Ok quick question. I have changed front pads in the past. My vehicle needs new pads front and back. Back does use pads and is not drums. Is the process to change back pads the same as front? I def want to do this myself to save money. It has been a while though. For those that have done this, do u recommend taking some brake fluid out of the reservoir before pushing the piston back in? I think I remember doing this so that the fluid does not overflow the reservoir. Any advice is always appreciated.
