    Disc Brake Question?

    How long will they last till you need to replace them ? I am very new to MTB so forgive the question. Also I heard that if you remove the tire and accidently squeeze the brakes it will lock them and require servicing at a dealer. Is this true or can I unlock them myself... Thanks again

    The lever squeezing problem is only for hydraulic disc brakes, if you have mechanical disc brakes then this isn't a problem at all. And yes, you can easily re-set them yourself using a flat head screwdriver and prying the pads apart very slowly and carefully so as to not break anything.

    How long do they last? It all depends on your use, I know some guys that use them for 2-3 seasons in a row, and some that burn through them in 2-3 months. There is no sure way to tell you how long they'll last.

    I saw from the other thread you are getting a Trek Hardtail. I'm not familiar with the model you are getting, but I started a couple years ago with a cheaper Trek hardtail with mechanical disk brakes.

    I weigh about 200 and I went through brake pads about every 500 miles on that bike. On my newer bike I have hydraulic disk brakes (and more skill) and the pads are still good at the 500 mile mark.

    The first response to your question covers the question of closing the brakes with the wheel removed. My newer bike came with a plastic wedge to push apart the pads. A knife blade or a small screwdriver would work just as well, I think.

    It also depends on the pad compound you use. If you use a metal pad with, say, titanium rotors, you'll screw the rotors up pretty bad pretty quickly.

    For racing I run black pads on XTR rotors, which will wear through much quicker than what I use for practice/training - green pads on Avid G2 rotors.
    In the wet however, I'm well aware that a single enduro could wear through an entire set of blacks.
    Reds and golds I don't really use, though there is the trick of using a black on one side and a gold on the other side for better performance - these will of course wear at different rates.

    As for being told they needed servicing at a dealer if they were pushed in, who told you this? A dealer hoping to make more business? Most multitools will have a flat lever, or a stanley screwdriver will do the trick (just be careful not to damage the pads).
