Brake rotors or brake pads are an essential part of your vehicle and the only part that stops your wheels from moving after the brakes are applied. They are designed to slow the vehicle down by converting kinetic energy into thermal energy, or heat. This entire process however, creates so much heat that needs to be quickly dissipated to prevent warping or bending. Over time, brake pads eventually wear out and the period depends on how they have been used, terrain, and even the weight of the car. However, to understand when to change the brake rotors, it’s important to first understand how they work.
How Brake Rotors Work
When you press the brake pedal, hydraulic fluid is sent from the master cylinder to the brake calipers, which are located at each wheel. The calipers contain a piston that pushes against the brake pads, which are made of a friction material. The brake pads are then pressed against the brake rotors, which are metal discs attached to the wheels. As the brake pads squeeze against the rotors, the kinetic energy of the moving vehicle is converted into heat. This heat is dissipated through the rotors and the brake pads, and it is this process that slows the vehicle down.
When Should You Change the Brake Rotors?
The most common signs for defective brake rotors are vibrations when brakes are applied, a squeal sounds when you engage the brakes and some brake dust. In fact, if you notice that your wheels are covered in brake dust, it may be an indication that your rotors are worn and need to be replaced. If you feel vibrations or pulsations when you press the brake pedal, it may be an indication that your rotors are warped or unevenly worn. The same goes for if you notice grooves on the rotors as they could be indicative of worn out brake pads.
Tips to Lengthen the Longevity of Your Brake Rotors
Some motor enthusiasts make adjustments on their brake discs to make them more effective and to dissipate more heat. You can choose slotted rotors since they are known to mitigate against brake pad outgassing. These slotted rotors however wear out faster since they expose underlying surfaces faster with each braking and are therefore only ideal for shorter use spans. You can mostly find them in competitive arenas or in vehicles that don’t stay on the road for long, such as show cars.
How Driving Styles affect Longevity of Brake Rotors
It is also important to consider the type of driving you will be doing when choosing brake rotors. If you will be driving in wet or rainy conditions, you may want to choose rotors with a slotted or drilled design. These rotors have small holes or slots cut into them to help evacuate water and debris from the braking surface. This can help improve braking performance in wet conditions.
Conclusion
Brake rotors are an essential component of a vehicle’s braking system. They are designed to convert kinetic energy into heat to slow the vehicle down. There are several factors to consider when choosing brake rotors, including size, material, driving conditions, and quality. By taking the time to choose the right rotors for your vehicle, you can help ensure optimal braking performance and safety
