I recently purchased a used truck from the owner of a repair shop. I was informed at the time of purchase that he had just had the transmission replaced and also the brake calipers. My son who is taking auto repair in high school noticed that the brake shoes were worn more than he was comfortable with and replaced them. Upon backing out of our steep driveway he lost all use of brakes. (hydraulic line not tampered with by my son was improperly attached to the new calipers-certified affidavit by A.S.E. acquired) this resulted in a near fatal accident when the truck couldn't be stopped before rolling into traffic and my son was T-boned in the drivers door totaling the truck less than 2 weeks after getting it. Is there any recourse toward the seller on faulty work can we get our money back?
