I need to replace my rotors, i was looking at BAER DECELA cross drilled/slotted. Before i drop $200 on a set of rotors I wanted to get some advice....

 

1968 mustang? 89 t-bird? camaro? del sol?
Can we have a little help here with what they are going on?

 

you should also consider changing your avatar. That's definitely against TOS

 

lol, I guess i did forget all the minor stuff, lol.. 2000 V6 EX coupe

 

brembo blank or stock


drilled rotor crack

slotted disk wouldn't do sh-t

 

auto zone blanks.

 

Brembo blanks

 

I live in Germany, will the blanks handle the cold weather/ hot breaks on the autobahn?? i appreciate all the advise so far...

 

I'm sure they will do just fine.

Just get a good pad, not something to agresive or it'll tear up the rotor faster.

 

whats a good pad.........and then whats all the hype with drilled or slotted rotors??

It depends on what the car is being used for. Drilled and slotted rotors eat pads pretty quick. I run drilled brembo rotors on my impreza, and have never had an issue with them other than going through pads fast. The only drilled rotors I've seen crack were crappy ones, Brembo is usually pretty good quality and customer service wise.

 

To my knowledge, Brembo doesn't drill there own rotors unless your talking about the upgrade brake kits (rotors and calipers). Meaning that, there stock sized rotors aren't drilled by them but by some machine shop, so unless thats changed then the quality of the drilled rotor is dependent on the quality of work the machine shop does. Like I said though I may be wrong, but that was the last I heard about Brembo drilled rotors.

 

Thats what I have now, Brembo CD.. i got them online but they warped on my...time for new ones...

 

I can say with near 100% confidence, that the rotors that you have on your car right now were originally Brembo blanks, and then drilled later on by some other company, who then sold them as "Brembo cross-drilled rotors". If the rotor wasn't designed for it, the cross-drilling or slotting will weaken the rotor, causing warping and cracking. Slotted rotors are less problematic, but not problem-free.

Cross-drilled and slotted rotors were beneficial with the old brake pad compounds, which gave off a lot of gas, caused a lot of glazing, etc. Cross-drilled/slotted rotors are simply just not necessary for today's pads. It's just that most people still view it as: cross-drilled = greater performance.

Cross-drilled rotors serve more of an aesthetic purpose than anything nowadays.

 

brembo does drill their own...they are sold as sport rotors, along with their slotted counterpart. they do not sell replacement rotors in cd/slotted however. to check if yours are the sport rotors look for a gold color coating on the rotors...it wears off the friction surface but remains on the rest and prevents rusting; the modified blanks sold online will not have this coating present.

 

All cross drilling at slotting does on a street rotor is get rid of thermal mass that could be better used to disperse heat. The majority of people will see no benefit from running them as they will never operate their brakes at a temperature that wouldn't boil the fluid before it gassed the pad anyway.
