Sorry for the basic Q's... appreciate links to FAQ's etc.
I have about 15 rides on my Trek Sawyer, it has "Avid Elixir 1 hydraulic disc brakes"
I've noticed now that there is a fair amount of "play" in the levers before the brake is engaged; this was not the case when new.
Is this normal? What is the adjustment I should make?
Also - can someone explain to me the advantages of hydraulic vs cable-actuated disc brakes?
