Bleeding air from front brake

I think I have some air trapped in the Brake line splitter. Any tips on how to get it out?
I've pumped plenty of Brake fluid through the system with the brake lever, I have T tape on the bleeder screw threads to keep them sealed and a clear tube from there to a jar. The bike is on the center stand and i don't get any more bubbles when bleeding but still have a mushy lever.

you need a bleed kit from harbor freight....$4.99 www.harborfreight.com/one-man-brake-bleeder-kit-37201.html

take top off of reservoir. fill it up to line. pump break lever a few times and hold it in. open the bleeder, you will see fluid come out into clear hose....close bleeder and release handle.....repeat this process several time till lever becomes firm.

if during this process the system dosent improve.....you may be leaking somewhere? have damaged parts or a bad diaphram.

A tube into a can or bottle will work.....but the tube will keep fluid off painted surfaces and things clean and keep air from entering at the bleeder.

Roadflyer,
I have had a great deal of success "reverse bleeding" my bikes. Start with a 20ml syringe, some clear hose and some fresh brake fluid.
1). suck all the fluid from the master cylinder.
2). open the bleed nipple.
3). attach a length of clear hose to the syringe.
4). fill syringe with fresh brake fluid.
5). attach syringe hose to bleed nipple.
6). slowly inject fluid into bleed nipple.
7). when fluid appears in m/c use caution not to over fill reservoir.
8). close bleed nipple.
9). repeat on other line if so equiped.
10). squeez brake lever a few times.
11). go riding!

This is a great way to bleed brakes. It actually forces the air bubbles in the direction that they WANT to go, rather than forcing them in the direction that is un natural to them. The bubbles WANT to rise, they just sometimes need some assistance. Good luck, Paul
Don't be ridiculous! It's only a flesh wound!

had the same prob but found that popping or snapping the brake handle lightly 2 or 3 dozen times cleared it up.
