A Look at the Differences Between Slotted and Cross Drilled Brake Rotors

2

Even though there are several kinds and designs of brake rotors, it is no secret that the most common ones are that of the cross drilled and slotted varieties. So, if you were asked to make a comparison of brake rotors, these two should fit the bill as your main options because the rest seemingly aren’t as relevant as these two.

Perhaps the most important information you need to know at this point is that both cross drilled and slotted rotors are specifically designed in such a way that they allow gases that have the tendency to build up in between the rotor and brake pads to escape. What therefore happens is that the brakes are properly maintained and cooled, which in turn allows a better stopping performance. Keep these in mind when thinking about brake rotor replacement.

Cross Drilled Rotors

The idea behind the invention of the cross drilled rotor is to allow heat to naturally escape once it begins to build up in between the brake pad and rotor and those drilled holes serve as the gas’ escape route. One of the reasons why many people fancy cross drilled rotors is because they look great, but it’s not to be ignored that there have been several instances in which cracks developed in between the drilled holes. But the usual cause is because the rotor was made using low quality material. Therefore, even if the cross drilled rotor is designed to expel hot gas, there still is a tendency for it to crack and deteriorate fast if it’s made out of low quality material. In case you are leaning towards buying this type of brake rotor, our recommendation is to buy it from a renowned brand.

Slotted Rotors

Meanwhile, slotted brake rotors are considered the best alternative to the drilled variety because they serve the same function of expelling hot gas while diminishing the risk of cracking. If cross drilled versions are great in terms of aesthetics, industry experts agree that slotted rotors are designed mainly for race as well as performance. Slotted brake rotors are also great in wet conditions because their design ensures that water stays away from the rotor, which means braking isn’t affected by the water at all.

Many brake companies and manufacturers these days lay claim to the notion that their rotors can last significantly longer than stock rotors. Also, they claim that there also is lesser brake fade. It’s really up to the consumer like you to believe them or not. In the end, if you’re looking to improve braking performance either for racing purposes or just in normal driving conditions, you have the freedom to choose between cross drilled and slotted variants. And don’t forget to buy and install good quality brake pads.
