When it comes to replacing your Eagle brakes, the rule of thumb is: 'It's better do it sooner than later.' At the first indication of worn-out brakes, take the time to inspect and replace your Eagle brake components. The simple act may save your life, and at the very least, prevent major engine damage. Your Eagle brakes are well-designed works of engineering. Just consider the physics that are involved with the simple act of braking: you depress your brake pedal, and then your car transmits the force from your foot to its brakes through a fluid. That force is applied through leverage and hydraulic force multiplication. The brakes transmit the force to the tires using friction, and the tires transmit that force to the road using friction. Luckily, Eagle brakes usually give plenty of warnings before they fail. The brake pedal might be 'hard,' or resistant to pressure. You might hear squealing at low speeds that are emitted from your break wear sensors. You can check for brake pad wear by viewing the pads from outside the front tire. On most cars, you can look through the openings on the outside of the wheel/rim assembly to see the pads. If the pad depth is less than ? inch, then replace the brake pad soon. If it's less than 1/8 inch, you are risking damage to the rotor and replace those pads with genuine Eagle brake pads immediately.
