I've got a 2001 Outback 2.5L with 186,000 miles. About a year ago I replaced the front passenger side brake caliper after it froze up. A couple weeks ago the same caliper froze up while I was on the freeway. I drove a few miles to an exit with the steering wheel vibrating hard and towed it home. After replacing the caliper again I get a heavy grinding that is consistent with the rotation of the wheel. It sound like grinding brakes but real loud.
Here are the steps I have taken before getting stuck:
-checked brake lines, all look good
-checked brake fluid, bled out all air, it looks clean and fine
-installed new caliper
-new brake pads on front brakes (old pads on passenger side had worn at a slight angle not parallel to back of pad)
-had the rotor turned at local auto parts store
I'm definately no mechanic but try DIY as much as possible. I was thinking it could be a bearing or bad axle but not sure. Any help on troubleshooting and how to fix would really be appreciated. I cant really afford to pay a mechanic
