) mounted the front brake calipers on the 87 donor truck. They won't fall off, but what a pain to blow apart!
