Was there much air in the morning, just want to know if it is worth doing the overnight test? Nice technique, don't be like me and use a pharmacy syringe, the have too small an outlet for the hose and can spray back at you.
Thanks for the video. My bike's brake fluid flush is long overdue, and I am thinking on using this method, just the other way around, mean sucking all the old fluid from the reservoir, topping it with fresh fluid, and sucking it from the caliper using a syringe and a hose... your method seems fine, but I fear pushing air into the system, my bike has ABS and I hear that if any air bubble make it into the ABS pump, pushing them out can be a pain in the a*se... what you reckon?
If the system already has fluid in it, flushing it through from the top is easiest. This method is for when the system is completely dry after a full rebuild
i just use a syringe and fill everything up from the caliper. you have to be gentle or the tube will pop off but open everything top and bottom and syringe a load of fluid in there until you see it come out the top......this work for the fs450, for a road bike it might not work due to abs system etc
Thank you! Used this technique on my cbr900rr and worked a treat
If you don't put grease around the bleeder, it will catch air
I have problems with normal air bleeding on this 4 pistons brakes , because the master cilynder don’t make any pressure

and of course you close the brake reservoir so the fluid doesn't capture water from the air over night?
Even brembo 2pot it hard to do

Mine is completely empty because its a all new system so how do i get the fluid from the resovoir to the lines and caliper?

Hvyy bro 🙏🙏
Doesn't work, it's just doesn't go up at all.
check to see if you have a check valve (like a speed bleeder)in the line
