Reduced Braking Performance: If your vehicle takes longer to stop or the brakes feel less responsive, it could mean the brake pads are too thin to function effectively. Vibration or Pulsation: A vibrating brake pedal or steering wheel during braking may indicate uneven wear or warping, signaling the need for replacement. Warning Light: Many modern vehicles have a brake pad wear indicator light on the dashboard. If this light turns on, it’s time to check and likely replace your brake pads. Visual Inspection: If the brake pad thickness is less than 1/4 inch (approximately 3-4 mm), it’s time for a replacement to ensure optimal braking performance
