Hi there
i own a 2002 YZ426
i had to put a new front brake line on, so l decided a braided brake line
B4 l removed original line l didnt flush all the brake fluid out of master cylinder and caliper

So after putting new line on and trying to bleed the brakes. Nothing would flush through the system

i have pumped the brake lever so many times , and tried numerous ways to get the fluid through.

Seems as though the master cylinder has a BIG air bubble??
Fluid does dribble out but extremely slowly
i am using a one person brake bleeder line on the caliper also

Any suggestions that may help would you mind responding and give me the tips.
i have just done a top end rebuild(valves etc) and l cant even ride the bike.
