What is the name of your state (only U.S. law)? For this question RI, but I am looking for a more general law answer.
Say you have a person come in and wants brake pads on their car and you measure the rotors and they are at the discard thickness as set by the vehicle manufacturer. You inform the customer of this and they say they just want new brake pads slapped in. So you document this and have them sign that they declined new rotors and leave. The rotors fail at some point by cracking, is the shop liable or protected because they made the recommendation and documented it and documented the customer was advised and declined.
