I have these on 2 bikes and for the price, I can't complain. They have great stopping power, were simple to install and adjust. I bled one system and it wasn't nearly the pain in the culo that I had anticipated (do a little research before you do).
There are better brakes out there now, lighter and slimmer, and most likely more expensive.I've never regretted buying these.

Strength:

They do great almost all of the time. They slow you down..enough. Awesome system that rarely needs bleeding. Excellent mid-range brake. After riding these a hair over 3 1/2 years, I have been impressed with the performance.

Weakness:

That dang hayes wobble. theres a good quarter inch of lever play in both levers. levers are a vulnerable arrea for damage. knowing that, I got the brakes anyways (carbon fiber = shiny factor), and the clear coat has chipped off in numerous places. Ive found that the v6 rotors dont seem to get the job done too well, so i ordered up a front v7 rotor and 180mm adaptor, hopefully that will fix the two finger lever issue. They tend to make noise in the rain, but what brake doesn't? they have too much neutral lever pull, and even after I bled the brakes after 2 years (super nice, sealed, reliable system) the lever pull didnt change much, but then again, there wasn't much air in the system to begin with. the rear brake is a pill though. i was experiencing fade, so I bled the rear system,and the fluid was this milky grey color, so i flushed the ststem, and there is still continuing fade... the front brake packs up a bit, as opposed to fading.

For an excellent low maintence, mid range brake, this is a wonderful option for a cross country to all mountain bike. sweet price, mad shiny factor. will stop the bike. theoretically.

i would suggest the new Hayes Stroker line as a step up and comparable price.

because of the new stroker line, i give this brake 3 chilis.

Strength:

The carbon levers have a good ridgid feel. The pads really seem to last a long time. Reasonably light and look good. Good modulation and quiet.

Weakness:

Too much lever travel for my liking. Not powerful enough for extended or high speed downhill runs. Not quite a one finger brake.

A great brake for xc use and short downhill runs. However, i have found the front brake requires too much effort to get the wheel to lock up.(really, how often do you go around locking the front brake anyway?) The back brake will lock up fairly easy and has been great on all but the long steep downhills. I weigh 130 lbs and on a fast downhill run the rear brake will be literally smoking! Also the rotor is black and you can feel the heat radiating out. The front dosent get as hot but it is way too hot to touch. All things considered, I feel that Hayes made a great product for its intended use but it dosen't quite fit the needs for long/fast downhill runs.

Strength:

Easy adjustment, no maintenance, not the heaviest, nifty carbon lever, it works

Weakness:

moisture + brake = squeal, not the strongest, not the lightest

These have worked very well for me here in the desert. I've got ~1500 miles on them with no mechanical problems whatsoever. They have great modulation and feel, and my only complaint is that they could use a bit more power. While they always seem to stop my 185lb self + 30lbs of bike, I would like it to happen a little quicker.

Overall a pretty decent brake for the $$.

Strength:

Only cost me $90 and it has a carbon fiber lever giving it that cool look

Weakness:

ALOT OF WEAKNESSES FOR ME! first problem i encountered was when my master cylinder screw completely stripped and my brake lever hung loosely unattached and i had to pay $40 to get a stupid screw? next problem is that my brakes have completely faded out even after a completely thorough bleed.

i would not recommend this break it looks cool but the power fades to quickly and it feels really cheap i am definetly not satisfied

Strength:

Solid, easy to adjust hose length, carbon levers have high 'bling' factor, easy to adjust/set-up, reliable, easily repaired/simple design, plenty powerful enough for XC use

Weakness:

During long descents they can be a bit noisy - more of a high pitched hummm rather than squealing, if you're not careful you can break the piston/post that holds the brake pad when pushing the pistons apart... but it can be fixed easily enough. Bleeding is a bit of a pain - but once you do it it's no big deal - I recommend using a big syringe instead of the bottle they give you. No major weaknesses though

I was given an older pair of Nines a while back and they worked great - then I broke the post on one and had to pull the caliper apart to replace the piston and seal...which was straightforward enough, so I got another pair since I knew I could fix 'em and they were on sale for $79 each. They have proven to be plenty reliable and are WAAAAAY easier on my hands on long descents than the BB7s were.

These are good "workhorse" brakes for XC use and have stood up to some good abuse.

Strength:

Looks great! Brakes very well with 8" front rotor.

Weakness:

Terrible machinging for the brake adjuster screws...backs off after 15-10 minutes

The brake adjuster screws are out of spec or the threading is out of spec...Constant adjustment of the brake lever adjuster is necessary. This is my 1st Hayes product I have owned and it will be my last, should have insisted on Shimano from the start. 1st gen XT discs are where its at.

Strength:

Lever feel
Stops like a stick in the spokes

Weakness:

The front one suddenly started pulling all the way back to the bars with almost no stopping power. So into the local (very helpful bike shop- cheers Cyclex) bike shop I go. They said it probably needs a bleed, perhaps some stuff in the lever needs replaced. No worries. They bled it and lots of “black crap" came out, replaced the cylinders in the lever, still no change in the performance, bled it- more black crap. They got on the phone to Hotwheels (the importers) who want it sent back to fix. I would be less worried about this if the mechanics hadn't encountered someone else with the same problem at the meridia 100 this weekend.

These came on a year old hire bike from the hub. They feel and work great, however...see the weaknesses

Lets see how this problem gets fixed. A £50 repair bill (so far) on a brake that can be replaced for £90 is not looking great.

But when they work, they work well:)

Strength:

Amazing modulation and power, damage resistant levers

Weakness:

I eventually broke off the piston inside the caliper and had to rebuild it, not too hard or expensive though

Simply amazing brakes, nothing can beat their modulation and they have plenty of power, you can lock up the wheels using only 1 finger if needed. I have used the regular HFXs a lot and there is a noticable improvement with the carbons, the levers dont break off or bend as easily, and they are better shaped so there is no need for a bonz or dangerboy lever.
