That's the boys right enough.
Well, I know for sure that the Magura website doesn't include these in their present service manual section - but further digging produced a 2003 manual which did...
There doesn't seem to be much difference from HS33's - it says that any differences for either HS11's or 66's are highlighted but it only seems to be the adjustment screw for the pads?
There are probably people on here who know how to do it easier or quicker though.
BTW - you should only need to bleed them if you've shortened / swapped hoses or have a leak - the Magura Royal Blood doesn't absorb water like DOT fluid so its pretty much bleed free in regular use.
Also - if you need any special bits for the bleed, ie barbed fittings etc, Tarty Bikes have a good selection...
Hope this helps - if only a little.
This ain't no party! This ain't no disco! This ain't no foolin' around!
