Surprise, surprise at around 40k my wife’s ’19 Ascent has a nasty pulsation and her pads where worn down to about 3mm. Yes I could have had Subaru turn the rotors and ”lubricate” the pads correctly. But I expected better quality from OEM parts and I doubt they’d warranty worn pads. I ordered the R1 concept Carbon Geomat and Optimum OE pads from them. We burnished them in and went through a heat cycle. They stop significantly better than OEM brakes when the vehicle was new, they almost stop too good and they took some getting used to because they where so damn touchy, now and the vehicle one dives. I figured it’s just new brakes and they’ll go back to stopping like it did before but they only improved after 2k miles. The old brakes stopped just fine but the R1 concepts just stop that much better. I pulled the fronts and measured the pads after 2k and they haven’t even lost .001. Rotors look good with no grooves or discoloring.
