So hey, just a quick anecdote from me about having the right tool (and knowing what you’re doing).
On the minivan, the back brakes started getting squeaky, and so it was time to change the brake pads. I’d done similar jobs before, and I thought to myself, how hard can it be? So I pulled the wheel off, loosened up some nuts and tried to put it all back together with new pads. There was only one big problem, however, and that was, the piston simply would not budge!
I finally used internet university to find out what I was supposed to be doing. I found this very helpful: http://www.paulstravelpictures.com/Chrysler-Town-and-Country-Rear-Brake-Pads-Replacement-Guide/ and in there it says I need to wind back the piston using a special tool. I went to the local car parts shop, and they had one! But it didn’t fit. I went to a bunch more shops, and all they carried was the little thingy that didn’t fit. I finally went to Chrysler and asked them what they use. The mechanic showed me a very professional looking kit, and I thought wow that must be quite expensive. I looked it up on eBay and it wasn’t too bad. Probably overkill to get a special tool for one job, but I figured I’ll probably use it again on the other brakes, so why not.
With that tool, the job was literally done in less than an hour, piece of cake. Looks like this:
