Front Brake Speed Sensor: Replacement

  1. REPLACE FRONT SPEED SENSOR 
    1. Remove the front wheel.
    2. Disconnect the front speed sensor connector.
    3. Remove the front speed sensor with the front axle hub.
    4. Remove the front speed sensor.
      1. Using a pin punch and a hammer, tap out the 2 pins and remove the 2 attachments from SST.

      2. Mount the rear axle hub in a soft jaw vise.
        NOTE: Replace the axle hub assembly if it is dropped or a strong shock is given to it.
      3. Using SST and 2 bolts (Diameter: 12 mm, Pitch: 1.5 mm), remove the speed sensor.

        SST 09520-00031 (09520-00040, 09521-00020), 09950-00020

        NOTE:
        • If the sensor rotor is damaged, replace the axle hub assembly.
        • Do not scratch the contacting surface of axle hub and speed sensor.
    5. Install a new front speed sensor.
      1. Clean the contacting surface of the axle hub and a new speed sensor.
        NOTE: Take care not to stick any foreign objects to the sensor rotor.

      3. Using SST and a press, install the speed sensor to the axle hub.

        SST 09527-10011, 09710-04101, 09950-60020 (09951-00680)

        NOTE:
        • Do not tap the speed sensor with a hammer directly.
        • Check that the speed sensor detection portion is free from foreign objects.
        • Press in the speed sensor straight and slowly.
