Trying to get the rubber internal seal on end of syringe ram not to slip off is a drag once brake fluid swels them. Better design is the o-ring type but haven't seen a big one.
I just bought that Repco one as i got a chrissy voucher that got me partway there so figured buy something you wouldnt normally.
Actually it works but its not magic. For empty system it was a whole lot quicker and that was the main desire. Yes it pulls bubbles from the threads, maybe if I only cracked it a bit . . .
You still need to pump lever a little at the end to move the pistons close and last air out whilst manipulating the nipple open and closed. Whether the suction aids to a better bleed I can't say but would be worth it for difficult setups.
Much of the tube I seem to find locally slips off the nipple (some of this stuff is just odd to write) so I've cable tied it. The stuff in the Repco kit seems to fit well so far.
Longer nipples would help. But a mate gave me some tube capiters (I don't want to look up the right spelling in case I get emotionally scared) but the fitting with a slight trim holds fast onto nipples. Vicar.
So yes I'd mildly recommend the Repco system. Its not rubbish and it is useable. But its not a panacea to traditional lever manipulation.
I've been told. Dreaming`s free.
Think I'll go, back to sleep.
