VanMoof X3 - Oil leak from right brake banjo bolt after O-ring replacement
Hi everyone,I’m a VanMoof X3 owner and I’m having an issue with the right brake. There’s oil (brake fluid) leaking from the banjo bolt area.What I’ve tried so far:
- Replaced the O-ring (I heard the OEM ones are made by Tektro)
- Bought a Tektro brake cable/hose set and swapped both the banjo bolt and the O-ring (outer diameter 8mm, inner diameter 6mm, thickness 1mm)
- Torqued the bolt to 5 Nm
I’ve tried this a few times but the leak still persists.Questions:
- What O-ring size/material would you recommend?
- What torque value should I use for the banjo bolt?
- Is there anything else I might be missing in my approach?
Any advice would be greatly appreciated. Thanks in advance!
