$50.00 | | Purchased At: | ebay | | Strengths: | Brake point and power with little finger power | | Weaknesses: | does not fit very well with SRAM trigger (older version, I have 3 of these), IS2000 (instead of PM), fade a little on long runs | | Similar Products Used: | Hayes HFX 9, Magura Luise, Magura Julie | | Bike Setup: | Used on a KHS AM-1000 and a Rocky Mountain Thin Air. Both completely custom built | | Bottom Line: | These brakes work just great. Two of them are with 160mm discs and one with a 180mm. Bleeding is not a hole lot of fun, but that applies to all hydrolic brakes. As written bellow, when using the torque recommendations there is no problem with them breaking. The bleed skrew does not have to be very tight! I use them with Kool Stop pads and they never failed. Just fade a bit on longer runs. | Value Rating: Overall Rating: |

Everyone that says "you can't turn your bike upside down with these brakes" obviously doesn't know how to bleed these brakes properly. All you have to do is push down and "burp" the rubber gasket before you put the master cylinder cover back on. This prevents any air from entering the system.

Got mine second hand, together with my bike, and I biked for >10.000 miles so far.
They only needed servicing every 4.000 miles or so - bleeding and changing the plates. That means, they didn't need service for years, even though I biked more than 15 miles per day, through snows and extreme hot days! | | Weaknesses: | Bleeding screws easy to break. However, even with the bleeding screw broken, I could perfectly bleed the front caliper.
In very hot days, the fluid can expand and gently press the disk, causing a slight brake. That might also happen during extreme rides, due to the extreme heat released when braking. | | Similar Products Used: | none | | Bike Setup: | Frame Haro Dual Slalom, Manitou X-Vert T dual crown, equipment XT, chaindog Truvativ, rims Vuelta Excalibur, tires Jumbo Hutchinson 2.45" | | Bottom Line: | Take care of them and they WILL take care of you.

Had been bled so many time due to lost power, it's now leaking by the reservour and I also damage the screw.
I just change the rear break with Avid Mechanical Disk yesterday and will try it out tomorrow. I bought this break due to great reviews by other riders and also I'M TIRED OF FLUID LEEKS!!! and maintenance. Look for my review on the Avid Mechanical in a the near future.
The Grimeca System 8 came with my bike, it works great when it works but when it doesnt like my reak leaking during my last ride(lost 80% of breaking power) I end up on a ditch cause my front break did all the stoping.
I'll give it 4 chills for stoping power when it works but overall 3 chills due to problem I had with this break.

Date Reviewed: August 11, 2003 | | Duration Product Used: | Less than 1 month | | Strengths: | Great feedback and stopping power... | | Weaknesses: | Mechanical expertise and maintenance | | Similar Products Used: | Shim | | Bottom Line: | First off - most mtb riders don't know much about hydraulic brakes [take this from a X-motoX-er]. These brakes are fantastic at stopping - provide incredible feedback and are quality built.
However, they are less durable then a pair of standard pad brakes AND require some knowledge and mechanical ability.
Without proper bleeding - the brakes won't work. Without regular bleeding and/or maintenance - they'll weaken over time.
So if you have the know-how - these are fantastic brakes for the bling. Otherwise stick to diapers and standard pad brakes.

Date Reviewed: June 2, 2003 | | Duration Product Used: | 1 Year | | Strengths: | Once problems were resolved (see below) the brakes seem to work well.
Comfortable levers and modulation feel.
Brake pad replacement is easy, and once the calipers are lined up, no brake adjustment has been needed.
| | Weaknesses: | Initially there were many. Brakes came on my bike, and the brake fluid was leaking from the levers, causing the paint to peel off.
Additionally, the rear caliper was slightly leaking fluid from the bleed screw.
I sent the brakes back to the distributor (Vuelta) and the levers were replaced with newer versions which have not leaked or caused me any problems. (yet?)
However it took an email to the manufacturer (in Italy) to get the distributor to replace the rear caliper. (this took time and caused frustration).
To be honest, I'm not sure how much better they are, or are not, from V-brakes, since I went from an old bike with cantelever brakes to these disk brakes. (never really rode much on V's).
That said, if they aren't any better than V-brakes, probably don't need the extra weight, and potential headache. | | Bike Setup: | KHS Team ST (great frame) | | Bottom Line: | While disk brakes look pretty sexy, I spent a lot of time dealing with the distributor/manufacturer trying to get the brakes to a satisfactory level.
Since getting the brake issues resolved, I have not had any problems to speak of and have been satisfied. (I hope it stays that way)

$165.00 | | Purchased At: | www.trident-sport-usa.com | | Strengths: | This review is for the system 12 | | Weaknesses: | How much time do you have?
stainless steel fittings will snap like a pretzel, poor instructions at best | | Similar Products Used: | Hayes hydros w/ 6" rotors | | Bike Setup: | Giant Ds1 warp, race face cranks, rock shock phsylo, Grimeca (Vuelta) DH wheelset | | Bottom Line: | To be fair, I belive that Grimeca has adressed many of the problems that the system 8 had. For instance, I didn't feel like I needed to bleed the brake out of the box. The only thing that they failed fix, is the pretzel hose they use. On a steep, rocky hill, I went over the bars (at a very low speed) and the bike flipped over to the side, twisting the handlebars around. When I picked up my bike, the cable was snapped at the banjo fitting next to the resivor. So basically, the weight of the bike was enough pressure to snap the line. I couldn't belive it because it was such a lame crash, I wouldn't even call it a crash. I went back to web site that I bought the brake and they contacted the tech rep in California. He said that basically it was an installation issue,(or my fault) Here is the email I got:
(trident-sport-usa)I told you that I would check with the head tech man at the Grimeca importer (Vuelta USA) in CA. Here is what he has to say:
(grimeca tech)To be honest, it does not sound like a warranty problem; this is the first time I have heard of this type of product failure. This tends to indicate that installation is the most likely cause of the product failure. Typically, rear brake hose length is 1500 mm or so, and the brake lever is installed at about a 45-degree angle (relative to a flat surface); the banjo fitting at the master cylinder/brake lever runs out in a (more or less) straight line from the lever and riders or mechanics usually carefully adjust that fitting by slightly loosening the hollow fitting bolt and moving the hose angle up/down as needed, and not by very much, because the lever angle can be adjusted instead. The hose, its fittings and mount bolts are stainless steel.
All that considered -- and the fact that we have some pro downhill teams that use System 12 without having this type of problem -- it bears repeating how unlikely this kind of product failure is. This is, of course, not what the customer wants to hear. But, unless there's proof otherwise, this is the only conclusion I can come to.
(I felt like asking him if he had ever heard of MTBR.com!)
of course if you can figure out anything he just said, the fist question I have is why isn't that in the instructions? (because it's not)
So anyway, its $50 for a new hose from them. But, there is good news, a sales rep for Jensonusa.com named Scott, told me that Grimeca brakes are the same as Shimano so I could purchase a new hose made by shimano and it would work. The best part is that the hose cost 9.95 and it is stainless steel braded.
The bottome line after all that, If I had my $165 again I would have bought Hayes. The people at trident-sport-usa.com have exellent costomer service, (and they sell more than grimeca) but I would'nt sell grimeca, their products and their customer service are grim at best. (This season I also purchased a set of their DH wheels with cool anodized red rims, and the rear hub is gone!) 1 season!!!!NOT COOL!

you can get EBC pads for them | | Weaknesses: | factory blead job (Oh friggen no!!)
none other | | Similar Products Used: | hayes, shimano XT | | Bike Setup: | GT avalanche, rockshox psylo sl, grimeca sys 8 with 8inch front rotor, XT, answer bar, mavic wheels | | Bottom Line: | Set them up right. If you dont know how or dont have the time have a bike shop do it. bleed them when you first get them. after that they are an incredible break and still send me over the handlebars. they dont fade on downhills and dont have a squeek problem like the hayes. same thing as XT's so if you like the environment and have more money there ya go. I would buy these breaks again. I love them, they are my best friends | | Value Rating:Overall Rating: |

$275.00 | | Purchased At: | bicycles unlimited | | Strengths: | modulation, good stoping power, no fade | | Weaknesses: | brake fluid eats paint | | Similar Products Used: | hayes mechanical | | Bike Setup: | canondale raven sl 1000 | | Bottom Line: | after the bike shop set this breaks up they have worked great. have not had to rebleed them and only had to change pads once. they are so much better than my old hayes mechanicals i can't believe the difference. it's important though to have a mechanic you trust to set them up right. | | Value Rating:Overall Rating: |

$200.00 | | Purchased At: | on a Rocky | | Strengths: | Product is 'XSIV' identical to Grimeace sysy 8
Works well, stops when you want to stop, loves abuse, no fade even when glowing - smells abit though. Same pads as shimano. One finger is all you need ( so the wife says) to do the job. Look good | | Weaknesses: | None, although hydro pipe routing a bit scruffy and open to those intruding branches
| | Similar Products Used: | Hayes mechs, RST mechs and hayes on a fisher | | Bike Setup: | Stndard Rocky Mountian slayer - if you could call it that ! | | Bottom Line: | Does what a brake should - this is throw you over the front when you pull hard enough with the magic finger | | Value Rating:Overall Rating: |
