I just installed a complete set of Galfer braided stailnless stell brake lines on my 09 Busa. I have installed these lines several times on other bikes. This time I used a small vacuum pump. I connectde it to the bleeder line, applied vacuum while pumping the brake lever. What a difference, the brake bleeding was done in 15 min per line rather than hours of trying to purge the air out of the lines. Highly recommended!!!
