Pleasantly surprised!
Great replacement for hydraulic brakes. No hassle to fit & pleasantly surprised by the quality. Everything you need comes in the box including bolts & brackets. Only minor niggle is that the front cable could have been a little longer while the rear cable was too long!! Easy to cut down the rear, not so easy to add a bit to the front!! All in all very good value for money 🙂

Cheap but functional disk brake kit
Bought these on a budget to replace hydraulic disk brakes on an old mountain bike. Limited instructions, but brakes were easy to fit and included bracket converters for my older fixings. Rear cable is a bit long and probably should be shortened. Initially I thought the brakes were poor, but they got better as the pads bedded in. I would say these mechanical brakes are fine for rough road or trail use, but for "real" mountain biking, you probably want some Shimano hydraulics.

These Are Better Than I Expected "READ UPDATE"
I have cable disc brakes on one of my other bikes and they work really well so now my hydraulic discs that where originally on this bike started playing up I decided to go cable, this brake set has all needed to do the job and for a really cheap price, I was expecting them to not be that good but was really surprised to find they are in fact really good. I had to get 180mm discs which are a little on the large size a least for the rear, but this bike has been converted to an e bike so the bigger discs are better as I brake from much higher speeds more often than I did when just rode pre e bike. I personally did not find them hard to fit, starting with the back first as I was concerned the disc being a larger diameter would hit the frame, it's close but not close enough to cause a problem, bolt on the caliper then happy with it was all fitting ok did all the cable routing, I did not use the levers which come with set and used the ones that came with the motor as they have sensors fitted to cut the motor when braking, once everything was cabled up it was just a case of adjusting everything. As it happened with the rear it all went ok, only one side of the brake moves unlike my hydraulic calipers where both sides moved, so getting these adjusted up just right took a little bit of fiddling but I managed to get it just right, no rubbing and a nice feel to the lever. On to the front which was what I thought was going to be the easiest but it proved to be a little more difficult than the rear as once all fitted up the disc pressed against the fixed pad even though the adjuster was screwed right in and the brake lever felt very sloppy, to rectify this I had to use spacers between the caliper and mount, it took a couple of try's with different sizes to get it just right but the brake still rubbed a bit, however the lever felt just right and the same as the rear so decided to leave it, I took it for a test run and the bike stopped just as well as it did with the hydraulic brakes and the rubbing stopped as well result. The only problems I found is the adjusters are plastic, you can either use your fingers or an Allen key to wind them in and out, be careful with the Allen key as I turned it in one too many times and spun the key in the hole so can not use that method now I just have to use my fingers which is not really a problem. The second problem was the length of the front cable, on my bike it was only just long enough I would have prefeed it to be longer if not just to make getting it in the caliper a bit easier. Overall I am quite impressed with what you get for the money and that they work really well, how long the pads last is another thing, time will tell on that one, Rujoi obviously recommend using their own branded pads so I looked them up and could not find any, but it does say these can use Shimano so will worry about that at a later date. UPDATE, I have been riding with these for around 600miles now and apart from some readjustment they have been working well, but then the other week I was just starting out on a ride pulled up the front brake and the lever moved right back to the grips and the brake did not operate, I took a look, could not see anything wrong, but pulling on the calipers lever it seemed the cable had slipped, but it looked to me the cable was the same length as when I fitted it, so I readjusted the cable, gave the lever a few hard pulls and it all seemed good, I again went out on quite a few rides with no problem, then today it happened again, this now concerned me, once again the cable had not slipped but there was Cleary something wrong and it needed sorting out, so I took the caliper apart and the problem was clear, the caliper lever has a hexagonal hole which fits over the pad pusher, because the lever is made of inferior metal it can slip round, so when the brake failed it was because the lever had slipped around one flat. This problem is of great concern as it can happen anytime, for me I was not hardly moving so I live to tell the tale but it could happen at the wrong time, so to me these are dangerous and I am replacing them with a more know brand.

So far, they've been a solid set of brakes. Easy to install and reliable to use. I'm impressed, given the cheap price.
