How to repair a loose mechanical disc brake
It can be fun and convenient to own an electric scooter, but riders should also keep in mind some basic adjustments and repairs to maintain their e-scooter. To begin with, you must know how to adjust the brakes on a scooter.
Make sure you are on an elevated position before adjusting your brakes, so you can freely turn the wheels and check their grip.
If the brake is too tight, use the wrench to loosen the screws on the calliper, and slightly send back the brake cable to shorten the exposed length, then tighten the screws. If the brake is too loose, loosen the screws, and slightly pull out the brake cable to lengthen the exposed length, then tighten the screws.
If you hear a scraping noise, either your brakes are too loose or too tight, or your brake pads are touching your brake disc.
