Post track day brakes question
I did Croft ast Sunday and the brakes held up just fine. Driving home they brakes were fine too (65 miles).
Whilst they are still performing fine they are now making a humming noise (I say now, this was Tuesday, I havent used the car since). All of the diagnostics through I Drive say all is well (green). Im gonna pop the wheels off to look at the pads, my question was are the I Drive readings reliable and what is the likely cause?

I also got some pad transfer on my rotors after the track, the symptom being some brake shimmy. I'm going to drive it a while to see if it wears off, if it doesn't get better I'll get the rotors replaced. I did not experience any brake fade during the entire 3 day weekend.
Brake Ducts seem like the appropriate fix for this in the future. I hope someone develops them soon. SFBimmer is correct, Idrive only measures brake pad wear, it's not going to give you any indication of problems with vibration in the brakes.

No vibration or shimmying, just a humming noice when braking. Wierd.

This has happened to me twice now. The first time, it went away in a couple of weeks. The second time, things are getting a bit better after a week, but we'll see, which suggests it might be uneven pad material transfer. Would using track pads help?

Yes, track pads would help as they are more resistant to the heat and won't melt to the hot rotors.

just ordered Pagid Yellow RS 19s from Turner, since I will be in Laguna Seca for 2 days this weekend - I will post the results after I have used them.

I use the OEM 18s for track, the Breyton 19s are for road use.
