Bleeding brake problem.
Got an extended front line from 'Parts Giant', fitted it along with 'Speedbleeder' and could not get pressure on the line at all. Used a whole bottle of dot.5 fluid through the system before giving up. Had the caliper off to make sure the problem was not there, bled the connection at the master cylinder/reservoir and checked the caliper entry. Put my old line back on and using another new bottle of fluid got the pressure up to normal. I suspect the new line was to blame but what say you guys ? Have contacted the seller for either a refund or a new line...b.

Did you continue to use the Speedbleeder after you changed back to the older brake line? My luck with Speedbleeders has been problematic at best and they end up in the trash...

or
The line is not sealing and you're sucking air - could be a pin hole..., bad connection..., not sealing when tightened at one end or the other
or
You're not bleeding properly
When installing new hoses - reverse bleed - there lot of air to remove..., and air predisposed to travel uphill

Yep still using the Speedbleeder on the original line. I tend to think the problem is the new line not sealing, whether it's a pinhole just enough to let air in and not let the fluid out or the connections not properly sealing. Fluid is coming out of the bleed screw along with the tiny air bubbles, they just won't stop ! Pretty sure i'm doing it properly as I have brake pressure on the original set up. Never had a problem with Speedbleeders before and never had to 'reverse' bleed...b.

I usually reverse bleed with one of those hand pump oil cans. Cut the nipple off the end, and it fits right over the bleed screw. Get them at Harbor Freight for like $3.00 . Never had a problem doing it this way. Was necessary on my old Suzuki Intruder for bleeding the clutch.
I could never get it bleeding top to bottom, but never had and issue pumping from the bleeder up to the reservoir.

Seems like a lot of people have the banjo bolt hole misaligned with the passage which restricts fluid flow.
