WhyFi would know. Fat new pads definitely help.
My understanding is that DA and Ultegra allow adjustment of brake lever free stroke, but 105 does not. I have the same issue on my Canyon, that over the 1500 miles I've ridden it, the free stroke has increased, especially at the front. I THINK what's happening is that as the pads wear the return springs are still pushing the pistons back to the same place, so the free stroke increases. It's a little disconcerting when I switch from my rim-brake bikes, because I like to keep the pads close to the rim so I get bite with just a little lever travel.
I know people will tell you that disk brakes are supposed to be self adjusting, but I think that's if there's no return spring, like in cars. I should take pictures of the gap when I change pads and then look at it a couple hundred miles later.
