I own a 2003 Kawasaki Mojave and have been unable to bleed the rear line. Fluid is being pumped from master cylinder, yet won’t flow through to the bleeder valve. It appears the hole in the hose inlet bolt is working and lined up properly , yet seems to be gummed up or simply not flowing through. Note: these are newer amazon replacements. Not oem.. it was also working fine until I replaced the pads and rotor .. any help would be great appreciated!!!
