Bought an echo brake not that impresed really, because every time i ride the tpa comes loose, and on the outerside where the tpa is, there has been metal is sheering off by the ribbed rod that pushes the piston in on the lever, I dont know what to do. Also it leeks ever so slightly, I think it was a waste of money, but the engineering that has gone into the brake is very impressive cylinders are nicely made and you get more clearance for your cranks, and looks very nice, but for me it hasnt functioned properly. Here is a picture where you can see it wearing away the metal. You can kind of see that where the little ribbed thing has twisted so it slowly wears away the metal of the lever. Has anybody else had this problem and is there a way to fix it, also does QUACKERS have a reciept for this wherever he bought it, I would like to do something about this stupid brake.
