Product Description
The Bendix K138983 SB-7 / SN-7 Air Disc Brake Caliper is a heavy-duty replacement braking component designed for compatible commercial vehicles equipped with Bendix air disc brake systems. This right-hand caliper provides the mechanical clamping force needed to press the brake pads against the rotor, helping deliver consistent stopping performance and dependable braking operation.
Manufactured for demanding commercial vehicle service, the K138983 uses a floating-caliper design that allows the braking mechanism to apply pressure across both sides of the rotor. Its robust construction is engineered to withstand frequent braking, vibration, elevated temperatures, and challenging road conditions.
The K138983 is a new replacement assembly, making it suitable for replacing worn, seized, damaged, or malfunctioning air disc brake calipers during brake system maintenance or repairs.

The K138983 corresponds to the right-hand configuration commonly associated with Type B calipers. However, actual installation positions can vary by vehicle and axle design.
Before ordering, verify the original caliper part number, mounting arrangement, brake chamber orientation, and axle configuration. Also confirm whether the replacement requires the complete caliper and carrier assembly or an individual caliper component.
Brake pads, mounting hardware, and included carrier components should be confirmed before installation.
