Do you mean replacing the cylinder and rotor with the later larger-sized version, or do you mean heavier weight rotors? I've read the post regarding replacing the smaller brake parts with the larger brake parts--including going to 17-inch wheels. Whew, even though I've swapped a good number of rotors and calipers in my younger days.No, save your money and upgrade to HD brakes.
Well, my mechanic replaced them free of charge, so maybe he was mistaken, but he wasn't lying.Rotors don't warp! Your mechanic lied to you.
Does the fact that they also grind very loudly and dust very heavily (in addition to pulsating) lead to a specific problem?
