Hey is there a tip or trick to bleeding the front brakes on our 250R's?????
I burned through a quart of fluid trying to get a solid lever but it still feels spongy.
Is it common to get air trapped somewhere in the line? Is there a special technique
I need to know about to get the air out?

Thanks!!

i use the reverse method


i use a bottle of brake fluid with a tapered nipple and clear fuel line attached.

attach the hose to the bleeder thats farthest from the master cylinder and hold the container of fuild up side down and break the bleeder. while squeezing the container, break the banjo. when no air is present close the banjo. repeat on opposing brake cylinder. once both are done then bleed the banjo by pumping up the lever and re-bleeding it.

its possible your master cylinder needs a rebuild too.
Well it had a nice solid lever before I took it apart so Im think an air bubble somewhere its not wanted...Heck when I had this issue w/ the Recon I thought damn its gotta be the master cylinder, so I rebuilt it...nope, just air wheres its not wanted.

So I feel like I should post because I did this yesterday. First I used the reverse method. Basically you make an IV for your brakes. This method did not work for me. It was leaking like shit, I mean where the iv I made outta a coke botte. Anyways, then I did the normal method. Keep your resivor full, I just pull lever and when your pulling the lever the nipple on your caliper should be turned to open, before the lever starts returning make sure the nipple is closed. It took no time at all to do this. If you took it all apart, then you should propably do the reverse method. They doo make guns for like 30 if you go to a autostore. Easiest way.

what sort of nipple did ya use to fasten to the coke bottle? a home made one or one as i mentioned? regardless.......... the threads on a pop bottle are different than any other. for future reference another alternative is to use a "huge" livestock syringe from the co-op that will hold about 65cc or ml.
