Four-piston E- bike bilateral hydraulic disc brakes, compared with the same level of double-piston brakes, the braking force is increased by 25%, and the wear resistance is increased by 150%. Whether you are climbing/off-road/jungle/urban leisure riding, it can easily cope with it; The 22.2mm brake handle caliber design is suitable for 99% of the bicycle handlebars on the market. The brake pads are upgraded with resin brake pads, which will not damage the discs. The normal size makes replacement more worry-free.

The Hydraulic lines weren’t connected and there were no instructions. You need put in your AD that you have to connect these up yourself. Normally hydraulic brakes are pre-connected.These have amazing stopping power even on 180mm/160mm rotors. 1 star offbecause there are no instructions at all and you have to connect the brakelevel to the brake hydraulic cable.Here’s what you need to do:1) put the big cone cap on the brake cable2) put the long screw threaded nut on the brake cable, nut away from the end of the cable3) put the brass compression nut on the brake cable (doesn’t matter which way around)all 3 of those must go past the little cap nut on the brake cable.4) unscrew and discard the bolt on the brake lever5) unscrew and discard the little cap nut on the brake cableTry to keep the brake cable end upright and above the actual brake so no fluid leaks6) push the brake cable into the brake lever hole.7) push the compression nut into the brake level hole.8) push and screw in the long threaded nut – use a spanner to get it tight to compress the brass compression nut and grip the cable into place.Should all be good and working, if it leaks it means you’ve messed up the compression nut somehow. If you damage the compression nut – you’ll have to buy a new nut.

Hoses were just about able to reach. Will be replacing them with longer ones. But the braking power and feel is incredible!
