The Brake caliper assemb is a comprehensive service kit for the front disc brake caliper of HOWO 4X2 tractor trucks. This complete assembly includes all critical sliding and fastening components to restore caliper performance and ensure reliable braking.
The Brake caliper assemb consists of the Sliding pin protection sleeve compression ring, Sliding pin protection sleeve, Sliding pin bushing, and Hexalobular socket head cap screws. Each part is precision-engineered to work together, providing smooth caliper movement and consistent pad application.
When you choose authentic howo Parts, you receive a Brake caliper assemb that meets all OEM specifications. This kit is designed to eliminate caliper sticking, reduce brake noise, and extend pad life, ensuring your vehicle stops safely and predictably.
The Brake caliper assemb is a direct replacement for worn or corroded caliper hardware. With this kit, you restore factory-fresh caliper function, improving braking performance and reducing maintenance costs.
The Sliding pin protection sleeve compression ring is a resilient sealing element that fits over the sliding pin boot. It creates a tight barrier against dirt and moisture, preventing corrosion and ensuring smooth pin movement. This ring is made from durable elastomer that maintains its shape under repeated compression.
Proper function of this compression ring is essential for long caliper life. It keeps the sliding pin protection sleeve securely in place, preserving the lubrication inside and blocking contaminants that could cause pad drag or uneven wear.
The Sliding pin protection sleeve is a flexible boot that covers the caliper sliding pin. It protects the pin from road debris, salt, and moisture, maintaining a clean, lubricated surface for smooth caliper movement. The sleeve is manufactured from high-grade rubber or silicone that resists cracking and aging.
This sleeve works together with the compression ring to create a sealed environment. A damaged or worn sleeve can lead to pin seizure, causing uneven pad wear and reduced braking efficiency. Replacing it as part of the Brake caliper assemb restores proper protection and caliper function.
The Sliding pin bushing is a precision-machined sleeve that fits inside the caliper bracket or anchor. It provides a low-friction bearing surface for the sliding pin, allowing smooth axial movement while minimizing play. The bushing is typically made from bronze or high-performance polymer that resists wear and corrosion.
Worn bushings cause the caliper to bind or tilt, leading to uneven pad contact and reduced braking performance. Replacing them with new units as part of the Brake caliper assemb ensures proper alignment and consistent clamping force, extending the life of both pads and disc.
The Hexalobular socket head cap screws are high-strength fasteners used to secure the caliper bracket or the caliper halves. Their six-lobe drive provides excellent torque transfer and reduces the risk of stripping, making them ideal for critical brake applications. These screws are heat-treated to achieve the required property class.
These screws are supplied in the correct length and thread pitch for the HOWO 4X2 caliper. Using the proper fasteners is essential for maintaining the structural integrity of the Brake caliper assemb and ensuring safe braking operation. They resist loosening under vibration and provide consistent clamping force.

The Brake caliper assemb replaces worn bushings, sleeves, and rings that cause caliper sticking. With new components, the caliper slides freely, ensuring even pad wear, reduced drag, and consistent braking performance.
Every component in this Brake caliper assemb is manufactured to original equipment standards. The elastomers resist heat and aging, the bushings are machined for exact fit, and the fasteners meet strict strength requirements.
The Brake caliper assemb includes all necessary hardware: compression rings, sleeves, bushings, and screws. You get everything for a full caliper service in one box, simplifying ordering and reducing workshop downtime.
This Brake caliper assemb fits all HOWO 4X2 disc brake calipers. Backed by our global distribution and technical team, you can trust that you are getting the right parts with expert support.
The Brake caliper assemb is designed to address the most common failure points in disc brake calipers: stuck sliding pins, worn bushings, and degraded protective boots. By replacing these wear items, the caliper regains its ability to self-center and apply even pressure to the brake pads. This not only improves braking performance but also reduces the risk of pulsation and noise.
The Sliding pin protection sleeve and compression ring work as a system to keep grease in and contaminants out. The sleeve’s bellows design accommodates the pin’s axial movement without cracking, while the compression ring ensures a tight seal at the base. The bushing provides a low-friction bearing surface that reduces the force needed to slide the caliper, improving pedal feel and modulation.
The Hexalobular socket head cap screws are chosen for their high strength and resistance to stripping. Their drive design allows for higher torque transfer, making it easier to achieve the correct clamping force without damaging the fastener. This is especially important in brake applications where vibration and thermal cycling are constant.
Every component of the Brake caliper assemb is inspected for dimensional accuracy and material integrity. The elastomeric parts are tested for hardness, tensile strength, and resistance to brake fluid and heat. The bushings are measured for inner and outer diameters to ensure a perfect fit with the sliding pin and caliper bracket.
We also perform functional tests on sample assemblies, simulating caliper movement under load to verify smooth operation and sealing effectiveness. Fasteners are torque-tested to confirm they meet the specified property class. These rigorous checks guarantee that the Brake caliper assemb delivers reliable performance in real-world conditions.
With decades of experience in brake component manufacturing, we have developed a quality system that consistently produces parts that exceed OEM expectations. The Brake caliper assemb is a testament to our commitment to safety and durability.
Regular replacement of caliper hardware with the Brake caliper assemb prevents costly failures such as pad seizure, disc scoring, and uneven wear. By proactively servicing the caliper, you extend the life of brake pads and discs, reducing overall maintenance expenses.
For fleet operators, this kit simplifies inventory management. Instead of stocking individual bushings, sleeves, rings, and screws separately, you can keep a single part number for the complete service kit. This reduces the risk of missing parts during repairs and speeds up the service process.
Improved caliper function also leads to more consistent brake application, which enhances driver confidence and reduces stopping distances. The reduction in brake drag can slightly improve fuel economy, as the wheels spin more freely. These tangible benefits make the Brake caliper assemb a smart investment for any trucking operation.
The Brake caliper assemb is designed for straightforward installation with basic hand tools. The sliding pin components are pre-sized to match the HOWO 4X2 caliper, so no modification or adaptation is needed. The compression ring and sleeve slide easily over the pin, and the bushing presses into the bracket with light pressure.
The Hexalobular socket head cap screws are supplied with the correct thread and length, eliminating the need to source separate fasteners. A simple torque wrench is sufficient to achieve the recommended clamping force, and the screws are designed to resist stripping even under repeated tightening.
For workshops, this kit reduces the time spent on caliper servicing. The logical grouping of parts and clear labeling (if present) make the job quicker and less error-prone. This translates to faster turnaround times and higher customer satisfaction.
Each Brake caliper assemb is accompanied by a detailed installation guide that includes torque specifications, lubrication recommendations, and step-by-step procedures. This ensures that even less experienced technicians can perform the service correctly.
Our technical support team is available to assist with any questions regarding the Brake caliper assemb, from compatibility verification to troubleshooting installation issues. We also offer online resources such as video tutorials and FAQs to help workshops achieve optimal results.
With the Brake caliper assemb, you not only get high-quality hardware but also the backing of a dedicated support network, ensuring that your brake system remains safe and reliable over the long term.
