Disc Master, Inc. was founded by Shawn Kohan in the early spring of 1991 in Chicago, Illinois as a full line supplier of Drums & Rotors.

Since the company's conception, Disc Master, Inc. has seen many changes. Internal change as a result of incredible sales growth, numerous capital improvement and operational expansion projects, to external factors like changes in the international supply chain structure, world economy, and product portability. Disc Master, Inc. has continued to adapt in terms of product availability, program offerings, and service, as necessary to meet the needs of the customer.

Although these changes have continued to sculpture the face of the company over the years, one thing has remained constant "Disc Master's mission, a mission that strongly reflects the commitment to the customer, and which is the lifeblood of the company's success. Simply put, "Disc Master, Inc.'s mission is to provide superior products and service, at a minimal cost to its customers". This initiative has never wavered. The company's quest to become the premier provider of quality brake products has propelled Disc Master into a position as a global supplier of a full range of brake related products.

Today, Disc Master's product offering includes a full line of Drum & Rotors, as well as disc brake pads. All product manufacturing is supported by the prestigious ISO/TS16949 certification, by TÜV Rhineland, Germany. Thus, ensuring that Disc Master products are manufactured to the highest level of sustainable quality, using only the best metallurgical and machining processes available worldwide.

All castings start using the highest available grade of base materials, focusing on composition, tensile strength and hardness. All finished goods are made to meet or exceed OEM G3000 (SAE J431) standards. The addition of alloy elements, such as chromium and copper, provide maximum life effectiveness and enduring product strength. Additionally, precisely machined concentric bearing cups are used to reduce bearing abrasion and to prevent rotor wobble. Applications with wheel studs, bearings and ABS rings are all manufactured to O.E. specifications, and where specified by O.E, heat dams are included to help insulate the bearing area from excessive heat.

State of the art CNC machining equipment with FUNAC and Mitsubishi software ensure that the following tolerances are met on each and every drum and rotor produced:
  • Ultra smooth surface, which meets O.E. specifications of 15-80 RMS.
  • Thickness variation held within .0005"
  • Lateral run out held to a maximum of .004"
  • Surface flatness to within .002"
  • Parallel braking surfaces held to within .0001"

In addition, all rotors and drums are rolled-edged marked, offering complete product traceability. Precision balancing assures vibration and worry free performance. Direct from the box technology offers ready to install products, which do not require additional localized machining. Ultra-fine non-directional finishing provides smoother pedal feel and trouble free operation after the installation. Further, the cornerstone of the Disc Master program has always been the company's unparalleled support before, during, and after the sale. This tradition has allowed the company to continually achieve its mission, and has supported the successful growth initiatives of its customers.
