Is this brake pad still enough for another track day?

[BA939P]

I've been using this stock brake pads over the past three track days n last year, but I'm not sure if it's still enough for another track day.
It would be great if anyone who's more experienced could tell whether it need to be changed before next track day. Thanks a lot!

That’s pretty tough to determine on a picture but it looks like you are getting pretty close. How aggressive do you brake? I got 8 days out of my stock pads but I didn’t really start getting aggressive on the brakes until the 3rd or 4th track day. If it was me I definitely have an extra set of pads so I could swap at the track. You might be better off installing new pads, bed them in and then switch back to the original pads for non track driving.

Every time you go out, the confidence rises, braking later and more aggressive..
If you are driving the same (slow) as your first time out... then it should be ok..

Do you want to run how you want or have brake pad concerns that will constrain you..?
In all honesty, it can only be your call. Thinner pad, more heat, more wear...
I wouldn’t trust any advice on here about stopping performance.. too many factors to consider and too many unknowns..

Good luck and be safe.

The brake pad material helps provide thermal insulation from the steel support shoe, piston, and piston seals. The seals are like your nuts, protect them at all costs and avoid thermal exposure that might require replacing one....

7-8mm remaining might be pushing it.
If you are NOT running SRF or other high temp brake fluid, I'd be especially shy of deep braking below 7mm pad material (not including metal support shoe thickness).

TMO forum I think had some users experiment with pushing the limits with poor results.
Keep in mind those exploring limits might be running titanium thermal shims and SRF or better fluid...

Thanks for your suggestions. I'm currently running motul660, but gonna replace the pads before the trackday.

I brake quite hard on the track, so i will get a set pair of brake pads. Thanks!

Good call.

Judging by the thickness of the backing plate and typical pad friction material thicknesses it looks like you're getting down close to the 50% friction material thickness guideline that many track day entities follow at tech inspection.

Keep and eye on them after each session and when they get down to the min thickness swap in new pads at the track.

I did my 3rd track day with my pads looking just like yours. At the end of the day, the pads were right even with the scratchers. Minimum thickness for all 4 pads was 3.5mm. So I'm consuming about 3mm per track day, and they last 3 days.
