excess rear brake dust

[slyphen]

For some reason, i have a significant amount of brake dust build up in the rear when compared to the front. This started when i installed SS brake lines, replaced oem brake fluid with RBF600 and started using Ferodo DS2500 pads (Front and rear). Not even sure if its an issue. Car is handling fine after a full Autocross season and several track days. Should i change the rear pads back to OEM?

I've also turned off TC to see if its because of the ECU freaking out with my suspension and tires, but doesn't seems like its making a difference.

Check to see if rear calipers are sticking. Inspect rear pads.

If you aren't doing the pedal dance your TC is still trying to "help" by using the rear brakes.

Get some more coaching and seat time, TC is subtle as a hammer in the '12-'16 cars except for the brake biasing. Could be that but I doubt it because DS2500 shouldn't survive hot lapping unless you're well under the limit.

@N1rve is right, check for sticking caliper, clean everything up and keep an eye on it.

I briefly looked at your build thread and I see you run STX in your avatar. I have no idea what is allowed in STX but check out the beastronix 86nanny. The 86nanny does the pedal dance at the flip of a switch.

I dont think it has anything to do with my driving. The car is also my daily, i'm getting dust from just high way driving. i'll check for sticky caliper again, but last i checked, rear hub was able to spin freely.

Thanks

Yeah than the TC/pedal dance isn't going to change anything unless your high way driving consists of you trailbraking into consecutive on-ramps for a half hour every day and lifting a wheel off the ground.

It was not obvious from your post whether you are observing the dust due to DD or autox/track.
