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 Stoptech Slotted, Slotted and Drilled, Drilled exclusive slotted brake rotors make a big difference.
Stoptech Slotted, Slotted and Drilled, Drilled 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. For most late model truck and SUV applications andselect sports cars, we also use a special Power Alloy metallurgy and directional cooling vanes to improve high temperature performance.
Stoptech Slotted, Slotted and Drilled, Drilled 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.
