The HPS Performance Brake Master Cylinder Brace Kit dramatically improves brake pedal responsiveness. On a stock vehicle, the firewall and brake booster both flex when pressure is applied to the brake pedal, giving a soft or spongy feeling and reducing the distance the pedal actually travels during braking. This brace counteracts the force from the other side of the firewall to redistribute the pressure and promote a more direct pedal response. The brace is made from 10-gauge steel that is engineered and reinforced to resist flexing under hard braking. It is then powder coated black to provide a strong a durable product that will last. Yellow chromate zinc plated high-strength steel hardware is included to give excellent resistance against rust and corrosion.
