disk wear?

[Bill]

Dear Jim, Jean and Mike (and others),

Jean:  I am the second owner of this machine and think the mileage (43K) 
is correct.

Jim: I have used Spiegler before for stainless brake lines, I will check 
out their "conversion" process.

Mike:  What you say about sintered brake pads may be true.  I have not 
replaced either pads or rotors since I've owned it.  Bud Provin is a 
good guy, he was my go-to guy for keeping my K-bikes running great while 
he was still at Bob's.  I am not locked into OEM but I noticed that the 
original left and right had unique part no.s (34 11 2 316 067 & 34 11 2 
316 067).  What seems to be the superceding part has one number (34 11 1 
454 612). _Does that seem right?_

Any other suggestions for aftermarket rotors?  EBC?  My riding style is 
mostly "smell the roses" (not a racer by any means) if that helps.

Thanks, Bill Bachman
