Which Way Do Drilled and Slotted Rotors Go?

Drilled and slotted rotors come in a variety of sizes to fit most vehicles. They are inserted by drilling a hole then slipping the rotor over it using slots cut into the metal surface. 

The larger holes allow more air and debris to escape, while the smaller ones prevent too much noise from being made when turning your vehicle.

When you get your new car, the dealership will install drilled and slotted rotors on all four wheels. Drilled rotors have a series of small holes in them that allow air to flow freely through them. 

Slotted rotors are similar, but they also have slots cut into them. This allows the brakes to grab hold of the spinning rotor much more easily.

Direction Do Cross Drilled Rotors Go

Rotors can be drilled in one of two directions – clockwise or counterclockwise, depending on their orientation when the rotor was manufactured. 

Slotting a rotor also creates two opposing slots that allow more airflow through the rotor while driving.

When you buy a new car, the mechanic will usually install drilled and slotted rotors. 

This type of rotor has several slots cut into it to improve braking performance. However, over time these slots can become clogged with dust and debris. If this happens, your brakes will not work as well as they should. 

To clean the slots in your drilled and slotted rotors, you’ll need to remove them from the wheel hub and clean them inside and out using a brush or vacuum cleaner. Make sure to dry them completely before reinstalling them on the wheel hub.

If your car has drilled or slotted rotors, you will need to rotate them in the opposite direction of how they were originally installed. 

This is because when the rotor is turned backwards, it grabs onto the tire more effectively and reduces wear on both the rotor and tire.

Rotor nuts tightened too much

It is important to make sure that the rotor nuts are properly tightened so that they do not come loose over time. Over tightening of these bolts can cause damage to the rotor and eventually lead to a breakdown.

Rotors not aligned properly

If your rotors are not properly aligned, it will result in uneven braking performance and excessive wear on the pads or calipers. This issue can be corrected by having your vehicle’s rotors alignment checked by a mechanic.

Calipers not adjusted correctly

Calipers are responsible for ensuring proper brake pad contact at all times during stopping action. If they are incorrectly adjusted, this may cause issues with pedal feel or even squealing brakes when you apply pressure on them.

Brakes worn or damaged

If your brakes have been wearing down over time, they may need to be replaced in order to maintain optimum braking performance in future situations

Benefits of Using Drilled and Slotted Rotors

Drilled and slotted brake rotors are becoming more popular on cars these days because they offer many benefits. Drilled rotors have a series of small holes in them, which allow the brake fluid to flow more freely. 

This means that the brakes will work better when you first apply them and also after being used for a while. 

Slotted rotors don’t have any holes, which makes them less effective at dissipating heat from the braking system but they do tend to last longer than drilled ones.

Reduced Noise

Drilled and slotted brake rotors are much quieter than their counterparts, which makes them a preferred option for those who want to reduce the noise level of their vehicle.

Better Brake Response

The drilled and slotted design results in improved brake response due to better modulation of the braking force. This means that you will be able to stop your car more quickly and with less effort on your part.

Improved Stopping Power

Since drilled and slotted rotor discs can dissipate heat faster, they provide increased stopping power in adverse weather conditions or when the roads are wet.

Longer Life Expectancy

Slots also help reduce corrosion because water cannot easily penetrate into the spaces between the slots and the metal surface of the rotor disc

FAQs

Can You Put Drilled and Slotted Rotors on Backwards?

The answer to this question is no. Drilled and Slotted Rotors work best with a fixed-vented brake system. When they get old, you can resurface them.

Are Drilled Brake Rotors Directional?

Drilled brake rotors are directional, which means that they work better in one direction than the other.

Are Slotted Brake Rotors Better?

Slotted brake rotors are usually used in cars with disc brakes. They are more efficient than traditional brake rotors because they allow the air to circulate around the rotor, reducing heat and noise.

Do Ceramic Brake Pads Ruin Rotors?

Ceramic brake pads are more brittle and can crack or chip when they come into contact with metal. This can lead to the rotor being ruined by the ceramic brake pad.

Are Organic Brake Pads Ok?

Organic brake pads are a popular choice for cyclists who want to avoid the harmful chemicals in conventional brake pads.

Organic brake pads are not only safer but they also last longer than conventional ones.

Conclusion

If your car has drilled and slotted rotors, it is important to replace them at the appropriate time. You should keep in mind that there are different types of drilling patterns available for each brand and style of wheel hub assembly on cars currently on the market today. 

Take note that not all drilling brands are created equal. Rotors can be found in both drilled and slotted designs. Drilled rotors have a hole in the center that allows cool air to circulate around the rotor while braking. 

Slotted rotors are similar, but they have slots on either side of the rotor that allow more heat to escape when braking. 

Which type you choose depends on your car’s brakes and driving style. Both types offer better stopping power and longer life than traditional drums or pads alone, so it is important to make a decision based on your needs as well as your car’s specs.
