FAQs— Infiniti Brake Disc and Pad Kit
- When driving my Infiniti on dewy mornings, I noticed swishing noise as I apply the brakes. Is that something I should worry about? Does that mean I now need a new Infiniti brake disc and pad kit?
That swishing or grinding noise is but normal on rainy or dewy mornings, but the noise should go away as the pads warm up and the moisture accumulated overnight is driven away from the brakes. It’s also possible that the noise is created by the pads as they sweep away the thin layer of rust that has formed on the surface of the disc.
- When looking for an Infiniti brake disc and pad kit, I noticed that there are two types of holes on the rotors that come along with the kits—cross drilled and dimple drilled. What are these holes for?
Performance rotors are usually dimpled drilled and/or cross drilled. Dimpled holes are made by drilling without completely creating a hole through the pad surface. The dimples promote heat dissipation while maintaining the strength of the rotors. Dimpled rotors are recommended for heavy vehicles and for those that have problems with warping rotors. Cross drilled holes, on the other hand, are created by completely drilling through the disc surfaces, hence allowing air to pass through for faster heat dissipation. Cross-drilled rotors are commonly used on light- to medium-duty automobiles and on high-performance vehicles.
- If drilled rotors have several advantages, does using them on my Infiniti also has disadvantages?
Yes, there are pros and cons to using drilled rotors, and among the disadvantages is that the holes usually weaken the rotors. If you engage in repeated stressful driving or you always do hard braking, the rotors can crack.
- I’m pretty sure that I have sufficient brake fluid left in the reservoir, but my friend told me to constantly check it as I carry out my DIY brake pad replacement project. Why is that so?
You have to keep track of your brake fluid level because it slowly rises as you push the piston back in place. This is particularly important when you’ve already installed the brake pads on one side since the fluid level has already increased during installation. Expect the fluid level to rise further as you retract the piston on the other side. If you think the fluid will overflow, better get a turkey baster to suck out some of the fluid. You must prevent such fluid from overflowing as it is highly corrosive. You can just top it off as soon as you’re done and the amount of fluid in the reservoir is below the "MAX" level.
- Do the grooves on my Infiniti brake disc indicate a need for a new brake disc and pad kit? Is there any alternative to replacement?
If the grooves are deep, you have no other choice but to replace your brake disc. Grooves on the rotors will make the pads touch only the highest point, therefore reducing its braking power. As the pads are pressed against the rotor, deep grooves also shred the friction material. Also, the rotor will lose its ability to evenly distribute the heat produced when braking, causing hotspots.
- My brakes squeal as I depress the brake pedal. When I take a look at the assembly, it seems like the rotors have surface rust, probably because it’s been sitting in the garage for a while now. Does the disc warrant replacement?
If the rotors have surface rust, it’s normal for the brakes to squeal the first few times you apply them. This squealing sound should slowly vanish as the rust wears off. But if the squeal remains evident every time you step on the brake pedal, that means the rust has eaten up parts of the rotor’s surface, and this warning sign should be acted upon immediately.
- I’ve just installed a new Infiniti brake disc and pad kit. But, during my test drive, I noticed that the pads are noisy. What could be causing this? And how can I fix this problem?
It could be because the pads don’t fit tightly in the calipers. You may need to check your brake assembly once again if you want to have it fixed. Pads with mounting tabs or ears on a single caliper piston shouldn’t wiggle, especially when moved by hand. For pads with anti-rattle springs, clips or shims, double check if all the necessary hardware are properly installed in place.
Choosing the Right Infiniti Brake Disc and Pad Kit
One of the most important parts of any vehicle is the brake system. It is responsible for ensuring your driving safety while on the road. Because of this, it is also one of the most prone to succumb to premature wear. Among its parts that usually wear out faster than the others are the brake pad and disc. Over time, these parts get damaged due to frequent use. That's why you should always keep in mind to replace these parts at least once a year. When it's time to replace them, you can buy an Infiniti brake disc and pad kit from your trusted supplier.
Right kit for the right reasons
Every vehicle has its own unique attributes. This also holds true when buying your new Infiniti brake disc and pad kit. Here are a few factors to consider when buying a brake disc and pad kit.
- Type of vehicle. Whether you own a van or a sedan, you can always find the perfect, custom-fit brake pad for your vehicle. Each brake pad and disc is made for specific applications to ensure that they will always perform at their best.
- Driving style.Every driver has a specific driving style, and fortunately, there are brake pad and disc kits that are tailor-made for each of them. You might be more frequent driving in streets or major highways, or you might be spending more time driving over rough terrain. Regardless of your driving needs, you need to consider it before buying a new kit.
- Budget.While there are aftermarket brake pad and disc kits that are of high quality yet expensive, there are also several options that are cost-efficient but of good quality. You may opt to go for this type because you can always replace it after a year. If you cannot afford the branded ones, you can just go for OEM parts that offer the same quality but cheaper price.
- Size. As mentioned above, every vehicle has a specific type of brake disc and pad that will fit perfectly. It is important that you check the diameter of your vehicle's brake disc before you buy a replacement part. You need to determine the brake disc thickness using a digital micrometer or a measuring tape, whichever is available. You also need to take note of the diameter, number of holes, fitting position, pitch circle, and wheel hub diameter.
- Wear warning contact.It would greatly help if the brake pad that you will buy has a brake wear indicator also known as a wear warning contact. This helps you to become aware when you need to replace your pads. This keeps you from overusing your worn-out pad by informing you ahead that it is already up for replacement.
You might also want to consider if the Infiniti brake disc and pad kit that you are buying is backed even by a limited warranty by the manufacturer. This helps ensure that the items are made of quality materials and will not get worn out easily.
