I lost my power steering and brakes. I left it set for a couple days started it up and let it run for about a half hour and got them back, but had a loud noise coming from the pump when I turned our hit the brakes. I had read in a couple places to change the fluid, started to do this and noticed the fluid was all foamy. I changed the fluid and it took for ever to get power steering and brakes. Drove it this morning and lost it again, went to check fluid and seen it was coming out the fill cap, opened it up and it was all foamy again. What do I need to do?
