Prowler V6-3.5L VIN G (1999)
Removing Piston Seal From Caliper
8. Using a soft tool, such as a plastic trim stick, work piston seal out of its groove in caliper piston bore. Discard old seal. Do not use a screw driver
or other metal tool for this operation, because of the possibility of scratching piston bore or burring edges of seal groove.
9. Clean all parts using alcohol or a suitable solvent and wipe dry using only a lint free cloth. No lint residue can remain in caliper bore. Clean out all
drilled passages and bores. Whenever a caliper has been disassembled, a new boot and seal must be installed at assembly.
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.
