Brake issue!
Symptoms:
My car goes from the "Max" to the "Min" on my brake fluid reservoir about every week. No leaks under the car overnight.
Scraping sound as I drive until about 60 mph.
Pulls to the left when you hit brakes.
Incredible amount of break dust on my wheels. I need a carwash daily.
Sometimes a small screech or squeal when braking. Not often.
Things I've done to attempt to solve this myself:
Jack up the front of the car. The wheels spin freely.
Search.
Problem:
???

A couple of things to check out. If your fluid level is dropping that quickly there is either a leak somewhere or your pads are wearing very rapidly, possibly due to a stuck caliper or faulty proportioning valve.
Look carefully for a leak at each caliper and along all the lines feeding the calipers. If there is definitely no evidence of a leak there, the master cylinder may be leaking into the brake booster--that big black thing the master cylinder is bolted to. To verify, remove the master cylinder bolts and have a look inside the booster.
Then check the brake pads to see if any of them are badly worn. [As the pads wear, the fluid will drop.] If there is differential wear of the pads, you may have a sticking caliper or a faulty proportioning valve.

There are no leaks on any of the lines, front or rear. I checked very thoroughly. The brake pads have just as much meat on them as when I put them on 3,000 ago so I don't believe it can be rapid wear.
When I removed the brake master what exactly am I looking for inside the brake booster?

Restricted brakes lines or hoses...
malfunctioning caliper assembly...
or loose brake calipers...
Master cylinder pistons not returning correctly...
maybe even a incorrect parking brake for the draggin sound

The rubbing noise was caused by the brake pad shims breaking free from the pads and rubbing against the hub!! Crazy that I didn't notice it until taking my wheels off. It wasn't break pad dust, it was my brake pads making a 1/16th of an inch incision into my hub!!
Scraping and brake dust issue solved.
Still the pull, squeal, and usage of fluid.
