Power Slot Slotted Brake Rotor Sets

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. 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. Power Slot uses a special Power Alloy metallurgy and directional cooling vanes to improve high temperature performance.

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. 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.
