Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a ceramic wear-resistant brake pad. Background Art

[0002] Ceramic brake pads are a type of brake pad, including mineral fiber, aramid fiber and ceramic fiber. Ceramic brake pads are cleaner and quieter, and provide excellent braking performance.

[0003] For example, the patent application "CN208651494U" describes a wear-resistant ceramic brake pad. While the noise-reduction holes and high-temperature sound-absorbing cotton used in the ceramic pad during braking operations can disperse noise onto the high-temperature sound-absorbing cotton within the noise-reduction grooves, further reducing noise transmission, the noise-reduction grooves reduce the strength of the ceramic pad, posing a risk of breakage. Furthermore, the anti-slip grooves further reduce the pad's strength, shortening the pad's service life. Utility Model Content
