1. step
unscrew left caliper, hang it up so far
that the fender crossing hose leads only upwards
then bleed again at the left cal.
2. step
did u test if one disc is bent?
if yes , it pushes the pads every turn back into the cal. and you grab into the empty at the lever.
generally
using the zip tie trick to bleed the last tiny bubble only! works ,
when both hoses lead from pump down to the calipers.
if still a fender crossing hose is mounted the trick never will help "bleeding" the system finally.
my recommendation would be if not done yet - change to two looooooooong steel braided hoses
how?
measure the length of the RH
then order two lines
one in the length you took from the original at rh
the other 3/4" (20 centimeters) longer than the RH
watch the angles of the banjos !
(my hint : 20 and 0 degrees - the straight ones screw at the pump with a double banjo bolt and 3 (three) alu-washers)
