Brake rotor wear limit

[acadian_dad]

My 987 service manual refers to checking rotors against the wear limit specifications in chapter 461000 "Technical Data / Brake wear limit" - but this chapter appears to be missing from my copy of the service manual ...

I found a reference on Trygve Isaacson's excellent write up on Boxster brakes that the fronts (P/N 996-351-405-01 / 996-351-406-01 ) are 28 mm new / 26 mm service limit and the rears (P/N - 987-352-403-00) are 24 mm new / 22 mm service limit - but I have not been able to find any official Porsche data. Can anyone confirm Trygve's numbers or suggest where I should look ?

The car is a 2006 Boxster-S, standard (not PCCB) brakes.

Thanks in advance

I found those same dimensions for a 986 at http://www.cannell.uk.co

I think the link you meant was http://www.cannell.co.uk/Manuals.htm - wow that's a nice resource - thanks !

Folks - please be careful with these "free" manuals they are many many supplemental updates behind.

Too true ... I have the set from Porschelibrarian ... but it is missing chapter 461000 :( Which contains the technical details for the rotors.

Sorry I had the URL mixed up -- glad you found it anyway.

Loren is right, and there's a reason why the manuals are "free"

So ... measured my rotors today and got 27.3 mm on the fronts and 23.5 mm on the backs ... this after ~20,000 km (12,500 miles) with OEM pads including quite a few DE's. So that seems to make sense with 28 mm / 24 mm starting dimensions.

We'll see how they do when I cut over to Pagid Yellows for the track days ... :D
