Just bled a hope E4 brake with the proper Hope kit - the funnel and the hose that clips onto the bleed nipple. What an absolute, mess-free joy. No pads out, no fiddling, and apart from a quick wipe around the edge when replacing the diaphragm/lid, no spills.
Bonus tip also, courtesy of some random instagram chap, if you connect a syringe to the hose, you can push fluid from the bottom up, which clears a load of air really quickly, then bleed as normal after that,
Yeah, bottom up is the best way to bleed any system as long as it's not got some vulnerability (like, some car brakes can have seal issues if you pressurise them backwards). Air wants to go up
Have always reverse bled (from caliper up)...I've never understood why pushing air downwards is apparently better than using its natural bouyancy and help move it upwards.
Suspect someone who knows the science will explain it to me but I can work out the why.
Certainly pushing from reservoir flushes the crap in the caliper out quicker.
I think it's from car/motorbike brakes where you pump the pedal/lever to push fluid from the master cylinder down to the calipers.
The normal method always worked fine, to be fair, but the kit genuinely makes it a 5 minute job.
