Bought these cheap on eBay to fit my new disc only wheelset, big mistake going cheap. Seemed fine at first- not great but ok. Rode them a little to break them in, then took them to the trail one wet morning. In the rain they were worthless, like having no brakes at all. I had to drop my bike four times to get off the trail. I tried cleaning all braking surfaces with alcohol, sanding the braking surfaces, and breaking them in for a long time (multiple days). No help. Tried e-mailing Grimeca- NO HELP. Mabye their other lines are ok but these are crap.

Yes they do take a while to brake in, ALL DISC BRAKES DO(car motorcycle or bike) Yes dot 3 fluid will eat paint, but dot 3/4 will not fade due to heat build up( vegitable oil will ask your mom what happens when she cooks with it, ask any one with xt discs.They will fade as will any other brake on this planet if you ride with them partially on and they get excessively hot. taping your brakes( squeezing lightly then releasing,then repeat will get you down long steep descents safely if it is unwise to fly down. This helps with all breaks but you will experience less fatigue with disc.( I was an auto mechanic before a i was bike mechanic). Hayes is another good hydraulic disc and avids mechachanical disc is great to. stay away from magura and formula, I know bike shop mechanics that hate these, They rank up there with coda discs and Cannondale stopped using them because they sucked so bad.

$100.00 | | Strengths: | powerful, don't fade, no weak hands at bottom of downhills, inexspensive, obviously work well in wet, pads easy to obtain | | Weaknesses: | hydraulic disc brake inherently means that it cannot be left and forgot
risk of air bubble when bike upside down
uneven pad wear
takes a long time to bed in
requires regular bleeding
inherently less reliable than a mechanical brake
realistically you need to be able to bleed them yourself, otherwise you will spend a lot of time at the shop | | Similar Products Used: | Various v brakes | | Bike Setup: | 2000 Marin Rift Zone, 2001 Z1 drop offs, XT front disc hub with Sun Hill Rod, Sup 521 rear, front XSIV = Grimeca sys 8 disc, rear v brake, Deore drive train, Roox risers, Conti Survival Pro. | | Bottom Line: | The 4 pot system 8 took a long time to bed in, then provided good stopping compared to v brakes. Most noticeably at the end of a long DH and obviously in the wet. However, they aren't without fault. At the start of a race I had them leak from the top hose joint - my fault should have checked that it was tight, probably loosened in a crash - easily fixed when I got home but if you are miles from home it could make for a long trip back.
They are a pain to bleed due to the small reservoir and it is a messy procedure and yes hyraulic fluid is paint stripper and doesn't do your pads any good if spilt on them - for example when it runs down the hose. However I have found what seems to be an easier way of bleeding the air from the system:
Instead of bleeding in the conventional sense from the top down, I have started forcing fluid up from the bleed nipple using a 30cc syringe and flexible tubing. (Fortunately a standard syringe accepts the flexible tubing perfectly) Fluid will spill from the top of the opened reservoir so be prepared for this. Then it is a simple matter of using a spacer between the pads to ensure correct clearance, screwing the top on and away you go. I have seen bike mechanics bleed and setup the clearance with the disc in situ - this don't work. The disc has to be removed otherwise it makes for a very spongy feel.
Having adopted this method they certainly feel better than ever and you don't seem to be chasing your tail with an air bubble which makes its way almost out of the system before having to refill reservoir, only to have it migrate back up to the top.
When I first got the disc I made sure that I got a conventional rim with a braking surface, on long rides I throw in a front v brake unit, just in case something disasterous happens with the hydraulic fluid - doesn't weigh much and could make a big difference to the day. If only v brake levers had a 2 bolt clamp rather than having to remove the grips.
These brakes have only seen summer use so far hence not a lot of wet muddy tracks - which is really where a hydraulic disc comes into its element. Hopefully they prove to be an improvement in the long run. | | Value Rating:Overall Rating: |

Hydraulic discs add significant weight, and the Avid mechanical discs (I've just ordered) may work equally well and shave some weight ... we'll see.
When you're sick of V-Brakes, especially in the wet, don't waste your money starting with cheap hyd discs (especially don't buy a closed system or a cheap mechanical disc.) Most of the complaints I read here are related to cheap products (noisey, weak stopping, continuously needing tuning, overheating, binding, squealing -- it's all associated with cheapo products.) If you're buying discs, you're not building up a super-light or super-cheap bike any more, so be prepared to throw a few hundred at the kit.

Plastic coating on the cables. | | Weaknesses: | Just about everything else.
1) There isn't much more power than a good v-brake (although by default they are more consistent in the mud, a plus in the Vancouver area).
2) Uncomfortable levers
3) Confusing manual
4) impossible to get parts (which is deadly when the parts are of such low quality to begin with)
5) The screws that seal the bath are made of some of the softest metal I have ever seen. If you do get (or have) these brakes, beware of this or you'll strip the screws and be left with brakes that are even more useless than when they're working properly.
6) The bath is at an awkward angle to the handlebars.
7) Pad wear is totally uneven. Even with constant adjustment I always had one pad worn down to the metal, and the other pad looking totally new.
8) Poor customer service. These Grimeca fellows are in the motorcycle brake business. If you're looking for help with their product (and you will) you'll have a hard time getting the time of day from them if they find out your a mountain biker.
There are more issues, but those are my main beefs

If they worked, they'd be good cross-country brakes. If you're into more downhill flavoured riding, I'd definately recomend something with more power.
Maybe Grimeca will evolve this product into something more reliable, but I'll stick with a company with a customer service angle instead (although there was one helpfull guy at the NA distributor, I can't remember his name but he eased the pain of owning these brakes a bit). | | Value Rating:Overall Rating: |

with the dolomite disk wheel set the change from chris king hubs, tie spokes with a radial lace front and rear with a 3 cross drive,and ocr rims (very, very lite bomb proof wheel set) I only gained a 1/2 pound not bad for a weight weenie such as myself. the directions are very lacking, but the bleeding is the easiest of all the disk setups on the market, just dont suck air into the system when you do it. If you dont know how its easy.
With your brakes set up on the bike.... 1. take off the cover dont lose the screws or the rubber gasket. 2. get some rags and cover your paint job and take off any thing that might upset you if it melts, ie your computer.Also its a good idea to get a small diameter tubing a couple of feet long that will fit over your brake bleed bolts nipple so you dont spray brake fluid across your mothers livng room, remember,brake fluid will take paint off of surfaces and melt plastic. if you're a slob switch steps 1 and 2. 3. slowly squeeze the brake handle a few times and hold it down. 4. with the lever squeezed, open the little bleed bolt on the caliper, (make sure the rubber cover is off first) it should shoot out, be careful. 5. with the lever still squeezed close the bleed bolt. 6. release the lever, check brake fluid level, if its less than half, fill it or you will suck in air next time you try to bleed it, the best thing to use would be a little siringe with a small piece of tubing on it to fill the reservior. repeat until the lever feels good, if its still to close to the bar there is a 2mm hex bolt on the silver lever covered by a black cover that spins, spin the cover so you can access the bolt and turn it until the lever pulls back the distance you like, what you are doing is adjusting the plunger that enters the reservior. if you screw this up take it to a good shop and show them what you did and ask to see it down correctly, you will have to do this again as the brakes brake in | | Value Rating:Overall Rating: |

| | Weaknesses: | lever design | | Similar Products Used: | V-Brakes, Hayes, Grimeca quad-piston | | Bike Setup: | Specialized FSR, Z1's, front disc, freeride setup | | Bottom Line: | very good brake for slower technical stuff, cause the modulation is just great, but you feel the lack of power when braking at high speeds
not to mention that i have to ride with two fingers on the brake at all times (it just won't stop with one finger),resulting sore hands after 10 min.
If you're on a budget get this brake, you won't be sorry for this price. But if you are into dh, get hayes or the Grimeca quad-pistons (those kick ass and look better)

$110.00 | | Purchased At: | Supergo | | Strengths: | I just built up my first wheel (grimeca hubs, d/b dt spokes, and a x-317 rim) today. This brake rocks( from someone with no disc experience, but passionatly hates rim brakes)!!! Super easy to set up awesome lever feel. More than enough power for me (140lbs) without any real break-in. | | Weaknesses: | None thus far. Oh yes ah the instructions; like real ones are more or less absent. | | Similar Products Used: | LX, assorted cheapy V's | | Bottom Line: | For $110, definitely leaps and bounds beyond V's. I Love It | | Value Rating:Overall Rating: |

Well after about a hour of installation they both leaked while still in the bike stand. I made the immediate switch to Hayes. Everything is all good. | | Value Rating:Overall Rating: |

Date Reviewed: July 18, 2000 | | Favoriate Trail: | Star Wars Trail | | Duration Product Used: | Less than 1 month | | Strengths: | Super easy to install, setup, and bleed. Jury is still out on pad change outs though. Powerful enough to stop my bike, but without the power to throw me over the handlebars. Very progressive modulation. | | Weaknesses: | Limited technical information, user manual is a little rough to read. If you need super stoppers with serious stopping power, look somewhere else. I have not been able to lock up the front wheel as of yet, but then again I have not put the miles on them to properly break them in. I will update this review again in a few months. | | Similar Products Used: | Magura HS 33 | | Bike Setup: | XTR Drivetrain, Marzocchi Z2 BAM, Race Face SyStem, King Headset, XT Rear brake with Sram 9.0 Lever (Pulls more cable!!!) | | Bottom Line: | While these brakes work great out of the box I would like to get a few more miles on them before I stroke them too hard. For the price they cannot be beat. $160.00 at Price Point. For now the feel at the lever is incredible and I do not worry about pulling too hard and being thrown over the bars. These work great for cross country applications, but you downhillers may want something with more of a bite. I will update this review in a few months, so be sure to check back periodically. | | Value Rating:Overall Rating: |

Date Reviewed: July 3, 2000 | | Favoriate Trail: | One's w/ big drops,rocksrootz!! | | Duration Product Used: | 3 months | | Strengths: | Excellent modulation. Their not too sharp, but give strong braking power. Plus the plastic coating around brake hose is a definite plus. Lever action is the smoothest. and oh b4 i forget, the price. i got mine for $175 from SUPERGo. These brakes are the cheapest in price on the market and work just as well as the Hopes, hayes and Magura's | | Weaknesses: | No real weaknesses. At least not yet(knock on wood!!) | | Similar Products Used: | Hayes, and Magura | | Bike Setup: | Grimeca front brake only. Getting the rear soon. GT XCR 3000, Race Face North SHore crank, SYStem, Easton Bars, Mammoth Rims, Drivetrain, XTR Baby all the way!!! | | Bottom Line: | These brakes work really well. Their modulation works really well. Their not dead on sharp like hayes or Magura, you have better control over the sharpness of the brakes. My only problem is that i hope they hold up. Oh and they look good too!!! When i bough mine i didn't know that they came in colors. After my purchase i saw them in red. I think later on they'll make them in more colors. Bottom line, they look good and work good what else could you ask 4!!! oh and | | Value Rating:Overall Rating: |

over all a kickass break for a damm good price too
for sure 5 chilis for the value and about 4 for the overall, | | Value Rating:Overall Rating: |

Date Reviewed: June 28, 2000 | | Favoriate Trail: | Debengeni falls DH | | Duration Product Used: | 3 months | | Strengths: | Braided steel hose linings, and made by a very respectable Italian company. Open system, and they also make the Shimano brake system. Mine are actually labelled XSIV - Supposed to spell "excessive" | | Weaknesses: | Difficult to change length of hoses if you need to. Lever tend to clip out of master cylider of you hit them hard from behind. (My hand slipped of the handlebar and sprained my thumb) | | Similar Products Used: | Hayes | | Bike Setup: | KHS Dominatrax with Marzocchi Monster T forks, XSIV hubs, etc.. | | Bottom Line: | So far so good. Stops well, but does not seem to be quite as powerful as the Hayes on my TREK VRX though. Modulation is good, and they cost half the price of Shimano but are made in the same fatory. The fittings on the hoses are a pain, and system similar to Hayes would bave been better.
Otherwise they seem fine - I need to ride them a bit more though. For the price and function I regard them as a safe choice that should not dissapoint. | | Value Rating:Overall Rating: |
