To adjust the position of the movable member relative to the fixing member, just loosen the fixing bolt member to disengage it from a threaded hole on the fixing member without being moved out of the movable member, push the movable member to a desired lower position, and then tighten the fixing bolt member against the fixing member again. The brake block…
