What is Mazda Smart Brake?

  • Mazda Smart Brake is also considered Smart City Brake Support Forward (SCBS-F).
  • Using a signal on the display and a warning sound, the Smart Brake System informs the driver of a possible accident.
  • The system is a high performer since it will notify you and automatically brake when the risk is higher.
  • A laser sensor positioned on the windshield is used by SCBS to track and detect the car in front of you.
  • The braking system runs at speeds of 4 to 80 km/h.

What does the “Smart Brake Support” warning light mean?

When the Smart Brake Support system activates the light, it typically does so because the windscreen or perhaps the radar sensor is dirty; for example, when it rains, the windscreen is fogged on both the interior and exterior sides or when there is rainfall on the outside side of the windshield.

Therefore, clean the windshield. If you see fog, turn on defrost on the inner side of the windshield. Also, you might need to check the owner’s manual or take the vehicle to a licensed Mazda dealer if you somehow find the light is still on even after defrosting.

Is it safe to drive with the brake warning light on?

No, you shouldn’t drive your automobile until a mechanic has fixed the issue. Basically, a brake warning light signals a brake system issue.

According to information shared by one user, Mazda seized the 2017 Mazda CX-9 Azami in December 2018 after 19,800 kilometers due to a serious brake system malfunction. Basically, the active safety features and pre-crash features found in Mazda cars are designed to minimize crashes. However, if it malfunctions, you must fix it as quickly as you can because it could result in a severe injury that could possibly be deadly.

For example, your smart city brake support may malfunction in a Mazda 6, and a brake warning light can sometimes warn of low brake fluid or a braking system leakage in your vehicle. Another possibility is for a connecting cable to separate or move drastically out of alignment. If your brake warning light illuminates, you should pay attention and contact your repair service right away.

What causes Mazda SCBS or Brake system malfunction?

  • The first culprit is a brake line leak that makes the smart city brake support turn off. Your car’s brake system might be triggered by hydraulic fluid leaks.
  • You’ll probably notice that the brake fluid gradually degrades until there is not enough of it to transmit the pressure from the pedal to the tires.
  • When the discs lose their ability to provide enough friction to stop the wheels due to wear, the brakes may also stop working.
  • We also discovered overheating brake pads, which interfere with the brake system.
  • Traction between the wheels and the ground and damaged rotor disks might result in brake problems.
  • Riding on rough places like mud or water possibly causes the braking system to fail.
  • Additionally, a car’s braking system may occasionally be blocked by overload.
