Mechanical disc brakes
A cable operates the brake at the wheel. Cable condition, adjustment, pad wear and disc alignment all matter. Follow the maintenance instructions for the exact assembly.
Hydraulic disc brakes
A hydraulic system uses fluid pressure to operate the brake. It has its own inspection and service requirements. The G3 Pro (coming soon) is one model to compare when this hardware matters to you.
Electronic braking
Electronic braking can be part of a scooter's combined system. Check the manufacturer's description of how it works with the physical brakes rather than treating it as a replacement.
When replacing parts
Match the pads, caliper, disc and mounting dimensions. Similar-looking brake parts may not fit. Check operation at low speed after service and stop riding if braking is unreliable.
