In 2002, the pccb (porsche ceramic composite brake) option got you slotted rotors. Even some racers in the honda challenge admit they did not improve their lap times with slotted or drilled rotors and still elect to use blanks.
Performance Brake Upgrade Kits for Sport, Utility and
As mentioned above, you should strongly consider the type of rotor you need.
Are drilled and slotted rotors good for everyday driving. However, for track racing (high speed stops), slotted rotors are the better choice. They perform well in rainy climates by offering a good “wet bite,” hold up well over the life of the rotors, and deliver more friction and more bite than their slotted counterparts. All that extra work on the rotor is not for looks though.
This is why high end bmw, porsche, corvette, and mercedes rotors are drilled, not slotted. They don't last as long (ie crack) and are hard on pads. This is not necessary for daily driving because when you slam on your brakes, its usually once and hard.
I understood that just resurfacing is not 100% solving the problem, but seem like a cheaper alternative. Plain/smooth brake rotors are typically less expensive than drilled or slotted rotors. I don't see why you'd need slotted or cross drilled for everyday driving.
Finally, the drilled and slotted brake rotor is a combination of drill patterns and slot patterns. Now, pccb gets you cross drilled rotors once again. Unfortunately, the drilled and slotted brake rotors are also not suitable for extreme driving.
I can tell you that the slotted rotors have a unique flutter feel when you are at anything approaching full tilt (greater than 1 g braking) and the slots are hard on the pads greatly affecting pad life ($$$). The cross drills help the rotor and pad cool off, while the slots are primarily focused on pad health. The most popular designs in aftermarket rotors are drilled and slotted.
Drilled rotors have holes drilled into them and look to provide improved brake cooling, similar to slotted rotors. There are numerous designs of rotors present in the market today for vehicles including; Also, what if we just resurface and change break pads?
Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. As you might imagine by the name, drilled brake rotors have been drilled to create a series of holes on their surface. These rotors have drilled holes and machined grooves cut in the braking surfaces where the pad makes contact.
It's all about dispersing heat and gasses, when it comes to these drilled and slotted rotors. Let's take a look at these two design types and figure out what are the optimal brake rotors for your car. If all you are changing are the rotors, then the only performance increase you might see is less brake fade, and maybe improved brake response depending on the material of the rotors.
Slotted rotors help keep the pad from glazing under high heat but the kind of high heat we are talking about won't be seen on the street unless you ride your brakes down a mountain (which you really shouldn't do). Drilled, blanks, slotted, and drilled. But under normal conditions it makes no difference.
Some drilled rotors also feature a slotted design. Do you recommend replacing stock blank rotors rather than fancy drilled or slotted rotors? So for everyday driving on a sedan with squeaking noise and vibrations when breaking:
Tips for buying and using brake. On the flip side you can get cheap regular rotors and they won't last as long either. They too perform well in the rain.
Plain/smooth rotors are commonly quieter than slotted or drilled rotors and wear very well. Drilled rotors offer advantages for everyday drivers that will make a difference on the road. 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.
I pay the extra to get the good stuff because i don't want to find out my bargin rotor/pads was the reason i plowed into a car in front of me. Drilled rotors are for weight reduction and looks. The cross drilled slotted vented discs that your referring to make a huge difference.
Plain/smooth brake rotors have the most frictional surface area (no holes or slots) and are often more effective in actual braking power. They also allow water to escape the brake’s surface better, which can lead to. On the street, however, the temperatures your brakes encounter never.
If you live in an area that experiences a lot of rain, drilled rotors are a very good choice. They offer the benefits of both types of rotors. I think modern brake pad technology has surpassed alot of the need for these types of rotors.
Therefore, drilled rotors are definitely not to be used in race cars. But for everyday driving they are either a waste or for looks. Not many people have had this experience i hope.
'drilled' disc rotors 'drilled' disc rotors are definitely a step ahead of slotted ones when it comes to high performance driving. They crack easily at the drill points under heavy use so they aren't used on track.
