Pad thickness variation measurement is done by hand manually so far and the measurement area is limited like around 10 points depend on the pad size due to the complicate marking and measuring method .
With the circumstance , reliability and accuracy could not be guaranteed against other fields are automated .
Our engineering team is developing Pad Thickness Automatic Measuring System ( PTAMS ).
PTAMS is consist of Universal concept of pad grip and feeding module that adapts various kind of shape and size
of pad and feed to the sensing area. Non-contact type of displacement sensors scan scan full surface of both
friction and back plate side at the same time to measure thickness distribution .
The sensors are mounted on the air bearing slide that enable vibration free movement along with fine flatness
that maintain stable accuracy to be long lasted.
PC based control and data acquisition system enable us to compose scanning widths and mapping conditions for the full surface so that we can investigate full or certain area of wear out ratio or trend freely .
Versatile analyzing software offers historical abrasion trend and 3D image of profile that helps investigating
geometrical variation of friction part and back plate etc.
PTMAS serves hand free , scrip free and enhance accuracy , reliability and investigation .

SeungBok Kim is a CEO at SunBee Instruments.Inc. responsible for conceptual design and management of developing brake NVH-related test equipment. He began to develop test equipment for the brake NVH field based on his knowledge and experiences in sensor applications. Over the last 21 years effort, he launched Static Disc Thickness Variation (DTV) Tester, Dynamic DTV Testers (Dynamometers, Vehicles), Caliper Drag Tester, Drive Axle Drag Tester, Caliper Roll Back Tester, Brake Booster Function Tester. Those products sold out 85 systems and generating several patents. Recently, he completed the development of the "Automatic Pad Thickness Variation (PTV) tester" that is planning to release from this July.
