I just bought it , looking at it now, installed the batteries and took it for a ride , the brakes seem to work but parking brake doesn't, seems there is sound coming from axle I believe it almost sounds like a tire rub, the sound isn't constant, the brake pedal (linkage) looks corroded. I'll need to look at some pics to see how it's supposed to look. I think the old owner may have messed it up worse trying to fix it. any help/advice appreciated.
