I had another day at the track yesterday, and a warning light came on saying I had brake pad wear and needed to take the car in for service. I have only done 3250 kms, and about 250 of these have been on the track. I brake pretty hard most of the time (becuase I love those Cayman brakes) but I wouldn;t expect the brake pads to wear out this quickly. The car is 2 months old!

After letting the car cool down, and washing the car the light has gone off. But I am now worried that I should get new pads before the next day at the track in a months time.

Has anyone been through a set of pads yet? How many kms of HARD driving should they hold up for? How many milimeters should I have left before I need to change them?

Can somebody help me out with this please?

Also, I have some distincting groves in my rotors. A guy at the track reckons that Porsche will probably tell me change these too! That can;t be right? Otherwise I'll be going through a set of front rotors a few times per year? I have only used up about 35% of my tires at the track. You think they would go first?

Thoughts?

dt, i hear you. just did all four pads this weekend at summit point.. though the rears weren't totally used...


i have 6800 miles with about 250 on the track- changing the pads is easy and after a couple go's you could do the whole car in 45 minutes...


if you use track pad and separate street pads you may be pleased with the result.

I've got through one set of front and rear pads and am now about half way through the fronts again. 12000 miles total, of which about 1800 on track. I don't brake particularly hard.


The pads work much better when they are a little but not too worn. I noticed quite poor braking efficiency just before my front set expired - would recommend changing them before the warning light comes on.

How many mm's should be visible on the pads before changing them?

hmmm. interesting. last week i was on the freeway and the same "brake pad warning light" came on saying that it needed service. my car has only 2600 miles on it with no track use as of yet. it didn't go off until i shut the car off and didn't come on again when i fired it up. i have to believe its a fluke. any thoughts?

jax - Probably a fluke, it's pretty darn hard to wear out the pads in 2600 miles of street driving (although I guess anything is possible) unless you are constantly resting your left foot on the pedal while you drive, which I doubt you do. If you get down and take a close look, you can see the pads inside the calipers, if you want to visually check them. If it comes on again, you might want to take it into the dealer and have them check them anyway and reset the computer.

Which brake pad part numbers does one order?

I have been to Pagid and to Hawk and they did not list a pad for the Cayman or am I not asking the right question.

There is another thread I started in this forum about brake pads. They are super easy to change, as mentioned above, can be done in 45 minutes and for pretty cheap.

Porsche recommend that the wear sensor cables are changed at the same time.

I don't know mm measurement, but the easiest thing to do is pop off the wheel and look in the back of the brake caliper and you will see where the sensors slot into a hole drilled in the top of the pad material. If the pad is worn down to where the pad has broken through into this driled hole the sensor wire sits in, then that will trip the sensor and the pad will need replacing. Check one, and if that is miles off that hole, then the rest should be ok. If it is close to the first one, check them all as mine had all worn different amounts.

Don't worry about grooves in the rotors. But check for cracks between the holes.

Is one site that sells pads, but I got mine over the phone from Brandywine Porsche (see the sposors link for contact info) and the service was excellent.

brad, i agree with you with regards to it being a fluke. i hope so. i don't work the brakes very hard, certainly don't ride them. i will check them tomorrow as i give my car a bath. thanks for the insight! a good weekend to all.

Perhaps I am biased (not really)......but I will give you objectivity in my reply:

I had a Cayman S customer who went through a set of stock pads in ONE weekend of track driving - about 370+ miles the pads were GONE.

I'd highly advise to install a set of track pads for track day - and some even just leave the track Pagids on full tie if they can tolerate the squeaking.

Your Pagid brake pad numbers are thus:

Cayman 2.7 = 2407 front, 2406 rear.
Fronts are a bit compromised for heavy track use - rotors are rather small and tend to be a bit on the thin side. Also used on the base Boxster since 1997.

Cayman S = 2405 front, 2406 rear.
These are 996 brakes, nice big meaty suckers that have a nice, high heat capacity.

Pagid Yellows work superbly for track work, and customers have reported 6-10 track days from a set.

You will need to monitor the wear yourself, and the wear sensor will need to be tied up out of the way - but this is not a hard thing to do....

Hope this helps!
