Slotted rotors, do you really brake better?

Slotted rotors, do you really brake better?

Ok, i was searching ebay. I see they have brembo slotted rotors on there. I can get them installed in 15minutes cheap by my dads friend. I just had brakes and rotors changed few months ago. I got the "better" rotors at autozone. They had like 15 dollars a piece or 25 dollars piece ones. I of course got the 25. I saw a set of the brembo on ebay for 80 or 90 dollars. Would i noticed a good braking difference? My brakes are the lifetime brakes.

um... not really... it just cleans the brakes and stuff... and help move the hot gas... other then that... not much... for ur size rotors... try to keep as much material as possible.

the less material u have on a rotor... then more likely hood it will warp... warpin is caused by the rotor not able to hold ne more heat then its capable of holdin...

u can just get brembo blanks... slotted or drilled will cause more noise... unless ur gonna get big brakes... then u should just stick with reg rotors with better pads...

THERE IS A DIFFERENCE-not necessarily BRAKING power BUT overall reliability and that they arent gonna warp on you over the next few months-thats the difference...also-w/ cheap rotors-you'll have to get them "cut" or "resurfaced" quite often b/c of the low quality level-i was thinking of getting cheapos from autozone, but i decided to go w/ drilled and slotted rotors from brembo on ebay.. http://cgi.ebay.com/ebaymotors/ws/e...2481497112&rd=1 a very good ebayer-i just got mine-took about 8 days to get them-they are awesome!

will cause more noise? are you serious? how much more noise are we talking about?

um... i dont know how to explain the sound that it makes... i sat in a few cars that have aftermarket brake pads and rotors... and make this "decelerating whirling" noise... i think it sounds pretty cool though...

it kinda lets me know that im slowin down from warp speed...

the drilled part was to reduce material... thus the weight savings...

the slotted part... was made to move brake dust/extra material out of the way... and to also help "cool" the rotor/pads.

AWESOME! im gonna be comin out of warp speed! "scotty, give me that power! Have you fixed the hyper drive?"

for the size and weight of most corollas, its good to go with just a bigger rotor, flat surfaces with biger calipers. With slotted or drilled, they do stop a bit better, but they also warp quicker. Especially if you have wheels where if it rains the get alot of water. I i think that u cant resurface any of those that are slotted or drilled.

i'm getting alot of that now, but it's just that my current brake pads are ready for a change.

sound kinda nasty sometimes... but it does sound like yer warping outta warp speed...

Crossdrilling was originally done to allow the outgassing of the asbestos pads to have someplace to go. Pads haven't outgassed since at least the early '60s, if not earlier.

This was always my understanding. Cross drilling was to get rid of trash. Grooves were meant to creat a vortex to cool the rotor, once the brake pads were released from the rotor. Think, when the pads are applied to the rotor, you have a large amount of metal to dissapate the heat created from the applied pads to the rotor( caliper, housing, frame and so on). Once the pads are released the heat is still with the rotor, no way to cool itself any longer,,, no place to go. Which is why the grooves were designed. Make any sense to anyone. This is not a fact, it was just what I was taught.

lol dave thats funny...

got my brake pads changed yesterday... damn had to get my disks rectified or something like that... got them looking spankin new for about $20 bucks in my local mecanic. (brake pads were almost completly used-up)

good news is no more warping sound nor sqeeking...

slotting is actually useful. Drilling is not......decreases surface area thus any gains from more airflow are negated by loss of surface area.

not to mention the drilling weakens the rotor so its more prone to break or warp.

ive heard of rotors having to be turned... but being rectified, thats a new one to me. i kinda enjoy it.

i dun actually know exactly what he did... i didnt ask any questions though it was fairly cheap and has given great results till now, my disks were yellow-y and had some small scratches... he took them away for a about 20minutes then brought them back looking as they came outta the box. I think he sanded them down a bit and dunno what else. He told me its maintenance for yer rotors.

you enjoy the starwars warp on yer brakeS?

The Brembo's are supposed to be pretty good because they are forged with the holes in them instead of drilling the rotors after making them. Cross-drilled rotors will stay cool, but you have a smaller surface and they can crack. Slotted rotors vent hot gas toward the center of the rotor to keep the brakes warm, which is needed in racing, but they will warp quicker because of the heat. It's up to you what to go with but DO NOT buy cheap rotors because they won't last.

not unless u have larger rotors...

well now, heres my theory on it. your brakes are working fine if you can lock up your wheels. all the bigger brake kits are gunna do is gunna be able to lock up ur wheels faster....

someone correct me if im wrong.

I'm really confused... So should I or shouldn't I get cross drilled slotted brembos. or should i get regular smooth brembos or something else?

this thread reminds me of monkeys throwing shit and pissing on eachother..... blah blah blah..... everyone is an expert, but like 2 people had any info worth mentioning

You should get regular smooth brembo's, also, do me a favor and contact Brembo directly and ask them if they actually make rotors that are both drilled and slotted for OEM applications (like some people on ebay *claim* to be selling), I think you'll be pleasantly surprised.

so wat ur saying is heat causes brakes to warp? but in another post u said slotted rotors help move hot gases? so wouldn't slotted rotors be beneficial?

if you dont plan to track your car, drilled and slotted rotors are overkill for the street. slotted rotors are better sutied for agressive driving like autox. If you plan to keep it on the street, better pads and brake lines are prolly all you need.

Yeah I agree,
I was in the twisties last week and drilled and slotted rotors help but as that fluid gets hot and starts to expand the hose....here comes fade again.

All a bigger brake rotor will do is resist fade better, because there is more material for the heat to go into, so the rotor can take more heat before it gets to the point where the rotor is too hot for the friction of the brake pad to be as effective, on a regular street corolla just get brembo blanks in your stock size, performance brake pads and stainless steel brake lines, that should be all you need

Yep, thats why you should also get stainless steeel lines, they wont expand like the regular rubber brake lines will...

lol... guys... if u guys never tried a set of big brake kit on ur car... then u wouldnt know wuts up....

like 90 percent of the vvti members told me its a waste of money.... and our brakes is good enough...

but they are all wrong... big brakes does make a huge difference... totally worth my 1400 bucks.

much better brake feel... firmer... stops faster... looks better... less fade... etc... go try it out and ull know wut im talkin bout...

and like i said before... those of u who have stock rotors and stuff... go with blank rotors... u dont want to remove any more material off the rotors... or else it will warp or crack easier....

and yes... all slotted and drilled are done in-house.... they buy blanks and drill em them selves...
