GeoMetric™ Brake and Wheel End Components

Higher grade steels, reinforced welding, tighter tolerances and denser frictions are just a few of the characteristics that are found in our GeoMetric™ product line, which includes ceramic new-lined shoes, OE-grade mill-balanced brake drums, precision-milled S-cams, automatic slack adjusters and more. Our product improvements translate into longer product life and less maintenance for quality-conscious fleets.

The Importance of Brake Geometry

Throughout the wheel end, engineers have designed components to work at optimum angles to one another. The brake shoe must sit squarely on the spider, creating an even foundation from which the webs must sit at a 90-degree angle to the drum face. Similarly, for proper torque from the air chamber to the slack adjuster, there should be a 90-degree angle from the slack adjuster arm to the air chamber push rod, when cutting the rod. These optimum angles are referred to as "brake geometry." They were designed and engineered into the braking system by Original Equipment Manufacturers, but brake geometry is often overlooked in the specification of aftermarket brake and wheel end parts.

The SilverbackHD GeoMetric™ Series

SilverbackHD introduced its line of GeoMetric™ brake and wheel-end components to support brake geometry from the shoe to the brake hardware, to the S-cam, cam repair kit, slack adjuster and air chamber.

The SilverbackHD GeoMetric™ new-lined brake shoe is built with reinforced welding and harmonized heat-treating on the anchor and cam ends, so it supports brake geometry where inferior new shoes or used relined shoes fail. Our shoe ensures that SilverbackHD customers receive an even wearing of friction. Uneven shoe wear can result in disproportionate heat load buildup in the wheel end, which increases fleet maintenance costs.

But the shoe alone does not solve brake geometry issues. Inferior brake hardware compromises brake geometry with flat-spotting cam rollers, hanging return springs and worn anchor pins. That’s why SilverbackHD designed its GeoMetric™ Series brake hardware to harmonize with the GeoMetric™ brake shoe under the company’s Intentional Engineering™ protocol. By matching engineering specifications of hardness on the shoe’s cam ends and the cam rollers as well as the head of GeoMetric™ Series S-cams, Intentional Engineering™ eliminates costly repairs.

When fleets are looking to do something different to control costs and maintain a competitive edge, restoring OE brake geometry with the SilverbackHD GeoMetric™ Series of intentionally engineered brake and wheel-end components will improve vehicle brake performance and safety, all while lowering cost per mile.
