Cleaning, Inspecting & Honing Caliper
Fig 14 Honing Piston Bore
Clean all parts using alcohol or a suitable solvent and blow dry, using compressed air. Blow out all drilled passages and bores.
NOTE: Whenever a caliper has been disassembled, a new boot and seal must be installed at reassembly.
Inspect the piston bore for scoring or pitting.
-
Install a new piston if it is pitted, scored or the plating is severely worn.
-
Bores that show light scratches or corrosion, can usually be cleared with crocus cloth.
-
Bores that have deep scratches or scoring should be honed, using Tool C-4095, or equivalent, providing the diameter of the bore is not
increased more than 0.002 inch (0.050mm).
-
If the bore does not clean up within this specification, a new caliper housing should be installed.
