I am looking at a 1964 chevrolet c-30 cab and chassis. its a big window, with factory chrome package ( chrome grille, bumper, etc.) its a very clean truck. It had a flat bed on it , and was used in a construction co. At some time it was put on a 1985 1 ton frame. problem is when the brakes are applied, it jerks left or right. The owner said he replaced everything in the frontend, except the ball joints, and steering box itself. he installed new calipers, and pads. I don't want to buy this thing if its gonna need a new frontend under it. but if he replaced all he said, ( it looks all to be just put in within the last month or so.) what could it be, I'm out of ideas. Any help?
so, problem at all speeds? any shaking/wobble when just doing regular driving with no stopping? did he replace the front rotors?
