Noisy brakes can also be a telling sign that your ebike is in need of a check-up, repair, or even possibly needing replacement components. Excessive noise from your hydraulic disc brakes may signal that there is an issue with the rotor and brake pads. More specifically, that the brake pads and rotor have been contaminated from excessive lubrication or oil, causing the noise.
Before determining if that is the case, use rubbing alcohol and a clean, dry rag to wipe down your rotors. An intentional cleaning generally can make the excessive noise go away.
