Ross, Thanks, snip It's been my experience that metallic pads really chew up rotors that don't have a perfectly flat and true surface. Snip my practice is I don't routinely grind rotors or drums unless they are already warped, and once ground I have found that they warp sooner. I have had front pads go as little as 25,000 miles before they are dead to as much as 90,000 miles depending on the car and whether it has much compression braking characteristics or not, such as late freewheeling type front drive automatics used by GM. My olds ate brakes up. Most cars that I have owned I have driven through their life with out having to touch the drums or rotors. Although my Mitsubishi had a rotor ground due to warping 180,000 miles. I bought the car new. I have used nothing but semi-metallic replacement shoes or pads for about 50 years now and prefer their stopping power and longer life. Sure would like to find out what ceramics characteristics are though! John -------------- next part -------------- An HTML attachment was scrubbed...
