Brakes leaking
Have a leak somewhere and I need help finding it, I am losing 3-4 ozs of fluid everytime I drive.
I have narrowed it down to the line that comes out of the resevoir, anybody know where that goes?
I know it is in that line, as the fluid level never drops farther than that hole.

I don't see any fluid anywhere, also forgot to mention that the front left wheel pads are always tight against the rotor. Wheel will not spin freely.
Thanks

You could have a leak at the ABS pump. It's located in the compartment behind the driver's seat. There is a single screw that has to be removed to raise the lid. You will probably need a flashlight to check for any moisture at the bottom of the compartment. There will be hard lined going into the ABS unit and going out.
The hard lines from the master cylinder go to the ABS pump.
When you say the fluid level goes down to the hole in the reservoir, can you still see some amount of fluid covering the hole? If the fluid goes down so far that air is trapped in the hole when you refil the reservoir, that can cause air to be trapped and there will be a loss of braking effort.
For the caliper, it's possible that the piston is sticking in the bore, or that there has been some debris in the line that made its way to the caliper and is blocking a passage in the caliper.
I would start by doing a fluid flush by filling the reservoir with fresh fluid and bleeding the brakes until clear fluid comes out.

If you jack the car up and loosen the bolts for the master and the wheel is freed up, then that is a sure sign the rod has to be adjusted.
The pipe as Cruiser said is for the ABS. Its used as part of the ABS self test (ratchet noise) when you first drive the car at about 6 mph. There is a bleed on the ABS pump for that pipe. Check to see if it is leaking. It is not under pressure, it is free flowing from the master.

Sorry for the confusion, I meant it leaks down to the Prime hose outlet.
Not all the way down, I have checked the ABS and no sign of a leak.
I am going to replace the Prime hose coming out of the resevoir to the metal line, I have fuel line of that size.
Question is, can I use that or is there special hoses just for brakes?

Ok just so you know, the rubber hose for the ABS prime line has been discontinued and if you can find one, it is $80.02. 
And we wonder why GM is going under!!
SO, anybody know where you can buy rubber brake hoses????

Ok, got the leak fixed and bled the system. Now the brakes won't hold pressure.
Bled the system and brakes stayed perfect for about 4 hours and slowly lost pressure, I drive the car and the longer I drive the better the brakes get.
I drove running errands and after a half an hour the brakes were perfect and stayed that way for the rest of my drive, had lots of 5 minute stop and everytime I started the car the brakes were perfect.
Got home and a hour latter ran another errand and the brakes were a little spongy and then were perfect.
I know I have air somewhere, but I cannot figure out were, was wondering if maybe I got air in the ABS?
