Honing Brake Caliper Piston Bore
10. Inspect the piston bore for scoring or pitting. Bores that show light scratches or corrosion can usually be cleared of the light scratches or corrosion
using crocus cloth. Bores that have deep scratches or scoring should be honed. Use Caliper Hone, Special Tool C-4095, or equivalent providing
the diameter of the bore is not increased more than 0.0254 mm (0.001 inch).
11. If the bore does not clean up within this specification, a new caliper housing should be installed. Install a new piston if the old one is pitted or
scored.
NOTE: When using Caliper Honing Tool, Special Tool C-4095, coat the stones and bore with brake fluid. After honing the bore, carefully clean
the seal and boot grooves with a stiff non-metallic rotary brush.
NOTE:Use extreme care in cleaning the caliper after honing. Remove all dirt and grit by flushing the caliper with brake fluid; wipe dry with a
clean, lint free cloth and then clean a second time.
CAUTION: When inspecting caliper piston, do not use anything but solvents to clean piston surface. If surface of piston cannot be cleaned using
only solvents, piston must be replaced.
12. Inspect caliper piston for pitting, scratches, or any physical damage. Replace piston if there is evidence of scratches, pitting or physical damage.
CALIPER ASSEMBLY
CAUTION: Excessive vise pressure will cause bore distortion and binding of piston.
1. Clamp caliper in a vise (with protective caps installed on jaws of vise).
