Electric Scooter Brakes Weak or Squeaking
Test, clean and adjust safely
Quick answer
Test both brakes before every ride. Clean an oily disc, take up slack in a cable brake with its barrel adjuster, and make sure each lever springs back. Hydraulic brakes, worn parts and anything you're unsure about go to a shop.

In plain English
Many scooters combine a disc or drum brake worked by a lever with an electronic brake in the motor, and some also have a foot brake on the rear fender. Weak brakes usually come from a stretched cable, worn pads or oil on the disc. Squeaks usually mean dirt or oil on the disc or pads.
