The Sur - Ron Hydraulic Brake Lever Cylinder Pump Assembly is a top - notch fit for Light Bee X models. It's available separately for the front or rear brakes. This assembly only includes the lever pump assembly, offering a plug - and - play electric brake cut feature. Please note that it does not come with a caliper, fluid line, etc.

Using this SurRon brake cylinder pump assembly is easy. First, make sure your bike is turned off. If you're installing it on the front or rear, follow the corresponding bike's installation guide. Just plug in the electric brake cut as it's a plug - and - play design. When using, simply pull the brake lever like you normally would. For maintenance, regularly check for any signs of leakage. Keep it clean and dry. Also, don't forget that this product doesn't include a caliper or fluid line, so you'll need to take care of those separately. If you have any issues, consult a professional bike mechanic.
