3) Braking Force – As the brake pads wear out, there is a gradual loss of braking force. For those who drive on a regular basis, it is easier to detect and diagnose such drop in braking efficiency.
2) Dashboard Warning Lights – Several modern automobiles are equipped with sensors that detect worn out brake pads. The system throws out warnings in the form of lights or icons or on-screen messages.
1) Brake Pedal – Mild vibrations on the brake pedal during braking point towards worn out brake pads. Change in brake pedal play and feel means that the braking system needs attention.
