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, the  Vac-U-Slot system helps push water off the braking surface for better stopping power. For most late model truck and SUV applications and select sports cars, Power Slot also uses special Power Alloy metallurgy and directional cooling vanes to improve high temperature performance.
PowerSlot rotors are finished in a durable black e-coat on the hat, edges and internal vanes to prevent corrosion. The braking surfaces are left in a bare iron finish to improve brake pad bed-in.

Power Slot is a division of Centric Parts and part of StopTech. Centric Parts is a leading North American supplier of replacement brake parts and hydraulics for cars, trucks and SUVs. Stoptech is the ultimate balanced big brake kit manufacturer for performance street and racing.
