6 Common Myths About Car Brakes Debunked

Oct 23,2024 | CosmoCarCo

Understanding your car’s braking system is crucial for maintaining safety on the road. Let's dive into the six most common myths about brakes and uncover the truth behind them.

Myth #1: Noisy Brakes Mean They Need Replacement

It’s a common assumption that noisy brakes are a clear indicator they need to be replaced.

While it’s true that some brake pads are designed to emit a sound when they wear out, not all brake noises signify a problem.

High-performance brake pads, for instance, can make noise due to the friction materials they use. These materials are designed to endure high temperatures and may squeal under normal braking conditions.

Some competition-grade calipers also produce knocking sounds due to the fitment allowance for expansion and contraction.

This prevents the calipers from seizing under high heat. Street calipers, however, are typically quieter.

To ensure your brakes are in good condition, rely on visual inspections and follow the manufacturer’s maintenance schedule.

Myth #2: Less Brake Dust Means Better Brake Pads

Brake dust might be unsightly, but it’s a natural byproduct of the friction necessary for braking.

High-performance pads and rotors often produce more dust, which is a sign of their effective friction capabilities.

Some ceramic or Kevlar brake pads might advertise less dust, but they still produce it in a less visible form.

When choosing brake pads, focus on performance rather than the amount of dust they produce.

Regular car washes will help keep your vehicle looking clean despite the brake dust.

Myth #3: Big Brake Kits Guarantee Instant Stops

While upgrading to a big brake kit can improve your car’s braking force, it’s not a magic solution for instant stopping.

Bigger calipers allow for larger pads and rotors, increasing the surface area for better heat dissipation and reducing the risk of brake fade.

This provides consistent braking performance, especially under intense conditions like track days or fast road driving.

However, for significantly improved stopping power, start with better tires and high-quality brake fluid.

These elements are crucial for effective braking performance.

Myth #4: Cooling Hot Brakes with Water is Safe

Pouring water on hot brakes is a big no-no.

Braking components expand and contract with heat, and rapid cooling can cause warping.

Warped rotors can lead to vibrations in the steering wheel and significantly reduce braking efficiency. In extreme cases, it can lead to complete brake failure.

The best way to cool down brakes is to simply let them rest.

After a spirited drive, park your car and allow the brakes to cool naturally before washing your vehicle.

Myth #5: Drilled or Slotted Rotors Are Always Better

Many believe that slotted or cross-drilled rotors are inherently better because they look high-tech and seem to promise better cooling.

While all modern brake rotors are ventilated, the additional drilling or slotting can help with heat dissipation and improve wet weather braking.

However, these designs also have drawbacks.

Cross-drilled rotors are more prone to developing hairline cracks, and slotted rotors can wear down brake pads faster than standard rotors.

It's essential to weigh the benefits against the potential downsides based on your specific driving needs.

Myth #6: Upgrading to Big Brake Kits Requires All Four Brakes

A common misconception is that upgrading the front brakes necessitates upgrading the rear brakes to maintain balance.

In reality, up to 80% of your car’s braking power comes from the front brakes.

Upgrading the front brakes can significantly improve overall braking performance without the need for rear upgrades.

Adding big brake kits to the rear can complicate things, such as requiring dual caliper setups to maintain handbrake functionality.

Upgrading just the front brakes can enhance fade resistance and heat dissipation where it matters most.

Conclusion

Understanding these common myths about car brakes can help you make better decisions for maintaining your vehicle’s safety and performance.

Always rely on expert advice and regular inspections to keep your braking system in top shape.
