[s-cars] pad wear-Porsche calipers

[Michele_Deltergo at KeyBank.com]

Ted,
on a fixed caliper, centering the rotor IS key.  If centered, then uneven 
wear as Lee describes, then he has an issue. On some of the early S car P 
car swaps, the caliper was off about 2mms to one side and uneven wear was 
the norm, can't say on the C5 cars.  I have the Boxster S on my C4 and 
wear is very even.

Rotor centering shouldn t matter, as the pistons should float to track the 
rotor unless they re bottomed out or the piston seals (not the dust boots) 
are sticking.  The pads are different, only because of the chamfering at 
the edge to prevent squealing.  You can just grind/file a chamfer when 
swapping the pads.  Wear a mask!

When you do this, make sure the pistons are able to move (not seized), and 
also check the tube that connects the inner fluid reservoir to the outer. 
If this tube is crimped or blocked, the outer pistons won t get full line 
pressure.
