A rotating disc component in disc brake systems that converts kinetic energy into thermal energy through friction to slow or stop vehicle motion.
Commonly used trade names and technical identifiers for Brake Disc/Rotor.
This component is used in the following industrial products
A mechanical or electromechanical device that stops or holds an indexing mechanism in a fixed position.
A mechanical or electromechanical device within a positioning system that controls deceleration, stops movement, or holds position.

Brake discs typically last 50,000-70,000 miles but require replacement when worn beyond minimum thickness specifications, show severe scoring, cracking, or excessive runout. Always follow manufacturer recommendations and inspect during brake pad changes.
Disc warping results from uneven heat distribution during aggressive braking, improper torque during installation, material inconsistencies, or rapid cooling (like driving through water when discs are hot). Proper bedding-in procedures and avoiding extreme thermal stress can prevent warping.
Solid discs are single-piece designs for lighter vehicles; ventilated discs have internal vanes between friction surfaces to create airflow, significantly improving heat dissipation for heavier vehicles or performance applications.
