Well I got my brake pins today. I noticed a few things. First the threads are too long.
Secondly,the caliper moves so much I feel like it could slide off.

Thirdly, when I push the caliper all the way in it takes about three pumps of the brake to get the pads to the rotor.
Then they don't go back just as before

You do understand that the pads don't retract off of the rotor right?
They stay against the rotor, dragging slightly. They just shouldn't stop the wheel from turning when off the lever.

Are you kidding? That slight dragging they do drives me insane when pushing the thing around!

Time for some fresh brake fluid. If seated all the way to the other side, the pins are fine just like that.

I'm just trying to make sure you understand the pads will always be in contact with the rotor. There isn't supposed to be any space between them.

I guess there never really was a problem here. They never stopped the wheel from spinning. They just rubbed against the rotor causing an oh so annoying sound

I notice the same thing and it annoys me too. They're not like drum brakes that have springs to pull the shoes off the drum.

It especially bugs me because I come from cycling where you specifically adjust rim brakes so that they never rub

Make sure to get a new piston seal, it is what has the elasticity to pull the piston back ever so slightly. For the reinstall be cautious not to tear it, it holds all the pressure too! :partyman:

I don't get it. You tell me I don't have an issue but I keep getting solutions for the issue I no longer have

Everyone has been saying they don't retract by spring, when in actuality the seal on the piston pulls back after you release the pedal/handle by the elasticity of the seal itself acting as the "spring"...otherwise the pads would wear at an alarming rate and your fuel economy would be poor... Just a friendly lesson from a mechanic, I didn't realize there was a second page.
The noise you hear when pushing it around or at low speeds is an unfortunate byproduct of the design/pad material. However if it is dragging making the bike slow on its own and hard to push, sticky pins is the first culprit, cleaning the dirt from inside the pin tubes and off the rubber etc as it can push onto the pins. If after all of that the bike is still a slug piston is the next order of business, the seal being the most important and cleanliness of the bore/piston next
