4 Symptoms of a Faulty or Weak Brake Discs

To slow the car down, metal disc brakes work in tandem with brake pads and calipers. Brake discs spin at the same pace as the wheels because they are attached directly to the wheel hub.

When the brake pedal is pressed, the calipers force the brake pads against the spinning discs, slowing and halting the wheels and the car. Because discs slow the vehicle by generating friction from direct contact with the brake pads, they will eventually wear out and need to be replaced.

Check your car's MOT status and get the brake discs replaced as soon as possible to prevent failing your next MOT test.

When discs fail, they generally generate one or more of the following four symptoms, which tell the driver that they need to be replaced:

1.      Noisy Brakes - One of the most prevalent indications of damaged brake discs is noise. Squealing or squeaking noises can be heard if the discs are deformed (not completely flat) or significantly worn. A squeak is usually produced by warped discs, whereas a scraping sound is produced by highly worn discs. However, the screeching noise might also be caused by worn brake pads. If you go online and type 'check my MOT history' for your vehicle, you'll be able to see if the brake discs have been a cause of MOT failure in the past.

2.      Brake Vibrations - Excessive brake vibration or pulsing is another symptom of worn brake discs. Vibrations in the pedal and, in certain situations, the steering wheel or chassis can be caused by warped or badly worn discs shaking uncontrollably. Additionally, when the brake pedal is pushed, it may appear to be pulsating due to warped brake discs. Because the pedal no longer contacts the brake discs surface, this occurs. To avoid failing a MOT test and for safety reasons, check MOT status of your vehicle and get a brake disc replacement completed by a mechanic.

3.      Visual Scoring or Grooves on The Disc - This is another sign of faulty or weak discs. These markings appear because of repeated contact with the brake pads. The thickness of discs is meant to decrease over time. If it deteriorates to a certain extent, though, it compromises the vehicle's overall safety. If you check MOT history of your car, scored or grooved brake discs are a common reason for failure.

4.      Stopping Distance Increased - A disc's scoring and grooves can reduce its ability to slow the car, as well as generate vibration and pulsation in the pedal. Furthermore, when the brake pedal no longer engages with the brake disc, the resulting vibration may give the impression that the vehicle will not stop at all. When a vehicle is compelled to make an emergency stop, the inability to stop or even longer stopping distances can be extremely dangerous.

The disc brakes are an integral element of the braking system and, as such, are crucial to the vehicle's overall safety and handling qualities. Whether you believe your brake discs are worn or broken, have your car evaluated by a competent mechanic to see if you need to replace them.

When It Comes to Brake Discs, How Long Do They Last?

Bringing your vehicle to a complete stop is an important element of remaining safe behind the wheel. Most vehicle owners are unaware of how many components must work together in order for the braking system to function properly. The rotors are the metal discs that are installed behind the car's wheels. When the brake pedal is depressed, the calipers press down on the pads, which subsequently use the discs to provide the necessary resistance to stop the car. The vehicle's discs are only activated when the brake pedal is depressed.

The brake discs will need to be changed over time because of the amount of usage they receive. A car's brake discs should last between 50,000 and 70,000 miles on average. Brake pads may generate a lot of heat due to continual contact. It is possible for the discs to distort if they are extremely heated and then put in a puddle of water. A warped disc may only be repaired by replacing it.
