Causes of brake smell

Brakes are an essential part of any vehicle, ensuring safety and control on the road. However, sometimes they can emit a distinct smell that might raise concerns. Let’s explore the causes behind this phenomenon and shed some light on why your new brakes might have an odor.

When it comes to brake smell, one common cause is overheating. Excessive friction between the brake pads and rotors generates heat, which can result in a burning scent. This is particularly common with new brakes as they need time to bed in properly. The initial break-in period involves transferring a layer of material from the brake pads to the rotors, resulting in increased heat generation and subsequent odor.

Another potential cause of brake odor is resin buildup. As the brake pads wear down, they release resin that can accumulate on the rotors. This resin buildup can lead to a distinct burning smell when brakes are applied due to its exposure to high temperatures. It’s important to note that excessive resin buildup may be indicative of underlying issues with your braking system and should be inspected by a professional.

Furthermore, certain driving conditions can contribute to brake smell. If you frequently engage in heavy braking or drive in hilly areas where constant pressure is applied on the brakes, it’s natural for them to emit an odor. Additionally, towing heavy loads or driving in stop-and-go traffic can also increase the likelihood of experiencing a noticeable brake smell.

To better understand the causes relating to brake smell, let’s delve into a true history associated with this topic. One famous incident involves race car drivers complaining about their new carbon-ceramic brakes emitting a peculiar smell during high-speed races. This led to investigations and breakthroughs in developing improved braking materials that could withstand extreme conditions while minimizing odors.
