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.
However, the holes help by mitigating two factors: heat and stuff getting between the rotor and pads. All of that friction generates a ton of heat, and if the heat can't escape, it degrades the rotor and could warp it. So the holes help it to dissipate somewhat.
Dimpled rotors are brake rotors that have a dimpled cavity. These indentations on the rotor's contact surface, round in nature, allow the brake bad to outgas properly. Its minimal depth doesn't affect the structural integrity of the rotor, thus it's also a great solution for heavier SUV's and trucks.
Drilled, slotted, dimpled or whatever rotors look nice but do not aid in braking. They are fine for 95% of drivers, but aren't really acceptable for track use.
Drilled discs can cool down quicker than standard discs due to the increase in surface area. They also allow for quick expulsion of the gases, meaning you won't experience brake fade as quickly as you would on standard discs.
A perforated brake disc is a highly strained component, which has been structurally weakened.
Whichever they are (though I believe semi-metallic, at the very least for the rears), ceramic pads can be used just fine with your stock rotors. Any pads and rotors will work it's just a matter of how well they will work. There's always going to be friction when the two materials rub together.
For rotors with slots machined in the same direction as the internal cooling vanes, the slots should lean toward the back of the car. For rotors with slots machined in the opposite direction as the internal cooling vanes, the slots should lean toward the front of the car.
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.
Cross-drilled and slotted rotors tend to make some noise when braking. A small, popping noise is normal, as this is the sound of the pad going over the slots/holes (possibly making the noise since it is essentially de-gassing the rotor surface). A squealing sound is not normal unless you have full race brakes.
Pros: If you live in an area that experiences a lot of rain, drilled rotors are a very good 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.
For many drivers, especially those who value high-performance, the choice between ceramic vs. metallic brake pads is easy. Performance-driven drivers prefer the metallic brake pads because they offer improved braking performance in a much wider range of temperatures and conditions.
2 Answers. The fitment front and rear are going to be extremely different. Not only is the diameter and braking surface completely different sizes, the rear disks have a separate machined area inside the hat (the part where it attaches to the hub) which is used for the parking brake. The front one has no such provision
Pay attention to what you feel while driving. One of the most common indicators of worn out brake rotors is rattling, wobbling, or shaking while braking. These vibrations are normally felt through your foot as you apply the brakes, and it is usually indicative of brake rotors that have become warped.

Tested to withstand 400+ hours of salt spray (equivalent to 18 southern Michigan winter months), coated brake rotors edges and vanes stay cleaner longer, optimizing air flow and performance. It is important to note that the coating itself is designed to be worn away in certain areas.
They will stay black (or relatively black) for about the first 100 miles Yeah they come off pretty quickly. It doesn't look so great once the paint or coating comes off. The one car I saw had maybe 300 miles on it, and the rotor looked terrible because it didn't come off evenly.
AutoZone does not turn, resurface, or replaces rotors, brake drums, brake pads, or brake shoes. We confirmed this information with store associates from several AutoZone locations. If you purchase parts and need to return them but have lost your receipt, AutoZone can likely look up your receipt in-store.
O'Reilly Auto Parts offers rotor turning services — also known as rotor resurfacing — at many of its locations. O'Reilly stores do, however, sell replacement rotors, brake drums, brake pads, and other parts needed to maintain and repair your brakes yourself.
You need to turn rotors every time! Regular brake wear and hot spots can often cause your rotors to become warped and having them turned will ensure that they last as long as possible before having to be replaced. If your rotor surface is smooth there is generally no need to have them turned.
Brake rotor unevenness leads to pad wear, and if unchecked, pulsation with high-speed braking. This means the tires wobble and vibrate, leading to a jerky steering column and to anti-lock brake system failure. Replacement of the rotor is critical in this case.
So, how do you know if your vehicle needs new brake rotors? In fact, some manufacturers recommend simply replacing the brake pads themselves without resurfacing or replacing the rotors, as long as the rotors measure more than the minimum thickness and they spin true (are not warped).
As long as you have both front disk brake pads replaced and rotors turned or replaced as well, it should be fine to complete the rear brakes shortly after. Although it is recommended by Ford to replace all four wheel brakes at the same time for safety, your idea should be OK.
Walmart Auto Care Centers don't offer brake services. That means, Walmart does not replace brakes or brake pads. You can, however, purchase brake pads, brake rotors, brake calipers, and/or brake pad and rotor kits from a Walmart store or on Walmart.com and install them yourself.
