Replaced brake pads on a Patriot. I believe they were original. The design for the rear brake calipers is counter intuitive. You cannot remove the upper bolt/ slide because the flex brake fluid supply hose connection is in the way. If you do loosen it you cannot remove the bolt. Only the open end wrench could fit in the bolt due to the hose fitting. So, you could only remove the lower. Flip it up and slide the entire caliper off. Not much slack or room But, it does come out.
Second issue was the front brake hose have a hold down tab that crimps the hose. This became a blockage, so the brakes would ride on that caliper wearing and overheating..
