back to those pesky PCCB wear indicators
these are my rears after yesterday
what's the consensus on these? A-ok? or should i be worried? have got 13,000 kms (about 8,000 miles) on them. 2nd set of pads, stock.
note the above pics are of the SAME rotor, just different indicators. they don't look the same shade because of the angle.
the front indicators are hardly visible, which is not surprising as the rears are supposed to take more abuse than the front rotors.
so am i just overreacting and i should be fine?

Mine are essay past that stage.
When I asked my dealer about them, they say that when the surface area of the little circles are more than 50 % gone, then it time to replace. Howevere I'm past that now, and still going strong on track.
Get the rear brake cooling ducts, that will ease the wear rate a little.

interesting too though that the min thickness of the rotor is clearly stamped on there. which suggests that determining pccb replacement is some combination of the wear indicator and rotor thickness?
plus maybe i gotta gut some chickens and read the entrails!
damn Porsche, why can't they just make things simple and straightforward!

thanks! that's useful info.

As you, my fronts are fine, but the rears are taking a pounding due to so much rear bias, and less cooloing effect.
I may change my rears to steel at some point.

Although the rears don't get nearly the punishment that the fronts do in full deceleration, the rear's get abused through PSM management. The rear pads/rotors are often overlooked and do take a beating especially on the track with PSM, and most drivers don't even know it.

Even with TC switched off, the ABS/ABD ? seems to me messing with the rear brakes.
