Disc brake question

No, this has nothing to do with wheel ejection (THAT argument has been thoroughly driven into the
ground (pun intended)).

The question I have is about installation and compatibility. The bolt holes on my frame and forks
are 51mm apart (center-to-center). Is this standard for all DB's? or is there more involved?

Sounds like they're the standard mount. What bike/fork?

some of my friends love their avids, and they stop you just fine, but i prefer hydraulic. much
better modulation.

I've only ridden a friend's hydraulic brakes around the parking lot, so don't know about that. I do
know I liked my Avids. Probably not quite as nice as some of the hydraulic brakes, but there's also
a lot less that can go wrong...

No, I don't want to get into a flame war with you hydraulic guys so calm down.

No flames, but an opposite experience. I've been riding bikes with hydraulic brakes for a few years
now. The Hope Minis on my XC bike have been zero hassle in that time. I've had some minor problems
with my Hayes on my DH bike but more from abuse than design flaws. That and I don't mind working on
them. I have tried a bike with Avids around a parking lot, and while they worked well, there was
still the feeling of friction and sponginess from the cable pull that V's and canti's have.
Hydraulics have none of this and transmit a better 'feel' from the caliper. The bike with the Avids
had been ridden agressively for some time (IE. not bike shop new) and probably needed new housings
and cables.

Rocky Mtn. "Reaper" frame, RockShox "Judy SL" forks. Is this significant, or are you just curious?

BTW, although they weren't asked for, I will take the comments over hydraulic vs. mechanicals into
consideration. The main reason I'm leaning towards mechs is

1. They are simpler, and wires are easier replaced than oils and lines (especially out in
the woods).

2. I'de like to be able to keep my Delta bar-end brake handles.

3. (touched on by #2) The brakes aren't bundled with the handles. i.e. you have a wide variety of
levers to choose from.

Just trying to figure out if your bike's new enough to have standardized mounts or not.

That's why I picked them. No leaks, etc...

sure, a cable is more easily replaced in the woods, but hydraulics are /very/ reliable and in some
ways more convenient. avids for example require regular adjustment of the pads as they wear.

as an analogy, the old pre-ww2 cars with cable brakes worked, but needed regular tuning. that
problem has pretty much disappeared since the switch to hydraulic. same for motorcycles. hydraulic
brakes for bikes, at least so far for me, have been wonderfully tuning free. just change the pads
when they wear.

and returning to the car/motorcycle example, countless millions of driver miles every year prove
their reliability.

lastly, there's not necessarily a significant difference in price. i got my xt's online for $99 each
set - including new lever, hose, rotor & caliper, whereas i'd paid ~$90 each for the avid calipers +
rotors [only] i'd had before.

What you say is true, BUT (and I stress BUT) we're not talking about cars and motorcycles, but
bicycles. Discs on bicycles are a new thing... Bugs not worked out yet.

My Avids were $59 and $69 from Supergo. Shop around some...

valid concern, but there's not a lot that's new. the piston, cylender & seal tecnology for both the
master & slave ends is old hat. the only thing about my xt's is the hose, but i'm not particularly
concerned. flexible hydraulic hoses of multiple designs have been around from the beginning too, so
i think manufacturers have a fair idea of what's going to work.

I agree that the technology's not new, just who is making it... There's always bugs, as evidenced by
a friend's repeated warranties of his XTs, as well as the stock brakes on his Scalpel. Admittedly,
the stock brakes were more of a problem than the XTs seem to be lately.

interesting! what problems?

i've been running xt's for about a year now and think they're wonderful. great modulation, stop you
on a dime, hardly any fade... the only problem i've had has been a *hideous* squeal from the stock
pads, but that went away when i switched to e.b.c. pads.

Off the top of my head, I don't remember. I'll ask him tonite while we're watching the game.
