Ford Ranger Maintaince And Repair Manual page 972

1. To avoid fluid overflow when the caliper piston is pressed into the caliper cylinder bores, remove or
siphon part of the brake fluid out of the master cylinder reservoir (connected to the front disc brakes).
Discard the removed fluid.
2. Loosen the wheel lug nuts.
3. Raise the vehicle and install jackstands. Remove a front wheel and tire assembly.
4. Place an 1 in. (133mm) C−clamp on the caliper and tighten the clamp slightly to push the caliper
piston in its bore. This will ease caliper removal from the rotor. Remove the clamp.
Do not use a screwdriver or similar tool to pry piston away from the rotor.
5. There are 3 types of caliper pins used: a single tang type, a double tang type and a split−shell type.
The pin removal process is dependent upon how the pin is installed (bolt head direction). Remove the
upper caliper pin first.
On some applications, the pin may be retained by a nut and Torx® head bolt (except the split−shell
type).
6. If the bolt head is on the outside of the caliper, use the following procedure:
1. From the inner side of the caliper, tap the bolt within the caliper pin until the bolt head on the
outer side of the caliper shows a separation between the bolt head and the caliper pin.
2. Using a hacksaw or bolt cutter, remove the bolt head from the bolt.
3. Depress the tab on the bolt head end of the upper caliper pin with a screwdriver, while
tapping on the pin with a hammer. Continue tapping until the tab is depressed by the V−slot.
4. Place one end of a punch,
the caliper pin out of the caliper toward the inside of the vehicle. Do not use a screwdriver or
other edged tool to help drive out the caliper pin as the V−grooves may be damage.
Never reuse caliper pins. Always install new pins whenever a caliper is removed.
7. If the nut end of the bolt is on the outside of the caliper, use the following procedure:
1. Remove the nut from the bolt.
2. Depress the lead tang on the end of the upper caliper pin with a screwdriver while tapping on
the pin with a hammer. Continue tapping until the lead tang is depressed by the V−slot.
3. Place one end of a punch,
the caliper pin out of the caliper toward the inside of the vehicle. Do not use a screwdriver or
other edged tool to help drive out the caliper pin as the V−grooves may be damaged.
8. Repeat the procedure in Step 4 for the lower caliper pin.
