I just tried changing front brake pads on my wife's 2008 impreza sport. She told me last week that she was getting a brake light coming on the dash.
I have never done brakes on a subaru, but have done many on Chrysler, ford, honda, etc.
For some reason the passenger side is binding up with the new pads? I had purchased new rotors as well, but didn't bother to use them. The old ones don't look that bad. I even tried a new rotors on that side as well, but it didn't make a difference. She only has 50,000 kms on the car.
I ended up putting the old pads back on for now.
The other thing I noticed is the pad kit came with only one pad with the wear tab, the other three are identical. The pad kit came with a piece of paper saying that the wear tab goes on the passenger side only (right side)?
Anyone have an ideas what could be wrong? The other side feels great.
