Way to be descriptive there, ace. :bandito:

 

I think NPautoparts is not really doing much and needs to be talked to about advertizing on HAN, thats all I have seen in his posts, were brands of brakes he uses, and says are better than OEM Honda..

 

this isnt a sales ploy. I am a mechanical engineer, that appreciates the science and engineering that is put into the design of automotive parts. And i happen to own a auto parts company that sales Brembo brakes as well I am just trying to give my opinion and straighten out some facts. Ive done extensive experimentation and testing in labs on the behavior of different types of metals when under shear and normal stress. There are 2 stresses that are applied on the rotor, normal and shear. And there are 3 factors, the modulus of rigidity "under shear stress" or modulus of elasticity "under normal stress or compression", then the force and surface area where the force is being applied, which is the surface area of the disc where the pad touches. Whether the disc was cross drilled during casting or after, doesnt make a difference in its ability to withstand the normal and shear stress applied by the pad. However there will be a slight difference in the way the disc transfers the heat that is created. But not enough to put a hudge emphasis on, and the modulus of rigidity and elsticiy depend on the material used, so what truly determines the strength and integrity of the rotor is the material used. not how the shape was created.

feel free to bash me even more
i like it.

Ok, I wasnt bashing you, if you would have posted that earlyer then everyone would have understood why you were here.... From reading all of your posts you sound like you are trying to tell us we were wrong with what we buy and then you throw the names that you happen to sell at us, that you think work better...

Do you cary Raybestos? Also have you done any reasearch on them? Or how about what type of brake pads are beter?

What would you say is beter? Kevlar or Ceramic?

 

neither was I, just stating what Ive learned from my materials engineer classes. if you've done experiments and those somehow state what ive been taught to be proven to be wrong. then so be it.

 

I hope this is a little more direct.

Bendix (Jurid) makes certain OEM brake pads (BMW), so not sure how they are 'better' than OEM pads.

As far as Bendix, I've seen countless posts about how Bendix Ultimates are poor. Under track conditions, the pad itself CHIPS off into chunks OR they catch fire. They also wear the rotors down pretty hard. However, Bendix does offer a variety of pads, so I'll give it that.

Aftermarket pads SHOULD be bigger than OEM pads, therefore they SHOULD have better stopping power.

ANY brake rotor will crack if not broken in properly. But I've seen more FAILED drilled-rotors that were not drilled from Brembo than were.

I'm still wondering about your motives.

 

Rotors: Brembo blanks
Pads: Hawk HPS or Hawk HP+ pads
why: cause the rotors are cheap and I can get quick. The pads are a quick to heat up and high friction coefficient great for autocrossing and track days.

 

I dont carry Raybestos, i carry BENDIX and ABSCO which are the direct competitor of Raybestos for certain lines.
I havent compared the 3 directly in lab conditions, i plan on doing that sometime next spring, i have however done road test with many pads and i feel that BENDIX and ABSCO have performed better, I have convinced many of my clients to Switch over to BENDIX or ABSCO. And they have all been extremly satisified. The last person i converted to ABSCO is an owner of a MAZDASPEED, and he keeps on telling me how impressed he is with those pads especially since they cost literally 50% cheaper then the OEM pads from MAZDA. anyway.

Between kevlar and ceramic?? well kevlar is an incredible polymer, it is extremly strong and light and maintains its strong mechanical properties even at extremly high temperatures. The only problem, its looses its strength upon compression. they also function great in cold condiitions, and have a high coefficient of friction, they will stop you real fast

Ceramic, there are many different ceramics that can be used, so the results can vary. But there is hudge potential for ceramics, i have taken courses where we discussed the implementation of ceramics in jet engines and internal combustion engines, great potential, also for braking application. Now since ceramics are insulators, it takes time for them to heat up and to function properly, but they can operate at extremely high temperatures. And there is very low coefficient of friction. As far as a friction material, i would only recommend for heavy duty applications where high temperatures are attained and maintained. Ive had several cars with ceramic pads and i dont like the fact that in cold weather they fucntion poorly. But when they heat up, they keep on stopping great and the last long. and very quiet.

so it really depends on what you expect from your brakes. I dont think one is better then the other, they each have their own advantages. What i think, if you want great stopping power, kevlar, if you want something that will keep up with you demanding driving and keep on performing at 100% over and over for a long period of time, ceramic

Hope this answers your question

I have Brembo Blanks and Axxis Ultimate Pads. They were recommended by many people here on the board, and the setup cost less than the stock parts on GBC. I can't quote numbers, but I would say I am happy with my setup overall. Next time around I think I will look for different pads because the Ultimates are quite dark and I have to clean my wheels more often of the brake dust buildup.

 

maxboost, does everyone who posts here have to have motives?? honestly i was just suprised at the number of people who have brembo's. I didnt think they were that popular. I am not trying to make enemies i was just giving my opinion, and what i feel is a better alternative to brembo's. There is no advantage to me stating that their are better rotors then brembo's since i sell brembo's, and many other rotors. I thought i was helping you guys out by giving you my input on the product. not that you need my help. Just though some people would appreciate it.
anyway, good night
