Heat is the primary cause of ineffective brakes, due to fading. There is actually a "boundary layer" of gases that builds up between the pad and rotor surface, which inhibits performance. Here's where Power Slot rotors make a big difference. The exclusive Vac-U-Slots machined into the rotor "wipes" the brake pads clean, evacuates gases, and sheds heat. A combination of a "high performance pad" and Power Slot rotors will provide superior reliable braking for virtually all automotive and truck applications, with an upgrade to larger diameter rotors and bigger calipers typically only needed for the most sever competition applications.
Power Slot rotors are manufactured to the highest tolerances keeping safety and quality our number one priority. Slotting, unlike drilling, doesn't compromise the structural integrity of the rotor. When you drill a rotor you weaken it and cause stress points to form that can lead to cracking and ultimately failure. Also, drilled rotors lose considerable surface area compared to slotted rotors, which means less active braking area for pad-to-rotor contact.
