Stop, I SayThe Power Slot Plus is an affordable brake system for Chevrolet, Cadillac, and GMC trucks that uses larger-diameter brake rotors and relocates the factory calipers. The result: The new system acts as a better heat sink under heavy braking during towing and severe-duty conditions. A Vac-U-Slot pattern machined into both sides of the rotor improves cooling and reduces brake fade. Power Slot; 818/709-4800.
