Semi-metallic Brake Pad for ACURA Rear ECE R90

Brake Pad Features

• You press the pedal. The vehicle slows. Simple, right? Not quite. Every stop involves hundreds of microscopic interactions between pad and disc—friction events that generate heat, create dust, and gradually wear both components. The rear brakes manage a smaller share of the stopping force, but they face unique challenges: less frequent use can lead to glazing, and road spray exposes them to more corrosion. This pad was engineered for those challenges. The semi-metallic formulation compresses iron powder, copper fibers, and other metallic substrates with high-temperature resin, creating a friction compound that delivers consistent force across the full operating range.

• The dimensions—88.77mm in length, 47.6mm in width, 15.2mm in thickness—match the Acura rear brake specifications for models including the TLX-L, RDX, MDX, and ZDX. The pad fits the caliper without modification. The backing plate aligns with the piston. Installation is straightforward, requiring no creative adaptation. For workshops that service Acura vehicles, this means the job stays within the time estimate. For drivers, it means the brakes work as the vehicle's designers intended.

• The friction coefficient of this pad is calibrated to the 0.38-0.42 range. That range is not chosen by accident; it is the sweet spot where rear brake response is linear and predictable, complementing the front brakes without overwhelming the rear axle. The dynamometer testing that ECE R90 certification requires has validated this friction stability, confirming that the pad delivers consistent stopping power across a range of speeds, temperatures, and pressures. For Acura drivers who value predictable braking, this stability is essential.

• The semi-metallic formulation offers a balanced performance profile. The metallic fibers—iron powder and copper—provide the structural integrity that maintains friction output at high temperatures, preventing the fade that can occur during sustained braking. The resin binder holds the fibers together, ensuring that the pad maintains its shape and composition across thousands of braking cycles. For drivers who encounter mountain descents or high-speed cruising, this balance of durability and thermal stability delivers reliable stopping power.

• The wear resistance of this pad is enhanced by 20% compared to standard pads. The metal fiber-reinforced structure resists the abrasive wear that can occur under high clamping forces, maintaining the pad's thickness and friction surface across its service life. For Acura owners who drive high mileage, this extended service life means fewer replacements and lower maintenance costs over the vehicle's lifetime. The uniform wear pattern also protects the disc from scoring, ensuring that both components last longer.

• The noise reduction coating on this pad buffers the friction vibrations that can cause low-frequency squeals—a common issue in rear brake systems. The coating, applied to the friction surface, disrupts the harmonic patterns that produce brake noise. The result is a pad that brakes quietly, preserving the cabin environment that Acura owners value. For drivers who spend hours on the road, this acoustic refinement reduces fatigue and enhances the enjoyment of the drive.

• The rust-resistant backing plate design is a practical benefit for Acura owners who drive in challenging conditions. The plate resists the corrosion that can cause pads to seize in caliper brackets, turning a simple brake job into a time-consuming repair. The coating resists the effects of rain, snow, and road salts, extending the service life of the pad and simplifying future maintenance. For drivers in coastal regions or winter climates, this corrosion protection is a genuine advantage.

• The compatibility of this pad with Acura's rear brake calipers is complete. The pad follows OEM specifications for hole pattern alignment and caliper fitment, ensuring that the brakes work as the vehicle's designers intended. The pad integrates seamlessly with Acura's braking logic, delivering smooth, predictable stopping power that matches the front brakes. For workshops that value efficiency, this compatibility means fewer installation complications. For drivers, it means the brakes feel right from the first stop.

• The ECE R90 certification confirms that this pad meets the braking performance standards for European aftermarket use, with documented dynamometer testing for friction coefficient, speed sensitivity, and thermal stability. The IATF 16949-certified production facility ensures consistent quality and dimensional accuracy. Whether destined for a TLX in North America, an RDX in Europe, or an MDX in Asia, this pad arrives with the traceability and documentation that professional buyers require—a semi-metallic rear brake component engineered for the balanced, durable, and predictable braking that Acura drivers expect.

Semi-metallic brake pads custom-engineered for Acura rear brake systems, precisely matching rear brake specifications for mainstream models including TLX-L, RDX, MDX, and ZDX. From friction coefficient to mounting dimensions, they adhere to OEM standards, deeply integrated with Acura's power parameters and braking logic. The exclusive choice for dealership aftermarket replacements and owner-initiated OEM upgrades.

Semi-metallic core material delivers balanced performance: Manufactured by compressing high-quality iron powder, copper fibers, and other metallic substrates with resin, the friction coefficient remains stable between 0.38 and 0.42. This perfectly meets the auxiliary braking demands of Acura's rear brakes, ensuring linear and controllable braking force output during operation. It synergizes with front brake pads to achieve smooth braking performance. The metal fiber-reinforced structure enhances high-temperature resistance. During continuous braking on high-speed cruises or long downhill sections, it effectively suppresses thermal fade, ensuring sustained rear braking power.

The product has passed ECE R90 EU safety certification and Acura OEM rigorous testing, strictly meeting Acura rear braking system safety standards. Formulated specifically for rear brake pad load characteristics, wear resistance is enhanced by 20% compared to standard pads. Paired with a special noise-reducing coating, it buffers friction vibrations during braking, minimizing common low-frequency squeals in rear brakes to meet Acura's premium driving experience demands for quiet operation.

Compatible with Acura rear brake caliper OEM specifications, enabling direct installation without additional modifications for quick and efficient fitting. The semi-metallic material offers significant cost-effectiveness, balancing daily usage costs with braking performance for diverse scenarios including city commuting, highway cruising, and family trips. Features a rust-resistant backing plate design to withstand corrosion from rain and snow on rear brake components, extending product lifespan.
