[s-cars] Front rotor wear

[Peter Golledge]

Douglas,

For monoblocks the pistons themselves serve as the "float" so it is 
likely a piston is binding on one side.

I've got a set of these on a 5000 (yep a somewhat modified example) and 
since they don't get used other than track days I've had them bind up a bit.
