Talk me through the two syringe method then?
Dud mine today with the little bucket thing on the lever (shimano)

Re:
I use one syringe connected to caliper with clear tube then top up lever, Hope Mini, between pumps. I can see the air rising up tube to syringe so when no more came out I though all the air was out. Clearly it wasn't.

Partly fill both large syringes with appropriate fluid and connect to both bleed nipples via adapters and plastic tubes.Make sure the pipe fittings are secure as they will be under pressure. An extra pair of hands helps. Ensure both syringes are held plunger up so any air vents away from the brake. Push almost all the fluid 2 and fro i.e. from syringe to syringe gently squeezing the brake lever from time to time. The excess air will be forced out of the system at either / both ends and accumulates in the syringes forming a bubble by the plunger. if needed hold one plunger still and then use the lever to force the other plunger to move. Remove bottom i.e. caliper end first.

Re:
That wouldn't work with the Hope Mini lever as there are no bleed nipples on lever. Any time I've tried to push the fluid through caliper to lever via bleed nipple using a syringe, just results in brake fluid pishing out the bleed nipple threads as they aren't sealed and the fluid under pressure leaks.

Sorry, never noticed that bit earlier, they're Hope Original M4s with Mini levers, 180F/160R discs. They might be old but they don't lack power.
I just need to be more thorough bleeding them.
Re:
I replaced the hose on my Reverb Seatpost the other day, and shortened the rear (Shimano) brake hose and bled it afterwards just to be sure.
Modern Shimano with the "cup" you screw into the lever is essentially the same method as Hope brakes (where you just fill the lever reservoir with fluid and pump the lever/open & close the bleed screw).
The Reverb was same as Avid brakes, a syringe at each end and you need to grow an extra hand
Patience is key, and be thorough, or you'll be doing it again! gets easier and quicker the more you do it though.
I always found Hope brakes to have great power and modulation, but personally prefer a more on/off feel that I can get with Shimano.
Today's job is to set up suspension front & rear, then go ride
