How does summer heat affect car brakes?

The summer sun that produces stifling heat can take its toll on many things. That is, he makes us drowsy on the couch and doesn’t invite us out until dawn. But what about the car? We know that over time the sun will start to fade the paint and ruin the windows, and that’s just on the outside. The heat also heats up the rubber and plastic components inside. And of all these things that are affected by the sun, Have you ever thought that heat affects the brakes?

Because, indeed, heat is a great enemy of car brakes. Heat is created naturally by friction when braking, and when you add to that the higher-than-normal ambient temperatures in summer, can wreak havoc on your brakes. Fortunately, manufacturers have spent years perfecting brake pads to make them more resistant to heat caused by friction and temperature. As a curiosity, in an average car, the discs They can reach 150 °C, and more than 250 °C in heavier vehicles.

Over time, the heat generated from friction can cause wear and tear on brake components. However, extreme heat within the braking system is a problem. If the brakes become severely overheated and cannot cool, the brake system is likely to begin to fail. With the additional heat brought on by summer, the chance of component failure increases greatly. If these are not of good quality, it is possible that there is not enough material to dissipate heat properly.

When heat is prevented from escaping, the brake fluid can begin to boil, reducing braking power and creating the sensation known as “it won’t stop.” When the temperature is high, above 30 °C, the cooling capacity of the brake discs and pads is proportionally reduced, something that also happens with the fluid. In this sense, it must be emphasized that heat evacuation in summer is more difficult and discs can even become deformedjust as brake fluid could boil.

Thus, at high temperatures, the brakes can overheat due to friction against the disc. In this sense, if after a heat wave or during the high temperatures in summer we observe symptoms such as noises or vibrations when braking, that the brake pedal sinks, is very hard or loses braking capacity, We should have the brake system checked as soon as possible. Therefore, always make sure you have your brakes in the best possible condition with a routine inspection and regular maintenance.
