So when you increase the disc diameter and keep the hole density (holes per unit surface area) the same, you will increase the surface area. Frost |

Terror of da Nitez Group: Advanced Members Posts: 1,294 Member No.: 383 Joined: Apr 26th 2003 Location: san francisco | you want more good braking power? replace your old jankyass master cylinder, and brake booster, then get yourself some nice new blank rotors, sport/ street pads (if it is still a street driven vehicle), ss brake lines, good brake fluid, bleed the shit out of the system. that way you will have refresh most of the components on your braking system, not only will you have better brakes, but safer ones too...what good is 3000$ big brake kits...when your master cylinder is leaking like a lil bit**? |

I agree that good pads and fluid make a much bigger difference than drilled rotors. |

We're the People's Front of Judea! Group: Advanced Members Posts: 13,123 Member No.: 1,355 Joined: Feb 28th 2004 Location: Las Vegas, Nevada | Xd'ed rotors also have less surface area in contact with the pad |

t3h_n00berer Group: Advanced Members Posts: 2,471 Member No.: 3,280 Joined: Sep 22nd 2004 Location: Brampton, Ontario, Canada | So I imagien then, because according to physcis.., having cross drilled and slotted rotors just adds the effects? Sounds like amazing braking but maximum pad wear.. Not exactly what we all need... |

Changed your title, Biatch! Group: Members Posts: 431 Member No.: 24,823 Joined: Jun 13th 2007 Location: Puerto Rico | Okay, got sleepy half way through. Kudos to Nick for posting all that info (first time in my life I have seen that much info about brakes in one place, and I have seen a lot of info). I'm sure everyone already understands the purpose of drilling brakes. Unsprung weight, but they crack, yadda yadda. EOS. Now, slotted rotors. I don't know if someone mentioned this after I stopped reading, but here is a little factoid. The little slots act like a very fine knife cutting away the pads bit by bit. You can barely notice it, but it's true. As for the brake fluid. ALWAYS study up on the fluid you want to use and NEVER mix it with old fluid. They all have different operating temps and quite a few of them get easily contaminated with humidity. Yes. Everytime you open up the cap, even if just to have a look, a little bit of humidity mixes with the fluid and it ruins it. As easy as it sounds, as easy as it gets ruined. Some are very well made and don't get spoiled that easily, but it still happens. Companies should have charts of how their products stand up to these conditions. Give them a call. And if the bastards won't say, Google is your friend. As for pads glazing, it's generally due to their materials. Other times, the pads and discs themselves aren't up to the work of constant hard braking and glaze, and may even catch on fire (seen it in person, what a riot). This is why super cars usually opt for ceramics, and why F1 cars use carbon fiber. Someone said that using smaller discs meant using smaller pads...... not completely true. You do need to use a pad that won't actually overshadow the disc, but doesn't always have to be the case. Some people get slightly larger discs while still using the stock caliper/pad. It really depends. TRD-hachi-roku: Replace the brake booster? Do you know how much those cost? It is generally rare for one to actually break. Replacing parts that are still functioning properly is just throwing money into the garbage due to lack the ability to inspect things properly. No offense. Also, you forgot to mention obtaining brake calipers with more clamping force. Better pads and better/new discs help, but they won't work as well as some people would like to believe without opting for a stronger caliper Only problem.... buying aftermarket calipers is one, f**king expensive ordeal..... so, people wanting to get stronger calipers, just use Google and try to see what better calipers from other cars can mount up to your current one with some mild mods |

Rather than think about slotted vs. drilled, think about this: 1) Brake fluid is the most important part of a braking system. Change it and upgrade it, and make sure you bleed it properly, hammer it, and check it again. 2) A good tool is available from your local Radio Shack. It's an infrared thermometer. Point it at your left brake and right brake after a session of hard driving and the temps should be the same. 3) Your rim choice affects your brakes more than your rotor choice. 4) Both slotted and drilled rotors use more pads that a fat woman during her period. 5) For most reasonable (even race) circumstances of the time, smooth rotors only lose on a cold, wet, rainy course to the other two. 6) Proper brake bias is more important than slotted vs. drilled. 7) I know a fanboy who can prove w/a lot of finite element analysis that slotted+drilled is the "ultimate." |

IDW Member Group: Members Posts: 18 Member No.: 24,953 Joined: Jun 22nd 2007 Location: Honolulu | I'll ask my bike mechanic about the wave thing. It looks like it's good for show, or maybe on bikes, but my eyeballs scream that there's not enough material there to do the job. Bike rotors get a lot more air than car rotors, so the wave thing might work on bikes. I'd be surprised if they ever show up on cars because of warpage and durability issues. |
