Engineered for Class 7–8 commercial haulers, multi-axle freight carriers, lowboys, and container chassis running 410 x 220mm foundation drum assemblies, these Brake Linings WVA 19940 provide an extra-wide friction renewal package. Tailored specifically to standard 19940 profile foundation brake shoes, this low-metallic non-asbestos friction block set provides balanced pneumatic braking torque, superior resistance to high-temperature fade, and uniform drum wear across demanding line-haul corridors.
Maintaining predictable deceleration control, balanced directional stability, and strict compliance with commercial fleet safety standards under heavy gross axle weights requires wheel-end friction materials that withstand sustained mechanical and thermal fatigue. Continuous highway freight transit, heavy port drayage, and prolonged downhill mountain descents generate intense friction heat, where substandard lining blocks suffer accelerated thickness decay, surface glazing, and aggressive drum grooving.Our Brake Linings WVA 19940 deliver genuine OEM-level dimensional accuracy and heavy-duty structural durability tailored for professional fleet maintenance operations.
High-Density Non-Asbestos Friction Compound
Formulated with an advanced low-metallic, non-asbestos matrix, each 19940 friction segment undergoes high-pressure hydraulic molding followed by controlled thermal post-curing. This resilient formulation maintains a stable, uniform friction coefficient across severe operating temperatures up to 750°F (400°C), preventing high-temperature brake fade and ensuring immediate pedal modulation during critical heavy-load deceleration.
Precision Hole Pattern & Drum-Friendly Wear Profile
Every lining block is manufactured with factory-drilled, chamfered rivet holes that align accurately with standard 410 x 220mm commercial brake shoe steel skeletons. This ensures maximum mechanical shear resistance and vibration stability under severe braking torque spikes. The smooth friction matrix encourages uniform contact across extra-wide commercial brake drums, significantly mitigating localized hot spots, drum grooving, and edge taper wear.
Key Features & Specifications

Frequently Asked Questions (FAQ)
Q1: Which axle types and vehicle configurations are compatible with these Brake Linings WVA 19940?
A: These friction blocks are engineered for commercial haulers, flatbeds, lowboys, and container chassis equipped with 410 x 220mm foundation drum brakes (such as European-style wide trailer running gear and specialized vocational setups).
Q2: What is the primary dimensional specification for the WVA 19940 lining profile?
A: The WVA 19940 profile is specifically engineered for 410mm diameter commercial brake drums utilizing wide 220mm brake shoe tables (410 x 220mm).
Q3: Are the rivet holes factory pre-drilled in the lining blocks?
A: Yes. All 19940 lining segments arrive precision-drilled and counterbored to match industry standard rivet layouts for immediate mechanical fastening onto bare steel shoe cores.
Q4: How do these linings perform under sustained downhill braking and high-temperature conditions?
A: The friction material undergoes a specialized thermal post-curing process to prevent glazing and brake fade, ensuring rapid heat dissipation and reliable torque recovery under heavy braking cycles.
Q5: Can you provide customized packaging, edge-code stamping, and palletized bulk shipping?
A: Yes. As a direct manufacturing source, we provide custom part-number edge printing, private-brand packaging boxes, and export-grade pallet packaging tailored for commercial parts distributors and fleet suppliers.
