g'day thrillseekers.
I am the happy (?) owner of an EF. I was wondering how many of you have the same problem I do with my front disc rotors warping. It is getting to a stage where I am thinking of running two sets of rotors, and getting one set machined and changing them at each service. I know the technological reasons for the warping, i.e. different bearing centers (compared to XA-B-C etc) and different stubb axles, but what am I doing wrong to have my rotors warp within 3 or 4,000 ks of having them machined?
I have even taken a tension wrench to the wheel nuts to make sure they are of even tension, but that didn't work either.

Wheel bearings are always checked and adjusted correctly, even used a tension wrench on them but to no avail. I am currently using Bendix pads on the front, but never again, as they are very dusty. I am using Hardly Ferocious on the back, and they are very good as far as dust goes.

But I digress. Can somone out there shed any light on the subject/problem?

Try reading these articles;

Disc Thickness Variation

and

Front Wheel Bearing Adjustment EA-EB Falcon,
which I would suggest applies to all E-series cars EA thru to EL.

Are you sure you have adjusted yours correctly?
How heavily do you brake?

Why dont you fit a set of after market DBA rotors as they will hold up better than the originals.

have you tried new rotors or do you keep getting the old ones machined. like six_in_a_row said try some new DBA's.

i thought rapid cooling and heating was what warped the rotors?

EF rotors are absolutely crap, without beating round the bush. They continously warp, and wear down very quickly. First thing I did to my Falcon was replace them with some DBA units, and went for Bendix Advance pads. I cannot recommend these pads highly enough, they are fairly new, they dont squeal, they dont leave a spot of dust on my mags, and they dont fade. The rotors dont warp, the brakes dont fade, they pull the car up very hard very easily, I love them.

You can check out the guide I put together after I installed them at www.geocities.com/polar988/rotor1 for a few ideas, if it helps. The whole thing cost me well under 200 bucks, I also highly recommend spending 40 bucks and replacing the front bearings too.

Any questions on what I did, please contact me, love to help out.

Cheers............ Tim

I am using DBA rotors now, and I have read the articles RAPTOR has mentioned. I like to think that my braking is usualy light to moderate, I don't usualy roar up to a set of lights and slam on the anchors. The wheel bearing were replaced when I replaced the original (standard) rotors. I have also spoken to DBA and they cannot offer any other solutions. My next effort is to try either the Bendix Advance pads or the new Hardie Ferodo ones that I can't think of the name at the moment.

Thanks for the suggestions.

I am also going to replace the rear rotors too. They are very close to undersize, if actualy not. These are being replaced by DBA's too.
