Description
Restore smooth caliper operation and ensure precise electronic brake wear monitoring with the genuine-spec Knorr-Bremse Air Disc Brake Caliper Repair Kit & Sensor Set (OE K000684). Engineered specifically for heavy-duty commercial air disc brake systems, this comprehensive wholesale kit combines high-grade EPDM rubber guide boots, internal seals, specialized high-temperature grease, and a matching electronic brake pad wear sensor. Worn boots allow moisture and road grit to seize the caliper, while failing sensors compromise electronic dashboard diagnostics. This professional-grade maintenance kit solves both challenges directly. It utilizes premium elastomers and precision electronics to maintain airtight pneumatic integrity, ensure effortless caliper sliding, and provide accurate real-time wear alerts for your commercial transport fleet.
Technical Parameters
| Category | Specifications & Technical Details |
| Exact OE Part Number K000684 Specification | We manufacture this kit strictly to the Knorr-Bremse OEM K000684 technical standard. As a result, the overhaul seal components match the on-board electronic sensor electrical interface and physical dimensions 100%. |
| High-Sensitivity Electronic Brake Wear Sensor | We equip the kit with an OEM-grade high-temperature electronic sensing harness and probe. Consequently, it precisely monitors remaining brake pad thickness. Moreover, it sends a clear, reliable warning signal to the dashboard when wear reaches the limit. |
| Specialized High/Low-Temperature EPDM Rubber Boots | We select premium EPDM rubber material. Therefore, it maintains outstanding elasticity from -40°C extreme cold to +150°C continuous braking heat. Notably, it never hardens or cracks. |
| Precision Multi-Lip Guide Pin Dust Sealing | We equip the kit with tightly fitted multi-lip guide pin dust boots. As a result, they completely block de-icing salt, mud, high-pressure wash water, and road moisture from entering the sliding cavity. Meanwhile, they prevent caliper sticking. |
| Long-Lasting High-Temperature Synthetic Caliper Grease | We include professional high-temperature, anti-seize synthetic grease with the kit. Consequently, it greatly reduces guide pin sliding friction resistance. In addition, it ensures free caliper floating and balanced braking. |
Applicable Car Brands & Models
The K000684 wholesale package typically includes heavy-duty EPDM rubber guide pin boots, precision internal sealing O-rings, dust covers, a packet of specialized high-temperature synthetic caliper grease, and a matching electronic brake pad wear sensor with factory plug connectors.
Replacing both components together ensures optimal fleet maintenance efficiency. While the repair kit restores mechanical sliding freedom and pneumatic sealing, the new sensor guarantees accurate electronic wear monitoring, preventing unexpected dashboard warnings and premature pad rotor damage.
Fleet maintenance professionals should inspect rubber boots and sensor wiring during every routine brake pad change (typically every 50,000 to 100,000 kilometers) and replace them immediately if boots show tearing or sensors trigger intermittent dashboard faults.
Yes, absolutely. We offer flexible bulk wholesale packaging options for commercial fleet operators, truck repair workshops, and heavy-duty parts distributors worldwide, complete with secure moisture-resistant industrial boxing for safe global transit.
