Description
Equip your heavy commercial transport fleet with reliable, fade-free braking performance using the genuine-spec Knorr-Bremse Air Disc Brake Pad Set (OE K127928K50). Engineered specifically for high-load air disc brake systems, this comprehensive wholesale pad set utilizes advanced heavy-duty friction materials that deliver exceptional stopping power across demanding highway and vocational routes. Worn brake pads, glazing, and substandard friction compounds severely compromise braking efficiency, leading to dangerous stopping distances and increased rotor wear. This professional-grade brake pad set solves those issues directly. It utilizes heavy-duty non-asbestos friction formulas, precise backing plate dimensions, and integrated thermal insulation layers to provide consistent pedal bite, minimize rotor scoring, and maximize service life for heavy commercial fleets.
Technical Parameters
| Category | Specifications & Technical Details |
| Exact OE Part Number K127928K50 Specification | We manufacture this brake pad set strictly to the Knorr-Bremse OEM K127928K50 technical standard. As a result, the steel backing plate dimensions, locating pin holes, and slot tolerances match the original caliper 100%. |
| High-Performance Copper-Free Eco Friction Formula | We adopt a new-generation heavy-duty copper-free eco friction material. Consequently, it maintains a stable friction coefficient (0.38–0.45 μ) under extreme conditions from -40°C to +800°C. Moreover, it completely eliminates thermal fade. |
| Dual-Layer Thermal Insulation & Shear-Resistant Backing Plate | We equip the pad with a high-strength heavy-duty steel backing plate and composite insulation underlayer. As a result, it effectively blocks heat transfer to the caliper piston and brake fluid. Meanwhile, it prevents vapor lock and piston seal failure. |
| Low-Rotor-Wear & Low-Dust Composite Design | We optimize the friction block hardness ratio and microcrystalline structure. Therefore, this design extends brake disc service life while greatly reducing black dust accumulation during driving. |
| Bulk Wholesale Packaging & Batch Traceability | We design this packaging specifically for global truck repair shops, fleet operators, and bulk parts distributors. Additionally, we use moisture-proof, shock-resistant industrial bulk packaging. Notably, each set carries a complete batch anti-counterfeit traceability code. |
Applicable Car Brands & Models
Each complete axle set (K127928K50) includes four heavy-duty disc brake pads (for left and right wheels), high-strength stainless steel retaining springs, pad mounting clips, and necessary slide pins or bolts where specified by the OE kit design.
Heavy commercial brake pads typically require inspection every 50,000 kilometers and replacement when friction material thickness reaches the minimum safety limit of 2 to 3 millimeters, depending heavily on route topography and cargo loads.
Yes, absolutely. The friction compound is specifically engineered to balance high stopping performance with gentle rotor interaction, preventing deep scoring and extending overall wheel-end lifecycle.
Yes. We offer flexible tiered wholesale pricing and secure moisture-resistant industrial pallet packaging for global fleet operators, commercial truck workshops, and heavy-duty parts distributors.
