Safe brake pad thickness remaining for track day? - Page 2

Check between each session if you’re gonna be running it close ... also consider using a mirror, inspection camera or jack to check the bottom of the pad.. for some reason my pad recently indicated 4-5mm at the top but I was about to change for back to back track weekends and wanted some fresh pads... glad I did because I found the bottom of the pad was down to the backing plate. Front right wheel keeps doing this for some reason and I didn’t learn my lesson the first time ... did 4 track days on “track day pads” and went down INTO the backing plate this time destroying the rotor. Full set of pads in 4 days (2 at Pitt race, 2 at NCM). I’m also going to look at a different pad...

I would say if you can’t answer the question yourself (as others mentioned it more often skill and track dependent) then either:
1. Have a spare set and change trackside if you are willing and able
2. Just change them, you can always put the old ones back on and run them out on the street.
