ok, so my front brake felt really shitty and had little stopping power. i checked the fluid, and sure enough there wasnt a drop in there. so i bought some dot 4 fluid, and ATTEMPTED to 'bleed' the system. upon starting this, i cant get it to work for shit. i can pull the brake lever all the way to the peg, with ease. how do you properly bleed it so the brakes regain pressure? i need help bad!
