Car grinding noise when braking is caused by: worn brake pads with metal backing plate contacting the rotor (most common), debris lodged between pad and rotor, morning surface rust (disappears after 2–3 stops — normal), or a seized caliper. ABS activation during hard braking also creates grinding — this is normal. Use the ‘When does grinding happen’ matrix: every stop means pads, mornings only means rust, only in turns means bearing.
