Will a Disc Brake Lock damage my brake discs or braking system?

Will normal locking scratch the brake discs?

Most Disc Brake Locks are made of hardened steel or stainless steel and are designed to contact the brake disc surface to prevent thieves from rotating the brake calipers. Generally, the hardness of this material matches the brake disc material and will not cause serious scratches or structural damage.

Potential effects of long-term locking

While normal locking won't cause immediate damage, if the motorcycle is left unmoved for extended periods (such as weeks or months), the continuous friction between the lock and the brake disc may have the following effects:

Minor scratches:

Due to the slight difference in hardness between the lock material and the brake disc material, prolonged contact may leave minor scratches visible to the naked eye. It's important to note that these scratches are usually surface-level and do not affect braking performance.

Local wear:

Improper use of the lock (such as excessive contact area between the lock body and the brake disc) may lead to accelerated localized wear.

Risk of rust:

If the lock is of poor quality or exposed to a humid environment for a long time, it may rust and stick to the brake disc, making removal difficult.
