Bidirectional Slots For Increased Braking Performance - Expel hot gases from disc surface friction, disperse heat and reduce the chance of overheating warping. It also ensures optimum contact between the rotor and brake pads as brake dust particles are separated from the friction ground. Precision Drilled For Exceptional Heat Dissipation - Increases air movement so that the spinning disc cools more rapidly and uniformly. The transfer of heat to the other elements of the braking system is less.
It also improves the efficiency of rainy weather by allowing water to evacuate through integrated channels. They also extend the existence of the brake pad in normal conditions of driving. G Cast Iron - They are built to reach a tensile ratio of 1. The friction on the uncovered brake surface stops rust from accumulating.
Unlike spray-painted coverings, they resist losses from a solvent-based brake cleaner. This two-way rotor can be mounted on either side of the engine. You will not need any special equipment or adjustment. Brake Cleaner For Professional Strength Degreaser - Strong and persistent pressure can be fulfilled in the whole field.

Brake discs also vary depending on the type and the material they are made of. If you are considering the material and design, then you must know whether you are going to take your car on the track, highway, or off-road. Listed below are the performance options available. Most of the vehicles that come straight out of the factory have a blank also known as the smooth brake discs. This rotor provides a full-face friction surface for the brake pads to clamp down.
This generates friction to slow down your vehicle. Most buyers chose smooth rotors as they are affordable, inexpensive to manufacture, and offer durable braking performance under normal conditions for thousands of miles.
These rotors have drilled holes on the surface of the rotor so that the generated heat dissipates quickly. This provides a long braking performance for the vehicle and reduces the brake fade during heavy braking. Also, the holes help the water escape quickly during wet weather before it affects the initial braking.
If you are a car enthusiast looking for a rotor upgrade that performs great in all-weather, then the cross-drilled rotors are the best choice. You can find thin slots or lines on the surface of the slotted rotors. Similar to the cross-drilled rotors, slots are an effective measure to improve cooling and remove water quickly. Also, the gases formed because of excessive heat can escape through the slots minimizing the brake fade. Just as the name suggests, these rotors have the advantages of both the drilled and slotted brake rotors.
Drilled and slotted brake rotors are best suited for any car enthusiasts, street performers, or any drivers who are looking for the ultimate driving performance for their vehicle. Some of their features are - quick response in wet and dry conditions, heat dissipates quickly, reduced brake fade, and longer life span. They are an expensive option available in the market. You can always choose the drilled and slotted rotors for best performance, as it has the advantages of both the drilled as well as slotted disc rotors with minimal side effects.
The slots can help you eliminate the gas and dust and the drilled holes help in cooling the heat that is generated because of heavy braking. You will start facing issues if your disc rotors are under-performing. Disc brake rotors are made of different materials and their performance is not the same. Look below to make the right choice. Cast iron is the most frequently used material for the production of brake rotors. High performing vehicles will need a two-piece cast iron rotor.
But the heavy material increases the total weight of the vehicle. This added weight falls straight onto the front wheels, making it a little difficult to manage. In this process, sheets of steel are placed one upon the other and laminated together. They are durable and provide resistance to warping. And, hence they have become the recent favorites among the racers.
As this rotor is not popular among general people, their production is limited. Though aluminum brake rotors dissipate heat quickly, they have a lower melting point which means they can potentially melt at lower temperatures and can not be used in high-performance vehicles.
Hence they are used only in motorcycles, as they take less pressure when compared to the rotors in the car, trucks, or SUV. These rotors dissipate heat quickly and they do not crack under pressure. They are also lighter meaning you will shed at least 10 pounds of rotating weight, thereby increasing the braking performance. They make less noise and vibration and hence they are best suited for high-performance oriented applications like drag cars.
The only downside to this rotor is the high-price. The potential reason as to why you must upgrade your brake rotors is improved performance and better vehicle safety. Upgrading brake rotors will help you in the following ways:. Better Braking Performance - If the disc brake rotor on your vehicle is worn out, then they can affect the braking performance.
Your vehicle will take a longer time than usual to come to a stop. Upgrading your vehicle with top-rated disc-brakes will shorten the braking distance minimizing brake fade. Smooth Braking - Disc brakes will make your brake pedal feel less spongy and responsive every time you step on it. You may also feel that the vibration is less, as you apply the brakes.
Better Performance In Wet Weather - If you upgrade your vehicle with premium disc brake rotors such as cross-drilled, drilled or drilled and slotted rotors, they will enhance the braking performance in wet climates as water escapes quickly through the slots or drilling. Longer Lifespan - The brake pads along with the disc brake rotors can enhance the braking performance and withstand for a longer lifespan if they are upgraded together at the same time.
You are also sure to get maximum mileage out of them. Though the disc brake rotors are designed to withstand for a longer time, they wear out eventually. If your disc brake rotors are worn out, they will show you a few signs, which means you will have to look out for a replacement before they damage other parts and result in expensive repairs. Some of these signs are:. Squealing Noise While Applying Brakes The very first symptom of a failing disc brake is the squealing noise as you apply the brakes.
There can be several reasons such as the improper installation of the brake pads, warped disc brakes, damaged rotors, or worn-out brake pads. Brake pads will wear faster than it normally would if the disc brakes are warped. Vibrations Your disc brake needs a check if there are heavy vibrations as you apply the brake.
This vibration can also arise if the rotor is damaged or warped. Your Vehicle. The Science Behind Heat Transfer in Rotors Drill holes and slots in rotors can both improve braking, but under different braking scenarios.
To understand how these rotor modifications can improve stopping power, it is first necessary to understand the three forms of heat transfer: Conduction: When there exists a temperature gradient within a body, heat energy will flow from the region of high temperature to the region of low temperature.
This is conduction. Conduction heat flows from the edge of the rotor through the hub bearing, and it also flows through the brake pad into the caliper. Convection: Air flow dissipates heat from a body. Normally, the higher the air flow over the rotor, the more heat is removed.
The rotor vanes act like a fan blade to move air from the inside of the rotor to the outside edge. The rotor vanes helps remove heat through convection. However, the rotors themselves will be pricey. Plus, with advances in venting, today these rotors are arguably as much about aesthetics as performance, CarThrottle muses.
Especially if you live somewhere where it often rains and ride a motorcycle. Serious track racers, though, prefer slotted rotors over drilled ones, Hot Rod reports. These benefits still translate over to the street. Ultimately, upgrading your brake rotors depends on how you drive. For the vast majority of drivers, solid rotors with vents should suffice.

While drilled rotors have a lot to recommend them, they can wear unevenly and may develop cracks when used in racing vehicles due to the heat and temperature extremes of a race. Drilled brake rotors also tend to wear in concentric grooved styles, which can look funny when the rotors are aged if the drilled hole patterns are not staggered.
While this does not impact the performance of the brake rotors, it can affect the vehicle aesthetic and sensitive drivers may prefer to select a different style of brake rotor or else change out their rotors more often. Drilled rotors are also a poor choice for race cars.
They cannot withstand repeated heat and cool cycles very well, and will fail sooner rather than later as a result. Drilled brake rotors are fine for general use in street vehicles.
Why Choose Slotted Rotors? Slotted rotors work very well for heavy trucks, SUVs, off road vehicles, tow trucks, and competition cars. It is particularly important to choose high quality brake rotors when picking a slotted style. If the brake rotors are not properly machined, from the inner to the outer edges, they can crack sooner than they otherwise would or should. This style of brake rotor delivers improved consistency with every stop, by reducing the friction in the brake pads.
Over the long run the slotted rotors also perform well: As the slots shave down glaze from overheated brake pads, they expose fresh material every time you brake.
As a result, you can rely on these pads to deliver effective braking even in heavy duty vehicles.
