hey guys- i've got spongy brakes, and i think i've got some stubborn bubbles in there. i've been bleeding them the old fashioned way, and i've decided to try one of these hand pump bleeders. http://www.sears.com/sr/javasr/product.do?BV_UseBVCookie=Yes&pid=00947058000&cat=Mechanics+Tools&subcat=Automotive+Specialty+Tools&vertical=TOOL&ihtoken=1 have you guys had any success with these? do they just add complexity to an already annoying maintenance item? if this doesn't work, i think i may have something else wrong. might need to do some more detailed brake maintenance.
