Function, Specifications, Materials, and Key Parameters of AZ4007443020 Right Brake Caliper Assembly

1. Function

• Braking Force Application: The AZ4007443020 right brake caliper assembly converts hydraulic pressure into mechanical clamping force to slow or stop the vehicle, acting as a critical component of the disc brake system.

• Heat Management: Designed to dissipate heat generated during braking, ensuring consistent performance and preventing brake fade under high-load conditions.

• Structural Integrity: Provides a rigid mounting point for brake pads and pistons, ensuring precise alignment and efficient braking.

2. Specifications

• Part Number: AZ4007443020

• Installation Location: Right-hand side of the vehicle's disc brake system (passenger's side in most markets).

• Compatibility: Engineered for heavy-duty commercial vehicles, such as those equipped with Sinotruk HOWO or similar engine systems.

• Brake Type: Hydraulic disc brake caliper assembly.

3. Materials

• Caliper Body:

• Cast Iron or Aluminum Alloy: Cast iron offers superior strength and heat dissipation, while aluminum may be used for lighter-duty applications to reduce weight.

• Pistons:

• Steel or Phenolic Resin: Steel pistons provide durability and heat resistance, while phenolic resin pistons reduce heat transfer to the brake fluid.

• Seals and Dust Boots:

• Rubber or Elastomer: Ensures hydraulic fluid retention and prevents contaminant ingress.

4. Key Parameters

• Piston Diameter: Typically ranges from 40 mm to 60 mm (varies by application), determining the clamping force applied to the brake pads.

• Brake Pad Interface:

• Pad Area: Optimized for the vehicle's weight and braking requirements.

• Pad Retention: Features clips or pins to secure brake pads in place.

• Hydraulic Ports:

• Number and Size: Typically two ports (inlet and outlet) with standard thread sizes (e.g., M10 x 1.0) for brake line connection.

• Mounting Points:

• Bolt Pattern: Designed to fit specific vehicle mounting brackets (e.g., 4-bolt or 6-bolt patterns).

• Weight: Approximately 5–15 kg (varies by material and design).

• Operating Temperature Range: -40°C to +150°C (or -40°F to +302°F), ensuring reliability in extreme conditions.

Additional Notes

• Maintenance: Requires periodic inspection of seals, pistons, and brake pads for wear or damage.

• Replacement: Should be replaced with OEM or equivalent parts to ensure proper braking performance and safety.

• Compliance: Meets or exceeds industry standards for braking systems (e.g., SAE, DIN, or ISO).

The AZ4007443020 right brake caliper assembly is engineered for durability, efficiency, and safety, making it a critical component in heavy-duty commercial vehicle braking systems.
