Hopefully they are gentle on rotors as advertised.
On the old rotors (after about a year on the 95 SE) 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.
While the old Napa rotors that warped were definitely beefier than the Chinese cheapies, they also failed fast, less than 12 months and only about 8, ooo miles. The blue discoloration indicates overheating was the contibuting factor in the rotors warping.
I found the invoice for the brake pads, " Raybestos Quiet Stop". I'm thinking that the problems Andrew and I had were due to the brake pads, not the rotors. Hopefully the newly installed Hawk HPS pads will be gentle on the rotors as advertised. Until I found the invoice, I didn't remember how much I spent on the Quiet Stop pads, they were close to $70, about what I paid for the Hawk pads.
