Where did you hear this? How do slots generate more friction if there is less contact area with the pad? Why does this cause quicker wear?The slots also generate more friction. Which is what you want for brakes.
It does reduce the life of the pads, but if you are concerned about stopping fast and are buying upgraded rotors and pads to do so, the lifespan of the pad isn't your first priority.
Sorry to get away from your question!I'm getting new brake pads but not sure if I should go with EBC greenstuff or Hawk HPS. I'm also getting power slot rotors. Has anyone tested this combination before? And what pads should I get?
Don't forget that holes help you save weight [idea] Hehe, at least in autox when in a light underpowered cars where braking is not too critical. All depends on the application. Hawk HPS and centric blanks are what a lot of us recommend as a top performing street setup. I run HP+ with centric blanks on the autox car, and I would say they are too noisy and dusty for me to recommend as a daily driver setup. They stop great though, and it is more than enough brake to look up sticky Hankook RS-3's. I don't have experience with the EBC, I'm sure there is an equivalent option to Hawks HPS though.Actually there are two reasons for slots or holes in a rotor.
1. It gives water a place to go when driving in the wet. You can make one complete revolution of the tire before the brakes sweep off the water in a non slotted rotor.
2. Pads as they get hot out gas and prevent the pads from contacting the rotor.
Both of these situations are more important in a competition situation where a few feet of in effective brakes can cost a race.
If the brakes are bedded in properly and not grossly overheated they will not glaze over. If you do glaze them over the slots certainly won't get rid of it.
Who had the best prices on the Hawk HPS pads? Looking to put a set on the front of my SVT. Had the Hawk ceramic pads and they were fine, but I just installed Centric rotors and thought that maybe I should put new pads in. The ceramic pads have plenty of life left, but I don't want to ruin the rotors with old pads. Thoughts and opinions?
