What are the Symptoms of a Bad Brake Rotor/Disc?

Symptoms Of Bad Brakes Rotor/Disc?

If you’ve ever felt your steering wheel or your brake pedal shake/squeal when you tried to slow down or come to a complete stop, then you’ve just discovered a symptom of a bad or broken rotor/disc.

Reasons For Bad Brake Rotors/Disc

There are a few reasons for your brake rotors/discs to go bad.

  • The most common reason for a bad or broken disc/rotor is overheating from excessive brake use. Like when you are going down a mountain road.
     
  • Applying your brakes too hard while you’re traveling over 35 mph. Applying the brakes with such force causes the rotor to overheat when the friction from applied braking creates enormous heat causing the metal to expand and warp.
     
  • Letting your brakes go too long without changing them will also cause brake rotors/disc to wear down and grind the material off which could even cause the rotor/disc to explode.
     
  • Old Brake caliper hoses can deteriorate over time causing itself to internally collapse not letting pressure relieve itself after releasing the brake and damaging the rotors/discs.
     
  • The slides in the brake caliper bracket can cause damage from not being properly lubricated during brake service also.

Damaged Brake Rotors/Discs Affect Other Parts

Damage to your brake rotors/discs can affect more than just your brakes. They can cause a domino effect and damaging key parts and causing premature failure in others like:

  • The pistons inside of the calipers
  • Wheel bearings

The Danger Of Damaged Brake Rotors/Discs

Damaged brake rotors or discs can cause serious accidents. When your brake rotors/discs overheat while driving, the brakes can crystalize, which makes stopping using the brakes difficult if not altogether impossible. The hotter the rotors/discs are, the further it will take you to stop by several feet if at all.

Maintenance

If you hear squealing while applying the brakes then it’s time to replace the brakes. When you do change the brakes it is recommended that you also change the rotors/disc as well to be sure they do not wear out before your new brakes do. Always practice safety first when maintaining vehicle maintenance.
