Ever Heard of Slotted and Drilled Rotors?

The auto parts experts of one of the leading Leyland Spare Parts dealers say that one of the most important systems of each and every vehicle rolled out to date is undeniably the brakes. What’s the fun in going fast, slow or not moving at all, if the drivers don’t have the ability to stop at all, it will all feel same and monotonous? A smooth and optimally working braking system is not only quintessential for vehicle control, but also for the safety of the driver and co-passengers in it. It is only because of the brakes that we able to come out alive and injury-free during situations of collision and crash. It won’t do much for you, even if you own a stellar-looking car if it doesn’t possess a braking system that allows you to slow down at an intersection or while navigating a turn. Having a properly functioning brake system allows you to monitor your braking distance, gives an ultimate control of the overall driving experience and an invaluable piece of mind that you can brake late when needed.

Ever Heard of Slotted and Drilled Rotors?

Now one of the most integral parts of a braking system is the brake rotors. When the driver applies the brakes, that is, when he pushes hard on the brake pedal, it engages the vehicle’s master cylinder, which starts transporting brake fluid into the brake lines all the way to the brake calipers. Now, these brake calipers lined with the brake pads surround the outer of the brake rotors. When the brakes are applied, the brake pads squeeze the rotor surface, which slows and gradually stops the wheels from rotating,

Different cars come with different brake rotor designs. The two of the most popular brake rotor designs are cross drilled or slotted. Today we are going to talk about these two rotor designs, the difference between these and which of these rotors is better and why.

Let’s start with cross-drilled brake rotors.

Cross Drilled Rotors: You’ll normally find Cross Drilled Rotors on most of the high-end sports cars. They feel really fast when equipped with a normal parked car. Cross-drilled brake rotors are designed to provide an escape for the accumulated gas and dirt collected between the brake pad and brake disc. The holes drilled into the cross drilled rotors are there to provide instant cooling to the vast surface between the brake pad and brake disc. This is done by directly granting them a link passage to the interior cooling vanes of the rotor. This is how the surface area between the brake pad and brake disc increases and the brake temperatures decreases.

Slotted Drilled Rotors: Slotted Drilled Rotors are known for providing a significant power boost over smooth brake rotors that are common in normal parked cars. Due to heavy and sudden braking, the brake pads become prone to wear and increased outgassing. These two phenomenon cause the gas and dust to build up between the brake pad and the rotor surface. This causes a lapse in friction and in turn leads to “brake fade”. The friction surface of the Slotted Drilled Rotors has channels, or “slots” as the name suggests, machined into it.  These channels or “slots” provide an escape route for the accumulated gas and dirt collected between the brake pad and rotor. When the buildup gas and infinitesimal dirt particles are blown away from the surface, they basically follow the channels of the slot across the surface of the rotor, venting out heat as well, thereby reducing the likelihood of warpage due to overheating.
