Being a newbie to doing my own work i was wondering when do you know when you should change brake pads. I am currently running pagid orange on my 911 carrera with stock brakes. After the Glen i have about as much pad as the backing both front and rear. Also this is the second time my fronts and rears have worn about the same. I thought the fronts always went quicker. the car is now only driven on the track and to and from the track. thanks for the input.

If you’re happy with them run like pads for a while more. The lower run groups (and you’re no longer a part of that pack) tend to burn through pads faster. If you aren’t locking up the rears it could be that the brake lines are bad (not releasing the pads) and causing them to wear faster. Or just an anomaly from the lower group. Don’t listen to anyone about switching over to PF97s your too fast now as it is

The time is now. When the pad thickness == the backing plate thickness, stick a fork in 'em, the pad's are done.
I can't remember whether my experience with stock 88 Carerra brakes and pagid orange pads was that the fronts and rears wore equally quickly. But, I wouldn't be surprised if that were the case.

I replace them well before they get to the point at which yours are, but i go more by brake feel than pad thickness. On my car, when they get get about half way worn, I think too much fluid is allowed into the caliper, where it gets hot and boils, causing a mushy feel. If they don't firm up after a bleed, they go in the trash.

Terry has the right idea. The ”= backing plate” is the tech inspector’s rule and considered the minimum. I also change mine well before that point. I keep the last set as a spare, though I usually compare with the last last set and keep which ever set is thicker the spares. Surprising, all seem to end up about the same.

x 2 on the advice. Also, make sure that you check the inside pads as well. Sometimes they do not wear evenly and you think you have plenty of pad but you really do not.
Finally, I carry extra rotors just in case.

how about the rotors ? Do i need to buy a measurement tool or is that something done by observation also ?
