SilverbackHD GeoMetric Series Brake Hardware Maintains Brake Geometry For Better Brake, Drum Performance
Brake geometry, the alignment of the brake to the spider, cam and drum, is essential for proper braking efficiency. Yet many brake hardware kits use inferior parts that result in flat spotting cam rollers, rusted and worn out anchor pins, and malfunctioning return springs that cause brake drag. The result is poor brake performance, reduced safety, and a higher cost per mile.
SilverbackHD GeoMetric Series brake hardware uses our Intentional Engineering® to focus on the trouble spots that most compromise brake efficiency and safety.
This hardware is intentionally engineered to harmonize with SilverbackHD GeoMetric new-lined brake shoes.
Fortified Return Springs: All SilverbackHD Geometric return springs are service cycle tested to at least 300,000 cycles (double the aftermarket standard). While some manufacturers use decades old standards for cycle testing that result in brake drag on today’s demanding road conditions, SilverbackHD Geometrics use Intentional Engineering® to make sure your brakes are properly returning and not burning friction and drum with every revolution of the wheel.
And because brake frictions are now thicker and shoes are now wider than before, the return spring often has to carry a heavier load. So, you can count on the GeoMetric Series brake hardware to be built with 50% more tensile strength.
SilverbackHD engineers have also determined that broken return spring hooks are a leading cause of premature failure in the industry. But you can count on every SilverbackHD GeoMetric return spring to come with heat treated return springs for longer life.
Intentionally Engineered Cam Rollers: The true alignment of shoes to drum is negotiated by the cam roller. Uneven wear that causes cam roller flat spotting will also cause uneven friction wear.
To maintain rolling functionality of the cam roller, SilverbackHD uses a wide pattern knurling. This dual purpose knurling allows the S-Cam to efficiently grab the roller and keep it turning, while the knurls are spaced far enough apart not to allow road sediments to clog the cam roller.
SilverbackHD GeoMetric cam rollers are heat treated in a proprietary two step process that guarantees they have a uniform SRC60 Rockwell hardness. This Intentional Engineering® specification matches the S-Cam head hardness on all SilverbackHD GeoMetric Series S-Cams, as well as the heat-treating on all SilverbackHD GeoMetric new lined brake shoes.
Improved Anchor Pins and Bushings: Frequent replacement of the anchor pins and bushings is essential to proper brake geometry. But inferior pins and bushings often rust and make it nearly impossible to remove without expensive labor or possible damage to the spider.
SilverbackHD GeoMetric Series bushings are heat treated to a SRC60 Rockwell hardness. This improvement slows erosion from the brake and spider that can cause brake walk and throw off brake geometry. SilverbackHD also uses high quality stainless steel bushings with every anchor pin and bushing combination to reduce corrosion. The result is an easier change of pins and bushings for better brake geometry.
OE-grade Corrosion Resistance: All SilverbackHD GeoMetric Series hardware components are Intentionally Engineered® to exceed the industry’s highest standards of corrosion resistance. All springs are powder coated to withstand 1,000 hours of salt spray corrosion protection. Gold zinc dichromate plating (five times more corrosion resistant than white zinc) is used on all cam rollers, while anchor pins are also zinc plated. The plating process ensures resistance than lower quality coating processes. Finally corrosion resistant stainless steel is used on our anchor pin bushings.
So when you need better braking, safer stopping and a lower cost per mile, choose SilverbackHD, because at SilverbackHD Products “HD” means “Heavier Duty.”
