🔴 Squealing or Squeaking - High-pitched noise when braking indicates wear indicator contact 🔴 Grinding Noise - Metal-on-metal sound means pads are completely worn—stop driving immediately 🔴 Vibration or Pulsation - Steering wheel or brake pedal vibration indicates warped rotors 🔴 Pulling to One Side - Vehicle drifts left or right during braking suggests uneven brake wear 🔴 Soft or Spongy Pedal - Brake pedal feels soft or goes too far down indicates air in system or fluid leak 🔴 Extended Stopping Distance - Taking longer to stop than normal is dangerous and requires immediate attention 🔴 Brake Warning Light - Dashboard brake light illuminated indicates system problem 🔴 Burning Smell - Chemical odor after braking suggests overheated brakes or stuck caliper 🔴 Visible Wear - Less than 3mm pad thickness visible through wheel spokes 🔴 Rust or Corrosion - Excessive rust on rotors (common in EVs due to less frequent friction brake use) 🔴 Reduced Regenerative Braking - Inconsistent or weak regen braking feel 🔴 Electronic Parking Brake Error - EPB malfunction messages or failure to engage/release 🔴 Brake Fluid Leak - Fluid puddles under vehicle or low brake fluid warning
