In the summer of 2001 I changed the front brake pads (Bendix) and replaced the original rotors with new ones purchased at NAPA instead of having the old ones resurfaced (on my '92 SE). Had a set of these exact rotors put on my sisters '96 Buick Park Ave in 1999 with no problem at all...Just changed her brakes yesterday and her rotors are still in fine shape with normal wear.

Last week, while rotating my tires, I noticed that the front passenger side rotor had formed a lot of ridges and one larger groove in it - just not smooth evn after normal use. I took the brake pads off and noticed they'd soon be needing replacement, although way sooner than I had hoped for when I put them on in July 2001 - this time Raybestos PG Plus are going on. There was nothing on inner or outer pad that indicated why these grooves and ridges should have been formed on the rotor to begin with. Looks like there were a few small rocks caught between pad and rotor and they just etched into the face of the rotor.

The lug nuts were always rightened to specs to avoid wared rotors; the calibers were checked; overall both brakes are working properly; and the drivers side rotor was still quite smooth and was in no need of any resurfacing and looked to have normal use after 2 years. Still I can't figure out why this other rotor is in such bad shape now. Either way I think I'm going out and getting a new set of Raybestos PG Plus rotors when putting the new brakes on just to feel safer - I'll be driving with a small baby a lot this summer. Or should I have both rotors simply resurfaced to save money on something I might not need?

Go get slotted rotors at www.domesticperformance.com!!!! They run a little more then the Napa ones i bet, but they run a lot cooler. I just had mine resurfaced, and one is on it'* last surfacing so if they go bad, i'm getting the slotted ones.
