This Caliper Assembly is the ideal choice for operators who demand reliable and consistent braking performance.
Whether you are performing a routine brake service or rebuilding a worn caliper, this Caliper Assembly kit delivers factory-quality components and a straightforward installation. Each part is precision-crafted to meet the highest standards of quality and durability, ensuring that your Sitrak C7H braking system operates at peak efficiency.
This protective cover seals the long sliding pin opening in The part, preventing dirt, moisture, and debris from entering the pin bore. Made from durable rubber with a metal insert, it provides a positive seal while allowing smooth pin movement. In The part, this cover is essential for maintaining the integrity of the sliding mechanism, ensuring consistent brake pad wear and reliable braking performance.
These high-strength socket head cap screws are used to secure various components within the Caliper Assembly. Manufactured from grade 10.9 alloy steel with a zinc-nickel coating, they provide exceptional clamping force and corrosion resistance. Two sizes are included in the kit: one for securing the long sliding pin side and another for the short sliding pin side, ensuring a precise fit for each mounting point in the Caliper Assembly.
The Long Sliding Pin is a critical component of the Caliper Assembly, guiding the caliper movement and ensuring even pad application. It is precision-ground from high-strength steel with a wear-resistant coating, providing a smooth, low-friction surface for the caliper to slide on. In the Caliper Assembly, this pin is designed to withstand the high temperatures and forces generated during braking, ensuring consistent performance and long service life.
The Sliding Pin Bushing provides a low-friction bearing surface for the sliding pins in the Caliper Assembly. Made from high-grade bronze with a self-lubricating property, it ensures smooth and consistent caliper movement while resisting wear and corrosion. In the Caliper Assembly, three bushings are included to ensure full support and alignment of the sliding pins, contributing to even brake pad wear and optimal braking performance.
The Sliding Pin Protective Boot is a flexible rubber cover that seals the sliding pin and bushing area from contaminants. In the Caliper Assembly, it prevents dirt and moisture from entering the sliding mechanism, maintaining smooth operation and preventing corrosion. Two boots are included, one for each sliding pin, ensuring comprehensive protection of the Caliper Assembly components.
This press ring secures the protective boot to the caliper housing. In the Caliper Assembly, it is made of spring steel with a corrosion-resistant coating, providing a tight, reliable fit that keeps the boot in place and ensures a positive seal against contaminants. Two press rings are included, matching the two protective boots in the Caliper Assembly.
The Transmission and Adjusting Mechanism is the heart of the Caliper Assembly, converting the braking force into clamping action and automatically adjusting for pad wear. This left-side mechanism features a precision gear train and a self-adjusting screw that compensates for pad wear, maintaining consistent brake pedal feel and stopping power. In the Caliper Assembly, this component ensures optimal braking performance throughout the life of the brake pads.
The Carrier is the structural mounting bracket of the Caliper Assembly, securing the caliper to the axle and providing a rigid mounting point for the brake pads. Made from high-strength ductile iron with a precision-machined surface, it ensures accurate alignment of the caliper with the brake disc. In the Caliper Assembly, the carrier is designed to withstand the high forces of braking, providing a stable and durable foundation for the entire caliper system.
The Short Sliding Pin is the counterpart to the long sliding pin, guiding the caliper on the opposite side. In the Caliper Assembly, it is manufactured from the same high-strength steel with a precision-ground finish and a wear-resistant coating. Together with the long pin, it ensures smooth, even caliper movement, contributing to balanced pad wear and consistent braking performance.
This protective cover seals the short sliding pin opening in the Caliper Assembly, providing the same level of protection as the long side cover. Made from the same durable rubber material with a metal insert, it prevents dirt and moisture ingress, ensuring smooth pin movement. In the Caliper Assembly, this cover is essential for maintaining the reliability and longevity of the sliding mechanism.
The Caliper Assembly is engineered with precision-machined components that ensure even pad pressure and smooth caliper movement. This results in consistent braking performance, reduced brake fade, and improved safety, making it an essential component for reliable vehicle operation.
This Caliper Assembly kit includes every component needed for a full caliper rebuild – pins, bushings, boots, covers, adjusting mechanisms, and fasteners. No additional parts are required, saving time and ensuring compatibility.
All components of the Caliper Assembly are manufactured from high-grade materials with advanced coatings to resist corrosion, wear, and high temperatures. This ensures long service life and reduced maintenance costs, making it a reliable choice for heavy-duty trucking.
The Caliper Assembly is manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H. The precision-machined components and correctly sized fasteners ensure a hassle-free installation, reducing downtime and labor costs.
