When I changed my brake pump I used traditional way but it was impossible to bleed. Do as skapan says above.Try the traditional way, if you get a hard lever try it on the street to make sure it's ok. If you have any doubts then either let the dealer do it or get a GS911 to exercise the ABS pump while bleeding.
i have used the traditional method on both my 20 and my 18..... It works fine you just use more fluid since the pump also contains fluid.i've never dealt with an abs bike before. Is there anything special to bleeding the brakes? My brake fluid reservoir was broken, so there's quite a bit of air in the lines.
I just replaced pretty much everything, so started with empty mc, lines, calipers, etc. I pushed through a bottle(only took 1/3 bottle to fill the lines) using the 'traditional method and was bubble free. Doing the GS911 ABS pump gizmo, purged plenty of bubbles, so I would say that if you have potentially introduced air into your system doing this is Probably essential, if you are just replacing fluid then probably not.i have used the traditional method on both my 20 and my 18.....
