Ranger 2WD V6-245 4.0L VIN X SFI (1997)
Disc Brake Caliper
4. Lubricate the caliper bores, new piston seals and the caliper pistons with clean Ford High Performance DOT 3 Brake Fluid C6AZ-19542-AA or
equivalent DOT 3 fluid meeting Ford specification ESA-M6C25-A.
CAUTION: Do not use anything but clean brake fluid to lubricate the caliper pistons, seals and caliper bores. Use of any other lubricant may
cause premature failure of brake components.
5. Install the new piston seals into the caliper bore seal grooves. Make sure the seals are not twisted and are fully seated.
6. Install the caliper pistons into the caliper bores past the piston seals. Use a rocking, twisting motion and use care not to distort the piston seals.
7. After the caliper pistons are past the piston seals press the caliper pistons about 2/3 into the caliper bores.
8. Install the new dust boots on the caliper pistons.
CAUTION: Effective operation of the disc brake caliper is directly affected by the condition of the caliper piston dust boots. Use care not to
dislodge or damage them.
9. Using Piston Dust Seal Replacer T92P-2588-AH and Driver Handle T30T-4000-W seat the dust boots into the caliper bores. Make sure the dust
boots are fully seated into the caliper piston grooves and caliper bore grooves. After installation, the dust boots should not extend beyond the face
of the caliper piston.
10. After installing the dust boots, press the caliper pistons to the bottom of the caliper bores.
11. Install the caliper slide pin dust boots into the disc brake caliper anchor plate. Make sure the boots are fully seated in the grooves.
CAUTION:
^
The caliper slide pins are covered by a flexible boot and are intended to be lubed for life. At time of publication, there was no approved
material or procedure for re-lubing the caliper slide pins. For routine service such as brake pad replacement, the slide pins, grease and boots
should be reused as are, if not damaged. If damaged, new pins (with new boots and grease included) must be installed.
^
Do not use petroleum or mineral based service greases (such as Ford Disc Brake Caliper Slide Grease D7AZ- 19590-A or equivalent meeting
Ford specification ESA-M 1C172-A) for this application. Such greases will cause rapid deterioration of the slide pin boots. Service life of the
disc brakes could be reduced as a result.
12. Install the caliper slide pins into the caliper slide pin boots. Make sure the caliper slide pin boots are seated in the grooves in the caliper slide pins.
13. Expel the air from the caliper slide pin boots and make sure the caliper slide pins are fully coated with lubricant.
14. Install the disc brake caliper.
