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.

Some will say traditional method is fine. Others say you must get a GS911 to run the pumps.

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.

When I changed my brake pump I used traditional way but it was impossible to bleed. Do as skapan says above.

procedure might be the same but master is different - mine's a Nissin rather than a Brembo, although I'm tempted to swap the 19RCS over from another bike... would that work well?

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 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.

Personally, if i am going to the trouble of replacing my fluid(especially brake) I want to replace all of it.

just my 2c worth

if you're just replacing old fluid, do it the traditional way, starting with brake master.
if you've replaced lines then use a GS911 or an OBDLink to cycle the ABS.

since the bike was on it's side for a while with a broken fluid reservoir, there's quite a bit of air in the system (and zero pressure on the front brake).

I have replaced the masters on both bikes as well with brembo units so that doesn't matter. I also track both bikes and the only breaking issue I have had is the 20rr pads get cooked relatively fast.

I'm planning on installing 19RCS on 2020 model when it arrives. Does GS911 support K67? How do you guys bleed ABS without going to a dealer?

i have never used any GS911 on my 2016 or 2020. I changed the break fluid to DOT 600 so i empty the hole system and refiled it. I have never hade any problem. to get the last air out of the system pull the break in all the way than zip-tie it in that position. Leave it for at least 12 hours after that bleed once the master cylinder pump (open and shut) then cut the zip-tie, pump up the master break cylinder and you are free of air. ( the air will raise from the pressure over night to the highest point and will wait for you to set it free :) ).

But did you lay your bike down on it's side for a while like the OP? No, didn't think so. He might need more than a simple bleed and a zip tie to get his "breaks" working.

if he did empty the system before refilling it, he'd be in a similar situation I guess.

It certainly wouldn't be good if I got the normal section bled but not the ABS, went and engaged ABS, and had the brakes go away from air in the ABS system getting into the lines. I don't know if that's what would happen though.

When changing brake pads this weekend, I like to really clean the calipers. In doing so, I accidentally pushed out one of the pistons...and leaked a boatload of fluid out. It took a while, but I bled them enough so that there was no air and the brake handle was good. I will also tie down the brake overnight to get out air, and since I have the GS911, why not? However, I have no fear of my brakes working just fine as is....
