If you have been driving in your vehicle and you have been on a nice long road trip, and notice your brakes act shaky, this means that you have come across a brake pulsation. A brake pulsation is something that generally happens after you have been driving for a small period of time. The reasons for this occurrence can be vast, and they can range from warming up the brakes to damage in the interior.
Heated Up Brakes
If you have warmed up your brakes to some extent, going on a long drive can mean that you will have to face brake pulsation. Once you out too much stress on the brakes after driving them for too long, that’s when you will start to notice the discrepancies in the rotors.
Brake pulsation can come from different parts of the car. If you step on your brakes and feel that the steering wheel is shaking around too much, then it is more than likely that the brake pulsation is coming from the front brake rotors. On the other hand, if you feel the brake pulsation coming throughout the vehicle, or in the rear seat, then it is more than likely that your rear wheel rotors are troubling you.
Most Common Brake Pulsation Issue
The most common place for you to have a brake pulsation is going to be the front brakes. The reason why your front brakes are often the cause is because the majority of your braking power travels to the front. That being said, it is important for the front rotors to be much thicker than the rear rotors. Your front rotors are going to be thick, and they are also going to have cooling fins in them.
This unique design of your front rotors allows them to dissipate the heat properly. If there is going to be an issue with the front rotor components such as the braking surface and cooling fins, then pulsation will be the resulting problem.
The Rear Brakes & Rotors
The rear rotors are much thinner than the front rotors. The reason for that is that your rear brakes are mostly for stabilizing your vehicle when you are braking. The thinner rotors are however only for small passenger sized vehicles. If you have an SUV or a truck, then you will need a larger braking surface.
Cause and Fixes
Brake pulsations are often a cause of warped or unbalanced rotors. The main cause of warped rotors is overheating. The reason why your brakes overheat is because of rotting cooling fins or sticking pin conditions. One of the easiest fixes against the brake surfaces is precautionary maintenance. The more you focus on timely rotor cleaning, brake fixes and replacements, the less likely you will run into this problem.
Pulsating or surging brakes is a sign that ultimately occurs as a drastic byproduct of friction. This friction is caused due to two metallic components rubbing against each other. Overall, a pulsating brake must be looked at urgently since brakes need to be optimum for safety.
