Understanding Brake Discs
Brake discs, also known as brake rotors, are a critical component of your vehicle’s braking system. They’re attached to the wheel hub and work in conjunction with brake pads to slow or stop your car. When you press the brake pedal, the brake pads press against the brake discs, causing friction that slows down your vehicle.
Types of Brake Discs
There are two main types of brake discs: solid and ventilated.
- Solid brake discs: These are the most common type of brake disc and are designed for most passenger vehicles. They’re made of a solid piece of metal and are less expensive than ventilated brake discs.
- Ventilated brake discs: These brake discs have holes or slots that allow heat to escape, reducing the risk of brake fade. They’re typically used in high-performance vehicles or those that tow heavy loads.
Signs of Worn-Out Brake Discs
Here are some common signs that indicate you may need new brake discs:
- Scoring or Warping: If your brake discs are scored or warped, it can cause vibrations when you brake. This can be felt through the steering wheel or seat.
- Thick, Black Residue: If you notice a thick, black residue on your brake discs, it may be a sign that they’re worn out. This residue is caused by the brake pads wearing down and depositing material onto the brake discs.
- Noise When Braking: If your brake discs are worn out, you may hear a grinding or screeching noise when you brake. This noise can be caused by the brake pads rubbing against the brake discs.
- Brake Pads Wearing Down Faster: If your brake pads are wearing down faster than usual, it may be a sign that your brake discs are worn out.
