Despite what everyone else puts on the V, the original GM rotors and pads are perfect. Serious road racing, like glowing brakes, probably changes something. I have no clue how anyone can tell if the brake system on a V is better with the aftermarket stuff. Unless, of course, someone needs slots and holes for the looks. Absent serious road racing, I have no clue how someone thinks they are getting something better that is driveable on the street.
Pad break-in is critical. Read and follow directions. Make damn sure rotors are clean. I start with easy stops to warm up the rotor and pads. Then gradually brake harder and harder from 60 mph but nowhere near overheat them. Never activate anti-lock during break-in. I put 170,000 miles on my factory V1 set. I never had that particular car on a track however.
I finally gave up on all aftermarket crap.
l had a 90 SHO. I disintegrated the factory brakes. I upgraded to a later model factory brake system. I disintegrated them. I tried so called high performance pads. I disintegrated them. I finally found some pads that seemed to work well on the track when they got hot, but would not stop on the street. Of course then I started screwing up rotors. From my perspective it is hopeless.
I had the same problem with clutches on that car. Finally had a dual clutch custom made that worked, but it took four tries. Then I had to upgrade the slave cylinder. But at least the clutch worked on the track after that.
I will post aftermarket pads and rotors as a question. How does one figure that crap out on a V?. All hype, no facts from my perspective.
Man, this post wound me up this morning. I need to go clean out the latrine or something.
