Cross-drilled rotors crack, period. No matter if they come cross drilled from the factory, or if you custom drill stock rotors, they will eventually crack. Even Porsche rotors crack under heavy track duty. Plus there's really not much benefit to be had with cross drilled ones. The Brembo blanks should work fine.
In a world of compromise, some don't.

Benj,

I think your right at a certain point. I read in one of the articles of Sports Compact Car (forgot the frigging issue) that cross drilled brakes do crack but depends on the diameter of the holes. Also, the example you gave which is the porsche with cross drilled brakes only happens on "heavy" track days...meaning 10 to 15 laps continous. I dont think most of the cars here would really punish their cars to that point.

I recently had my OEM disc cross drilled and I must say it did improve its performance. I tested my car from manila to calamba/ star hiway on the same day back and forth and didnt encounter any problem. It really depends on the diameter of the hole you drill, the bigger the more probability it would crack. But if the drilled holes are just right it wouldnt damage your disc.

Also it depends on the drills used, low quality drills will leave imperfections on the drilled surface creating imbalance heat distribution thus creating cracks.

The real use of cross drilled brakes is to assist you in cooling off your disc at a shorter time. And it did cool off my disc at shorter time.

Once I have the time ill post the picture of my OEM cross drilled brake. Hehehe mukhang brembo dahil I painted the caliper red.

Hope this helps.

How different is dot4?

I just got the dot 4 brake fluid of bendix and Im wondering how different this is from dot3 aside from the high tolerance for hi-temp.

better pedal pressure? etc?

Anyone?

thanks!

If you don't race or do tortorous downhill runs, you won't see the benefits of DOT4 or better brakefluid.

And you still have to change them every year to get the best feel / performance since higher rated brake fluids tend to be hygroscopic, i.e. it absorbs water or nagtutubig after some time.

As for pedal feel, it doesn't depend on the DOT rating. I'm using ATE Super Blue DOT4 and pedal feel is firm. Another good brand, MOTUL RBF offers a relatively soft feel and is also DOT4 rated but actually exceeds DOT5.1 wet and dry boiling point ratings.

SS brakelines will help reduce fade as well and give consistent pedal feel under duress.

question,

If i were to buy brembo rotors should i change the calipers as well?

Edwin,
i also had my oem rotors cross-drilled, and you're right.. my mechanic told me it depends sa dami ng holes and the diameter of the hole..pulido ang paggawa sa machine shop walang sharp edges sa bawat hole so as of now it really cools off the heat. I'm just alarmed with what these guys are saying... nakakatakot nga ang experiences nila and they should know best kasi they have first-hand experience. I'm planning to buy brembo rotors sa HRC pero i haven't asked pa kung meron sila for B16EF rotors front and 92 civic discs rear. pero this is my last priority, kung may budget na ;D tutal daily driver lang sha..i won't race my car (not yet  :P) til its in tip-top shape..and if i have all the goodies na  ;D

Im using slotted rotors with stainless steel brake lines for now. Stock calipers.

So you think I should stick to dot3? No use ba talaga dot4 in terms of daily driving and hard braking ( from hataw hataw) once in awhile?

Aside from the dot4... Im also geting some EBC Greenstuffs.

In a worst case scenario, should I ignore and waste the dot4 and buy another liter of dot3.. or do you think I rather use dot4 I just bought?

Do you have any feedbacks with Bendix Dot4? Its the one I have and it says it can tolerate 500deg. I know you only get that hot through racing and all.

Let me know your opinion on this pare. salamat!

Meron ka na eh, gamitin mo narin. :) I've seen the Bnedix brake fluids, pero I have yet to try them, though gamit ko yung pads nila and mukhang OK naman eh.

I'm about to order some DBA slotted front discs for my Civic. This should be a lot better than the stock discs, and they're not too expensive either.  :) These combined with good pads will be a big improvement.

Wala bang issue yun? Nothings gonna wear and tear faster? can the stock master cylinder and all other parts take it?

I dont know much about this. Somone just told me to stick with dot3, kasi baka daw may bumigay sa brakes ko. I dunno if hes just trying to be a smart ass. ::)

salamat!

Wala naman, since hindi ka nagpalit ng calipers, hence you are not asking the master cylidner to pump more fluid.

Yeah I think whoever told you that must have passed on the wrong information. :)

on the track IMHO SS lines are a better upgrade than using dot4 fluid.

Changed to dot 4 fluid and my brakes still faded...although not as much as dot3. And they faded in such a way that you can easily anticipate the pedal travel/mush thus break earlier b$ entering a turn.

Recently had SS lines and since the availability of Dot4 was is quite scare, i just used Dot3.....went back to the track..and the brakes hardly changed after pushing my brakes.

Was just wondering how they would perform with DOT4



Enigz na lang for short
