Re: Question about 98 Crown Vic brakes
On my Malibu I used Duralast Premium Ceramics (or whatever they call them) from Autozone with standard Duralast rotors, in the 15,000mi until I sold the car they hadn't warped the rotors, unlike the semi-metalics they replaced (which only lasted ~8,000mi), and still had plenty of pad life left. But the 97-03 Malibus were known to warp rotors if they were driven aggressively.
In short, If I were to do the breaks on my Mercury today, I would use the Duralast ceramics again.
1996 Mercury Grand Marquis GS ~89,000mi, Willow Green inside and out. It's very green.
1998 Chevrolet Malibu Base V6 187,000mi (sold)
