KIA Sorento Brake Disc Problems and Their Causes
A powerful braking system is one of the most important assets of your Kia Sorento. This does not only ensure the vehicle's superior driving performance but also the driver's and the passengers' safety. Your KIA Sorento is equipped with sturdy brake discs that work efficiently with the rest of the brake assembly to guarantee superior stopping power everytime you step on the brake pedal. Although these discs are made from the finest and strongest metal components, excessive use and other factors still make them susceptible to damage and deterioration. When your brakes start to function differently than they used to, you'd better jack up your Sorento and check the discs for damage. Here are the most common KIA Sorento brake disc problems and their primary causes:
Cracks on the brake disc surface
Not all types of brake discs are prone to this problem, but this is very common among KIA Sorento vehicles, which are equipped with drilled brake discs. Cracking usually occurs on the drilled holes' edges on the discs' surface. This is caused by the uneven expansion rate of the discs, especially when they are regularly exposed to severe driving conditions. Because this is the normal wear mechanism of most cross-drilled brake discs, hairline cracks on their surfaces will initially cause no harm on the Sorento's braking mechanism. But if the cracks begin to worsen, they might result in a total brake assembly failure. When this happens, a KIA Sorento brake disc replacement is definitely in order.
Clunking noise from the brake disc
If your Sorento's brake assembly produces annoying noises everytime you hit the brakes, some of your brake discs are probably warped or damaged. If your discs are warped, the brake pads no longer have a flat surface to attach to. This produces the pulsating or clunking noise you hear from the brake assembly. Another reason for this would be worn wheel bearings. When the front wheel bearings have become worn over time, they will not be able to support the discs properly. This will allow the discs to wobble in place, which also causes the brakes to produce noise. Following the proper brake pad bedding or break-in instructions can help prevent premature brake disc warping.
Excessive brake vibration
Uncontrollable vibration while braking can be the result of warping or black spotting of the brake disc. Black spotting, which is signaled by the appearance of a hard spot on the surface of the disc, is usually caused by an overheating brake disc. This hard spot is actually cementite. It is formed when the cast iron material of the disc reaches high levels of temperature and then suddenly cools down due to unforeseen circumstances. You can check your brake discs for unnecessary vibrations using a dial indicator. When the problem is confirmed, the only solution is to replace the stock with a new one.
Other troubleshooting tips
Uneven braking is also a sign of a KIA Sorento brake disc problem. If your Sorento always pulls to one side everytime you apply the brakes, it is advisable to check the brake hose for leaks. Leakage in these lines can cause the rotors to be covered in brake fluid. Fluid contamination will affect the friction surface of the brake discs, which can cause the brakes to overheat and eventually fail.
Superior stopping power, hassle-free cornering, and comfortable pedal feel-you can enjoy all these benefits by having top-quality brake discs. But no matter how amazing your brake discs are, their everyday exposure to extreme temperatures and driving conditions still make them vulnerable to premature wear and failure. Your brake discs are bound to fail at some point, but you can do something to maximize their life span. Here are some easy but helpful tips in keeping your KIA Sorento brake discs in excellent condition:
Follow proper break-in instructions for new brake discs and pads.
It is important to perform proper bedding or break-in procedure for your new brake discs and pads. This process aims to deposit a thin and even layer of brake pad material on the surface of the discs to enhance the interaction between them and the pads everytime you step on the brake pedal. Bedding is essential if you want to achieve the best possible performance from your brake assembly, especially if the brake system components are newly replaced.
Replace or resurface the brake discs when changing the pads.
Experts recommend that you resurface your KIA Sorento brake discs everytime you change your brake pads. Actually, it is more advisable to replace the discs. But if you are a budget-conscious car owner, you can also opt to just resurface them. Doing this will prolong the life of your brake discs and improve the contact between the discs and the pads. This is especially true for high-performance brake pads.
Always check the brake assembly's hoses and connections for leaks.
Leaks in the brake hose can cause the brake fluid to contaminate the surface of your brake discs. When this happens, the leaking fluid from the hose will cover the layer of friction materials on the discs and pads, which will eventually lead to poor interaction between these brake system components.
Choose appropriate brake pads for your driving needs.
Your brake discs and brake pads always go together. This is the reason why it is very important for you to choose the right brake pads that suit your driving habits and your vehicle's regular driving condition. A perfect pad and disc combination will not only give you a comfortable and excellent driving performance, but it will also extend the life of your brake assembly, especially the brake discs.
Clean your rotors regularly.
Just like any other part of your vehicle, performing regular cleaning on your brake discs can help keep them in their best condition. Road dirt and other debris, which have accumulated in the brake discs, can compromise the discs' performance. Removing these contaminants and keeping your discs clean using a commercial rotor cleaning spray will allow you to enjoy rust-free rotors with absolutely longer life spans.
