Constructed for severe-service haulage trucks, multi-axle trailers, low-bed transporters, and intermodal freight chassis, these Brake Linings WVA 19760 offer a high-endurance wheel-end friction overhaul solution. Engineered to match 420 x 200mm commercial foundation drum brake shoes, this non-asbestos friction block set provides high deceleration torque, excellent thermal fade recovery, and steady drum contact during continuous heavy-payload service.
Ensuring reliable stopping power and stable directional braking under severe axle load cycles demands friction compounds that withstand extreme thermal fatigue. Heavy payload transfers, downhill grade retarding, and constant urban traffic braking generate intense drum temperatures, where low-grade friction segments undergo rapid material loss, glazing, and uneven contact wear.Our Brake Linings WVA 19760 deliver tight OEM dimensional tolerances and heavy-duty structural reliability for professional fleet overhaul programs.
Dense Semi-Metallic Friction Blend
Manufactured from an advanced eco-formulated low-metallic matrix, each 19760 lining block undergoes high-tonnage thermal compression molding followed by computer-regulated baking. This process yields a stable friction coefficient across working ranges reaching 750°F (400°C), preventing fade and ensuring instant torque delivery during critical stopping events.
Precision Mounting Geometry & Drum Protection
Each segment comes with factory-machined rivet pockets calibrated to standard commercial 420 x 200mm shoe tables. This design secures high shear resistance and vibration absorption against extreme pneumatic application force. The non-aggressive compound formulation promotes smooth contact across the brake drum face, minimizing scoring, heat spotting, and uneven lining taper.
Key Features & Specifications
Target Foundation Fitment: Purpose-built for commercial transport axles utilizing standard WVA 19760 brake shoe tables on 420 x 200mm drum configurations.
High-Torque Friction Compound: Low-metallic non-asbestos material ensures consistent braking response, low dusting, and high thermal stability under heavy gross loads.
Heat Fade Resistance: Post-cured composition maintains braking torque under elevated operating temperatures up to 750°F (400°C).
Accurately Positioned Rivet Holes: Factory-drilled counterbore holes guarantee alignment and secure mechanical bonding onto bare shoe steel.
Extended Drum Life: Non-abrasive friction composition reduces drum micro-cracking, grooving, and edge taper wear.
Frequently Asked Questions (FAQ)
Q1: Which vehicle and axle platforms use these Brake Linings WVA 19760?
A: These friction blocks are engineered for heavy-duty freight trucks, lowboys, container chassis, and multi-axle commercial trailers equipped with 420 x 200mm foundation drum brakes.
Q2: What are the primary dimensions for the WVA 19760 lining set?
A: The WVA 19760 profile is designed for 420mm inner drum diameter assemblies fitted with 200mm wide commercial brake shoe tables.
Q3: Are rivet holes pre-machined into the lining segments?
A: Yes. All 19760 blocks arrive pre-drilled and chamfered according to standard industrial hole patterns for immediate fastening onto steel shoe frames.
Q4: How does this friction material handle steep mountain descents and prolonged braking?
A: Through a specialized high-temperature post-curing process, the compound resists surface crystallization and thermal fade, maintaining predictable deceleration under heavy thermal stress.
Q5: Are private labeling and bulk export palletization available?
A: Yes. As a direct factory manufacturer, we offer custom edge-code stamping, branded box packaging, and seaworthy pallet loading for commercial parts distributors and fleet suppliers.
