You may not have flushed the power boost system that is the power steering fluid in the power steering unit. It has to be clear otherwise it sticks in the chamber causing the brake master cylinder to not return the fluid to it after braking. That eats up the brake pads and burns the rotors which causes the pulling as they develop hot spots that many time cannot be machined out. I flushed mine by using a fluid retractor like a turkey baster and then refilled it turned the steering and pushed the brake peddle down. You have to repeat this about 4 times to get the lines and chamber flushed and all the old burnt fluid out. Just be careful as it's toxic. Also check your brake fluid for color as it too can get burnt due to overheating. After this is done you will have better brakes and get better MPG's as the brakes aren't dragging on the rotors.
