About 10,000 miles ago, I swapped my stock rotors for a pair of Brembo Cross-drilled and slotted rotors and some EBC Green Stuff pads, trusting these brands would not do me wrong. Now the rotors have numerous cracks at the drilled spots (more than just surface cracks) and seem slightly glazed. My driving could be described as spirited. On weekends I often brake hard after reaching 150+ on open roads around my home, and sometimes do mountain runs with buddies. This obviously is hard wear on the brakes, especially since I'm usually keeping pace with the local sport bikes, but I didn't expect this from Brembo. Could there be something wrong? Am I expecting too much from them? Are there any better products I could look into involving just swapping rotors and pads? I'm not looking to do a Big Brake upgrade at this time. Give me some ideas.

 

Brembo is a good brand but I've heard they don't cross drill or slot their rotors. People buy their blank rotors and have them cross driller and/or slotted by a shop. If this is done wrong, problems like cracking can occur. SO this more than likely isn't the fault of Brembo but the fault of whoever did the machine work on the rotors.

This is all hearsay though, I have no personal experience with Brembo rotors that have been CD or slotted. I have had Brembo blanks though and they were great.

 

Brembo blanks and then machined by a shop, same thing i've heard too. Get some good pads, Brembo blanks and good brake fluid (make sure it wont damage stock lines) and that will be a much better improvement.

Do you have discs on all 4 corners or only on the front?

 

Rotors only on the front, it's an LX model. I'd like both a cosmetic and a performance improvement. I know cross-drilled are notorious for cracking, should I just go with slotting them? Or would it be too difficult to get them machined properly?

 

Also, on the note of 4 wheel discs, anyone know if someones got a tutorial for swapping the rears from an EX Accord?

 

i've been looking for the same tutorial. good to see another drive out there beats the ever loving crap out of their 6th gen accord.

 

cross drilled rotors have always been synonimous with cracking. your better off buying regular rotors

Do a search there's even a finely detailed one with pictures AND shop manual printouts for a 5th gen accord, I bet you could do it yourself with all of it

Brembo blanks+all disc+good brake fluid+good pads and you'll have it much better.

People dont understand that big brake kits mess up more than they help, they have to match the rear brakes, need to upgrade master cylinder, etc....

 

Firstly, if you are travelling at speeds of 150 mph on weekends etc... you need a real upgraded 4 piston brake system which will run you upwards of 1000 dollars. You can get brembo blanks that arent crossdrilled or slotted and they will fail also, they just arent made for that kind of driving, wear and tear.

If you are taking the car to excessive speeds, you need a real brake system.

Very true Brembo doesnt make cross drilled and slotted. They make either cross drilled or slotted only. You bought the wrong product. You can't say Brembo fucked up. It is not their fault.

Depend on where you get it and what brand. I have cross drilled Brembo for a years now. No problem at all. They performed much better than stock blank rotor.

 

The only rotors that are crossdrilled or slotted by Brembo are part of their big brake kits (if they're even drilled or slotted to begin with). As already mentioned, 99% of drilled/slotted Brembo rotors started off as Brembo blanks, and then some other company drilled/slotted them. Needless to say, this really screws with the strutural integrity of the rotors.

accordselux already mentioned the optimal setup.

 

there was a write up on it in an issue of honda tuning about a year ago, as well as a few detailed writeups on accordinglydone.com

you dont need cross drilled/slotted even for uber aggresive daily driving / autocross....just isnt neccesary

as said before:

good pads and fluid on stock rotos &gt; cross drilled

6th gen. 98-02. the one after the 5th gen. the first USDM only accord. the one with the big fat ***. how else can i say this?

it just seems like in all the websites and all the mags they to forget that there are poeple out there who drive these cars and want to do stuff to them, and they are NOT the same as 5th gens.... at all. totaly different. complete design change. re-engineered from the ground up. nothing mirrors. no shared parsts. fresh to the line. seriously different. etc....

Exactly...oh and don't forget stainless steel brake lines for those 'sprited runs' .

What I had on my accord was this:

Brembo Blank rotors
Axiss Pads
Stainless steel brake lines
and flushed new dot 3 fluid

She braked like a champ and still does .

 

brembo does though make cross drilled rotors for most of their blank applications. its in the brembo catalog, i have them as well direct from brembo. the people that sell the cheap brembo crossdrilled rotors are the ones who buy blanks and have them drilled.

Just to clear up when people said that there's no brembo crossdrilled except for the big brake kits.

 

you got the info you needed, unfortunately stupidity also cracks more than rotors

150 + on public roads = ignorant

thinking that car can do 150+ is just about as stupid
