Deore vs LX vs XT V-brakes

Jasper Janssen said:

Quick check: Is there any reason to want LX or XT brakes rather than
Deore, when buying new? Price difference is fairly minimal, but present.

I read something about XT brakes being the only one of the set to have
parallelogram linkage which makes them need less readjustment over the
wear life of the pads. Given that I probably won't be getting any mud on
this bike, so the extra parts to wear out aren't so much an issue, and I
think it might be *nice* to have that, but it seems that opinions are
divided on the usefulness of the feature.

LX also have this. It's good for keeping the pads aligned as they wear,
less good for squeal.

LX it is, then. I like tinkering, but there are weeks or even months where
I really need the bike to just keep going with minimal effort. And
squealing just means the brakes are working right.

The new LX don't have the parallelogram linkage any more. I always found
that the parallelogram construction was [censored] and made things too
complicated; to many joints.
I would look at Avids too.

I didn't know they'd dropped parallel-push from LX. I purposely got
Deore to avoid it.

I've heard it gets worse with age, as grit starts to wear the pivots.

Exactly. Stupid construction IMO. My simple Avids were better and more
durable than the XTR's.

Aside from things like this, where is the quality difference between an LX
linkage-free vbrake and a Deore (or for that matter Tourney) one? V-brakes
would seem to me to be mostly *so* mechanically simple that it would be
extremely hard to effectively design half a dozen different quality
levels, such as Shimano really needs for its marketing. Are the brake arms
of pricier brakes stronger? More adjustment for the pads?

Yes they are simple. They are just levers. Differences?
Finish, cold forged or not, cartridge pads or not, stainless steel or
even titanium bolts and other bits and pieces, little weight, ball
bearings or plain bearings or no bearings.
What I can see comparing LX to Deore is that LX has cartridge pads,
nicer finish, maybe stainless bolts and it's a little lighter.

They are just brakes you know. Peanuts in the total cost of a bike.

My XT-V's are 5-6 years old, never had any problems -- perfect (1
finger) braking.

Quoted message said:

Lucky you. In what condition do you use them?

Exclusively off-road, much more trail/singletrack than fire road, I
rarely ride them in wet conditions.

Quoted message said:

My XTR font brake became
so sloppy after 3 years that it became dangerous (pads almost hitting
the tire).

No experience with XTR, never could afford it.

Quoted message said:

One finger braking has more to do with conditions, levers and cables.

I have XT levers (would think that was typical), nothing special for
cables. Brakes seem to work the same in all the "conditions" I ride in.

I couldn't get rid of very loud, polyphonous (high-pitched squeal plus
lower organ-like tone) brake squeal with XT brakes--greasing pivots,
using Kool Stop salmon colored pads, etc., nothing helped. Assuming that
play had developed in the parallel linkage, I changed the front brakes
to Deore, without the parallel linkage. The dealer mentioned that he had
made the same change for a customer that day (and offered a set of Deore
brakes cheap...). This cured the problem.
