The Car’s braking system is of paramount importance to your safety. You need to be able to stop at a moment’s notice, or to slow down to avoid an accident or incident while driving. If your brakes are not working in the correct manner, as they are designed to do, in a panic and stop situation they will not be effective. There are many components to a car’s braking system that all have to co-work to give an efficient stopping outcome. Rotors are discs of metal that are mounted behind the wheels that react when the brake pedal is pressed down; the brake callipers push down onto the brake pads, which in turn use the rotors as resistance to allow the vehicle to come to a stop.

Inspection of brakes

We recommend that your brakes are inspected regularly, with an actual visual check of the brake pad and thickness of the brake shoe. Rotors should be inspected for hot spots and run outs, and the wheel cylinders, brake master cylinder and brake lines are all in good, serviceable order. The condition and level of the brake fluid should be checked, as should the brake and antilock brake sensors.

Replacement of brake rotors

Expect to replace brake rotors over time, as a result of the amount of use they receive. Lasting usually between 50,000 and 100,000 kms, the wear appears as a result of constant friction. They also have a tendency to warp, if they are heated due to friction, then you drive through water, resulting in the need for replacement rotors. As the brake rotors are mandatory in the car’s braking operation, you will notice when there are wear and other issues with them.

Some of the problems you will notice when the brake rotors need replacement are:

  • Noticeable roaring or squealing noises when you brake and attempt to stop your car
  • Vibration when attempting to bring the car to a stop
  • Scratches or spots on the brake rotors
  • Noticeable grooves worn into the rotors
  • The car will pull to one side when attempting to brake

Inspection and replacement of brake rotors

It’s advisable to get the brake rotor thickness measured at least annually. A trained motor mechanic should measure and advise the thickness each time the brake pads are changed. In some cases, it is possible for the mechanic to machine the rotor to remove the wear spot if they are not too worn. Getting any issues with the brake rotors inspected and repaired as soon as possible will reduce the amount of damage and be more economical in the long run.
