Here is CSG spec pad. Even transfer layer, pretty even rotor contact.

Thanks for sharing. But they are not the same pad and rotor than the ones I have.

Are you saying Antilock brake system did this to the rotor? If yes, I disagree totally. I think you are confused with ABS and TRAC/VSC.
Usually Trac/VSC interference will show up on the rears. I've had the TCS overwork the rears when I didn't have the car warm enough to pedal dance. I personally, haven't seen it on the front, not that it isn't possible.

This is the CSG C1 pad on a stoptech BBK with 328mm rotors. Much different setup.

that's not a problem, as you're going to be changing pads and rotors soon anyways!

I do not really care that you disagree. I am not confused and have been through 5+ sets of dtc on this chassis over the years. Your rotors are fine. DTC pads sometimes deposit. It doesn't affect anything other than triggering rich csg pad owner who swear deposits are a negative thing while it's not really

deposits are a bad thing. they create an unpredictable friction surface.

You have been told 1/2 a dozen times.
This is what you want to hear. Replace the rotors with bigger dia rotors and a set of 4 piston front and 2 piston rear calipers (AKA BIG BREAK KIT) LOL BIG BRAKE KIT.

It wasn't that long ago that ABS did not exist.
Back in the day, if you slammed on the brakes, you would going merrily sliding out of control. Happened all the time.
It's one of the best safety features of our time.
So how do you turn it off? Pull a fuse?
ABS prevents brake lockup. It is traction control, for brakes. It is always on, but not always engaged. It only engages when lockup is detected.

For all intents and purposes, there is no reason to disable or turn the system off, even on track, as it is a reactive system. It only intervenes if you've already locked up one or more wheels. It is generally faster to leave ABS on, and to judiciously use the system only under circumstances where traction is uneven. (e.g. left tires have way less traction than right)

ABS comes with a LARGE heat penalty when used.

He just needs to get better pads. No need for a BBK at this time.

Nope


This happened because the pad is completely insufficient for your use. You need a better pad combination.

It is neither.
If the DTC works for you, stick to the DTC. It doesn't work for everyone.

If you think deposit are NOT a negative thing, then you should check out your own data. You'll very quickly change your mind when you see how it affects your braking ability.

Haven't said anything about the dtc working for anyone or me, did I.

My data says that OP level of deposits have zero impact on braking, unless there is pad contamination.

But you have been through 5 sets of them I'd assume if you were not satisfied with them that wouldn't be the case.

I personally don't consider that level of deposit or difference in rotor heating alarming. I just wouldn't buy that combo again if it was me but I'd continue to run them till I wore that set out.

As for your goofy comment on "rich" CSG pad owners. Are they really more expensive if they last longer? XP10's at 500 a set lasted me maybe 60-65% of the life of C1's, not to mention the XP's suck. I am running Raybestos this go around, will probably try something else the next time variety being the spice of life so they say.

Sorry, that was rude and uncalled for.

XP10 were awful to me too.

5+ sets on this chassis, probably 30+ dtc sets total. Hundred+ of sets from other brands combined...dtc are very high on the scale of performance and life per $.
