I will be changing the rear pads on my daughter Accord 2000 this weekend. I'm familar with changing pads, but I not familiar with the a piston that must be screwed in, rather that pushed in, to make room for the new pads. I'm tryng to understand the concept of how this works.
As the pads wear down, does the piston screw out to take up the slack? On the front brakes, the piston just protudes further to take up the slack and the fluid level falls.
Let me try to state the question a different way. If you screw the pistion back into the caliper to make room for the new, thicker pads, does the piston screw out to take up the slack as the pads wear down? How does this happen?
