Just curious when you decide to change your brake pads. I have 4,500 miles on the 3 including 11 track days. I am running at the front of group 4 at the DEs, so am hitting the brakes pretty hard.

Are you waiting to replace your pads until the indicator light goes on or should you replace them before that? Also, when you do replace your pads, are you replacing all of the parts like the dealer suggests / does or are you just replacing the pads?

I did not wait for the indicator light. I replaced just the pads. What other part(s) is the dealer recommending for replacement?

replace when 50% of pad material is gone if you are hard on the brakes...you are probably overdue

I'll have to look at the invoice, but they included sensors, caliper bolts, etc. The dealership claims that they replace all the parts when they replace the pads.

Where can I find a DIY to show me how to do the replacement?

Andrew D.

I believe the sensors only need to be replaced if they have been triggered but I suggest you research it further. I don't know about the caliper bolts. RennTech dot com might be a good source for DIY.

+1 if you wish to save your rotors.

Strange. when I go to RennTech.com, I get routed to http://verveakarally.com/.

I just figured out that it is .org

Porsche recommends replacing the caliper bolts when replacing the pads.

Can you reuse them? Probably, without any problems..... Do you want to take that risk to save a couple of dollars? Probably not.

I replaced mine the first time at around 2,500 miles and they were about 50% so my guess is that you are due. Better safe!

was this PCCB?
All: what is avg life mileage on PCCB pads for you all? and out of those miles what % is the track/street? TIA

zmann

You can see my answer above and it seems, according to the crowd here, that I am overdue.

keep in mind that he is tracking about once a month and the 50% rule is for track use...if just for street I'm sure you could safely use the pads longer

Brakes are your insurance!
When they fail it can not so fun....

Sorry. My bad.

If you know how to replace pads yourself and you inspect them after each run at the track, you can wear them just about all the way down. However, the brakes will get mushy (more fluids in the pistons) and there is less materials to insulate the heat which in turn cause your fluids to boil a bit quicker. All in all, tracking is an expensive sport so you should be prepared to replace brakes and fluids rather frequently. You need to keep your eyes on the rotors too. The reason they replace the sensors is because it is very easy to break them when you take them off. So the factory manual says replace them rather than have the dealer explain "sorry we cracked that so we have to put in a new one." As far as the bolts are concerned, they supposedly stretch over time. Although I would probably only replace them when I replace the rotors, not when I replace the pads, if at all. The torque on them is only about 67 lbs. The torque on your wheel bolts are 90-95 lbs. It they can't make a bolt that withstands 67 lbs, I have to be wondering what kind of bolts are they. Maybe it's thermal stress.
