Thanks for sharing your experience! I'm sold on juin tech already. I think you forgot to mention that the JT GT-F are 4 pistons per caliper, meaning there is a bigger contact surface when braking. I actually might opt for the older F1's, since two more pistons mean more possiblities of pistons seizing, which is the most common issue in all hydraulic calipers I think, and I want to have a very resilient rig in the end. Cheers!
Hey you are welcome, yes you are right 4 pistons indeed, as far as failures I have not heard of anyone having seized pistons on these guys apart from some guy using them in sub zero temps if I remember correctly, Let me know how you like the F1's if you do go that route.
I love that the juintech comes in different colors. I fixed up an mtb and converted it into a commuter installed juintech f1 on it. Since I stripped the paint and made it glossy I pared it with the silver juintech.
TRP HY/RD kept leaking on me. Got 2 warranty pairs from TRP, also leaked…. Used on my gravel bike. Fitted a pair of Juintechs, no issues. Closed system.
Using the TRPs with the matching rotors does make a difference in performance. Also thinking about trying the Juins for comparison though. Thanks for your opinion and the informative video.
I tried both of these...Juintech is fine until you do long descents so be wary of it...it loses it's braking power, TRP on the other hand provides more braking assurance on long descents (tried this so many times). Also, Juintech seals break off in (more or less) 2 years of use and their customer service and parts are nowhere to be found! They are also as expensive as the TRPs..so basically, you throw them away if they become faulty. As for TRP, I had one on my gravel bike for around 5 years now and just bled it a week ago for the first time. NO ISSUES for as long as you follow their customer support service instructions. Just use metal brake pads if you want more power and tweak the system if you opt for auto pad adjustment setup or a closed setup (non-adjusting). Like I said, braking power is subjective...if you want an eye-popping brakes, just go ahead and buy a full hydro system...modulation is also subjective, so one may choose over the other...BUT I PREFER bike parts that lasts long....as for 4 pistons, yeah they do stop you faster BUT as for how much faster? My tests only showed 1 meter of more braking power at same speed.. IMHO, SUDDEN braking isn't the solution...braking ahead does..
I guess we have had very different experiences with the Juintech, brake fade has not been an issue (at least not more than any brakes running 160mm rotors) in the last year I have been using them on a rig that is frequently fully loaded, as for parts, there are places where you can get the seals for them if need be, no need to throw them away (if you do, ship them to me instead ill pay for shipping). They also share the same parts as the Yokozuna brakes if you are in the states. Modulation and bite was also much better than the trps in my experience. They are also 80$ less than the TRPs. Like you said feel is subjective but for me the Juintech GTs are better brakes by a long margin.
Hey thanks for the review i just bought a kit of gt f myself cant Wait to try Them . I was looking for a seal kit preventively but did not find any ! Please Let me know where to get it if you Do thanks ! Cheers
@@VinceLefort Hey cheers, I know they always have them here : www.edgesportsuk.com/store/juin-tech/juin-tech-gt-f-gt-p-pistons-and-seals.html and they ship world wide.
so much love n hate...love what you have...enjoy what you got. i have the TRP HY/ROAD HD-C711 on rear loving it. front is full hydraulic shimano rs505....SUPER COMBO on my gravel!
Interesting review, thanks for making it. I have the TRP HYD/RD supplied as OE on my Triban RC520. I’ve ridden over 3000 miles, 80% on roads, and they have performed faultlessly. Having said that, your comments have confirmed my decision to fit the Juintech on my new gravel build. This decision based on aesthetics and price.
Just an FYI concerning your current TRP Brakes. There are replacement arms for the TRP brakes that shorten the cable pull and eliminate the issues with the hack methods often found on the Internet. JJBP Short Pull Conversion Brake Arm Set for TRP HY/RD The cable pull is often one of the issues with the TRP brakes.
The GT I had permanently lost it's braking capability after 100 miles on my cargo ebike, which I frequently load with 500+ lbs. When I got home I ordered the HY/RDs for $150, they were much cheaper than the GTs and they're still working like new with no maintenance after 2000 miles. I find that I'm far less on the brakes with the HY/RD since they have a shorter stopping distance over 15mph, which is a must for city riding or generally hilly terrain. The GTs have a sudden jolt in clamping force that eases over time to the point where you feel like you might not have enough power within 5 seconds of holding. I suspect that they'll feel a lot better for those who carry and weigh significantly less.
Yes they are definitely not for cargo ebikes with the load you are carrying, you will get brake fade as they are not a reservoir type brake and will overheat with such heavy loads, for your application a reservoir type brake is better. That being said the GTs come with resin pads but for your application semi metallic or metallic pads would have been much better, your original pads were probably glazed after a few rides.
@@MaverickTube I don't have overheating problems with 203mm rotors regardless of the pad or brake, it was a different issue I don't fully understand. The stock pads on both seem to have normal levels of wear similar to my mountain bike, but I only used them for a hundred miles each. I swapped the stock with metallic pads and they still work perfectly.
Another problem with trp hy/rd is piston section bleed plug grub screw is the same hex size and too close to pad screw resulting in higher probability of turning the wrong screw especially when not being able to see them in awkward positions.
The way the Juintech calliper takes the cable is on the side where else the TRP is right in the middle of the brake pads. This is an important thing to check for because there are bikes with the cable routing that causes an S routing after exiting the frame, going into the callipers. TRP is huge though.
Nice comparison! I've been wanting to try juin techs for a while now. My problem with the hyrd's is the cable pull required, one of the mods to shorten the pull involves a hacksaw lol

My VERY difficult issue is choosing between cable actuated hydraulic caliper (hybrid) design, or a full, 4 piston hydraulic set. Budget is small, the Juin-Tech is the M1, vs a Zoom HB-876E 4 piston set with lines, levers, 180mm rotors. Technically the Zoom set is all low end stuff, but is a 4 piston, full hydraulic set going to out perform a slightly better quality "caliper-only" swap out with 2 piston cable pull calipers. I would expect the zoom to outperform, but to be potentially less durable than the Juin-Tech setup. Would love to hear your thoughts?
@Maverick Enjoyed your narration, clear and to the point. I wish someone would do a well controlled test with various rotors. Then perhaps brake pads. Is there a brake lever that is best choice with the cable actuated hydraulic disk brakes ?
Thanks Paul ! Maybe one day I'll have the chance to do a side by side test but I can tell you without a doubt that the GT's will perform better, the 4 pistons alone sets them apart.
Hi there. I'm trying to move on from rim brakes to disc brakes. I'm not a bike packer or commuter. I'm racer( not much due the pandemic) but we still do speedy club/ group rides. Like I mentioned before, I'm trying to move from rim to disc brakes. I have ridden a hydraulic disc brake road bike, but it was borrowed from a friend. On the other side hydraulic disc brakes sets are expensive and hard to find. I thought building a road bike with these ( mechanical )to start with, so I can use my shifters and afterwards replace them with a full hydraulic set. The road bike( Scott Foil ) I've ridden was for 1 mouth in my possession. I've heard that disc brakes locking up or these mechanical ones with piston getting stuck. I just want to build something that I can rely on without worrying about that so I can concentrate on my ride. What would you recommend me? Thanks in advance
Honestly I have had them for about a year now (the juintech) and I have had to do no maintenance on them, as far as locking up these are hydraulic so not the same set of problems as your typical mechanical set. In terms of performance I think you would be hard pressed to find any meaningful difference between the juintech and full hydraulic breaks, now in terms of cost the juintechs are not cheap (around 300$) but cheaper than changing both shifters and with parts availability for big brands like shimano and sram being almost non existent I think it is even more of a solid choice.
@@MaverickTube Thanks man. You convinced me. Lol. I think I'll go for this one. after all $300 is way cheaper than $1.790,00 or 2.000, and I can keep my shifters
@Aldrin Clementina Keep in mind also that to get the best performance out of the juintech you will want to invest in quality compression-less housing like Yokozuna reaction or the Jagwire Pro. These will add to your total.
A little late, but the Juintech R1/F1 single piston calipers are about half the price of the GTs, and for road cycling (not bikepacking) they provide more than enough braking capability. I recently replaced my TRP HY/RD calipers with the Juintech R1s and in my opinion the Juintechs are WAY better. More power, better modulation, and most importantly I can't bottom out my brake lever against the handlebar like I could with the TRPs. Well, maybe I can, but I'd be flying over the handlebars by then!
Can someone help me here? I bought a gravel bike and the mechanical disc brakes that came with it are awful. The rear one failed and I found the exact same one online and replaced it. Now that same brake caliper is “sticking” to the rotor and won’t come off when I release the brake levers. At this point I want to upgrade. My mechanical disc brakes are “flat mount” NOT post mount. Will the TRP’s work? Thanks!
I use the F1s on my road bike and I do long descents all the time with little to no issue. They do overheat slightly faster than Ultegra hydraulic brakes but not by that much tbh
i think that having the cable as a method of power transfer takes away all of the advantages of the hydraulic system. If you understand the capstan equation. you know that these brakes are completely pointless. Essentialy in cable pull systems the drag is primarily caused by the bends the cable undergoes, the more the cable bends the friction required to overcome the force required to move the cable increases exponentially. this friction works both ways, basically this means that the brakes will feel like cable pull brakes in how vauge they are. Hydraulic systems do away with this and move the power no matter what direction the hose takes as long as it gets to its destination. the only slop in the system is the stretch of the hydraulic hose, and the compresibility of the brake pads. The friction is not created in where the cable meets the caliper or where the cable meets the brake lever. Making this entire system pointless. this has the downsides of both hydraulic and cable pull at the same time.
The self adjustment was actually the main reason I picked up a set of the TRP ones. I lived at the top of a big hill and got irritated by constantly having to mess with my old calipers
I would have to disagree. The point of this product is to provide an upgrade in braking power without the hassle of rerouting hydraulic brake lines. The main benefit is you can apply the same force that you would on a pure cable system and multiply the force using pascals principle. It is not ideal, and shouldn't be used for something like a car where the load and speed requires more friction.
Now, why not compare Juin Tech 2 piston against TRP Hy/Rd (2-piston)?? THIS COMPARISON IS UNFAIR...it's like comparing a twin piston Shimano MTB brake against a quad piston SRAM MTB brake.. We all know that a wider braking surface will provide better traction...it's not "entirely" about the brands that we're comparing here. You should modify such reviews since it's not on equal ground. I will tell you though, by a slim chance, Jiun tech QUAD piston had an edge over TRP hy/rd...I tried it and , there isn't much difference...The only time Juin Tech 4-piston was better, when I tested it on FLAT roads... also Juin Tech builds up heat like a bitch! That's scary on long descents - like 20km long descents. Gaskets melted; It was a waste of money. Also the Juintech GT-F doesn't have a vent hole to compensate for pressure changes that's why it loses braking power on extreme conditions. Simply put, you have not tested it long enough to make a comparison. Or, you did a shitty install on your TRP's that's why it wasn't working properly. The older Juin Tech 2-piston was even shittier when it comes to bite (actually it had almost 0 bite power); also pistons were already stuck from out of the box...it was no match for the TRP Hy/Rd...good that JuinTech discontinued their 2-pistons! they were endangering so many cyclists with that junk.
1- this is not about comparing the two brakes as apples to apples but rather taking a look at two most popular options of hybrid brakes and talking about my experience, yes 4 pistons has an advantage over 2 pistons. this is not a scientific review neither does it claim to be. 2- I don't live in a high alpine area so I cannot talk about the need for vent holes to deal with pressure changes, where I live it is mostly short punchy climbs and descents, no 20 km descents here. For your specific use, the Hy/rd might very well be the best option. 3- The juintech R1 are still being sold, there is also a large pool of cyclist loving these brakes and you disliking them does not make them junk, in the same way that me saying that for my use the juintech are better does not mean the Hy/rd are bad brakes. 4- Now when it comes to the way I installed the brakes, that is a bit of a jump isnt it? you disagree with me, that's cool, maybe next time be a bit more nuanced in your critic ? we are not comparing first born child here. Have a good one.

Good review but one spec. that you should point out is if the pistons are dual actuated. This is what I think is superior w/ TRP's designs.
Yes indeed, 4 pistons make a big difference.
