NOTE: Black stains on the piston are caused by the piston seal and will do no harm.
When using Hone C-4095 or equivalent, coat the stones and bore with brake fluid.
After honing the bore, carefully clean the seal and boot grooves with stiff non-metallic rotary brush.
CAUTION: 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, lintless cloth and then clean a second time in the same
manner or until clean cloth shows no signs of discoloration.
