Floating Pads with metal backing plate: Allows for better alignment of pads to rotor.

Lock-tite on all bolts and screws: Keeps all bolts and screws in place but will release for pad and caliper replacement.

E-Coated Grade 413 aluminum caliper housing: Grade 413 aluminum contains more magnesium and less copper providing a harder and more corrosion resistant compound. E-Coated for added corrosion protection.

Semi-metallic pads: Improved wear over organic pads.

Pressure equalizing port: Port connects the two piston chambers in order to maintain equal pressure and allow brakes to “bleed” properly for improved operation.

Sliding caliper pins with oil impregnated bronze bushing: Allows caliper to float more freely and ensures proper alignment during installation.

Four point mounting bracket: Resists bending in the event the trailer is backed up without reverse solenoid engaged. Mounting surfaces are machined to insure proper alignment of the caliper housing to the rotor. Sliding caliper pins are installed on the mounting bracket at our factory to insure proper pin alignment.

Vented caliper housing: Improves heat dissipation and decreases pad wear.

One piece brass bleeder valves: Resists corrosion and allows for easier bleeding of the brake system.

Rubber booted piston covers: Eliminates the possibility of foreign contamination of the piston housing, ensuring trouble free performance in harsh salt water conditions.

Square O-rings with slant edge: Helps retract pistons away from the rotor when fluid pressure is released. Provides better protection from contamination of brake fluid.
