Brake pad measuring tool and method of using the same
First Claim
1. An apparatus for measuring the thickness of a disc brake pad installed on a vehicle with suspension components without requiring removal of a corresponding wheel comprising:
- a housing having a distal end comprising a longitudinal cut-away portion, the distal end being sized and shaped to extend pass suspension components or through an opening defined through the corresponding wheel for positioning relative to a brake rotor disc corresponding to the disc brake pad;
a probe telescopically disposed in the housing, the probe being arranged and configured to contact a backing plate corresponding to the brake pad;
a calibration barrel coupled to the probe;
a spring coupled to the probe for urging the probe proximally against the backing plate when taking a measurement of the thickness of a disc brake pad; and
a measuring barrel coupled to the probe so that when a measurement is made the measuring barrel is moved a distance equal to proximal movement of the probe relative to the distal end of the housing.

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 32nd of 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.

12. A method of measuring the thickness of a disc brake pad of a vehicle with suspension components without requiring removal of a corresponding wheel comprising:
-
providing a distal end of a measuring apparatus, which distal end is sized and shaped to extend by the suspension components or through an opening defined through the corresponding wheel; placing the distal end of the apparatus against a corresponding brake rotor of a vehicle; releasing a probe from the distal end of the apparatus; moving the probe proximally until it comes into contact with a corresponding backing plate of the brake pad; moving a measuring barrel proximally approximately the same distance as the probe moved; and reading a distance measurement of the movement of the measuring barrel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
