Zoom H876E 2-PIN/3-PIN 4-Pistons E-Bike Electric Power-Off Hydraulic Brake Set with 180mm Rotors, Pre-Bled Hydraulic Disc Brake Caliper Lever for eBike (Included Mounting Adapter)

The mechanical brakes on my cheap Ebike weren't very good. I added these and the bike feels a lot safer. The 2 finger lever is very comfortable. Great brakes! Customer service was very helpful also.

If you’re coming from mechanical disc brakes these will be a huge improvement. Installation was pretty straightforward. Braking on my 29” e-bike went from barely stopping to one finger braking. I haven’t had any leaks or issues. The red anodized paint look is a great accent. The kit comes with everything needed for Bafang mid-drive, even two short 3 pin brake lever / motor shut off adapter wires. Using a good pair of cable cutters I was able shorten hose to proper length. They are pretty compact in size, making installation in tight areas easy. I bought a bleed kit, but never used it. Brakes felt highly responsive the moment I pulled the lever. The hardest part of the installation was tapping in the hose compression fitting. They make a tool for this, but a few taps with a small hammer worked fine. The build quality is great. But my set did come with an insignificant scratch on one caliper. You only see it if you’re looking for it. I wish I’d known how well four piston 180 mm hydraulic brakes stopped before wasting money on ceramic brake pads for my old mechanical 160 mm brakes. If you’re undecided on a new set of brakes, I highly recommend you give these ZOOM HB-876E four piston hydraulic brakes a try. UPDATE: One month later and ZOOM brakes are still performing perfectly. They work great on my 70 pound e-bike and 230 pound rider. I offe hear complaints from Shimano brake users that Chinese brake products are garbage. That’s not been my experience at all. These ZOOM brakes are one of the best investments I could have made. ⭐️⭐️⭐️⭐️⭐️

These brakes were awkward to connect to bike took me about an hour all works well only thing is the electric sensors did not work

I bought this product to replace the mechanical brakes on my E-Bike. 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.

Really great product and easy installation hi quality
