Nissan Xterra Brake Rotors: Finding the Root of the Problem
Your Nissan Xterra brake rotors are capable of slowing down and stopping your wheels as soon as you step on your brake pedal. Generally, these rotors can withstand extreme conditions with their tough construction. But even if they're built extra tough, your Xterra's rotors will probably still go bad and perform poorly at some point in their lifespan. If your brake rotors are acting up lately, you need to check on them and do some troubleshooting right away. Finding the root of the problem can be challenging, but we're here to help you out. Read the troubleshooting guide below to determine the symptoms of brake rotor damage and the common causes behind them.
Pulsating sensations and grinding noises
Bad brake rotors pulsate and produce low grinding noises when you step on the brake pedal. The pulsating sensation will be present even if you're not pumping the brakes. This is usually matched by a low grinding noise that gradually becomes louder as the condition of your Xterra's rotors worsens. As soon as your brake rotors start to pulsate and become noisy, have them checked right away or replace them before they jeopardize the operation of your Xterra's brake system.
Aside from these warning signs, damaged rotors may also cause your vehicle to vibrate or shake when the brakes are applied. Your steering wheel may also vibrate when you have bad rotors. Check your brake pedals if you're encountering these problems. Chances are the pedals are already worn out, and their metal screws are rubbing against the surface of the rotor, forming ridges. Replace the damaged pedals before they completely destroy your rotors. Better yet, replace your rotors if they're already damaged beyond repair. You can also use a micrometer to gauge the thickness of the grooves on the rotors. A mechanic can help remove these grooves, but it would be best to replace the entire rotor if the grooves are already too deep.
Damaged brake pads, defective brake calipers, and a bent hub assembly can cause your brake rotors to become warped. Extreme heat and brake pad friction, along with excessive turning and squeezing action from the hub assembly and calipers, can severely damage and warp your Nissan Xterra brake rotors. Replace these parts if they're damaged to prevent the rotors from warping.
