Disc brakes squeal due to loose pads?

- Going down a grade that's slippery and/or covered with
loose stones you'd be able to walk a finer line between
washing out the front wheel and not having enough
braking power.

And not saying anything about how they are'nt bothered when you suddenly get a warped rim.

In the old days i.e. 20 years ago all brakes were lacking
power in wet conditions. Campy even in the dry :) Now days
dual pivot solved that for the road. Vs solved that for off
road. I have never ever had any problem stoping or even
locking up a V brake in any condition. So how can a disc be
any better? Disc are nothing but a fancy gadgit. They are in
the same vain as those spinning hub caps you see on hip hop
suv's. Cool factor. As far as Vs working with a bent rim. If
you bend a rim that bad the frame will prevent you from
riding. Discs have so many negatives & no real positives.

Then you need correctly designed and adjusted rim brakes.
Obviously a bad brake of any design is inadequate.

Our man Cholina weighs a great deal more than you and can
get the effects I describe with rim brakes.

This does not sound like a typical situation for _road_
rim brakes - not that I have any difficulty modulating my
front brake.

Actually, I have a conventional cantilever on the front and
a Suntour SE cantilever on the rear; so by my argument, I
didn't leave cantilevers because they do the job well.

If people prefer the relatively easy adjustment of Vs
to the relatively long pad live of cantilevers, that's
fair enough...

Perhaps you missed the words "road rim brakes" above.

evan & david & the other doubters - you are entitled to your
opinion, but /please/ don't dismiss the experience of others
without cause. rim brakes are fine for the majority of users
and in moderate conditions, but /never/ try telling someone
that's had to change rim brake pads half way through a muddy
ride that rim brakes are superior to disk.

it's disks that allow you to ride for three hours caked head
to toe in mud and filth and never miss a beat. rim brakes,
when the mud is truly smeared all over the rim acting like a
lubricant, just don't work, even with a death-grip. disks,
being up out of the goop & with their drilled surfaces, just
don't have this problem, hence they are superior for extreme
conditions.

and that's why people in this thread are taking a contrary
position to you - they are relating their experiences.

thanks.

Evidently you missed the word "road" too. Check with your
other sock puppets to see if they saw it, "tux lover" ?

That's great, but there's people out there saying
categorically "disc brakes are ****." In more extreme
conditions, discs are probably the best choice for braking.
All most other places and for more moderate riding, y'all
are right: discs are overkill.

If I lived somewhere where it rained LOTS and I HAD to ride
in it, I'd have discs on my road bike too. There's nothing
like being able to stop without having to squeegee the water
off the rim.

I live in San Diego, so I'm happy with the performance of
my road calipers. In fact, I was tickled pink with the
performance of my Dia Compe BRS200s (single pivot) for
many years. The only reason I'm not still riding them is
that they went to my little brother in VA. Who is still
riding them!

I can still remember almost flipping myself over the bars
shortly after DP brakes came out and I upgraded one of my
bikes. I was used to grabbing a fistful of brakes. The
DPs allowed you to grab fingerfuls of brake and do the
same thing.

Dear David,

Perhaps you ought to say "paved road" or throw a tantrum?

I am not responsible for all the people "out there",
thank God. :)

The only reasons for putting disk brakes on a road bike that
I can think of are

- Reliability in the rain
- Being immune to a taco-d wheel
- Not exposing the sidewall to failure after a crash bends a
pad enough so it's bearing on same and the rider is too
dumb to have checked before riding on (don't ask where I
got that one....)
- Interchangability with other bikes...

But these are all stretches IMHO.... Frankly, I think I'd
even be just as happy with a v-brake on the rear wheel of my
FS if it weren't for my non-standard calves banging on the
control cable...

what has "road" got to do with it? you're making blanket
condemnations of disk brakes and i'm merely pointing out
that my experience with them has been extremely positive.
exactly why this should trigger a hostile response from you
is something i have trouble understanding.

and you, of all people, should be able to figure out the
connection between "tux lover" and my choice of o.s.

Don't let him get to you. I think he just likes being
contrary just to be contrary.

I'll do the same thing, but I'm not quite as snooty
when I do it.

On the road one will not have to change rim brake pads
halfway through a muddy ride.

>you're making blanket condemnations of disk brakes

This is not true for two reasons; firstly, I am discussing
road use, in response to another poster's use of "road rim
brakes" (so not "blanket"); and secondly, I am merely
pointing out that they offer no advantages (so not
"condemnations").

I've not time for sock puppetteers, especially ones like you
who have obviously changed identity merely because the old
identity was correctly identified as a nutcase.

And you're sure of this? I know that if you ride a pair of
ceramic rims with normal pads, sometimes you do have to
change pads after one ride. Ditto with carbon wheels. I have
firsthand experience with this one.

Conceivably, if you do go ride a muddy road on a road bike,
you COULD have the situation where you'd need to change
brake pads pretty quickly.

Not that a road bike would do real well on a mud-fest ride,
but that's another story. A cross bike maybe, but not a road
bike with slicks.

Dear David,

This is not true for two reasons.

So far, you've had time for two replies, the second
amusingly claiming that you have no such time.

Even more entertainingly, Jim isn't the one who looks like
a nutcase.

Cheers,

Insert a "without demented equipment choices" if you like. I
get thousands of miles - in urban conditions, so with
relatively frequent braking at traffic lights, etc.; and I'm
not averse to the occasional impromptu expedition into mud
and gravel off-road.

I expect with any basic design of brake you can get a
defective model and setup which chews through pads quickly.
