I have been having a very annoying problem for quite some time: my brakes squeaky like an old freight train as soon as they get warm. Piston New brake calipers completely overhauled front and rear, absolutely light and resistance-free running, sliding bolts new. Everything greased with suitable means. Flooring Textar, discs Textar each new (previously ATE, has squealed the same) sliding surfaces and co ATE antiquietch paste (no difference to ceramic paste or copper paste) I am somehow at the end with my Latin. PS: brake values absolutely at new car level, no delay, absolutely uniform, no matter which brake. Brake fluid also new, system completely rinsed and ventilated.
