At least every two weeks I need to add a pint of brake fluid to my 09 Malibu. I have inspected and found no visible leaks. I have no puddles in the drive when I should since the fluid doesn't evaporate. I have not taken it to the dealer. I do most my own maintenance so I hope to fix this myself. Any other things that could be swallowing my fluid? I am open to any suggestions.
I had the same problem and finally figured out it was my right rear caliper was defective. I would lose breakfluid at a higher pace on the highway due to the force.
The caliper was under warrenty, but because of the problem both rear roaters needed to be "turned" and I needed rear pads too because the right side was working harder.
I've been doing my own breaks for 20 years so I know they were not trying to take advantage. Still will cost me $300
You may want to put news paper underneath the car and keep forcefully pumping the breaks to figure out where, but also look inside your tires rims
