What advantage do internally vented type rotors provide over solid rotors?

You have a couple of options when it comes to brake rotors. Solid rotors that have a slightly larger surface and offer better durability and stopping power. Vented brake rotors that provide better cooling and are less likely to warp and fade, particularly when heat cycles spike up and down during a competition.

Are vented rotors better than solid rotors?

Vented rotors are a better option than traditional solid rotors. They dissipate heat better and don't warp or fade as much as solid rotors.

What is the purpose of vented rotors?

A vented rotor typically consists of an inner and outer disc connected by ribs in between them. This setup allows them to dissipate heat faster. Since heat is the main culprit behind “brake fade” this is an important feature, and one you'll especially find important for performance models.

What is the main difference between solid and ventilated disc brake rotors?

What's the difference between ventilated and solid discs? Ventilated discs are designed to run cooler than solid discs in normal operating conditions. Most modern trucks have ventilated brake discs but for some off-road and older models, solid discs or rotors are an option.

What are the advantages of a ventilated brake disc?

Ventilated disc brakes are easy to apply, guarantee a safe reduction of speed and can thus avoid accidents or reduce the consequences of accidents. Even after many braking cycles, effectiveness is ensured by the internal ventilation.

Vented Rotors vs. Solid Rotors

What kind of rotors are best?

Drilled and slotted rotors do work particularly well for tow vehicles, trucks, and other cars that carry heavy loads. Heavier vehicles require more energy to come to a stop safely, and this type of brake rotor excels at delivering it. Drilled & slotted brake rotors are also are fine for general use in street vehicles.

Are slotted brake rotors better than solid?

Because they're not drilled all the way through, they resist cracking significantly better. Also, racing brake pads actually need a little heat to be truly effective, Road & Track reports. As a result, if you're seeing a lot of track time, slotted brake rotors are better than drilled or solid ones.

Why are vented discs fitted to some high performance vehicles?

Instead of having just a vent in between the two braking surfaces, these types of discs allow extra air flow around the disc in order to cool it more effectively. These types of discs are usually fitted to heavier and higher performance vehicles to help compensate for the extra heat that is generated through braking.

Are C Hook discs noisy?

Noise-wise, under medium to heavy braking there is a humming type of noise, but I like it, I think it sounds good - each to their own. It's not an unpleasant sound though and under 'normal' braking they're noiseless like plain discs.

What is the advantage of slotted rotors?

Slotted rotor grooves offer two distinct benefits under heavy braking: brake fade, from high-temperature brake pad outgassing, can be significantly reduced, allowing gases to escape through the slots; and the grooves shave off thin layers of brake pad material, reducing glazing and improving braking consistency.

Can you replace vented rotors with solid?

Solid and vented rotors are NOT interchangeable. To switch from one to the other, you may need new calipers, pads, brackets, etc.

Can you put vented rotors on the rear?

Certain vehicle models can have either type, even within the same year. Some can have either solid or vented on the rear wheels. To be certain check out the rotors currently on the vehicle. You'll need to order the same type you find already on your vehicle.

Are vented rotors worth it?

You have a couple of options when it comes to brake rotors. Solid rotors that have a slightly larger surface and offer better durability and stopping power. Vented brake rotors that provide better cooling and are less likely to warp and fade, particularly when heat cycles spike up and down during a competition.

Do performance brake discs make a difference?

Sporting Brake Pads

With high-quality materials, you get improved thermal resistance and better performance in harsh driving conditions. Brake pads and rotors work in sync for their entire life together, making the selection of the right pad very important.

Are slotted discs 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.

Do performance brakes last longer?

Premium brake pads use higher quality materials which typically have lower wear, and therefore a longer service life. Some pads are designed specifically for longer service life and will also wear more evenly than lower quality pads. It is important to pair new pads with new rotors to capitalize on this benefit.

How long do slotted rotors last?

On average, you can expect to replace your slotted and drilled rotors between 25,000 to 35,000 miles.

Do 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.

What should I look for when buying rotors?

Choose cross-drilled and slotted rotors if you're looking for long brake life and good stopping performance in street driving. These rotors do a great job dissipating heat. However, heavily drilled rotors will overheat and experience premature fade under repeatedly aggressive racing conditions.

How do I choose new rotors?

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. The drilled holes give you better cooling for the heat generated by heavy braking, while the slots work to sweep away gas and dust which come through braking.

Are slotted rotors better 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.

Are grooved or drilled discs better?

Drilled holes are even more efficient at heat dissipation than grooves, making it easier for heat to escape. In addition, discs with grooves can provide workshops with a useful indication of wear. “Slots allow direct and immediate control of wear conditions.
