Get #2, it's got a cup and a road lever adapter, half your bleed issues can be solved by just putting the cup with some fluid on the lever and pumping the lever repeatedly to burp bubbles out, tap the hoses a bit at the same time. If you actually need to bleed it then I usually syringe the fluid into the caliper, through the system and then into the cup, then lever a bit back through and push that again, close caliper bleed port and do a bit of burping, usually works first time and takes 10 mins max. If it doesn't work then sometimes there are bubbles behind the pistons so allow the pistons out a bit with a thinner temporary bleed block, try above again, spread pistons and should all be good.
Ordered. I don't know what fluid is currently within the system, thus is it better to drain it completely and refill? Or are the fluids compatible and I just need to top up what's already there and get rid of the air?
