Strengths:    Look Good

Weaknesses:    I think I got a bad set.
After the fifth brake bleed and a hose swap + multiple pad/rotor combinations I gave up on them, they just would not bite in the good way, only the bad way. Got the newer 675 version and all is good. Both the front and rear were weak and not as powerful as my BB7's and cheap Tektro hydraulic brakes. (Had a 180mm rotor on the front BTW.)


Bottom Line:   
As a shop mechanic I have worked on many shimano brakes for customers and never had the problems this model of mine had. New version is great.

Weaknesses:    Haven't found any

Bottom Line:   
These came on my Fuji Outland and I have very impressed with them. They have taken some hard hits that would have damaged some other brands, but my levers and reservoir are intact and working great.

Strengths:    Initial fit and feel is great. Using them with Avid 185 rotors and they match up well. Break in period was effortless and they have great power, I will switch out to metal pads in the front this summer for even more stopping power. Modulation is better than the Juicy sevens thay are replacing and zero turkey worbble noise.

Weaknesses:    I grew to like the Avid bar clamp system, Shimano is single bolt slide on. It holds in place well but for on/off ease avid is better.

Bottom Line:   
So far these have been a very good buy. Initial power and feel is excellent. There is a lack of "Avid" noise that I grew to except as normal with the Juicy set up. I'm glad I bought these. I may buy a second pair for down the road at the price they are going for.

Date Reviewed: November 30, 2010

Strengths:    - Reliable on the trail, never faded on 185mm rotor (had no problems with leaking, riding in low temp. conditions)
- really easy to bleed
- good cheap aftermarket (superstar) pads
- pads retract far from rotor, so no rubbing on the rotor (servowave)
- silent in dry conditions, but on wet resin pads make some noise while breaking
- lever position (not that I've used it a lot, once positioned, didn't change it after - if too close to the bars, the brake will have less power so no use from this)
- great modulation (best I've ever seen on disc brakes)
- easy to change pads (pistons retract easily, not like on Juicy 3 where you need to remove some fluid from the brake)



Weaknesses:    - average power (I'm 83kg with 185mm rotor)

Bottom Line:   
No other weaknesses really, but I'm little disappointed with the power segment. I've had Juicy 3 on the front that had a little less power than the SLX with the same size rotor - 160mm Shimano. SLX with the 185mm rotor gave some more power, but still nothing like one finger brake-ing on Avid Juicy 7 or Elixir brakes (if working properly) that I have tried. I could do a "stoppie" (getting my rear wheel of the ground while seated)with two fingers on the brakes (185mm rotor) and pulling it hard.

While on my brothers Juicy 7 and my friends Elixir CR I could do a "stoppie" with only one finger and with ease. But Avids have a lot of other problems (vibrating, squealing, factory bleeding is bad etc.).

Maybe I'm having trouble with my rotors ? Cause I have a feeling that the brake is very powerful, yet the friction coefficient between the rotor and the pads is low :(. Tried it with Shimano 160mm rotor (Deore class ?) and Avid G2 185mm with the Avid adapter.

About the pads
----------------------
Original Resin type pads lasted 1300km on the front. Very fast brake-in period (5-6 hard stops) and you have a fully functional brake.

Tried sintered from discobrakes - brake-in period is a lot longer (not knowing that, I've sold them after 60km thinking they are low power, but while removing them to send them to the buyer, I saw that they have braked-in only on the edges, and not in the center - probably needed some 50-60km or one great descent to be fully functional). They could easily be used on the rear where you don't need a lot of power pads since every hidraulic brake/pad can lock the rear wheel (even my Juicy 3 with 160mm rotor can do it =)). And would probably last more than the resin pads ;)

Then got organic from superstar. They are cheaper than the original Shimano pads, have the same power, same fast brake in period but I don't know how long will they hold. I' would be happy if they last 750km in dry conditions, since they are 3x cheaper than the originals.

Overall rating is higher cause you can use a 203mm and have decent power and they are problem free brakes, low maintenance, easy bleed, great modulation.

Strengths:    Super Powerful, easy to bleed, Its Shimano so parts are easy to come by, easy to set up, and they LOOK awesome!

Weaknesses:    Only problem I have had so far is with the rotors. I have the splined versions, and where the rotor is rivited to the body it has a little bit of play in it. I got these replaced under warranty so all good, BUT the new ones have this too after only 2 months use. I'm going to upgrade to the XT rotors and see how they go. But otherwise these brakes are brillant!

Bottom Line:   
These brakes are brillant, apart from the rotors!

Strengths:    Best brakes ive had by far.
very powerfull, no fade halfway down descent, very reliable, im very happy


Weaknesses:    A little hard to feather in wet conditions, slightly on off due to how powerful they are.
the pads that come with them are rubbish (resin fibres), changed pads to sinterd and wow what an amazing brake!
also the hoses are really long and need to be cut down.


Bottom Line:   
LOve these brakes, seriously good value and so so powerful!

Strengths:    Cheap, plenty powerful, ridiculously easy to bleed and swap pads.

Weaknesses:    Took me quite a while to get everything set up right, lots of tinkering and tweaking to get rid of massive squeal and "crunchy" lever feel... but great now.

Bottom Line:   
Great brake, inexpensive, so easy to bleed and change pads a cave man can do it (shame on you Avid!).

Maybe you can learn from my problems:
1. Front was squeeling like CRAZY, i'm talking like laying a car horn on any extended DH section, enough to send the wildlife into the next county. Resin pads seem to have resolved this.

2. Crunchy lever feel. Took me forever and some frustration to figure this out. The metal pad backing slides against the inside of the caliper body and was making a horrible crunchy/grinding/jank feeling when the lever was pulled. Clean streak the hell out of the caliper body (no pads in) and sand the edges (front edge) of the metal pad backing with some 220 wet/dry sandpaper. Also the XTR pads seemed to not have this problem (they are Ti backed not steel.)

Bottom Line:   
**Review is for the SLX 203mm Brake Rotor ONLY**

I purchased this larger rotor for the front of my bike, and once I got the correct mounting adaptor, slapped it on. For the most part, I was happy with the stock Shimano M486 Hydraulic brakes that came on my Piranha, at least for casual and spirited XC. However, some of my favorite trails around here are quite technical and there are some wicked fast downhill sections. Occasionally, I would experience brake fade and just not quite the stopping power I needed.

This larger rotor is an amazing upgrade for the price. It's almost as if I have a whole new brakeset on the front of my bike! Stopping force is probably almost twice what it was with the stock rotor. Installation was a breeze.

Shimano's SLX line of components is really beginning to impress me. I think I'm going to have to get a matching 160mm rotor for the back now!

Strengths:    They work, for one. Good modulation, good power, low fade.

Weaknesses:    Too much lever travel for my tastes.

Bottom Line:   
I gave the Quad brakes that came on the Heckler a chance, and they seemed OK, if not as strong as the old XT brakes I had on my previous bike. Then I went to the ski hill (it's small, so not like doing Whistler) and they got scary. By the end of each run the levers would be to the grip, and it was getting worse as the day went on. I decided to not mess around and went back to Shimano. SLX parts can be had in Korea for not much more than in the US, unlike most other things, and pads are available, so that sealed the deal. First day back on the ski hill and I had no more fade issues and was not worrying about my brakes all the way down. Priceless!

Strengths:    -Stylish
-Easy to install
-Easy lever reach adjustment
-Stop nicely
-Quiet


Weaknesses:    The only problem I had is also a strength. The brakes came prebled and ready to install. The problem is that my brake cables route through the frame's rear suspension. I had to disassemble the rear suspension to fit the caliper through the frame.

Bottom Line:   
I am 100% pleased with my purchase. I researched Juicy 7s, Elixirs, Strokers, and Shimanos. After ready the reviews on the problems associated with the Avids and Strokers I narrowed it down to the Shimanos. It was a toss up between the SLX and XT discs. I soon realized i would simply be buying the "XT" logo if I went with the more expensive XTs at $300. I ended up ordering a set of SLX from blue sky for $200.

My old mechanical Deore brakes seemed to be either on or off. After the first ride with the SLX brakes, I realized what I was missing. I rarely locked my brakes up and was in full control of my bike's speed.

I never knew hydraulics were this different than mechanical brakes... Then again, it could be that I was just using really low end mechanical discs.

Strengths:    High quality, very reliable and does what it is designed to do. Has a bunch of stopping power with very comfortable feel.

Weaknesses:    haven't seen any weaknesses yet..

Bottom Line:   
Shimano has always been excellent in terms of quality and performance. Price is reasonable(depending on the model category). Some products are also good but way too expensive(you're just paying for the name! it's the character not the brand). You can't go wrong with the Shimano SLX.
