shimano 785 bleed diaster help meant to be riding tomorrow AM

Trying to bleed my 785 rear brake before a ride tomorrow morning. I’ve got the epic bleed solutions 2012+ kit. No matter ehat I do im unable to syringe any fluid into thr bleed valve of the caliper! Ive got the funnel/empty syringe connected to the lever reservoir but no fluid ever enters it!

I’ve taken caliper off frame and its below lever still cant get fluid in.

Any ideas?

At this rate im out of tomorrow’s ride as my rear brake is now unusable.

So fed up been trying hours now.

Is it some kind of air lock?

Thanks

Have you tried an elastic band round the brake lever to handlebars?

Try opening the bleed valve more than the 1/8 turn they suggest?

Have you taken plunger right out of top syringe ?

Not sure on how the Shimano calipers work – have you opened the bleed valve?

Tried rubber band same issue.
Ive tried opening bleed nipple valve on caliper more same issue.
I’ve taken plunger out of top syringe completely

Have you tried undoing the freestroke screw 4 or 5 turns ?

don’t use the syringe,
under bleed nipple, pull lever in, close bleed nipple, release lever (lever should keep full due to yellow funnel in there.
and repeat, (its the old fashion way and it still works!)
Also have to taken the pads out and put in the block to bleed?

Put pressure in the system by squeezing the lever. keep opening the bleed nipple.. something has to spurt eventually!

Yeah, but he’s doing it bottom up like in the epic instructions surely

yeah you need to undo the free stroke screw a few turns

freestroke info. My experience anyway 🙂

Yep its the bastarding freestroke screw. Fluids going in fine now! Bastard thing!

Thank you very much all lifesavers.

Owe you all a pint

Bit late to this one. The free stroke adjuster strikes again! Glad you got it sorted. 🙂
