brake system
yes, the valve was fully open.
what about this theory : when i release the pedal for whatever reason the resistence to suck in fluid from the reservoir is too high. an underpressure is build up and air is sucked in thru the rear rubber seal that is close to the brake booster.
these seals are conical so they are great to seal overpressure but maybe fail if an underpressure exists in the piston area of the MC.
the air gets into the piston chamber and because it is air and light immediately exists to the reservoir room.
but still that doesnt explain why the braking power is low, because when bleeding the MC there is no air coming out of the hose.
