The truck is a 60 C10 and has a brake booster that a PO put on,I don't think the truck came with one. I was wondering if the boosters bad or maybe the master cylinder. Any thoughts are appreciated.I was going to drive it tomorrow to a truck show about 50 miles away but I'm not sure if I should now because of the brakes.

I appreciate your reply,I'll check it out. It looks fairly new but who knows. At least I know it's safe to drive that way hopefully.

Then apply pressure to the pedal & start the engine. The pedal should drop a little. If not you don,t have vacuum to it or the booster is defective. Sometimes a system has some air in it from previous service & works its way out. You suddenly get a better pedal. It,s possible an emergency brake cable is sticking & not letting the rear brake shoes return.

I looked at the vacuum hose going to the booster and the PO had the pcv valve and the booster connected to the same hose,using a plastic T fitting.I ran the booster vacuum line separtely and it seems like the brakes are much better unless it's my imagination. I don't think the booster was getting enough vacuum before.

I was at a car/truck show yesterday and noticed that on some trucks I saw. I'll have to locate a fitting for it like that. I was going to connect the pcv valve to the back of the carburetor,but I like your suggestion better.
