ABSTRACT:
A brake pad measuring device is designed to be small enough to fit through various suspension components or many vehicles' wheel aperture and still maintain the ability to move in three-dimensions. The device is compact enough so that it may take an accurate reading of the thickness of a brake pad while being between the caliper housing and the brake pad backing plate of a vehicle. The device also comprises a spring so that once it is correctly placed, it may be manipulated in order to automatically get a reading of the thickness of a brake pad to the closest millimeter or 32ndof an inch by releasing the spring to cause a measurement to be automatically taken. Using this device, any user can get quick, reliable measurements for all four sets of brake pads in a matter of minutes and all without having to remove a single wheel from the vehicle.
