This "Cylinder Pad Left 1.16mm 5 Layers" is a precision-engineered sealing component designed for specific automotive braking systems. Its primary function is to create a reliable seal between the brake cylinder and the brake pad, ensuring optimal hydraulic pressure transfer and consistent braking performance. The designation "Left" indicates this pad is for the left-side wheel assembly, crucial for correct installation and vehicle balance.

The precise 1.16mm thickness is a critical specification, engineered to meet the exact clearance and tolerances of particular brake caliper models. This ensures proper fitment, prevents rattling, and allows for efficient piston retraction, which minimizes drag and promotes even pad wear. Using a component with an incorrect thickness can lead to reduced braking efficiency, premature wear, or caliper damage.

The construction of "5 Layers" signifies a multi-material composite design. Typically, this involves layers of specialized materials such as steel, adhesive, rubber, and sometimes insulating or anti-vibration compounds. This layered architecture provides superior durability, effective damping of vibrations and noise, and enhanced resistance to heat and brake fluid. It translates to a quieter, more responsive braking feel and extended service life for both the pad and the caliper.

When sourcing a replacement cylinder pad, matching these exact specifications—side, thickness, and layered construction—is paramount. This component is essential for maintaining the integrity of the braking system’s hydraulic operation. Always verify compatibility with your vehicle’s make, model, and year to ensure safety and performance that meets original equipment standards.
