Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where Power Slot's slotted brake rotors make a big difference.Power Slot's exclusive Vac-U-Slots are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. And in wet, raining conditions, PowerSlot Vac-U-Slot helps push water off the braking surface for better stopping power.The Vac-U-Slot also serves as a visual wear indicator. The slot is machined to the rotor's minimum thickness where it crosses the outside edge. If you cannot see the slot along the outside edge, the rotor has worn down to its discard depth.These several key features make these a great rotor choice for street driving, and open track days!
