Warning light says its time for brakes on my 2005 C2 MT6. 56,000 miles. Zero track time.  I pulled the wheels here's what I saw:

  • Gray Brembo calipers. Fr: 996.351.425, Rr: 996.352.421
  • Uneven wear at the front, both L and R. ~20% remaining on the outside pads, 40% left on the insides. 
  • ~80% remaining on all four rear pads
  • Front pads are Textar T4045 FF (46P). Originals? 
  • No cracks observed in rotors
  • I m pleased with brake performance in terms of initial bite, fade, and noise. If it weren't for the outer front pads I'd be good to go for another 10,000 miles or more I expect.

 

Questions:

  • Your thoughts re: uneven pad wear at the front
  • I had planned to do all four corners... Any reason not to simply remove the 1.5mm "lip" on the front rotors, load fresh Textar pads and bed them in? Maybe rotary brush the rotors to clean the old pad layer off (I've seen Edd China do this).
  • Is a fluid flush any more than an extended bleed session? I usually bleed until I see the fluid look clean(er) and clear(er). I prefer not to have to bleed the ABS.
  • Any reason for spending $$$ for Motul fluid on a street-only car? I have no idea what fluid is in the system now.

As I recall when I replaced front pads they were not evenly worn either but can't say what impact, if any, it  had on braking performance As for the lip, wear limit on the disc is 2mm, if  lip measures 1.5mm now it would make sense to me to replacing front discs while you're at it. Not sure it would make financial sense to them turned even if you could find someone to do it these days. As for brake fluid , I use Pentosin Dot 4 in my '07  as it is Porsche recommended.  Brake fluids designed for track use have a higher boiling point than those formulated for street use and as such aren't necessary for street use in my opinion. Good article from Hemmings web site on brake fluid below.
