Upgraded 4-Pistons E-Bike Electric Power-Off Hydraulic Brake Set 1 Pair

About This Upgraded Brake Set
Attention: You should know before ordering!
1) The upgraded 4-piston brake system fits most ebikes with brake wire quick-release plugs in the market and as for BeeCool models, it fits all our ebike models but please pay attention to the red 2-pin plug's size. Some old versions of our ebikes have a plug diameter of 7mm while the plug diameter on our latest ebikes is 8mm. Therefore, if the plug diameter on your bike is 8mm, you don't need to do any modification but just use the upgrade brakes here perfectly on your BeeCool Bikes. However, if the plug diameter is 7mm on your BeeCool ebike, you need to replace the brake sensor wires on this upgrade brakes with the sensor wires from the original bike. 

Things you should know before replacing the sensor wire:

Brake pads will come with the brakes and the pads offered are metal one. If you need pads for future replacement, you can refer to the pad size below:

2) We would only suggest you buy this upgraded brake system if you have enough skills and tools to operate it as shown in the tutorial video or if you are available to nearby bike shops that offer brake assembly service.
