Track day brake life?

[transition]

I have a set of Carbotech XP10's that i've been very happy with. They've been through about 5 trackdays now and still look like they have 2/3 of their life left for the fronts and the rears look like they've never even been used. As my driving gets more confident i feel like 2/3's of the way through a 20 minute session that i'm getting a hint of fade. Would switching to XP12's help this at all? Either way, i'm very impressed with the XP10's but wonder if i wouldn't be better suited with an XP12 now or just learn to live with the tiny bit of fade.

Edit: Using RBF600 fluid

Based on your wear, It doesn't look like you're getting fade. When carbotechs overheat, they start wearing very, very quickly.

XP12 will help with fade.

Can you describe your symptoms? Perhaps you're feeling your tires overheating, and the tires themselves are losing grip, causing you to think you're fading your pads.

What kind of tires are you on? Alignment?

I want to say when things start to "fade" the pedal feel is still perfect although overall braking capability seems to diminish. Just feels like it takes 20% longer to slow the car down and the brakes lack that bite that they have when fresh.

Tires are Azenis RT615K. Here's how they looked the day after. I think i still might have a track day or two left before i put on the Rivals.

sounds like fade, tyres look perfect.

Those tires have a ton of tread left. You should see my Direzza II, lol. Rubber is starting to tear on the outside.

I'll have a set of basically brand new Project Mu Club Racers brake pads for sale soon if you're interested. I'm going to sell the BRZ this weekend hopefully.

The DII's were one of the candidates i was considering for replacements. How did you like them? I ended up going with the Rivals for my next set of tires but had to step up a little to a 245/40/17 from the 235/40/17 Azenis. Doing a 2-day DE at Road America so i've been contemplating if i should change the tires before that.

Mu pads are tempting although i've had such good luck with Carbotech products i'll likely be sticking with them.

Car sits more than it drives, lol. I think I'm going to go back to something more boring and winter practical to DD (auto).

The pads and fluid were great though. Definitely didn't feel any fade or sponginess.

They were great when they were brand new. I was basically just trying to burn them up before I got rid of them. I don't think they would have liked me doing donuts on the track

I would have gone with RS3 for track tires as they can handle more heat. Never had experience with the Rivals. I'll be doing the Road America with you at the end of the month. The tires on my Integra are basically gone too, lol. Debating if I should just burn them up at RA or get new tires.

Could have gone for some more drift action.

Excited to try the Rivals - everything i've read on them says at the very least they'll be better tires then the Azenis.

The tires are definitely getting some heat in them.

It's difficult to tell if it's pad fade or tires just giving out toward the end of your session.

Only one way to tell... replace one of them.

Let us know if you want to try XP12.
