im having problems with both my fronts dragging. i replaced the two front brake lines a while back with the pads so im guessing the things just stuck. hopefully not a prop valve. no telling how much that will cost. abs light has been coming and going for about a month. got the wheels off earlier. pads look new still. i was shocked. rotors turn easily. figured maybe it was electronic so i just pulled the cables for a few hours. i did use my power bleeder when i changed the fluid a while back. i did not bleed at the master or prop valve just went straight to the calipers. we'll see how it goes this week. if the light comes on again i might just go to a shop. dont have much time
I recently cured my brake issues and gained 2 mpg city.
There are a number of causes for brake dragging. Flexible brake line internal deterioration, bad caliper, or in my case, the PO did not "fit" the pads and they bound. The cure for this is preventative action at install. The metal stamping of the brake pad has "fingers" that ride in a grove. I have been finding that I need to file to get no resistance as the stamping tolerances suck. A slight amount of slop is IMHO optimal.
