My truck has a slow leak in the brakes somewhere but I'm not really sure where. The brake pedal will go to the floor sometimes but it come back after I pump it a couple of times. My thought is a leaky brake master cylinder but there isn't an obvious leak on the outside of it. So I'm thinking the seals are bad and fluid is just seeping past it and making me lose pressure. Am I on the right track here or should I be looking somewhere else? I think my front brake lines may be a little suspect too.

check the inside of your tires for fluid runs , put card board under car for the night see what drips under motor

if you're not losing fluid from the reservoir, it's just sneaking past the seals internally.

I am losing fluid from the reservoir, just slowly and I don't see an obvious leak.
