    Default 2000 Chevy Silverado caliper? Torx? Allen?

    I need some help folks- I'm just trying to remove the old brake pads
    in my 2000 silverado 4x2, and to do that I need to remove the caliper
    mounting bolts, which appear to be a torx bolt, although an allen
    wrench could also fit. The largest torx bit I can find at home depot
    or lowes is a T50 bit, and it's too small. A 10 mm allen is too big,
    and an 8mm feels too small, and like I said, the bolt looks like it's
    supposed to be for a torx and not an allen. Anybody want to send me an
    email and tell me the proper tool? Anyone know who sells extremely
    large torx bits? Thank you.

    On a side note (but I'll still take your advice ,
    Regarding the 'caliper mounting bracket bolts' which are 17 mm I think
    (and not the same as the 'caliper mounting bolts' torx problem I ask
    about above) - anyway, they have never been removed, and today I tried
    to remove them applying 170 ft-lbs of torque and the damn things
    wouldn't budge. Anyone else have a problem with these being
    overly-tightened from the factory and what did you do?

    Please email me at cwr43..........m at your earliest covenience.
    I want to finish out the job tomorrow morn. thanks-

    I believe it is a 55 torx bit.

    Never had a problem with them being "overly-tightened" from
    the factory...but....I have found them to be extremely tight due
    to the heavy duty lock-tite they use on those bolts from the
    factory. It's just the way they are...I use a quality socket and
    a 30 inch swing handle....they come off....

    I think GM may be somewhat standard across the board, my 94 Jimmy is a
    3/8" hex or allen wrench. You can buy one that goes on a ratchet like
    a socket does, only the business end has the allen wrench. Best bet,
    go to a parts store, say you need the brake tool or wrench to take the
    caliper off and tell them the truck. Any parts person worth his or
    her weight should know exactly what one you need...

    Thanks to Shiden-kai and and Tom for responding. For all those wanting
    to know, it was a torx T-55 bit for the caliper guide pin. Interesting
    note is that I drive my truck hard and brake hard, but don't haul many
    loads and at 50k my front pads were still at 70%. Rears were about
    40%. Anybody else have input about front brake pad wear in a 2000 1/2
    ton siverado? Wondering if I got lucky...

    No, this is normal for the new style trucks. I have yet to actually
    replace front brake pads on these trucks for being "worn out".
    I've seen trucks with 100,000 miles on them that still have over
    50% pad left. What I'm finding is that the front pads usually
    start to stick on the sliding surfaces of the caliper support and
    then one or more of the pads no longer is in contact with the
    rotor. Then the surface of the rotor begins to rust. So then
    we end up performing a front brake job due to this
    "seizing" problem, rather then actual front brake pad
    wear.

    Personally, if I owned one of these trucks, I would be
    dis-assembling my front calipers and pads, cleaning up
    the sliding surfaces (which are actually removable shims)
    and lubricating all the moving points every couple of
    years. I suspect that you would never have to replace
    the pads over the life time of the truck if this was done.

    Rears are another story. Usually, the right inner pad
    is the first to go. We do rear brakes all the time on
    the new trucks. Thank goodness, or brake jobs would
    simply be non-existent on these new trucks. Wouldn't
    want that, now, would we?
