zip tie the lever to the bar all the way in...and take your resivoir cap off make sure its upright
leave it like that for an hour or two or overnight..it will push all the air bubles out through the resivoir
then put the resivoir cap back on and cut the zip tie. it will be tight then

Re: problem bleeding brembo handbrake with 4 piston
when i bled mine, i did it off the bike....the way the calipers mounts it traps a bubble right in the caliper
i used a motion pro tire spoon to keep the pads seperated(as if it were a rotor)
try that if u havent yet

Re: problem bleeding brembo handbrake with 4 piston
i think (THINK!)what it does is dissolve the air into the fluid. air does that under pressure..

Re: problem bleeding brembo handbrake with 4 piston
the zip tie method is a good idea i do that after the initail bleed and it seems to help.
i also use a handheld automotive vacuum pump at the bleeder valve to assit me with the bleed. and i tap the master, line and caliper with a screwdirver, socket wrench, or metal object buring and in btween bleeding. i bleed and bleed..... ride a bit and bleed again.
i run a hohey 4 piston set up, but remember your handbrake is only as good as you bleed it.
check out this thread too. it has some good info.

Re: problem bleeding brembo handbrake with 4 piston
how does it do that then?? if you push the lever to the bar, the master cilinder is sealed! if you squeezed the brakes, but air(pressure,fluid, etc) could still make its way from the brakeline to the reservoir, how could you ever accumulate brake pressure?
i think (THINK!)what it does is dissolve the air into the fluid. air does that under pressure..

Re: problem bleeding brembo handbrake with 4 piston
yeah your right, sorry bro....... it doesnt answer the questions. and i dont have the answers either.
just figured i'd post it up in case it would help or if anyone wanted to check it out since it is about the zip tie bleeding.

+1 on the bleed and ride and bleed thing. air tends to get trapped in the foot brake master. If you hear a whistling noise (at the footbrake master) when you sqeeze the HB than i would tap on it or take it off and tilt it while your bleeding it. I use the FT adaptor as well w/a 4 piston caliper.

i think (i'm jus spitballin) the idea is not to build hydrolic pressure but to keep any airbubbles from forming in the brake master. if you had to rule out the possiblity of the master having a leak this would be one way of finding out. but maybe he forgot to mention that you have to crack the bleeder valve and tighten up right after then zip tieing the lever. but once you cut the zip tie you would still have to pump the brake to build presure afterwards and hopfully air won't be drawn from a leak somewhere.
