Premium 42431-87305 Truck Brake Drum For Daihatsu Delta Rear Axle Brake

Product Specification

Premium Brake Drum 42431-87305 for Daihatsu Delta | High-Performance Rear Axle Brake Component

Product Overview

The 42431-87305 Brake Drum is a precision-engineered replacement component designed specifically for Daihatsu Delta series light and medium-duty trucks. As a critical part of the vehicle’s drum brake system, it is manufactured to ensure consistent braking force and high structural stability under various load conditions.

Constructed from high-grade G3000 / HT250 grey cast iron, our 42431-87305 model is optimized for exceptional thermal storage and rapid heat dissipation. This helps prevent "brake fade" and surface cracking during frequent stopping or while navigating steep descents. Each drum is CNC-machined to exacting tolerances, providing a seamless fit and OEM-matching reliability for fleet maintenance and vehicle restoration.

Key Benefits

Superior Thermal Stability: Engineered to handle high temperatures, reducing the risk of thermal cracking and maintaining a stable friction coefficient.

Precision Dynamic Balancing: Each drum undergoes factory balancing to eliminate vibrations, which protects your wheel bearings and ensures smooth braking.

Perfect Fitment (OEM Standards): CNC machining ensures the drum matches original dimensions for easy installation without modification.

High Wear Resistance: Advanced metallurgy ensures a long service life, reducing the frequency of maintenance and overall fleet operating costs.

Anti-Corrosion Surface: (Optional) Treated with a protective finish to prevent oxidation during storage and sea freight transportation.

Frequently Asked Questions (FAQ)

1. Is the 42431-87305 Brake Drum compatible with the Daihatsu Delta?

Yes, the 42431-87305 Brake Drum is a high-quality OEM-spec replacement specifically designed for the Daihatsu Delta (V57, V116 series) and certain Toyota Dyna or Hino 300 models. It is engineered to match the exact 6-hole bolt pattern and internal diameter of the original equipment. We recommend verifying your vehicle's VIN or the pilot hole diameter to ensure a 100% perfect fit before installation.

2. What material grade is used for the 42431-87305 to prevent brake fade?

Our 42431-87305 brake drums are manufactured using premium G3000 Grey Cast Iron. This high-carbon material is chosen for its superior thermal heat capacity and cooling properties. For light trucks frequently carrying heavy loads, this ensures that heat is dissipated quickly, preventing brake fade and ensuring consistent stopping power during frequent "stop-and-go" city driving.

3. Does this brake drum require additional balancing before use?

No, every 42431-87305 unit is dynamically balanced at the factory to eliminate centrifugal imbalances. Proper balancing is critical to prevent steering wheel vibration and "pedal pulsation." By installing a pre-balanced drum, you also extend the service life of your wheel bearings and tires, significantly reducing the total maintenance cost of your vehicle.

4. What is the "Maximum Diameter" limit for the 42431-87305?

Safety is paramount. Every 42431-87305 drum has a Maximum Diameter (Max Dia) limit stamped on its exterior. During routine brake shoe inspections, if you find the internal diameter has worn down to this limit, the drum must be replaced. Using a drum beyond its safety limit increases the risk of the casting cracking or failing under emergency braking pressure.
