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, our 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.

A combination of Hawk® high performance brake pads and Power Slot slotted rotors will deliver superior, reliable braking for virtually all automotive, truck and SUV applications, even under hard driving and severe duty conditions. But for our most demanding customers such as police pursuit vehicles and club racers, we also suggest Power Slot Cryo rotors

Designed for the performance enthusiast who wants the “look” of a cross drilled brake rotor without the inherent cracking problems, Power Slot’s Pro Stop rotors give you the best of both worlds. Pro Stop rotors are machined with our highly effective Vac-U-Slot design and enhanced with a series of "dimples" that look like drilled holes. As the brake pad contacts the rotor, the dimples turn black, simulating the cross-drilled look.

All Pro Stop rotors are made to the same high quality specifications as the original Power Slot product line, Pro Stop slotted/dimpled rotors are perfect for show cars or for daily driven vehicles. However for high performance or severe duty applications, we recommend our traditional Power Slot slotted brake rotor for maximum effectiveness.
