What are the main functions of a disc brake lock?

1. Preventing Vehicle Movement: A disc brake lock inserts a locking tongue into a hole in the brake disc, directly preventing the front wheel from rotating, effectively locking the vehicle and preventing theft.
2. Improving Braking Safety: When parked, the locking device also enhances brake retention, preventing the vehicle from sliding on slopes or bumpy roads.
3. Visual Deterrence: The bright color and conspicuous structure immediately indicate the lock to potential thieves, acting as a psychological deterrent.
4. High Compatibility: Compatible with a variety of disc brake systems, users simply select the appropriate size for their vehicle model for quick installation.

Why are my disc brakes locking up?

1. Rusted or Stuck Piston: After prolonged disuse or water ingress, the piston inside the brake caliper can rust, resulting in a non-returning brake and a locking phenomenon.
2. Degraded Seal: Degraded, swollen, or deformed rectangular rubber seals can prevent the piston from returning smoothly, also causing lockup. 3. Damp brake fluid or high water content: Water mixed with brake fluid creates air lock at high temperatures, affecting the normal movement of the piston.
4. Rust and adhesion of brake discs or brake pads: After rain or long-term parking, the surface of the brake discs and brake pads rusts, increasing friction abnormally and making the vehicle prone to locking.
