What are the pros/cons of slotted and drilled Brake rotors for a car? How much life is reduced by these rotors
144199
get rottores with both...yes there out there...they stay cooler...reduce brake fade..and help the gases produced from the pads excape..wich can keep the pads from making full contact if at all...yes that last part is true....they last just as long if not longer because the chances of warpage is reduced......\n\nas for cons...cost

kakani P wrote an excellent explanation but I wanted to add an example to help you furhter understand a practical application.\n\nThe tooth on the front of a backhoe bucket is a great piece to be carburized.  It could be made totally of high carbon throughout but that would make it brittle and subject to break since it experiences many impacts and shock loads as it encounters rocks (or old concrete from foundations being demolished) and other debris in the soil.  We still would like to have the surface hardened to reduce wearing but we still want the core to be ductile to prevent premature failure.  Carburizing allows us to "have our cake and eat it too".  We can make the surface wear resistent and hard but leave the core ductile and able to withstand large shock loads through the process of carburizing.

only one single pad pushes against the rotor and the rotor gets pushed on to the pad behind it. the fluid will get contaminated by water and dirt over time and if u leave ur bike outside in the winter the lines might crack and the fluid will leak other risks are that depends on wat gets on to the rotor the breaks won't work as well as they are new after a while so tune up the breaks every few months and every new seasion. i had a problem with my frond disc due to the weather(the pads became too close to the rotor so they are rubbing against the rotor evey time i ride.)\n\nand how cold in celcius is 20?

With a big enough disk you can explode it due to centrifugal force. The resulting destruction can be severe. This has happened with race cars. (See ref.) That is why flywheel housings ("bell housings")are beefed up in racing.

Magnetic brakes are made up of two rows of very strong Neodymium magnets. When a metal fin (usually made of aluminum) passes between the rows of magnets, eddy currents are generated in the fin, which creates a magnetic field opposing the fin's motion. The resultant braking force is directly proportional to the speed at which the fin is moving through the brake element. \n\nSo the faster the roller coaster is moving, the more braking action occurs.  \n\nFor an automobile, purely magnetic braking probably wouldn't be a good idea, because you wouldn't be able to stop fast when moving slowly.  However magnetic braking is already in use for cars, in hybrid cars, when one puts on the brakes, the wheels turn a generator.  A generator works by moving wires through a magnetic field.  Moving the wires through a magnetic field generates electricity, the electricity generates an opposing magnetic field, which slows down the wheels while putting electricity back into the battery of the car.

Just a Pro. You have the slightest lag if you shift it without speed shifting. Also you could load up the engine with to much fuel by several on off throttle manuvers. But most of all you are controling your engine braking when shifting as well. You might want that torque range you get in a lower gear but you don't want it to engage at a low Rpm. Could put you into a slide or spinout.

I tend to have the same problem. I've reduced it to some extent by shifting the levers very slightly forward and down so now I rest more of my palm on the top of the levers rather than the crook of thumb and forefinger. The disadvantage with this is that the brakes are less well positioned for my fingers, but its marginal.\n\nTry too, changing the inward angle of the brakes to match the natural angle of your hands at the bars. Mine are toed in about 5 degrees.\n\nI also invested in better gloves with gel padding right where it gets sore - these work brilliantly - I know this for sure because just yesterday I forgot them, did 50 miles anyway, and I have a blister to show for it at the base of my thumb!

kyosho made a few back in the day ut you can still find them they are electric but if you want the bad boys take a look at this link i currently have ther grandnational and it kicks @SS the sprint is to be way faster\n www.wcm-corp.com\na good way to spend some money and have the best and fastest rc in your neighborhood

Take a motor mechanic with you, if you know one. If not ask around until you find one. I would avoid the imported ones as they tend to have higher prices on spare parts. \n\nAlso, shop around as there plenty of second hand vehicles to choose from and dont be backwards about bartering for a cheaper price with the sales people.

wow man that sounds a little crazy, like rocket science. i have standard 6in rotors and they rock and have never even in extreme conditions given out on me or had brake loss due to heat. i know your setup, id consider just doing one rear hyd. brake for weight/racing purposes, maybe even not use front brakes at all or just use v brakes for front.

Hehe ya i think a mechanic is a good idea cause i screwed mine up. I now have disc brakes which work a lot better and last longer but cost a lot.

DON'T!!!\n\nDisc brakes are very troublesome unless they're expensive multi-pot models (and even then they can be a pain). Not only that, you absolutely do not need them unless you're mud-plugging or doing serious downhill all the time. The only advantage they offer is that they're further away from the rim and therefore less exposed to the sh1t. Unless you're clever technically you can't service them reliably, so you'll have big service bills. The parts are expensive and wear out more quickly than rim brake equivalents.\n\nBuy better rim brakes if your present brakes are no good. Cheaper, lighter, no maintenance of any consequence, good braking in all conditions and fit and forget. Personally I like top of the range Avids - cheap, good looking and very effective.

That bike is not bad, and it is good that you are deciding against disc brakes...\n\nAnyway, I prefer Specialized.

Heat\nOver current due to a winding failure. \nContamination of the rotating components causing friction.\nHigh freqency components producing harmonics.\nMetal fatigue, from mfg flaws.\nOver loading the turning shaft.\nStarting and stopping.\nAll the above will generate heat which will destroy a motor.\n\nActually, motors will run longer when they are always rotating at a constant speed and constant load within the design criteria.\n\nMaintain clean environment around it will be the easiest assurance for longevity.

I think less than 100 in the world. What cool about them is they are completely carbon fiber and can top over 240. And if you get your hands on one, even second hand, the company will refurbish any parts on them for the rest of the life of the car.

The critical features of brake pads are heat transfer, toughness, rigidity, and durability.\n\nCompressed manure ain't worth shit in my experience.
