The 1990 Ford Ranger's brake system is made of three key components; the brake pads, the caliper, and the rotor. The brake caliper holds the brake pads in place and houses the piston. The brake pads make contact with the rotor to stop the Ranger during braking. To repair the brakes you must correctly identify and replace the component(s). Replace warped or badly scored rotors, worn brake pads and cracked calipers to ensure that the Ford's brakes perform as designed.
Instructions

Park the Ford Ranger on a flat surface. Apply the parking brake and put the transmission in "park."
2Loosen the lug nuts with the tire iron.
3Place the lifting jack beneath the frame of the truck. Lift the vehicle and place jack stands under the frame. Lower the Ranger onto the stands.
4Remove the lug nuts and wheels from the wheel bolts.
5Remove the two caliper bolts on the inside wall of the caliper with a 13 mm wrench. Pull the caliper from the rotor.
6Remove the two bolts on the back side of the caliper bracket with a 16 mm wrench. The bracket is behind the rotor.
7Pull the rotor from the wheel bolts.
8Disconnect the brake line from the caliper using a 10 mm wrench. Place a drip pan beneath the disconnected line to catch any fluid from the hose.
9Place the brake pads into the new caliper. Slide the metal clips of the brake pads over the sides of the caliper.
10Connect the brake line to the new caliper. Screw on the line by hand and tighten with a 10 mm wrench.
11Spray the new rotor with brake cleaner. Wipe the excess cleaner off with a clean towel. Place the new rotor onto the wheel bolts, with the raised "top hat" section facing outward.
12Replace the caliper bracket and screw in the 16 mm bolts. Replace the caliper and screw in the 13 mm caliper bolts.
13Place the wheel onto the wheel bolts and screw on the lug nuts by hand.
14Lift the Ranger to remove the jack stands. Lower the truck to the ground and tighten the lug nuts with the tire iron.
15Press the brake pedal to inject brake fluid into the new caliper. Press and hold the pedal three times.
16Lift the hood of the Ford. Remove the master cylinder cap (located on the driver's side, near the windshield) and add brake fluid as needed.
