How Often Do Brake Discs Need To Be Replaced?
Your car's braking system is arguably one of its most critical safety features. Among its components, brake pads and discs play a pivotal role in ensuring your vehicle comes to a stop safely and efficiently. But just how often should you change these components? In this blog, we'll answer common questions like "Can you drive with bad brake discs?" and "How often should you change brake discs?" to help you maintain a reliable and safe braking system.
Can You Drive with Bad Brake Discs?
No, you should not drive with bad brake discs. Brake discs, also known as rotors, are vital for stopping your vehicle effectively. When they become worn or damaged, they can compromise your car's braking performance, leading to longer stopping distances and reduced safety. Driving with bad brake discs is not only risky but also illegal in many places.
How Often Should You Change Brake Discs?
The frequency of brake disc replacement depends on various factors, including your driving habits, the type of brake discs, and the quality of your brake pads. On average, brake discs can last anywhere from 30,000 to 70,000 miles. However, it's essential to monitor their condition regularly and replace them when they show signs of wear or damage.
How Do I Know if My Brake Discs Are Worn?
There are several signs that indicate your brake discs may be worn and in need of replacement:
Squeaking or Squealing: If you hear high-pitched noises when applying the brakes, it could be a sign that your brake discs are worn, and the brake pads are scraping against them.
Vibration or Pulsation: If you feel a vibration or pulsation in the brake pedal when braking, it may be due to unevenly worn brake discs.
Reduced Braking Performance: Longer stopping distances or a less responsive brake pedal can be indicators of worn brake discs.
Visible Wear: Inspect your brake discs for visible signs of wear, such as grooves, scoring, or uneven thickness.
Can You Replace Brake Discs Without Pads?
While it's possible to replace brake discs without changing the brake pads, it's not recommended. Brake pads and discs wear together, and replacing one without the other can lead to uneven braking, reduced performance, and potential damage to the new components. It's generally best to replace both brake pads and discs simultaneously to ensure optimal braking performance and safety.
Are Worn Brake Discs an MOT Failure?
In many places, including the UK, worn or damaged brake discs can result in an MOT (Ministry of Transport) failure. MOT tests check various safety aspects of your vehicle, and if your brake discs are found to be excessively worn, your car may not pass the inspection. Regular maintenance and timely replacement of brake components can help ensure your vehicle meets the necessary safety standards.
Brake pads and discs are integral parts of your vehicle's braking system, and their condition directly impacts your safety on the road. While there is no fixed interval for replacing them, monitoring their condition and responding to signs of wear or damage is crucial. Remember, driving with bad brake discs is not only unsafe but also potentially illegal. Regular maintenance and timely replacements will help keep your braking system in optimal condition and ensure your vehicle stops reliably when you need it to.
