Chevy’s RPO, or regular production order, options all have an alphanumeric code. Many since 1963 have begun with the letter Z. The letter doesn’t mean or stand for anything, and it has been used for hundreds of options over the decades, both big and small, as have most of the alphabet and many numbers.
Why do rotors warp?
The brake rotors withstand a lot of heat during the process of braking, and need to dissipate this heat quickly so that the brake pads will be able to be pressed down again. Because of this mass amount of heat, the surface of the brake rotors can become uneven over time, which is often referred to as warping.
Why does my truck shake at high speeds?

What happens if the wheels lock up when braking?
When brakes lock up, the vehicle may veer sharply to the left or right, and the back end may fishtail causing the driver to lose control [source: Car Talk]. If this happens while you’re driving, pump the brakes consistently until you come to a complete stop, and get the car to a mechanic as soon as possible.
