Solid and vented rotors made with gray cast iron are the most common types of rotors. Drilled and slotted rotors are a variation of the same design. A solid brake rotor is just that – solid. There is no space between the two friction surfaces. A vented brake rotor more commonly has a space between the two friction surfaces of the rotor. This helps with cooling and is more common on the front of the vehicle because front brakes do 70-80% of the braking and endure the most heat.

Unlike slotted or drilled faced rotors, general stock replacement rotors are normally solid faced rotors that are either solid or vented. When replacing a rotor, there should be little confusion as to whether you need a vented rotor or not. If your car came with a vented brake rotor, then the replacement part will be a vented brake rotor. If the car came with a solid brake rotor, the replacement part is a solid brake rotor. No solid rotor replacements are available for a vehicle that came originally equipped with a vented rotor.

Slotted and drilled rotors are a performance modification that do not increase braking power, but might aid in the cooling of the rotors in high heat situations. There are both advantages and disadvantages to having slotted or drilled rotors. One rule of thumb is that if you are just daily driving, there is no reason to get slotted or drilled rotors other than to improve the way your rotors and wheels look. (Drilled and slotted rotors can have an aesthetic appeal to them because they may have a rust prevention measure applied to them and can be indicative of a performance braking system.) One disadvantage of drilled rotors is that they will provide more friction against your pads and reduce the life of them. Another disadvantage is the potential for a drilled brake rotor to crack when subjected to thermal stress. A drilled hole can upset the grain structure of the metal; the result is an uneven temper in the metal. As the brake rotor cools, the uneven temper can cause cracks. The most common crack seen is located from the outer most drilled hole to the edge of the brake rotor. Since the edge of the brake rotor is the first to cool, this is where the most uneven area of cooling occurs. For this reason, drilled rotors are not well suited to racing conditions in which high brake component temperatures are always occurring. Cracks cause vibrations and the larger the crack the more dangerous. The advantages are that the scrub friction of the holes and slots, while increasing the wear on your pad, reduce the chance of the pads becoming glazed.

Slotted and drilled rotors have a series of slotted channels, drilled holes, or both. These rotors primary purpose is to reduce the effects of brake fade. When the temperature is too hot for the pad and rotor to work properly together, brake fade occurs, which refers to the reduced feeling of brake power. The high temperature causes the brake pads and rotors to release a gas, thus reducing the friction that they would provide at lower temperatures. The slots and drilled holes are a means to dissipate this gas and reduce brake fade. The drilled rotors may even help cool the braking system; however, the drilled holes may encourage the temperature related fractures previously mentioned. Of course, when you are experiencing brake fade, you are punishing your rotors to the point that you could warp or crack them regardless of whether or not they are slotted or drilled.

Weve all noted at some point or another that a particular thing is the best invention since that of the wheel. Or perhaps weve laughed as someone has tried to make a simple process unnecessarily difficult for themselves by reinventing the wheel. Though man had made and implemented a wide variety of tools before the invention of this one, the wheel has assumed an iconic place in the way we look at the world. And unlike many historic inventions which, though important at the time of their genesis, have since fallen by the wayside, the wheel continues to remain an important part of our lives today, forming an essential linchpin upon which one of the most important tools of modern life is built.

These days, it is easy to take for granted the great mobility we enjoy, choosing as we do from a multitude of ways to travel. One of the most frequently used methods of transport remains the car, from its humble beginnings as a self propelled vehicle in the eighteenth century to the vast array of shapes and makes we find today. Like several other modes of transit, the principle of the car is based upon that of the wheel, which, combined with an axle, allows for the forward motion that is such an intrinsic part of the human condition.

As has occurred with other elements of the car, a combination of technology and a preference for the finer things in life has resulted in a choice of wheels and tyres that is quite astounding. Different types of tyres have created greater diversity in the terrains upon which cars may be used, and made use of increased technological knowledge to ensure the safety of a cars passengers. Meanwhile, such accessories as hubcaps have been added to this important car part to personalize them to both car manufacturer and the driver.

While historians cannot agree entirely upon the exact point at which this important tool was invented, there is little doubt that this remains unimportant to todays modern motorist. We rarely give our wheels a second thought, but without them, our cars would be entirely useless, and we would be left sitting on the road, in a pointless metal cage.

Car stereo systems are the most important components of any car audio. In the recent days, more and more people are realizing that a car stereo system is not good enough when it does not please your liking. With many upgrades from the first car stereo system in 1930, the options available to choose from today are amazing. You might have a system that is flat and without an extra spark that can pull you into the pleasures of good music. You are probably used to having a system that does not even do a job good enough decorating your car. New age car stereo systems have been designed to ensure that dull reception of audio is a thing of the past. You therefore need to think seriously about what you need to do to upgrade your system.

If you need to improve your sound, speakers are stocked in varieties. They are affordable and usually upgraded every now and then. Just by replacing them, you will improve the sound of your car stereo system drastically. If you use broken speakers, you definitely need replacements. Your system may be perfectly in the right functioning capacity and your replacements will enhance the sounds. If you want to improve on the quality of your sound with increased volumes, you need to get amplifiers. They make sure sound is delivered without being distorted on high volumes. They are widely available and affordable. Amplifiers come in many ranges and they are there for your asking and convenience.

Vibration damping materials make sure your noise levels do not get out of control. You can view some of the noise reducers on sites that have the information. They are affordable and will go a long way in ensuring your interior sounds are controlled. Subwoofers come in handy to make sure you feel the beat. They work to enhance sounds and produce great bass balances that will leave you asking for more music. They can be mounted under seats and in your cargo area. Therefore it will be good to ask for vehicle specific subwoofers. They also come in various varieties one being, component subwoofers which are very easy to install. You really have so much storage space even after installing them. So go ahead and get them.

You must put into consideration your music style because it determines the kind of car stereo systems you will get. The systems can be bought from legal audio stores and online stores. They come with so much product information and you do not have to wonder about a product you wish to get. Sites of online stores provide forums for discussions about products and also share consumer reviews to gain credibility. They also deal with a variety of brands. A quick search for the brands history will empower you to know which brands are more trusted. They must come with high quality and features that will please you. Finally, you need to consider the price. The bottom line is to get a car stereo system that will be fair and fitting to your budget. There is so much to learn about car stereo systems and when the process is over you know you will take to your car a much better system.
