Too late TPF you have already given information that can be used against you in a court of law, lol. Seriously though, if you read Rothwells thread, he removes the brake fluid cap, but doesnt tell you to put it back on, if you followed his instructions you would eventually lose your brake fluid and lose your brakes. Claims direct here we come!!! We live in a world where common sense is optional and where you have to think about the legal position before you give advice. The most common thoughts going through a DET's mind when being asked by a customer how to do something is "does this person know what he/she is doing?, Should he/she be attempting this?" Personally I wont give advice on brakes at all, if someone has to ask then they dont have any business repairing something that can kill themselves and others.
