Front brake hydraulics gone

Ok, second ques while Im on here.
Lost my front brake while riding, cable came loose and either lost fluid or got air in it. Any help on how best to bleed the system and refill? Not sure where I would actually bleed from.
Thanks

There is a bleeding screw on the front caliper. Sometimes takes a bit to get the air out.

Your brake line "came loose" while riding???????????

Holy shit. New bike? Bought from Yamaha?


An old school "trick" for bleeding air from brake lines is to strap the brake lever against grip, or as close to it as you can pull it, and leave it overnight.
Use rope or something to tie the lever against grip.
