Hi All

  this is the first time I'm doing the front brakes on my 190.  A quick
inspection revels the caliper assembly to be quite different from my 300e.
The 190 appears to have a floating single piston caliper.  Anyway, do I need
to remove the 19 mm nuts top and/or bottom, or do I simply remove the 13 mm
top and/or bottom nuts that have the rubber bellows over their shaft.  
I'm guessing that removing the 19mm nuts will remove the complete caliper
assembly, while the 13 mm bolts will remove (and/or swing up/down) the moving
part of the cliper and then give me access to r&r the brake pads.

 any pointers much appreciated

cheers, guenter
