Humidity is the worst enemy of every car. Humidity causes mold, rust, rot, engine failure and brakes and pressure plates to seize. Eventually humidity will destroy any car. This 1969 Shelby GT500 in all original condition demonstrates what WILL happen to your brakes if your car is left in a garage with too much humidity. The front brakes are frozen solid from rust and corrosion caused by the humid air. A close-up shot through the wheel shows surface rust that has formed on the rotor and caliper. In a humid garage, this rust will form anywhere there is a bare metal surface including cylinder walls, the flex plate, rotors, and calipers. This rust can and eventually will seize a motor, brake system and clutch.
