what kind of brake pads do you use???

[Pedal]

i said it was the HP+ and the rotors really have nothing to do with the cracks i am talking about

this is a quote straight off hawks webpage

Use of these or any high-coefficient/high temperature pads will, over a period of use, create -heat checks- or small cracks in the rotor surface. These generally will occur only on the front rotors. These cracks should be monitored on a regular basis as they will eventually widen and/or extend toward the rotors outer edge. Cars without brake ducting (i.e., showroom stock) may see this process occur even faster. With continued use, heat checked rotors could shatter. Heat checked rotors should be replaced before cracks reach approximately 1-inch from rotor edge (or if cracks grow excessively).



i have done research and the sloted and crossdrilled rotters. the comment about rotors was just an FYI as to why i was looking at getting pads

[yudalicious]

of course, using any sort of brake pad "weakens" the rotor (no matter what brand, compound), hence the rotor is more prone to cracking. Using more aggressive pads speeds up this process. The use of brake pads do not directly CAUSE the rotors to crack, but eats away the rotors (and take into account high heat and firction) which weakens the rotors (and that is why I said in my last post how aggressive pads are). I should have clarified what I said in the above post when I said pads don't exactly "cause" rotors to crack.

Which is why it is very important to buy rotors that are not ALREADY weakened by drilling/slotting. Of course, if you're using street pads then I think they will be ok, but if you want to use more aggressive compounds and want to track your car, then I would venture to say those rotors will crack pretty fast.

there are 2 different trains of thought on the whole thing,

1)Use more aggressive brake pads and QUALITY oem style (solid) rotors. effectively increasing the drag co effiecent or...

2)Use more aggressive rotors and QUALITY pads, again.. effectively increasing the drag co effiecent

both options have pros and cons.

since in today's world pads do not outgas anymore, the only real function drilled holes serve is to reduce unsprung weight... the slots effectively "shaves" a layer of pad material off, keeping the pad fresh, perhaps that's what you meant by increasing drag coefficient (or rather, friction).
for 2) i would like to add that people who are using this "train of thought" are probably using bigger brakes and the longer lever arm by the bigger calipers farther away from the center of the rotor to generate more brake torque (which is what stops the car) to compensate for the comparatively less aggressive (lower friction force) brake pads. Again it is important to use quality rotors.

edit: i am using hawk HPS (hardly an aggressive compound) and brembo blanks, and they have served me well for a street car, dusts quite a bit though, tht's my biggest complain with them. I am going to run hP+ next time.

explaining it in person and explaining it in text is sometimes difficult, you got what i meant
