brakes on our trucks

[Killer Bee]

I can't answer your question but I'll offer this bit of advice.. don't drive a single reservoir brake system without a working manual emergency brake.. in my brief percentage of years driving single reservoir equipped trucks, I've needed the manual emergency brake three times.. most recently two weeks ago.. both trucks I've experienced total brake loss in were manual trans so pucker factor was minimal but both were also more controllable with manual emergency brakes..

I'll be looking forward to hearing the answers to your questions.. I'll be overhauling the brake system in my 65 C20 sooner than I thought and not decided to keep it original or upgrade to dual reservoir..

good luck and be safe!
