I have a 01 Busa and every spring after sitting all winder my front brake lever bottoms out and the front brakes dont work. After you bleed them they work fine all season... until this past year. This past spring i bled them and they wont stay bled now. There are no fluid leaks. I assume i have a leak large enough to suck air but too small to leak fluid. Before i gonand rebuild the front calipers and master cylinder i think im going to change the factory front brake line and put a new set of stainless lines on it. This should eliminate the lines and copper gaskets from the potentional source of the leak. Has anyone had a similar experience and what lines do you reccomend? Im currently planning on buying a Galfer set. Thanks!
