1st test drive - didn't make it home!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Finally got the whole truck in primer, worked out all the leaks in the bags, and for the first trip on the road in 18 months, I was heading to the local custom muffler shop to get an exhaust system.

Never made it!

On the 55mph highway for 3 miles, truck started slowing, and slowing..... then saw smoke. Pulled into a gas station with all 4 brakes locked, zero pedal travel.

I did a search on "locked brakes" and most of the suggestions point to the prop valve as the most likely source of the problem.

BTW; Brake system is original rear drums, with all new parts, hoses and lines. Front discs are from a '77 C-10(with power brakes). I DO NOT have the power brakes (the booster was missing from the junker, and I don't really like power, anyhow.)

Questions:
Is the prop from a power system the same as for a non-power system?
Do I just need to 'reset' it by holding the pin/button in while I press the pedal?

On a brighter note: the rear fuel tank and fender filler neck mod can take fuel as fast as they can pump it......

Thanks,
