Style C: Where Both the Carrier and Caliper
Have an Indicator Notch
Compare the relative position of two notches cast into the
Carrier and Caliper. See Figure 13. When the two notches
align, it is time to schedule a full wheel-removed inspection
of the pads and rotor. Note: This is only an indication that
the pads and rotor are ready for inspection, and does not
necessarily mean that maintenance is required.
Style D: Where Only the Caliper has an
Indicator Notch
When the notch in the Carrier aligns with the front edge of
the torque plate, it is time to schedule a full wheel-removed
inspection of the pads and rotor. Note: This is only an
indication that the pads and rotor are ready for inspection,
and does not necessarily mean that maintenance is
required.
