XT-8 Cable Actuated Road Bicycle Hydraulic Disc Brakes Caliper Set, Line Pulling Extra Powerful Hybrid Brakes For Road bikes(with 2Pcs 160mm Rotors)

The Good: -Comes with brake spacers (very useful for transport with wheels off) -Includes lots of hardware (not necessarily everything you’ll need but maybe) -Better performance than single pistons -Doesn’t require hydraulic tubing setup -Comes with brake pads -Comes with rotors -High quality CNC components The OK: -Included adaptor won’t work for many bikes (but they did include one) The Bad: -Nothing If you’re looking to upgrade your brakes to something generally less noisy and with more stopping power but don’t want to upgrade your handles hybrid brakes are a great option. This set is really well-made being mostly CNC components and even comes with the rotors/mounting hardware. Provided you’re trying to install these on a bike with a hole distance other than 34mm you will need an adaptor. When you manage to get them on your bike, you’ll be rewarded with exceptional stopping power compared to a single piston model. They include the brake pads and a set of brake pad spacers to ensure you can transport the bike without wheels and not worry about having to spread the pistons. If you’re in the market for a quick and easy upgrade to a single piston cable disc brake this set’s really worth considering. They’re quality construction but just make sure to measure your mounting space so you can have the right adaptor ready if you need one.

If you are buying them brakes for the reasons I did you will be happy. My group set is SRAM with double tap shifters...and cable brakes. I would have had to spend $500+ for a full group set IF I wanted full hydro disc brakes. My cable brakes just didn't offer the modulation or pure stopping power I desired. Install of these brakes is simple and easy. Please keep in mind I am a bike mechanic certified by Trek. On my 1st ride they worked decent as they were not bedded in yet. I used different rotors than what the brakes came with, they are garbage. I paired them with 160mm Avid rotors. After about 5 rides, they are starting to make a difference. The adjustments I have made have given them good power. They are not hydo brakes good, but they are better than stock cable brakes. Keep the following in mind if you're looking to buy a pair. 1- Stock rotors are cheap and don't work well. Plan to buy some name brand (SRAM, Shamino, TRP) rotors to unlock the brakes potential. 2- Be certain that you clean the rotors and pads every so often until they start to stop really well. Use 91% rubbing alcohol on a rag, and wipe the brake surface of the rotors. Allow it to dry a few minutes before you ride. 3- Brake cables DO NOT transfer 100% to the brakes. I suggest you use new inner brake cables or you will be adjusting the cables often until it feels right. With a fresh cable, you just run it from the lever to the caliper, add a bit of tension with some pliers and tighten the holding bolt. Then clip the cable and put a cable end on it to prevent fraying. I have given the brakes 3 stars for now, as I feel in time the power will increase as the pads and rotors become more "bedded in". For now power is a bit better than cable brakes, but modulation is 100 times better. Hope this helps you decide if you want to purchase or not. If anything sounds Greek to you, have a bike mechanic/shop Install them.

Where do I start? I've got a Rans Stratus XP, which is a long wheelbase recumbent bike that had the provisions to mount disc brakes on both the fork and rear stay as well as both hubs. I had always wanted to put discs on it but what always stopped me was the "If it aint broke, don't fix it" paradigm. But I saw these pop up and figured what the heck. Heck is what I'm going to get into. For starters, they look to be pretty well made parts with decent machining and finish, packed in a nice box. Came with a set of 160mm rotors and one adapter to let you mount them on post mount equipped bikes. But I don't have a post mount, which is probably the most common mount on mountain bikes and the like. No, my nice old recumbent is ISO which back in the day stood for Industry Standard which is not nearly as common anymore. But they make adapters, right? So these calipers are what as known as flat mounts. That's a new type of mount that Shimano came up with because God forbid we cant get by with just two standards. Now we have 3. But they make adapters right? Yes they do and good luck finding one that lets you go from flat mount to ISO. I managed to find one here on Amazon for about 20 but I couldn't use it on the rear stay without either filing some of the bike frame away or modifying the adapter. But it did seem to fit the front fork. Unfortunately the 160mm discs supplied dont come close to being large enough to work on this setup. So I ordered a set of 180mm. Nope, too small as well. I measured 200MM but nobody makes a 200 unless is priced at 50 for a name brand part. But they do make a 203mm rotor so I figured in for a nickle... With lots of finagling I got the caliper and the adapter mount shimmed with washers so that the rotor sat center in the opening between the pads. But I couldnt get the wheel to go 360 without a bit of rubbing on maybe 3 out of all the raised bumps on the rotor. Remember I did measure it around 200mm. So I decided to go ahead and grind down the high points on the rotor maybe a MM or so and after putting it all back together I was able to get the wheel to spin freely. Whew. I went ahead and got a longer piece of cable housing and made a new cable to the brake lever and zip tied it all nice and neat. Seemed to brake well on the stand. Took it for a ride. Was expecting it to be much more powerful than the rim brake, but no. Maybe about the same stopping power, even considering the fact its hydraulic. I should have listened to myself in the first place, if it aint broke... I left the rim brake parts on the fork and will give this a month to see if it gets a bit better as the pads bed themselves to the rotor. If it starts making noise or just becomes too problematic, I'll take it off and swap cables back to the rim brakes. I dont think I'll mess with the rear brake, it's not worth the effort. Just to get the front working I spent 20 on a mount adapter and 11 on a rotor. I had the other parts already. My advices is that if you have similar flat mounts on your bike and need replacement calipers, you can try these, but I think that would not apply to most folks. I learned a lot and as my brother likes to tell me, it has "Hobby Value".

Wanted to improve the brakes on a Lectric XP 2.0 ebike without doing a full hydraulic setup - if for no other reason than to just re-use the pulls and existing cables to do it quickly. I did take off the front wheel and went up to a 180mm rotor size there, and these pulls are fine with that - caliper still in the right spot without so much as an extra washer. Stopping power isn't as good as full hydraulic, but that's baked into what you're getting. What it does give you is an EASY way to improve stopping power and do it with no more than a caliper swap-out. Now there's still cable stretch, but a lot more leverage than before. My XP stops in about 10 feet shorter distance from 25 MPH. I know because I measured before and after. These are good, and better than the Zoom hybrid hydraulics I'd been using for this purpose. I highly recommend these DY Island ones.

I put these on my road bike to replace the full mechanical setup that I was using. The difference is pretty good. I get better stopping power which helps me on long down hills and in emergency stopping situations. Modulation and stopping power is very consistent with the dual hydraulic piston system. Installing the calipers and rotors is pretty easy if you know a little about working on bikes. The only tools you will need is a set of metric Allen keys and you're good to go. The included titanium hardware is already prepped with thread locking compound, so there's no need to worry about that. Breaking in the new pads to the rotors is very important, and the more you break them in, the better the grip. Knowing this, I made sure to give plenty of break-in time before writing this review. Using the brakes now feels more solid and gives a lot more confidence. This is still a cable actuated system and cannot compare to the performance of a fully hydraulic system, but it is a good middle ground and and certainly an upgrade from fully mechanical calipers. For best results, install these with a good set of compressionless brake cable housings. Overall these calipers and rotors are a good upgrade and decent value considering the better performance you will get. Break them in properly, and you will have a noticeably better braking system for your bike.

Even after the break in period, they just won't stop my bike anywhere close to as well as my old full mechanicals. Not to mention that due to the shape, the front brake does not fit a 160mm. You need a slightly bigger rotor. Rotors that came with the brakes were not bad, but not as good as the ones I was already using, so I didn't bother using them. Maybe there is something that needs adjusting, but instructions for these are non existent.

This is a cable actuated disk brake system for a bicycle. It features hydraulic calipers that should be better than standard calipers. Included are the calipers, rotors and mounting hardware. Basically you remove the old caliper, disconnect the cable from the caliper then install the new calipers and connect the cable to it. Install should be failrly straightforward. I overlooked something though. This brake system is for a road bike. Apparantly it doen't fit my hybrid bike so install was not possible. Of course that is my mistake and I shouldn't fault the product for that. Quality of the parts looks fine. Shame that I was unable to test the braking performance.

These disc brakes are strong and sturdy. They seem to be good as the name brand ones. It comes with all the screws and calipers for easy installation. They look good and add more stopping power to your bike. The discs are vented or drilled and light weight. The calibers are strong and robust. These should be able to handle the abuse of trail riding.
