I have a 2007 Mazda 3 (2.0L). Recently, I took apart the front axle in order to replace the half-shaft on the driver's side. At the same time, I have replaced my brake caliper because I realized (coincidentally) that the caliper piston was stuck on that side, causing the brake pad to be constantly in contact with the rotor. Of course, this created a large amount of heat, and I've noticed that my ABS speed sensor harness is a little melted now (presumably from the heat) - see image below.
I have five questions about this:
1) Since my ABS light isn't on on my dash, can I safely assume that it's fine as-is, or is this something that will likely come back to bite me later on? 2) Is there a way to test my anti-lock brakes? It's summertime here, so I can't just go out to a parking lot and slam on my brakes to see if they engage, as I would in the winter when there is ice around. 3) Since the housing is melted around the screw, how can I remove it if I wanted to replace the sensor? 4) How difficult is it to replace? (It looks like I have to take off a few other components to get at the cable as it runs up underneath the vehicle... Can I just cut the wires and re-connect new ones to a new harness with heat-shrink tubing?) 5) It is possible that the inner housing of the sensor is also melted (the socket into which the harness mounts). If so, how do I replace this?
