The previous brakes worked but were very average especially the back brake. I bought the 3-pin version in black, and the product arrived about a week or so later, as described in the listing. The product consists of a box containing a pair of rotors, the front and back callipers, the left and right levers and a set of adaptors to suit different kinds of mounts on the bike along with some screws, olives and other parts to install them, i.e. as shown in the picture. The box also came with a small leaflet indicating that the supplier had a video showing how to attach them. I have never fitted hydraulic brakes before, so I mailed the company. Their representative, Joe, was very helpful. He sent me a video using WhatsApp and answered my questions. The video was very useful, and I found a couple of others on YouTube. Having Joe around to answer any questions I had made the task both easier and a pleasure. He was very helpful. In my case, my bike has an IS mounting for the back calliper and a post mount on the front. The relevant adaptors were in the kit. So I simply fitted the parts and then attached the callipers to the levers. Attaching the hose to the lever took some care, but the video supplied covered that in detail. The only difficulty I had was that the product is supplied with male Julet plugs, and my bike was expecting female ones. So, I took the old level cables and cut, soldered and crimped the connections onto the new levers. I am glad I made this change because these brakes are a massive improvement from what I had. They have a very positive braking action, probably because of the four pistons. The adjustment was a breeze. It is a very good product. Having used them, I'd hate to go back to mechanical ones. ## Features - Powerful Braking Force: Experience fast braking with 4 pistons in each brake caliper, ensuring powerful braking performance for every ride. It comes pre-bled with environmentally friendly mineral oil, ready for use without the need for bleeding. - Designed for E-bikes: This brake system come with a brake automatic power-off sensor and are compatible with 2-pin/3-pin connectors.
