Product Introduction

This Brake Shoe Lining WG4075450160 is an OEM heavy-duty friction lining exclusively designed for commercial vehicle drum brake systems. Crafted from a premium asbestos-free composite friction material and precision-molded to match Sinotruk’s original specifications, it is engineered to deliver stable, wear-resistant braking performance for heavy-load transportation, construction machinery, and long-haul operations.

Performance

• Asbestos-Free High-Performance Friction Material: Formulated with a copper-free ceramic composite blend, it maintains a stable friction coefficient (0.35-0.45) across extreme temperatures (-40℃ to 600℃), eliminating brake fade during continuous heavy braking.

• Precision-Drilled Mounting Design: The 8-hole positioning layout is CNC-machined to exact tolerances, ensuring a secure, non-shifting bond with the brake shoe base plate and uniform force distribution under load.

• Enhanced Wear Resistance: The reinforced fiber matrix structure reduces lining wear rate by 25% compared to standard materials, extending service life and lowering maintenance frequency for fleets.

Core Function

1. Acts as the core friction component of the drum brake system, cooperating with the brake drum to convert the vehicle’s kinetic energy into thermal energy, realizing reliable deceleration and emergency braking—a critical safety part of heavy duty truck brake parts.

2. Maintains consistent friction performance under heavy loads, frequent braking, and harsh road conditions, ensuring driving safety on long downhill sections and construction sites.

3. Ensures a tight, stable fit with the brake shoe, preventing delamination or displacement during high-intensity braking.

Frequently Asked Questions – Brake Shoe Lining WG4075450160 Sinotruk

1. What friction material is used in this brake shoe lining?

This lining uses a non-asbestos organic (NAO) composite formula. It blends aramid fibers, mineral fillers, and phenolic resin binders to achieve a stable friction coefficient between 0.35 and 0.45 — even under sustained high-temperature braking conditions. In other words, it stops heavy loads consistently without fading.

2. Is the Brake Shoe Lining WG4075450160 a direct fit for Sinotruk HOWO trucks?

Absolutely. This part is precision-molded to match the exact dimensional and mounting specifications of the original Sinotruk WG4075450160 lining. It drops directly onto compatible brake shoe assemblies without any drilling, trimming, or modification required.

3. How long does this brake lining typically last under normal operating conditions?

Service life depends on load weight, driving habits, terrain, and maintenance practices. However, under standard heavy-duty highway conditions, this lining typically delivers 60,000–100,000 km of reliable service before reaching minimum thickness. Frequent mountain descents or overloading will naturally shorten this interval.

4. Can I use this lining on non-Sinotruk trucks that share similar drum brake dimensions?

While the WG4075450160 is engineered specifically for Sinotruk platforms, some Chinese heavy-truck brands share similar brake architectures. We recommend verifying the exact lining dimensions (length, width, thickness, and rivet hole pattern) against your target application before cross-fitting. Our technical team can assist with cross-reference verification — simply contact us with your vehicle details.

5. Does this brake shoe lining comply with environmental and safety regulations?

Yes. The asbestos-free formulation complies with international environmental health standards, including EU REACH restrictions on hazardous substances. The manufacturing process follows ISO 9001 quality management protocols, and the product references ECE R90 performance benchmarks for replacement brake linings.

6. What is the recommended storage condition for this friction lining?

Store in a cool, dry environment away from direct sunlight, moisture, and chemical solvents. Keep the linings in their original packaging until installation to prevent surface contamination that could affect initial bedding-in performance. Properly stored, these linings maintain full performance characteristics for up to 5 years.
