•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

• Commercial Vehicle-Optimized Quiet Braking Engineering:

Specifically engineered for commercial vehicle front-axle applications where braking noise and vibration directly impact driver comfort, concentration, and long-haul fatigue, this quiet brake disc incorporates advanced NVH (Noise, Vibration, and Harshness) reduction technology throughout its design. The high-carbon gray iron composition provides inherent vibration-dampening characteristics that absorb and dissipate the high-frequency oscillations responsible for brake squeal and chatter, while the precision-ground friction surface ensures uniform, smooth pad engagement across the entire contact area. For commercial drivers who spend extended hours behind the wheel, this reduction in brake noise contributes to a less fatiguing, more comfortable cabin environment — particularly important during urban delivery routes with frequent stop-and-go driving.

• Frequent Start-Stop Durability for Commercial Operations:

Designed to withstand the repeated, cyclical braking demands characteristic of commercial vehicle operations — including urban delivery, shuttle services, municipal fleets, and last-mile logistics — this 289.6mm front brake disc is engineered for exceptional durability under high-frequency braking cycles. The robust G3000 and GG15HC high-carbon gray iron formulation resists thermal fatigue, surface hardening, and uneven wear patterns that can develop when discs are subjected to dozens or hundreds of brake applications per day. This extended service life reduces replacement frequency, lowers maintenance costs, and minimizes vehicle downtime for fleet operators and commercial users.

• Compact Lightweight Design (289.6mm × 22mm):

With a 289.6mm diameter and 22mm thickness, this front brake disc features a compact, weight-optimized design suited to commercial vehicle applications where unsprung mass and fuel efficiency are important considerations. The reduced rotational mass contributes to improved fuel economy — a significant cost factor for commercial fleets operating high annual mileages — while the precisely engineered disc thickness provides adequate thermal mass and heat dissipation capacity for the vehicle's front-axle braking requirements. Despite its compact dimensions, the disc maintains full structural integrity and meets all ECE R90 performance and safety standards.

• Coated Anti-Corrosion Protection for Commercial Environments:

The coated surface finish on this commercial vehicle brake disc provides a durable, uniform layer of corrosion protection that shields the disc from road salt, moisture, de-icing chemicals, and environmental oxidation — hazards commonly encountered in commercial fleet operations across diverse global climates. Unlike basic oiled treatments that may wear off quickly during heavy use, the coated finish adheres tightly to the disc surface and maintains its protective properties through extended service intervals, preventing rust-related surface pitting, irregular wear, and premature disc replacement. The coating also preserves a clean, professional appearance on vehicles where the brake disc is visible through wheel openings.

• High-Carbon Gray Iron Thermal Performance (G3000 / GG15HC, DIN & SAE):

Cast from premium high-carbon gray iron conforming to G3000 and GG15HC material grades and formulated to both DIN and SAE standards, this commercial vehicle brake disc delivers reliable thermal performance and structural strength under the demanding conditions of front-axle commercial braking. The elevated carbon content creates a dense, lamellar graphite microstructure that provides excellent thermal conductivity, allowing heat to dissipate quickly and evenly across the disc surface, and inherent vibration damping that contributes to the quiet operation of the disc. The material also resists thermal cracking and warping even when exposed to the rapid temperature fluctuations of frequent stop-and-go commercial driving.

• ECE R90 Certified & Precision-Manufactured Quality:

Fully certified to ECE R90 standards and produced in an IATF16949-certified manufacturing facility with ISO14001 environmental and ISO45001 occupational health management system compliance, this commercial vehicle front brake disc meets stringent international safety and performance requirements. Each disc undergoes precision turning and grinding to achieve strict dimensional tolerances, a perfectly flat friction surface, and exact hub-centric fitment, followed by dynamic balancing and multi-stage quality inspection before packaging in boxes, cartons, pallets, or bulk configurations for global distribution. Private label and customized branding options are available to meet specific fleet and distributor requirements.

Brake Pads Features:

•High performance 

•Long-life service 

•Anti-fade 

•Low noise, low dust 

•Environmental friendly

• Commercial Vehicle-Grade Friction Compound:

Formulated specifically for commercial vehicle front-axle applications, these pads deliver a consistent, high coefficient of friction engineered to handle the increased vehicle weights and frequent braking cycles typical of commercial fleet operations. The friction material is designed for stable performance across a broad temperature range, ensuring reliable stopping power whether the vehicle is making low-speed urban deliveries or highway-speed emergency stops, and providing commercial drivers with predictable, confidence-inspiring brake feel in all operating conditions.

• Extended Wear Life for Reduced Fleet Maintenance:

The wear-resistant friction formulation and reinforced steel backing plate are engineered to withstand the high-frequency braking demands of commercial vehicle operations, delivering significantly extended service life compared to standard replacement pads. This reduces maintenance frequency, lowers total cost of ownership, and minimizes vehicle downtime — critical factors for fleet operators and commercial users managing high-mileage vehicles on tight schedules.

• Quiet Operation & Low Noise Emission:

Precision-ground friction surfaces, chamfered edge design, and under-layer noise dampening work together to minimize brake squeal, chatter, and vibration, complementing the quiet brake disc design and delivering a refined, low-noise braking experience. For commercial drivers spending extended hours in the vehicle, this reduction in brake noise contributes to a less fatiguing cabin environment and improved overall driving comfort.

• Low-Dust Formulation for Cleaner Commercial Vehicles:

The advanced low-dust friction formulation minimizes unsightly brake dust accumulation on wheels, keeping commercial vehicles looking cleaner and more professional between washes — an important consideration for fleet operators concerned with brand image and vehicle presentation. The coated disc surface also helps prevent rust staining that can detract from vehicle appearance.

• Environmentally Responsible Manufacturing:

Produced under ISO14001-certified environmental management systems, these pads are manufactured with resource-efficient processes and formulations designed to minimize environmental impact. The production workflow prioritizes responsible material sourcing, waste reduction, and emissions control, ensuring that commercial-grade braking performance is achieved without compromising environmental sustainability.
