Power Stop Cross-Drilled, Slotted Rotors and Cross-Drilled & Slotted

Power Stop cross-drilled or slotted rotors both offer certain advantages depending on the user's vehicle, driving style and individual needs.

Both styles will provide cooler brake temperatures as a result of dissipating the gasses burning off the brake pads. This "de-gassing" or "out-gassing" will keep the pads in contact with the rotor resulting in less brake fade after repeated stops. The lower temperatures will also promote longer rotor and pad life under equal driving conditions. Improved "bite" on the brake pads will also enhance brake performance from each option. Both types of Power Stop rotors will promote improved wet weather braking as water is swept between the pad and rotor. Either cross-drilled or slotted rotors, combined with our Axxis Metal Master or 9-1-1 Extreme Performance brake pads, will out perform a stock brake system under normal and "spirited" street driving conditions.

Cross-drilling of the rotors allows air to flow through the rotor, cooling the rotor material and the pad from the extreme heat generated by high speed panic stops...a brake component's worst enemy. Users in law enforcement, emergency health care and municipalities report reduced rotor warping, increased pad and rotor life, superior braking performance, faster stops with less fade, and improved wet-weather braking.

Some enthusiasts prefer slots because they feel the rotor maintains a higher level of structural integrity as opposed to drilling the same rotor. This is a valid argument, though only in the severest applications will the integrity of a cross-drilled rotor become an issue. Of more importance is the original OE design of the rotor. Cross-drilling or slotting an OE design rotor is an excellent upgrade in terms of increased performance at a reasonable cost. But if users are experiencing problems with unusual warping or cracking of a slotted or cross-drilled rotor, they should consider a larger brake upgrade to meet their specific demands.

The major trade off for the extra integrity of a slotted rotor is shorter life. When slotting, only the rotor surface is machined. As the slot passes under the pad, it provides an area for the gasses burning off the pad to expand into and dissipate, keeping the pad in contact with the rotor. As the rotor wears, so will the slot, providing less area for gas expansion. When a rotor wears, there is less mass to absorb heat, which might make a slotted rotor more prone to warping as it reaches it's minimum thickness dimensions.

A cross-drilled rotor will provide an escape path for the gasses over the entire life of the rotor. This is especially beneficial as the rotor gets thinner near the end of its usable life. This benefit is true of a vented rotor, as the gasses escape out of the rotor's internal air vanes, and also of a solid rotor, as the gases will always have a space to expand into.

Regardless of choice between cross-drilled or slotted rotors, all are:

• mill balanced to prevent vibration
  
• ground finish eliminates runout and taper
  
• double disc grinding ensures parallelism leaving a perfect, non-directional finish
  
• plated for protection against the elements
