How do i remove the brake caliper on a 1994 f350 4x4 there are no bolts attaching it

If this is a Pin Slider, here is 1996 steps:

Section 06-03: Brakes, Front Disc 1996 F-150, F-250, F-350 4x2, 4x4, Bronco and F-Super Duty Vehicles Workshop Manual
REMOVAL AND INSTALLATION Caliper
Heavy-Duty Rail Slider, F-Super Duty
Replace brake shoe and lining (2001) as follows when the lining is worn to a minimum thickness of 0.794mm (1/32 inch) above the front disc brake rotor shield. CAUTION: Always replace all brake shoes and linings on an axle. Never replace only one wheel (1007).
Removal

1. To avoid fluid overflow when the caliper pistons are pressed into the caliper cylinder bores, siphon or dip part of the brake fluid out of the brake master cylinder reservoir (2K478). Discard the removed fluid.
   

1. Raise the vehicle and install safety stands. Remove the front wheel and tire assembly.
   

1. Place an appropriate size C-clamp on the disc brake caliper with end of clamp against caliper and end of screw against outer shoe. Tighten the clamp to bottom the caliper pistons in the cylinder bores. Remove the clamp. Do not use a screwdriver or similar tool to pry caliper pistons (2196) away from the front disc brake rotor (1125).
   
   
   
   
   

1. Clean excess dirt from area around pin tabs.
   

1. Tap upper caliper pin toward inboard side until pin tabs touch the front wheel spindle.
   

1. Using Hydraulic Caliper Pin Remover D89T-2196-A or equivalent and a light hammer, drive the pin from the disc brake caliper as follows:
   
   1. Position the notched end of the tool against the caliper pin (retention tab half), at a 45-degree angle from the pin retention tabs.
      
      
      
      
   1. Tap the tool with the hammer to compress the retention tabs.
      
      
      
      
   1. As the retention tabs are compressed, move the tool to gain a straight approach to the caliper pin, and continue tapping to drive the caliper pin through the caliper/spindle groove.

1. Repeat removal procedure for lower caliper pin.
   

1. CAUTION: Do not let the disc brake caliper hang by the front brake hose (2078). The front brake hose could become stretched or twisted which can cause the front brake hose to leak and rupture, resulting in failure.
   Remove the disc brake caliper from the front disc brake rotor. If the disc brake caliper is to be removed for service, remove the front brake hose from the disc brake caliper. Plug the end of the front brake hose to prevent fluid loss and entry of air into the system. If the disc brake caliper is not to be removed, wire it up to the frame of the vehicle to avoid damage to the front brake hose.
   

1. NOTE: There is a raised section at one end of each shoe so installation can be made in one direction only.
   
   Install new inner and outer lining.
   

1. Lubricate the knuckle upper and lower inner pad grooves and caliper grooves with Disc Brake Caliper Slide Grease, Silicone Dielectric Compound D7AZ-19A331-A or equivalent meeting Ford specification ESE-M1C171-A. Install the disc brake caliper on a front wheel spindle, making sure thhow do i remove the brake caliper on a 1994 f350 - stj~us~en~file=ani_caut.gif~gen~ref.gifbr />

1. CAUTION: Do not allow the tabs of the caliper pin to be tapped too far into the spindle groove. If this happens it will be necessary to tap the other end of the caliper pin until the tabs snap into place. The tabs on each end of the caliper pin must be free to catch on the spindle flanks.
   Position caliper pin with the pin retention tabs oriented adjacent to the spindle groove.
   

1. Tap the caliper pin on the outboard end with a hammer. Continue tapping the caliper pin inward until the retention tabs on the sides of the caliper pin contact the spindle face. Repeat procedure for the lower caliper pin.
   
   
   

If you look in between the caliper and the caliper bracket you will see a metal sleeve with a rubber bushing that sits in the slots on the top and bottom of the caliper. Use a punch and hammer to pound those sleeves out from in between the caliper and bracket. You will then be able to remove the caliper.
