General Benefits of Big Brake Kits
Original Equipment (OE) brake systems do the job they were intended to, stop safely and quietly for the lowest cost possible. After adding performance upgrades, while towing, or just having some fun in the canyons, OE brakes are often overwhelmed by heat when the moment of truth arrives.

Big Brake Kits give your vehicle that super car look and feel, while significantly improving your brake performance in two areas. First, larger brake discs increase heat capacity, meaning your brakes will be more resistant to brake fade. Second, stiffer calipers and brake lines increase pedal feel and modulation.
