OK, now for the run-down

You shouldn't need to resort to extreem suction to get the brake fluid moving downward. Maybe your master cylinder is gunked up on and blocking flow? The Suzuki masters have a tiny little feed hole, or air release hole, not sure which, that gets plugged easily. Not sure but your CB may be the same.

Steve,
splitfire is the the brand of the plug I pulled. I will have to do some reading on these, thanks.

Nessism,
I think you might be on to it. I primed the MC, so I know that is working. I have air coming out of the bleeder nipple when I pump just no fluid. I figured the vacuum would get the best results. If they were clogged, how would I clean them? Just spray brake cleaner into the cylinder?

Also can anyone take a picture of the small feed hole on the masters? I am not sure if the CB has one, but if I knew what to look for so I could clean it, that would be great!

I found the best way to get new lines started on mine was to put a length of rubber on the bleed nipple & suck hard!

Without doing that there was no way I could get any fluid down to the calipers.

salty_monk,
I sucked so hard I thought I was going to suck my face down into the tube. I think there is something else wrong. I sprayed the thing with a ton of brake cleaner. Maybe that will free up some sort of gunk or something.

One quick question. Did you prime the Master Cylinder before sucking? I haven't tried that yet maybe that's what I am doing wrong.

When I suck I can taste the Brake fluid, but the actual liquid doesn't move. The level in the master cylinder is exactly the same. Anyone have any suggestions? Am I missing something? I have read so many posts about this and tried everything, but I can't seem to get it going. Someone said something about cleaning the calipers. How would I do that? Again this is a CB650. But compared to me GS it looks very similar.

yea, i was going to ask... try priming the cylinder first

[KRISTI'SGS550]

I have the cylinder shooting out brake fluid when i push the lever with the bolts and banjo off. But as soon as I put them back on, all that comes out is air and I can feel the air coming out of the bleeder needle on the caliper. It's really confusing me.

push the piston out by compressed air, take the rubber seal out - see what's the condition - cleaning with the brake cleaner and lubing with the brake fluid should be enough (but if theres rust you may need to sand the cylinder - piston lightly with emery paper)

awesome psyguy,

I will try that now. I am sure you still wont be on here when I am done, but just in case. I will keep you posted.

thats good news
so, its either the hoses or the caliper
your hoses may be clogged inside (including from falling to pieces due to age). try compressed air.

[KRISTI'SGS550]

psyguy,
my hoses are brand new. Should I still blow some air through them? Maybe they need primed somehow because they are new?

[KRISTI'SGS550]

What about the bolts on these things? I mean what if the hole doesn't match up with the hole in the banjo. Will the fluid still flow? Or will it be like my situation and just be air?

that's good, one problem less. no "priming" needed for the hoses

absolutely, the holes have to match! you can inspect the alignment visually while the bolt and the banjo are apart
then,
take one thing at a time
the master is working...
so, fit the hose now and make sure you get the fluid coming out at the other end of the hose
then, onto the calipers

This right here it me problem. I bet the bolt and the banjo don't line up. They are new banjos but old bolts. I will have to find out where the hole in the bolt is when tight. Then position my banjo to that specific destination. I bet that's it. I wasn't lining them up earlier. I just put them on and tightened them wherever, paying no mind to their positioning.
