rear brake help

alright well i have a 2002 blaster with a hydro setup. They bleed out but as soon as i bleed them they dont work. the rubber gromet on my master cylinder is cracked in a couple places. could it be loosin pressure from there and thats why its not working?

that rubber "gromet" you see cracked is just a dust cover, it doesnt hold pressure or fluid, there are o-rings up inside on the piston that do all that work, and my guess is if they go bad it would leak fluid out the bottom of the master, pull that dust cover down and see if theres fluid in there, or would it be coming out of the cracks??,
and there is prolly still air in the system somewhere, are you bleeding them with the rezzie cap off, that seems to work better for me, be sure not to run it dry...keep it full
try gravity bleeding it, crack the bleeders and just let it ooze out, also try holding the caliper higher than the master so any air trapped in the line will rise up and out, also try holding it below for a few bleeds,
bleeding brakes sucks, gonna get me a vacuum bleeder soon, you may wanna try that too

dont spend you money.......get a spray bottle, take the cap(sprayer part is attached to cap) take the little straw off, replacve it with a rubber hose, place the hose on the bleeder and start squeezing.......it works the same was, it makes vaccum
