Brake Fade

[CedricN]

What's the status on the calipers, are the pistons moving as they should,when were they rebuilt last time? Even a tiny little sticking will cook any pads, one of the most the most important bit to have in order on a track car. The more you heat them up the faster the rubber seals age.

I am surprised at the disdain on this thread for the DS2500 compound. I have never ever had fade with the DS2500 pads and I have tried really hard, ok I may be just a crap (slow) driver but my experience is positive. My only complaint is dust, lots of it.

As others have said try a harder pad or maybe adjust driving style slightly

Same, I had 2500's on my Subaru (so not a light car) with AP 6 pots and they handled the stress easily as well as the CL RC5+ things that I had in previously, but the 2500's didn't have a hateful squeal firing clouds of dust out every time I touched the brakes.

My non-expert suggestion is maybe that your disks still had deposits on from the previous pad compound which was 'incompatible' with the 2500 compound, so you got less than perfect brake performance. You may have weathered the storm now, so maybe you'll get better performance next time out.

Edit: Just re-read and noticed you changed disks too, so that's my suggestion out of the window. It may still be a bedding in issue though.

Thanks for the additional replies.

The calipers were both recently replaced and I give the brakes a good service one a year so they were all moving freely. I'm not sure what it was, but something in that Pad/Disc/Track combination didn't work out well.

I've decided to not go too radical but incrementally make everything a little better. Slightly larger (20mm) and thicker (1mm) discs, slightly larger calipers, a bit more cooling and slightly more aggressive pads.

I'm confident that will give me a little more reliability and a little more braking power too. Cheers

2500 are ok for the street, 3000 are a harsh racing pad, eat discs and squeel and need heat to work. I use ds Uno but I have heard good things about 1.11
I settled on Unos, brilliant pad.
