Calipers
Caliper Fluid Seal Damage Inspection
  The fluid seal (piston seals) [A] is placed around the pis-
ton to maintain clearance between the pad and the disc. If
the seal is in a poor condition, it could lead the pad to wear
excessively or the brake to drag, which may cause the tem-
perature of the discs or the brake fluid to increase.
• Replace the fluid seal if it exhibits any of the conditions
  listed below.
○Brake fluid leakage around the pad.
○Brakes overheat.
○Considerable difference in inner and outer pad wear.
○Seal and piston are stuck together.
  If the fluid seal is replaced, replace the dust seals [B] as
  well. Also, replace all seals every other time the pads are
  changed.

Caliper Dust Seal Damage Inspection
• Check  that the dust seals [A] are not cracked, worn,
  swollen, or otherwise damaged.
    If they show any damage, replace the dust seals with new
    ones.
