CALIPERS
You are not required to replace or rebuild calipers in axle
sets. However, when replacing or rebuilding a caliper due to the
conditions that follow, you may suggest servicing, rebuilding, or
replacement of the other caliper (on the same axle) for improved
performance and preventive maintenance (for example, the part is close
to the end of its useful life, replacing the caliper may extend pad
life, or contribute to more balanced braking).
CAUTION: When installing loaded calipers, it is required that
friction material be matched in axle sets for consistent
braking characteristics.
