5. I found that the brake caliper mount was installed upside down. Would it matter? I'm not sure, but I will be reinstalling it properly. The first photo shows how the pieces should go with the 5⁄16-inch bolt holding the two brackets down, which in turn supports the caliper. The second photo shows the parts upside down, improperly mounted. If you didn't know, I guess you could figure they could go either way. Some people wouldn't give it a thought.
