No front brake!

I stupidly stored my bike with a bungee cord wrapped around my front brake lever applying the front brake. The front brake no longer responds to moving the brake lever. Little resistance at all. I would normally just figure this out but I'm going riding tomorrow on a last second offer from an old buddy. I've got much to do tonight... I imagine the fluid bypassed the cups in the master or maybe the caliper O rings aren't aren't retracting the pistons. Just wonder if somebody knows off the top of their head what's wrong and what I need to do? Thanks in advance.

Id give it a back bleeding by slowly compressing the caliper with my knee while holding the wheel with both hands. Then try pumping it up.

Thanks for the suggestion. I'll try it in the a.m. It seems like the master cylinder has plunged one direction (toward the caliper) but never returned back to its original position due to fluid leaking past the cups. Too tired to deal with it tonight...

If you cant fix it just remove the lever and pads be rear brake only, dangerous as hell but you can still ride!

You can remove the brake piston in the master cylinder, pretty easy as it's only held by a circlip - give it a clean and reinstall.

Empty the fluid out from the M/C, fill with fresh fluid, attach a syringe to the caliper and suck until you get clean all.

Pump up the lever and you should have pressure.

If it's still mushy, fill the syringe with brake fluid, take some fluid out of the master cylinder and back bleed.

Old3, you were right. I thought about what you said and thought that you were sorta reversing what went wrong, so I took a c-clamp,( rather than my knee) and used it to push the pistons back into my caliper. This pumped fluid back up to the master, pushing the master cups back to where they're supposed to be at rest .Of course, I was careful not to overflow the master... Voila! Took about 5 minutes. Thanks for your advice.

I may or may not have done this before. Downhills become very interesting.

Your very welcome! I do it pre ride or after my sight lap if I forget. Good thing to do when you unload. Keeps the air up and out, better braking is a good thing!
