Title: Reverse bled linked brakes for first time any tips?
Post by: Gusable on June 18, 2026, 09:08:39 PM
So my bike doesn’t have the bleed port on the splitter. I started at front, didn’t get any fluid going ( apparently you have to open bleeders more than I thought) anyway started at rear, got fluid going, then did the front, then the rear again total of twice on each caliper I think. Clean fluid no bubbles. Didn’t take any time at all. Super easy. The threads did leak on me. I hear ya on the Teflon tape idea. Anyway the pedal went from “notchy” to very smooth and linear. They were grabby and bitey at the end of the pedal stroke now much smoother. What was it— leave pedal down overnight with cap off? Traditional pump and bleed a bit? I’m pretty sure I’m good..but wondering if I have some air somewhere. Front went ok.. lever wasn’t great before, now has some WHOA NELLY but it’s a the end of the stroke ( which it didn’t have before). Maybe speedbleeders next time?

Mark Etheridge at Moto Guzzi Classics just did a video on that issue…neat trick

Take the master cylinder off the frame, then tip it forward and pump the pedal. Then tip it rearward and do the same until bubbles come out

Repeat forward and back again…

The air gets trapped inside the smallest portions of the master cylinder. If you’re on the side of the bike looking at the MC, you want to rmove from the frame and rotate it clockwise and pump a few, then rotate all the way counter clockwise and pump. Repeating until you get a good shot of fluid lifting out of the MC with each stroke

After not having much luck with the traditional bleeding method I started using a mityvac which draws fluid through the caliper instead of using the pedal to push it through.
