Went riding in Wales over the weekend with a new set of XT brakes. Set them all up before I went (gave them a bleed, adjusted pad contact etc). and they were great to begin with. But as the weekend went on I found I was having to pull the level further and further towards the bar before they began to bite.
Now there seems to be quite a bit of dead stroke before the pads actually make contact with the rotor. Is this a common issue in these brakes, and if so are there any remedies?
From having a quick look last night in the garage it seems the springs holding the pads in are doing a good job of pushing the pistons back in. But could I get away with less springiness to try to eliminate the dead stroke? Or is there a better way of bleeding the brakes so its more effort to return the pistons - therefore leading to the pads being moved not such a great distance from the rotor?
Any help appreciated. Cheers.
