10 inch Brake Drum include Ford, Holden, Landcruiser, Landrover, Jeep, F Series
A drum brake is a device that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum.
Caravans and campers use 10-inch electric brake hub drums on all trailers over 750kg.
Couplemate manufactures Australian-made brake drums to suit electric brakes for the caravan and R.V. markets.
What makes Couplemate Brake Drum Different?
Couplemate engineers discovered a problem with imported caravan drums called porosity. Porosity is a significant cause of braking inefficiencies.
Porosity is a series of holes or air bubbles in a steel casting that causes lower brake shoe adhesion.
In simple terms, a porous surface will have less braking resistance than a non-porous surface.
How to remove Periosity from Brake Drums
Shaking or vibrating the tooling containing a hot drum casting effectively removes air bubbles, thereby significantly reducing porosity.
Further, during the machining process, craftsmen look for signs of porosity.
Porous drums are rejected, scraped, and returned to the furnace.
Couplemate drums pass rigorous testing and inspection processes during manufacturing.
How to calculate Stud P.C.D.
Braking is achieved when a brake controller activates the electric magnets enabling the magnets to attach to the brake drum.
As a result of magnet attachment, the backing plate brake shoes engage on the drum surface, causing braking.
Brake drum failure occurs via magnet damage to the drum magnet face.
Couplemate Trailer Parts manufactures high-quality trailer brakes and drums.
