The document discusses the history and components of anti-lock braking systems (ABS), explaining that ABS was first developed in 1929 and prevents wheel lockup under heavy braking on slippery surfaces through hydraulic or electronic control units that monitor wheel speed. It provides information on how ABS works compared to regular braking systems without ABS and the advantages of ABS in improving vehicle safety and control during braking.
