Has these for 2 years. Great stopping power ### ⭐⭐⭐⭐⭐ Excellent upgrade for an ebike *by on Reviewed in the United States 16 February 2024* Own a Cyrusher XF 800 Ebike with 4500 miles on it. The existing brakes started to get air in them frequently and I had to bleed system more than I would like to. Had more than a few brake pad changes and they performed just ok after install.The original brakes were made by Zoom and are single piston calipers. I decided to upgrade to dual piston calipers for better brake performance. These are also made by Zoom and purchased two pin in color Red. Must admit they look sharp on the bike.Install was fairly easy. Just remember to add the little hose barbs with conical Brass ends inside the hose. As others before me have stated use a screw in motion to seat the hose barb all the way down inside tube.I wish they would give three of the brass hose collars and not two as inevitably one gets ruined or lost in the process. To be clear if you cut the hose for a custom fit you need to use tubing cutters and not scissors or Dykes. A tubing cutter will leave a nice clean cut so the collar will fit over easy.In my case no bleeding was necessary and there is little brake lever travel before brakes are on solid. On this particular bike they chose to mess up the orientation of the left right lever . It should be right lever equals right rear so that's what I changed it to.Pistons appear to be small in comparison with the other big name brake companies like Shimano and Magura but at this price point you do get what you pay for.its too cold in the Northeast now ( Feb 2024) to test much but a brief run revealed better stopping power even before brake in of pads. I will upgrade review as i get miles on the bike.Right now I think its worth buying and upgrading your brakes using this kit.Update -Cool Meng sent me some Olive rings and hose barbs. ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in Canada 21 April 2025* Good ## Frequently Bought Together - CooMeng Zoom HB876E 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) - Zoom 4-Pistons Replacement Pads Semi-Metallic Brake Pads Compatible with Zoom HB876E, XTR XT Surron SLX Deore Saint - CHUMXINY Brake Bleed Kit for Shimano, TEKTRO, TRP Hydraulic Disc Brakes.
