hel brake lines, pics and advice?

Suggest you may have more success filling the resevior and using the syringe to suck fluid through from the top.

Pulling the lever back shuts off the path through the master cylinder rather than opening it, so don't do that.

ok progress so far.....

after the pipe coming off the syring and spraying me and he garage floor in brake fluid,told you im not the brightest hehe

iv taken the cable tie off the brake and i have fluid IN the master cylinder but only a little bit at the mo so ive stopped.

if i do the same on the other side till the bubbles dissappear i should know the both lines are full of fluid yes?

and then just top up master cylinder....hopefully anyway

maff

btw the bike is stripped to beyond naked as im cleaning it this week ready for the winter, might be the only chance i get, so not much for brake fluid to get on to

Are you filling from the bottom? If so you'll struggle to know when all the bubbles are out - they may be on one side but not the other. The reservior will have filled to the brim before that, so you'll have to drain some of it.

yes filling from the bottom

maff

Ok. Think you'll have to just do up the bleed nipples periodically, and squeeze the brake lever. If it's spongey, you've still got air in it.

ok, both lines are full, master cylinder is full and the top is screwed back on but i have no brakes! you can pull the lever in all the way to the bar and nothing happens...any ideas?

maff

You've still got air in the lines.

I'd suck fluid out from the calipers if I were you. Remember to top up the reservior as you go - if you don't you can let more air in at the top and you'll have to start again.

ok slap me, i'll be your bitch

so why does air come out of the system when you cabletie your brake lever overnight?

iv tried sucking it out from the bottom and as much brake fluid is coming out im getting the same amount of air bubbles. either im opening the nipple to far or iv knackered something

the brake lever feels better but not what i know it can be so ive given up for now. ive zip tied the brake lever to see if that will do anything over night if not then im stumped

maff
