Last month I have been hearing a slight squeaking sound coming from my front right wheel on my 75 bay. It has been getting worse, intermittent but always seems to stop when I apply the brakes. Other times the front brakes squealed like anything, it was so loud. So I made the assumption that I may need new front disk brake components or that my bearings may be screwed as well. As such I was doing a bit of research on parts needed online and thought I should have a look underneath the car to get familiar. This is what I found: Left caliper Right caliper The retaining pins have come out of both sides, leaving one part of the disc brake pads unsupported on each side. I was pretty quick to fix the issue and place the pins back where they belong and I no longer have the squeaking or squealing sounds when driving about. So I am pretty unfamiliar with disc breaks, is this a common issue? Is it a warning to a much bigger issue on the whole?
