My brakes are seeing their last days and I have some questions about rotors and pads.

1. Cross-drilled rotors wear the pads faster, correct?

2. What about slotted only rotors?

3. I'm not going for bigger rotors. Would Brembo OE replacement rotors show much of a difference? Or is it just brand name appeal?

4. I'm thinking of getting steel braided lines, do they show much difference?

5. I would like a pad with linear braking feel. Since I am not familiar with the companies that make pads, could you offer some suggestions?

Thanks a lot for your help.

This is from my remembering of the stuff I've read, so it may not be completely accurate, but I'm sure/hope they are.

1. Cross-drilled should wear out pads slower, it allows the heat to dissipate more quickly, thereby working the pad and rotor less.

2. Slotted is same idea, but less effective than cross-drilled. Main difference is that cross-drilled can get warped easier (drilling holes in anything will lower their structural integrity).

3. Sure Brembo costs more. They probably make very little difference; however, I don't want to go crashing down the side of a canyon because I wanted to save $100 on rotors. Don't skimp on important things . If anything, it's peace of mind.

4. Theoretically, steel braided lines help w/ better stopping power because of the slack created by rubber lines expanding from heat. If you are gonna get new rotors, why not lines? .

5. Just don't get metal pads, they squeak like mad. OEM is always at least decent, however, lately even they have been using lower quality material (just did my rear brakes a few months ago), and they tend to get squeaky also.

For more info, I believe there is a big brake kit/300zx brake kit on group buy on zilvia. The guy who runs it puts in a lot of info, similar to what I've said above but in much more detail. You can go there and read up on it for better details.

hope that helps

one thing if ur looking for a performance rotor oem size slotted are better than cross drilled slotted work better and the holes on cross drilled create stress points which leads to cracks quickly.

there is a lot of this info in the tires/wheels/brakes/suspension forum if u hav more questions

there are also people there that own shops that sell this kinda stuff that can really help, but look thru the forum first cuz u mite find out stuff u dont think of wen u r asking questions
