I was setting up disc brakes wrong for years without knowing it

I had this moment last Tuesday while working on a customer's gravel bike. The rear brake kept rubbing no matter how many times I centered the caliper. I was about to blame a bent rotor when my buddy, who runs a shop in Boise, texted me a picture. He just pushes the pistons all the way back with a plastic tire lever before he even bolts the caliper on. I'd always just squeezed the lever a few times with the wheel out to move them forward. Turns out I was starting with the pistons already extended, fighting myself from step one. I tried his way on the next three bikes and each one lined up perfectly on the first try. It's a tiny thing but it shaved like 15 minutes off each brake job. How many other little tricks like this are out there that we just never get shown?

Sounds like you were making it way harder than it needed to be.

Actually, I don't see it that way at all. The simple way just didn't work for my situation. I had to try a few different steps to get it right. Sometimes the easy fix misses the real problem. What looks hard from the outside is just what the job needed.
