There are many safety features built into your Infiniti, and the braking system is the most important. If everything is working properly in your braking system, the car will stop when you step on the brake pedal. On the other hand, if there is something wrong with the brake pads, brake calipers or brake rotors, the car might not stop immediately - which will put you at risk for an accident. Servicing your brakes is something that should be a part of your routine maintenance. There are usually clear signs that something is wrong with your brakes as well. If the brake light illuminates, you know that something is up, but there are a few other things to look out for. Loud grinding or squealing noises are indicators of something being amiss as well. Grinding sounds can indicate something caught in the caliper unit, but you also might have grooves or warping on your rotors. You also might start to experience a "soft brake pedal," which can indicate fluid is leaking from your master cylinder or somewhere else in the braking system. It's important to use quality parts for brake repairs. Buying OEM brake parts for your Infiniti will ensure they fit properly and last a long time.
