Power Train Parts/Dry Disc Brakes

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized dry disc brakes within our power train parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and braking configurations, ensuring that every component meets rigorous Komatsu standards for deceleration control and preventive maintenance:
• Machine & Heavy-Duty Dry Disc Braking System Compatibility: Engineered for a broad range of Komatsu heavy-duty wheel loaders and motor graders, our products ensure exact material strength ratings, dimensional tolerances, and structural interface definitions for a 100% perfect match, rapid replacement, and factory-grade performance.
• Complete Heavy-Duty Dry Disc Brake Range: 1. Brake Discs & Rotors: Designed with superior cooling fin structures and thermal-crack resistance to withstand high-frequency sudden braking thermal shocks; 2. Brake Calipers & High-Temperature Pads: Formulated to provide high friction coefficients and resist thermal fade under continuous heavy-duty braking; 3. Caliper Pistons, Master Cylinders & Seal Kits: Ensuring flexible caliper piston movement while blocking external mud and debris ingress for reliable hydraulic control.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu dry disc brake parts alongside rigorous high-performance aftermarket alternatives featuring reinforced heat-resistant friction formulas, delivering exceptional operational reliability and extended service lifespan at a cost-effective procurement point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global dry disc braking component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and repair facilities.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of tens of brake discs, calipers, and friction pads matching Komatsu mainstream wheel loaders and motor graders. Backed by barcode-enabled intelligent warehousing and Komatsu cross-reference databases, we guarantee precise matching and immediate dispatch upon order confirmation to fulfill routine maintenance and rapid replenishment needs for overseas fleet workshops and minimize equipment downtime caused by brake disc cracking or pad glazing halting complete machine operations.
• Anti-Rust Sealing and Moisture-Proof Packaging: We implement specialized industrial packaging standards for precision friction planar surfaces, mounting holes, and caliper piston rods of all brake discs and brake pads utilizing heavy-duty long-lasting anti-rust oils and independent moisture-proof vacuum plastic sealing bags, while high-density anti-collision pearl cotton and wooden separation strips between large brake discs ensure zero metal oxidation or moisture absorption during transcontinental ocean freight under salt spray and high humidity environments.
• Heavy-Duty Crated Protection: Bulk heavy-duty brake disc and caliper assembly shipments are packed in high-strength export fumigated wooden crates with custom anti-vibration timber blocks and high-strength bolts suspending heavy units off the container floor to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without deformation.
• Consolidated Sourcing for Dry Disc Brake Overhaul Kits: We support overseas clients by consolidating large brake discs alongside matching full sets of high-strength brake pads, caliper piston seal rings, guide pins, and high-temperature brake fluids into precise bundled full-set dry disc brake maintenance kits, achieving a one-stop purchasing model that pairs braking system service supplies while significantly reducing comprehensive logistics costs for overseas workshops.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities for asset health monitoring reliability.
• Application-Specific Dry Disc Durability Solutions: We address extreme jobsite challenges—such as high-drop rock quarries and high-frequency transfer motor grader operations—where original brake discs develop surface thermal cracking from continuous high-temperature emergency braking, accompanied by premature friction pad wear. We also provide professional engineering upgrades utilizing high-carbon alloy steel, optimized ventilation cooling fin structures, and semi-metallic high-wear-resistant heavy-duty brake discs and pads.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like high-frequency steering wheel or body vibrations during light braking, extended braking distances, or caliper oil leaks. This focuses on two critical protocols: 1. Runout Measurement & Guide Pin Maintenance: Technicians must use dial indicators to check that brake disc runout stays within Komatsu limits, and thoroughly clean caliper guide pins while applying specialized high-temperature grease during every pad replacement to prevent uneven wear from sliding restrictions; 2. Minimum Thickness Replacement Safety: Service technicians must replace brake discs entirely when disc thickness drops below specified minimum limits, strictly prohibiting continued machining to prevent structural fracture during high-speed braking.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including dry disc system disassembly diagrams, caliper mounting bolt torque standards, hydraulic line bleeding specifications, and visual guides, assisting overseas technical personnel in executing standardized construction.
