i have brembo cross drilled/sloted and i love them now i need to learn how to fade method them because they lock up on me when i brake too hard

 

That's a problem with your tires not providing enough grip. Just ease off the brakes untill you regain traction, then you can start to add a little pressure again. Rolling friction is higher than sliding, you brake in a longer distance with the tires locked, and it puts flat spots on them which is bad.

 

oh yeah i learned that the hard way couple months ago...damn i hate bald spots...i wont do that again

 

You guys are killing me. Everyone is an effing expert here. Yes, it's better, NO it is only for looks. Brake pads of 10 centuries ago are not as good as brake pads from last week. My Dell computer was obsolete the minute after I hit "confirm order". Truth is truth. Holes dissipate heat faster. Metal expands and contracts faster when it can transfer heat faster. Thus cross drilling can cause cracking UNLESS the holes are strategically placed in the rotor. Best bet is vented. Plain and simple. Solids glaze, and yes, "outgassing" still occurs. Venting allows the gasses to escape faster than a solid rotor, but not as fast as a cross drilled rotor. You do the math. And finally, YES I am an expert. But my 15 minutes of fame are now up.

 

with cars period its always give and take, not too much to purely add

 

SOoooooooioooooo

back to the purpose of this thread......has anyone had good (or bad) experience with these brakes???? The link to the brembo disks are interesting but im pretty sure he was interested in the three he linked to. The zinc coated ones are interesting, even if the disk rusts, the hub area should stay rust free.


F1 brakes are black because the are carbon fiber. They also use carbon fiber pads. They are not drilled/slotted. They last about 250 miles. Sometimes less


I was going to post a pic of an F1 setup but ******* F1 copyrights all the images. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$

 

so what.. if they post pics online, they are legal to repost elsewhere

 

we paid $251 shipped for slotted and drilled rotors in the front, brembo blanks in the rear and carbon/kevlar pads all around from NOPI.com................

 

I think it's pretty obvious that Drivarotor doesn't really know what he's talking about. He's confused about what vented and solid means. Solid rotors are ones where there is just one disc of metal that both pads clamp on to. Vented rotors have two discs of metal separated by vents internal to the rotor, they have solid faces though. Their purpose is to pump air in between the surfaces to improve cooling, and yes, they doo cool better than solid ones.

I beleive he was reffering to slotted rotors, which are ok, but I wouldn't waste my money on them, and they'll still be more likely to crack than a plain rotor. Holes are stress risers, no matter where they are, no matter how they got there (cast in or drilled), no matter if they're chamfered or not or whatever. Having these stress risers in the rotor will cause it to be more likely to crack. Period end of story.

I doubt that drilled rotors cool better, there's not going to be much airflow through the holes at all, as the air is moving perpendicularly to the holes and it won't want to turn the corner to go into the hole. For radiant heat loss, the holes just face themselves, so that's not very effective.

Plain rotors can be bought for less than $25 each, so that's under $100 for the whole car. Even if there is a slight performance advantage, it's definetely not worth the 3-4x price increase. If you want less fade, get better pads, better fluid, or run some better brake ducting.
