This ensures the rotor is flush against the hub and decreases chance for warpage.
Yeah. It's like installing wheels on a car. Criss-cross pattern.
A t-25 is all you really need that you might not have already. Just follow the directions that come with the disc brake, they are usually pretty good
I already have torx tool for it. These are not brand new discs however. They are slightly used. Came off of a new bicycle. Anything I should be concern about?
