Seems like I can never catch a break... After finding out I need new injectors and fixing the FICM myself I found out I needed new batteries. Now my rear brake caliper is busted and my ABS and speed sensor in the rear is out. I guess I'm lucky that I have the ability to do the work myself, especially after a shop telling me they would do it for $700! But before I start the work is there anything I need to be cautious of when putting on a new caliper and pads along with the sensor? Any tips/hints would be appreciated.
