Yes, slotted drilled rotors will eat pads faster than a standard rotor but they do dissipate heat a lot faster for better braking. What is the advantage of drilled and slotted rotors? The design of drilled and slotted rotors offer drivers the advantages of both designs with minimal side effects.
Full Answer
What are drilled drilled rotors and are they better?
Drilled-slotted rotor design offers the driver an advantage with a few side effects. Furthermore, the holes drilled provide a better cooling effect from the heat being produced by heavy braking; on the other hand, the slot helps in sweeping away gas as well as dust, which comes from braking.
What is the advantage of larger diameter rotors?
Following that heat transfer logic tells us that a rotor with more mass can absorb more heat energy than a lighter rotor of the same design. That is an advantage of larger diameter rotors, along with the greater leverage of increased size.
Why are drilled and slotted rotors bad for your bike?
This opposite effect is having an adverse impact on the rotor as well. Since this design features less metal contact, the disc tends to heat up quickly compared to a solid rotor; due to this effect, you cannot use a drilled and slotted rotor in a high-performance setting.
How do drilled slotted rotors wear?
The wearing process occurs in a grooved cycle. Unlike other rotors out there, the drilled-slotted rotors often wear in a concentric cycle; this means that you might start receiving vibration in your steering over an extended period as your rotor ages or the hole pattern is not correctly staggered.

Do drilled rotors last longer?
They tend to be the longest lasting overall, while also produce very little dust and are quiet to operate. It is precisely the plain nature of these brake rotors that makes them last longer: Without any drill holes or slots there is little room for cracks to develop.Mar 27, 2019
Do rotors with holes wear pads faster?
However, just driving normally, drilled and slotted rotors may wear pads slightly faster, especially if new rotors have and burrs or inconsistencies that would gouge the pad surface, though that's not really a problem that you should have to deal with unless you're talking about the cheapest import rotors you can buy.
Are drilled brake rotors better?
Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.
How long do brake pads last with drilled and slotted rotors?
between 25,000 to 35,000 milesOn average, you can expect to replace your slotted and drilled rotors between 25,000 to 35,000 miles.Mar 25, 2021
Do drilled and slotted rotors make noise?
When braking, cross-drilled and slotted rotors tend to make noise. A small popping noise is normal, as this is the sound of the pad going over the slots/holes. Unless you have full race brakes, a squealing sound is not normal.
Do you need special brake pads for drilled and slotted rotors?
Ceramic pads work fine on cross drill slotted rotors. Metallic pads will work just as well, up to a point. Ceramic pads tend to last longer than metallic pads and score the rotors less. Under extreme braking conditions, a ceramic pad will dissipate heat and cool down faster than a metallic pad.Oct 7, 2013
Are drilled rotors good for daily driving?
DRILLED rotors are better for your daily driving because they are less prone to warping or getting high spots and they are usually easier on brake pads, but they do not perform as well under extreme braking as Slotted.Mar 31, 2011
Should brake rotors be smooth?
Over time, your rotors will also wear down and you may find the pads have created a slight groove in the rotor. This is very harmful to the rotor and this must be avoided. A healthy brake rotor will be a smooth and uninterrupted surface, free of dust, grooves and grit.Feb 16, 2012

Are drilled and slotted rotors worth the money?
Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.
Are drilled and slotted rotors good for towing?
After-market drilled and or slotted rotors (like these from Power Slot and Brembo) are more expensive, louder, dustier, and require specialized maintenance than OEM rotors. But they also perform better during heavy towing and hauling.Feb 11, 2009
Are dimpled rotors better than drilled?
The dimpled rotor is an evolution of the cross-drilled rotor designed for track and sport cars. Because SUV's and trucks exert a much higher load and stress on the brake rotors, the dimpled rotor is recommended due to the higher stress handling capacity.
Why do rotors wear unevenly?
This means that the rotors will start wearing unevenly sometimes as you use the braking system , and one single area of your rotor receives contact more often. This issue is usually common among high performing vehicles; sometimes, cracks tend to develop as a result of heat and the extreme area they often encounter. When using your cars for constant stops at highway speed, you might as well encounter this problem.
Why use slotted rotors?
One of its most significant advantages is that it aids in getting rid of brake dust away from your braking pads. When debris concentration between the pad and the rotor is reduced, it creates more surface area for the pad and the rotor to come into contact; this means that you will achieve a better grip and a better stop. Furthermore, coefficient friction is significantly increased; this allows you to use less energy each time you apply pressure on your braking system. This means that you can bring your car to a stop much faster with the safety effort. It is due to this reason that most motorsports like the NASCAR tend to advocate for their use on race cars.
What is a blank rotor?
Also referred to as smooth, blank is a rotor with a smooth or a plain surface; there are no marking or holes on the metal. The drilled only and slotted only rotors tend to have significant differences, which are combined in the drilled and slotted rotors to help boost their functionality significantly.
Why do rotors have holes?
The holes help in boosting friction efficiency between the pad and disc significantly.
Why do brake pads start glazing?
Usually, when you consistently apply on your brake, the friction generated between your pad and the rotor will lead to surface glazing.
What are rotors used for?
Also referred to as discs, rotors offer a contact point for the car’s brake pad once you engage your car’s pedal in order to come to a stop when driving. Once you apply pressure on your pedal, every pad’s set caliper housing gets activated, which then compresses them into a rotor hence creating friction. This process will then help reduce your car’s forward momentum allowing you to stop when necessary.
Why do my brakes make a noise?
There is no doubt that all brakes tend to create a screeching sound as the pads start wearing down; this is often due to metal and metal contact.
What is a drilled rotor?
Drilled rotors are based on the solid rotor style and have a pattern of strategically placed holes drilled into the contact surface to achieve improved cooling, gas and dust expulsion, and overall performance. When your brake pads contact the rotor surface, heat is generated and a pocket of hot air is formed between the surfaces as a result.
Why are rotors vented?
Most vehicles on the road today are sold with solid, blank rotors installed from the factory. At most, the rotors are vented to allow for better heat dissipation. In high performance vehicles like the E63 AMG, BMW M4, and others, the stock front brakes are either cross drilled, slotted, or both. Often, people will upgrade their stock solid brake ...
Why do slotted rotors have vanes?
Instead of holes, slotted rotors have vanes machined into their surfaces. The premise behind this feature is similar to drilled rotors as it's intended to help vent brake dust and heated air away from the surface of the rotor to allow for improved cooling.
Why are brake pads cooler?
When your brake pads contact the rotor surface, heat is generated and a pocket of hot air is formed between the surfaces as a result. The drilled holes allow this pocket of heated air, dust, and gas to escape through the vents within the rotor and out, resulting in cooler brakes.
Is a slotted rotor stronger than a drilled rotor?
Additionally, slotted rotors are stronger and less prone to cracking compared to drilled rotors as the structural integrity of the slotted rotors is not compromised during the machining process. People have pointed out that slotted rotors tend to eat pads faster than solid or drilled rotors.
Why use ceramic brake pads?
This allows the ceramic pads to handle high brake temperatures with less heat fade, provide faster recovery after the stop, and generate less dust and wear on both the pads and rotors. "The ingredients in ceramic compounds produce a light-colored dust that is much less noticeable and less likely to stick to the wheels.
Is ceramic brake pad quiet?
Noise-Level: Ceramic brake pads are very quiet, creating little-to-no extra sound when the brakes are applied. Temperature & Driving Conditions: Compared to organic brake pads, ceramic brake pads can be more reliable in a wider range of temperatures and driving conditions.
Do ceramic brake pads prevent warping?
TOM: As far as we know, however, ceramic pads do not prevent warping. If you misuse or overheat your brakes, rotors will still warp. It's possible that the improved heat-dissipation qualities of the ceramic pads may help prevent warping to some degree, but you're not going to be immune from warped rotors.
Do ceramic brake pads damage rotors?
Because they are soft, ceramic pads do not damage rotors and provide smooth, even friction during braking. Ceramic pads are also clean and produce less dust as they wear down. They also wear down slowly and provide good heat transfer away from the rotor.
Why do you need cross drilled rotors?
Crossed drilled rotors and slotted rotors (and rotors that are both slotted and drilled) are designed to allow gases to escape that build up between the brake pad and brake rotor. This allows your brakes to run cooler and stop better.
How long do slotted rotors last?
Beside above, how long do slotted rotors last? 30,000 to 70,000 miles
Do slotted rotors last longer?
They will not last as long as you'd like them to and will not give you much more performance than just the slotted ones will. The slotted rotors will provide space for allowing brake dust and such to be brought away from the pad, which keeps it clean and better intact with the rotor.
Why do brake pads wear faster?
One of the main roles of the pad is to absorb heat, but materials like ceramic and copper that are found in some ceramic brake pads can’t absorb much heat as they should. The unabsorbed heat is transferred to other parts of the braking system, causing them to wear and tear faster.
What is a ceramic brake pad?
A ceramic brake pad is made of a mixture of filler materials (like copper) and ceramic fibers. As of this combination, ceramic brake pads are quieter.
What is the impact of brake action?
The Impact of the Braking Action- The key to brake wear is in understanding how braking works. When you push down on your brakes, your vehicle’s kinetic energy converts into heat and sound that dissipates from the system, making the car stop.
Is ceramic brake pad good for racing?
The bottom line is ceramic brake pads are very durable but they wear rotors faster than other types of brake pads. Mechanics said that ceramic is best not used in cold climates and for racing.
How do you remove a broken rotor screw?
To efficiently remove broken rotor bolts or screws, you can just go in with a new 3/8 inch drill bit and get it done. You do not have to push hard, so the jack stands is actually not an issue. The screw heads commonly rust to the rotor, not to the threads rusting to the hub, but a significant force is indeed required to get them loose.
Why do they drill holes in rotors?
The holes are meant to primarily help to dissipate heat away from the rotor, while the stuff between the pads and the rotor acts like the threads on a tire so that when water splashes on the rotor and you hit the brakes, the water is more easily pushed out of the way, instead of getting trapped between the brake pad and its disc.
Are drilled rotors bad?
No, they are certainly not. In fact, should you be given the option of choosing between drilled and slotted rotors, the drilled ones will give you better braking efficiency than the slots on either normal city or even highway driving.
What happens if you put slotted rotors on backward?
First, there is no such thing as driving backward or forwards with either drilled or slotted rotors. It is therefore just a matter of individual preferences. If on the other hand, you have the curve going towards the back of the car, it is an excellent braking system.
Do drilled rotors wear pads faster?
Both drilled and slotted rotors have a kind of cheese grater effect on the brake pads. This simply means that every component wears out faster. Certainly, therefore, slotted and/or slotted rotors wear out brake pads faster than most standard rotors, but they do dissipate heat a lot faster too, for a better and improved braking efficiency.
Do slotted rotors make noise?
Yes, they do. Both the slotted and drilled rotors are known to make a kind of ‘ticking’ noise just like cards in bicycle spokes due to the presence of air apparently. This noise is more audible when beside a median, and it is quite normal with either slotted or drilled rotors, which of course depends on their build.
Is there a difference between left and right rotors?
No, there isn’t much difference really. The stock rotors are not much difference between the left or the right. In both of them, the vent blades are straight from either the inside or the outside. Similarly, in both these rotors, their fins are equally angled. (Read Also: Is it okay to replace only one brake rotor?Find Out)
