Yes, bleed block in place:
1. Remove wheel + pads. Add Yellow bleed block
2. Level lever, pop lever port screw and apply funnel with 2cm of fluid into lever port
3. Prepared syringe with genuine Shimano Mineral oil (lubed plunger with mineral oil) attached to calliper bleed port (just above 7mm spanner).
4. Plunger removed from Funnel, open calliper port (spanner) push on syringe to feed to funnel.
No fluid moves up, or with the mother of all effort it does in a non smooth hand hurting way.
5. Working in reverse, nothing drips out from the line when letting the funnel bleed to the calliper.
However if i squeeze the lever the fluid will come out at the calliper end.
Managed to pull back on the syringe to draw air through from the line (whilst the funnel is attached and filled with oil). This was again very hard to do but it did pull out some air.
so yeah, all the suggestions and silly things to miss along the way are covered (i think). I’ve tried it with the servo wave and lever adjust at different settings, still no joy.
Still need help!!!
