Hi, has anyone had an issue a brake lever somehow not taking new brake fluid during a bleed process?
i have these on my Bianchi Oltre and having not touched the brakes in two years from new decided the front was getting a bit loose so thought i do a bleed to tighten it up. im a reasonably competent home mechanic, however for the life of me i could not get the new fluid to flow up from the calpier into the lever.
to cut a long story of wasted mineral oil, much swearing and time waste short i put the bike in the LBS however they have the same issue. they have been able to show fluid flowing from the brake caliper up the pipe/cable at to the lever so there is no blockage in the frame. it seems to get stuck entering the lever ? this is the firstime the brake on the bike have been touched. (2019 model xr 4)
the brake worked fine before albeit was getting soft ish. Im trying to get a warranty replacement from the dealer i originally bought from and so far they have been helpful although they want the entire system returned to them which is pain in the a**.
has anyonwe had this typo of block at the lever? is there some I or the #LBS are not doing? (they have been great btw)

Both yourself and the lbs tried to flow oil from the caliper to lever. Did you try from the lever to caliper?
Disconnect the line from the lever - does the oil flow from the bleed cup out through the now disconnected lever?0 -
