Installing Sensors on Non-ABS-Prepped Axles
Sensor locations vary due to suspension type. WABCO recommends placing the sensor on the axle that
will provide the most braking performance. Contact your suspension manufacturer for further information.
1.
Apply a mineral oil-based grease that contains molydisulfide to the sensor spring clip, the body of the
sensor and the bore of the sensor block. The grease must be anti-corrosive and contain adhesive
properties that will continuously endure temperatures from −40° to 300°F (−40° to 150°C).
2. Push the spring clip into the sensor holder from the inboard side, until the spring clip tabs are against
the sensor holder. Push the sensor into the spring clip as far as possible.
Use WABCO spring clips to ensure a correct fit.

4. Route the sensor cable toward the brake chamber, over the brake spider or through the pre-stamped
hole dedicated to ABS sensors. Route to the back side of the axle. Secure the cable to the axle
between the brake spider and the suspension brackets. Continue to route the sensor cable behind the
spring seats. Secure the cable to the axle one inch from the molded sensor plug.
Do not overtighten tie wraps on a cable. Overtightening can damage the cable. Do not tie wrap the
molded sensor plug. The sensor extension cable must follow the brake hose to the ECU/valve
assembly to allow for axle jounce and rebound.
