I installed Brembo rotors and Hawk pads this week, installation went easily. The Brembo rotors were Made in Mexico and don't appear to be quite as heavy as the Napa rotors they replaced. Weight of the Brembo rotors is about 16 pounds each. Broke in the pads according to Hawk'* directions Stopping is smooth but I won't be pushing them for the first 100 miles or so. Hopefully they are gentle on rotors as advertised.
On the old rotors the discs were a discolored blue over most of the braking surface (except at edges). On our Porsche 968 with Zimmerman rotors the braking surface is universally bright, no blueing). As you can see in the photos, three of the four surfaces had the blue discoloration, while one looked normal. Is this due to dragging pads, or is it nothing to worry about? The old pads were barely worn. I wonder if they contributed to the warping of the rotors.
The rotors were barely worn as well, should they be turned or discarded? Must be the frugal side of the family that hates throwing away anything that looks almost new.
What would cause the Blueing of the rotors? Comments?
