So doing routine maintenance on all my bikes, decided to tackle brakes on all of them. A GS650GL (Back and front), an XS650 front (drums in back) and YS250 front. I also had the brilliant idea to replace the lines for SS lines.
So the XS went under the wrench first, less than 2mm of lining left. Bled the system of all fluid. Removed the caliper and lines (two piece became one line direct from MC to caliper). Cleaned all pertinent parts, and reassembled. Then the pain. filled the MC with DOT3, and started pumping. Nothing. After about 2 hours of pumping, and the fluid slowly draining into the system, I got to the point where no more fluid would flow, but, there was no pressure. I knew there was air in the system, but I could not get it out. So I started taping the line. Bubbles started to come up, slowly. After another 4 hours, finally some pressure started to build and I could start the bleeding process. All in all, I figure it took me about 8 hours, full at it, getting the air out. Tapping, here, tapping there, etc, etc. I realized I needed some kind of mechanical interference to drive the bubbles up. That was last weekend. MY LORD what a difference New EBC pads, SS line and fresh fluid made.
Today I decided to go at the GS. Since I want to ride it these Sunday. This bike has two MC's to tackle. Not wanting to spend 16 hours, give or take, I wanted to come up with something new. Something to SHAKE the bubbles out, something to vibrate them out. VIBRATE?? I went to the drugstore and (don't laugh
) looked for a lady's best friend. I found some minidoojobbers, that you put on a male partner to please the female one 
. bought two of them for 5 bucks a pair. Went home, taped them to the brake line. Turned them on. Started pumping the MC and bubbles FIZZLED out, literally. Got my brakes, dismantled, cleaned, new parts installed and bled in about 1 and a half hours.
So if and when you name your bike, give it a ladies name. Big Berta sure liked them midfrequency gadgets....
