Just for fun, a view of the old and well-worn OEM calipers next to the new ST-41s.  Luckily, the finish on the StopTechs will never take on the old 'n rusty look of the factory units.
 
 
Filling the system with some fresh Motul fluid.  While a more common fluid would be adequate for around town, we prefer the high-temp abilities of the Motul.
