Are My Brakes Gone For Shit?
My front brakes are making a horrible noise. It sounds like the brake fade indicator telling me to get new pads. I've been hard as hell on my brakes for the 21,000 KM my car has on it, but they couldn't be that worn already could they? :confused: The Mazda guy said that they are only under warantee for 20,000 Kms or 12 months. Both of which my car has passed by about a week or so. :(
If I need new pads, I'm thinking I'll just go for the whole slotted rotors setup while I'm at it. Has anyone got any thoughts on what I'm hearing? |
Ya, they screech like a power searchin' mofo... I just wanted the slotted / drilled rotors for auto-x and show. I've had my current discs so hot that they're warped now, so I figued that instead of having them resurfaced, I'll get complete new rotors that look and function better. The stopping power will be decreased, but the heat disipation will be alot better.

ookkk... where have you been for the past 2 weeks? did you *not* notice that big thread about brake rotors? for show, fine... but for autocross, they won't do SHIT Check out this thread: http://www.protegeclub.com/forum/sho...threadid=15997 |
Yeah that's the rotors alright. I burned mine out in 9000km. They were shit to begin with though. Partially auto x'ing, partially not. Brakes are your best friend. Just as important for autocross. You can go faster for longer peroids if you have less stopping distance and brake fade.
Mine got so bad I was having to use the e-brake to slow the car down at times. Stock rotors won't cut it hardcore :D :D |

Slotted/drilled rotors do help in braking...but only under extreme braking conditions. Under hard braking, like those experienced in real racing (Sebring, Road America, Road Atlanta, etc) when the vehicles are slowing from say 140+MPH, gasses are generated creating a very thin cushion between the rotor and pad. The term is out-gassing. The slots/drills aid in the relief of out-gassing. Cooling effects are negligable/nil since the the speed of the air going over a rotor's surface (especially those that are 'vented') is enough to efficiently dissipate heat.
Removal of brake dust is another factor of slotted/drilled rotors. Slotted rotors also aid keeping a somewhat "fresh" surface on the pads. (I.E. removing any glaze that my have developed) |
My car was totaled. No need to care about the brakes now. Check sig.

hello and welcome to 30 years ago Since it doesn't happen any more, explain to me why slotted rotors are still used on race cars such as those used in the LeMans series? |
lol.
You really are theMAN. ahahhhaha. J/k :D |
TheMAN, why are you always so damn angry. People do get tired of your constant belittlement. I have read the post that you have provided several times. Do you expect us to accept your statements as the words of the all wise? You have an uncanny knack for killing a thread by basically implying that someone is stupid and to "stfu". You started this argument.

lol. Well said, "thePR5OWNER" LD

There are a couple of real benefits of slotted or drilled rotors... (1) the scraping action of the holes/slots constantly exposes new pad material and keeps the pads from glazing, and (b) the holes/slots help water escape when you're racing in the rain. European teams often use slotted rotors for these reasons, which is why you see them at the American LeMans Series. However, American teams generally don't use slotted or drilled rotors because they say that the benefits are minimal and are outweighted by the drawbacks- increased pad and rotor wear. It's a matter of opinion. However, no *real* racing team in the world (Porsche and Viper Club lapping session yahoos are excluded) believes the commonly rehashed misconceptions about slotted/drilled rotors... that they decrease stopping distances, decrease fade, increase heat dissipation, or reduce rotor warpage. They do not do ANY of these things. On a street car, the ONLY things that holes or slots will do is look cool while they wear out your pads faster. :rolleyes: Please, oh please, help me spread the word so I don't have to rehash this again! :rant: To address the original topic, there IS a proven rotor upgrade that REALLY DOES decrease rotor wear... cryogenic freezing. This treatment hardens the rotors, decreasing wear and warpage. Check the following link: http://www.frozenrotors.com/ ;peace; |
