EOI: Brake rotors and pads

[dan_the_man]

Here's something i pulled off autospeed

AutoSpeed: What are the advantages of drilled discs?

Steve Borg: They dissipate water and dirt, degas the pads (giving better braking distance) and also stay moderately cooler. But that's not an issue - I don't think - for street use. We guarantee our drilled discs to up to 700 degrees C - and they will withstand more than that - but you'd never exceed 450 degrees on the street. On the racetrack you'd probably get up to 600-700 degrees. Again, though, our rotors aren't sold as racing discs. And, of course, our drilled discs look the part - especially behind mag wheels. The slotted discs perform exactly the same and do exactly the same job - getting rid of the water, dust, gasses, deglazing the pads.

AutoSpeed: What are the disadvantages of drilled discs?

They are a little bit noisy - you do get a whirring noise. And, with our drilled and slotted rotors, you do lose about 10% pad life. In saying that, you gain in rotor life because the pad won't bite hard into the disc. If you let the pads glaze up, their material becomes harder than the cast iron of the rotor, and it then starts to bite in and create grooves. But, with slotted and drilled discs, that doesn't happen because you've always got a nice fresh pad surface running over the disc.

AutoSpeed: We have seen several sets of cracked drilled discs - how do you explain this?

Steve Borg: Look, I keep myself fairly fit, but I'd be crazy to jump out of bed and do a sprint without warming up. It's just like you don't take an engine and go racing without warming it up. It's the same for rotors. They're cast iron, they expand when they get hot, and you really need to warm them up before working them. Abuse them when they're cold and they'll crack. You don't have to warm them 'till they're red hot, so long as the heat sink is right through the rotor and it's not just the outside surfaces getting hot, it's fine.

any news yet on these?

[LazyZed]

Are these rotors compatible with the 300zx z32 TT front calipers by any chance? If so I might be interested depending on my currently poor financial situation

Cheers

sorry, no news as yet....will get in contact with dsturbd on monday

[SeriesIIGTST]

rob, i'll ask bart if he can get them and at what price. Just looked at the dba website and they do list rotors for the z32 TT so I guess it's possible.

[bossplaya]

should do a group buy on some good brake fluid at the same time

[R33 Impul]

Is this goin anywhere?

[SeriesIIGTST]

I have PM'd dsturbd several times but looking at his profile, he's not been online since 9/5/04. I only know him through online chats so I can't really move this thing forward any more than its going. Gives everyone some time to save $$$ i guess. I'm still in need though...

*****WA ONLY SORRY******

Hi all,

One of the forum members here in WA, Dsturbd, has kindly offered to hook some members up with a great deal on brake components, in particular DBA 4000 slotted rotors and matching performance pads. I know i'm in need of some and a few people have also expressed a casual interest so I figure a group buy may be in order.  

Pricing has not been confirmed yet and obviously depends on numbers but bank around $250 each rotor and $65 for a set of pads. (Purely guesses)

If you are interested, please note your interest within this thread. I'll post more info on products and pricing when available.

I'm interested, let me know how your progressing.

Products:

DBA 4000 series Slotted rotors (no cross drilled as they tend to crack)

Bendix Ultimate Pads  

Green Stuff Pads

Has anything else been heard about this lately? As my car will be off the road for the next week or so I thought it would be a good time to change mine over to the 4000 series.

[SeriesIIGTST]

Brett, heard from dsturbd on Wednesday who has been on holidays for the last little while. He said he'd have prices up on Thursday but so you can see, haven't seen anything as yet. I sent him another PM yesterday. Trust me, i'm on to it as much as i can.

[SeriesIIGTST]

Prices are in!

$245 for 4000 series rotors

$45 for bendix ultimate pads

$230 for greenstuff pads

$180 for feredos pads (which dsturbd tells me are better than greenstuff)

$65 ltr for Elf brake fluid

If you would like to acquire any of the following, please PM dsturbd directly and he will order and arrange payment with you individually. Just mention the SAUWA group buy and he'll give you these prices.

Cheers!

[MrGTST]

So whats the next step.... Do we need to gather all the money together and pay in one go to gain the cheap price???

Tell us what we need to do!!!!

[Driver]

[SeriesIIGTST]

Brett, awaiting further instructions as to payment, collection and availability.
