Milky brake fluid?

[kyle1911]

it seems to have a very milkly look to the fluid when it comes out of my caliper when i bleed it. occasionally there will be air bubbles that bubble up when i pump my brakes in the resvior. what is the cause of this ? i also have an extremely spongy brake petal though i can lock up the rear the front has no stopping power.. i will continue to bleed it but i want to see if there are deeper problems :help

any ideas i fear for the master cylinder but would liek to avoid this route if possable.

*i have new rotors and pads installed all around and i greased up all the sliders which were sciezed*

Thanks

how old is the fluid? my guess would be water contamination or frothing.

bleed the whole system. also make sure not to pump the pedal too rapidly because that can cause the frothing i mentioned.

its most likely frothing because water contamination will usually cause the fluid to be black from the internal corrosion it causing.
