Info For Purchasing new Brakes

[FiReBReTHa]

Hey Guys just thought to share some info on them, im quoting from the GB Post i have going on.

Info
""The purpose of cross-drilled, slotted, or dimple rotors is to
dissipate heat
by degassing the hot gasses created under driving condition.

CNC machined for precision & balance
Military spec. Plating
Prevent premature warping
Prevent fade
Reduce operating temperature
Reduce stopping distance
Prolong the life of the pads and rotors

Cross-drilled: Holes are drilled through the rotor to dissipate heat. Cross drilling is very effective for heat dissipation. It will prolong the life to the pads, rotors and improve stopping power. It also shed off water under-wet driving condition.

Slotted: A line cut on the surface of the rotors to dissipate heat and increase bite. Slotted rotors will bring up the operation temperature of the braking components much faster over cross-drilled, yet it dissipates the heat at the same time. The added bite will reduce the stopping distance. Slotted rotor does not scarify the structural integrity of the rotor.

Dimple: In a way it is very much like slotted rotors with the
cross-drilled looks. Work the same way as slotted rotors, but looks exactly like cross-drilled and less pad wear. Dimple rotor does not scarify the structural integrity of the rotor.

The combination of cross-drilled and slotted or dimple and slotted will give you the best of both world. It will dissipate heat and increase bite for better stopping power.

The slot in our slotted rotors does not run over to the edge of the
rotor. Slotting the rotor over the edge will weaken the structural integrity of the rotor. As it will create weak point."

Stainless steel lines are to help with braking because under braking your rubber hoses that connect to the calipers expand under pressure whereas Steel will not and transfer that energy to the brakes rather than being lost in rubber exspansion."

Hope This post helps you guys out.
if you have any questions about brakes or the GB please post.

I'm still baffled why Brembo says to install the grooved rotors so that the grooves pull "in".

 

[Todd TCE]

I'm more puzzled why someone would make some of the claims listed there.....

You can buy those if you want to reek of poser.

Modern pads don't release gas, so anything other than a flat rotor is just less surface area for the pad to touch.

in reference to 'pulling' in air between the grooves and the pads perhaps? im not too sure i havent heard that so im not too sure right now.

This is a thread, please post! any info you contribute is good bro.

so your pretty much saying that these are worthless and arent worth the money? they perform better than stock..... and are near to the same price? explain your point because that just sounds like your sitting on your ass going. thats stupid. FMICs are stupid, AE equipments stupid, dont say something dumb like that before you know what your talking about.

And with that more friction therefore more heat is generated as well, and in some heavier use, then leads to warping. the slotting and cross drilled and in addition with the fact that the rotors are vented for better cooling and avoids brake fade.


Anyways, im not attacking i just would prefer more beneficial posts.

You are a poser if you think a car that drives on the street needs brakes that are cross drilled/slotted.

Modern pads have come a long way, and for what it's worth, they don't need that crap like slotting/crossdrilling/dimple drilling.

so your saying because i go AutoX im not allowed to drive my car on the street because im a poser??

yes, modern pads have come a long way. but they still have the issue of cost, and efficency, dependent on use. and still a pad is a pad that is used by pressured friction which causes heat, and eventual warpage. "That Crap" helps you save money by retaining your rotors longer and keeps them performing well. Even on the street.

POSERS are buying pieces of crap rotors who just randomly drill holes in the rotor because it looks cool. or going into pep boys and buying plastic disks that look like Xdrilled rotors to cover their drums.

Just because you car isn't fast enough to need them doesn't mean that other people who have fast cars are posers. Every car I have ever owned(z28, Trans am, stealth Twin turbo, eclipse, etc..) has experienced brake fade or "melting" at some time or another. Cross drilling and slotting the rotors greatly reduces the high amount of heat that is created when braking fast or braking often. Don't post your unexperienced opinion and unwanted insults until you get a clue of what you are talking about.

If you guys will quit arguing about other things for a while we can return to the question at hand....

I'll have to pretty much take the side of one person and agree that much of what is offered on todays "performance rotors" is pretty much less zing and more bling. Not that it's not valuable in the right application; looks.

There's little value to any sort of gas slotting, drilling, or whatever on modern day rotors IF a proper pad is selected to work with the rotor.

Most people can't even difine 'performance brakes' let alone tell you what is needed to accomplish this. Let's try:

Two things are mostly needed for 'better brakes' (appearance aside) and they are this; more torque and better thermal management. Period. That's it. All there is. End of story. Huh?

Torrque can be made a number of ways; rotor diameter, piston area and pad CF.

Thermal management refers to the capacity of the rotor to absorb and disipate heat in a manner needed by the appication.

So, looking at brand X parts (any part you'll see in a minute) that is the same size as a stock one removes the toque question. And only if it's proven has more mass can its therrmal capacity increase.


So, why do all those horid things to a rotor and call it 'performance'? Aside from a selling point, the primary thing is 'enhancement' of the stock system. Yes, gas slotting or drilling will put fresh pad in contact with the rotor faster. Maybe holes will push a bit more air. and the combo of the two is overly redundant....But all of this comes at a price that is VERY anti what is stated above. It will NOT prolong the life of the part andit will NOT increase the braking capacity of the system and it WILL lead to premature wear and cracking of rotors if filled with holes.. In fact if it is also outfitted with zoomy brand pads of higher Cf it will be very counter to what is being asked for. The higher Cf means more heat, the rotor will become saturated and brake fade will occur. Yes, perhaps not as fast as the bone stock parts. Stil such upgrades are a stop gap to larger parts made for such tasks. (part of the above issue on fade as stated)

There is NOTHING wrong with such parts they have their place in this world too. They are just not quite the level that marketing hype will have you believe. That's ok, just understand it all before you place an order expecting real racing level parts out of modified street ones.

I'm impressed with the written verbage more than the parts from a business point, I like the 'mil spec plating'. I'm filing that one right next to 'aircraft quality aluminum'.
