I have a customer with a Yale, propane sitdown truck. Model LC52LT2524P with serial # AH-102882. I know that it is an oldie and most times we wouldn't mess with it. Are brake parts like the master cylinder still available? Can anyone bring me close as to the year of this truck? It is used once a week at a hardware store to unload sand, blocks, ferilizer etc. A stacker truck would do them well but they just want this to go. No brakes and no fluid coming out of the mastercylinder. Thanks.
