The Thor Tool brake check device is designed to allow one person to measure brake travel within 1/100th of an inch. To use the device, a mechanic or driver chalks the wheels, releases the parking brakes and attaches the magnetized tool to each brake chamber. By pushing the brake pedal, accurate brake adjustment readings are displayed on easy-to-read digital gauges. The device is made from hardened stainless steel and plastic.
