Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: For added safety.
* Socket wrench set: Metric sockets are crucial. You'll need various sizes, likely including 13mm, 14mm, and possibly others.
* Wrench set: For various fasteners.
* C-clamp or brake caliper compressor tool: To compress the caliper piston.
* Pliers: To remove brake caliper retaining pins (if present).
* Screwdrivers: Phillips and flathead, likely needed.
* Brake cleaner: To clean brake parts.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or seized bolts.
* New brake pads: Ensure you get the correct pads for your Ranger model.
* New rotors (likely): Rotors often need replacing with new pads, especially if they're grooved or worn below the minimum thickness. Check the rotor thickness before starting.
* Gloves: Protect your hands.
* Safety glasses: Protect your eyes.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the truck using the jack and securely place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Locate the caliper bolts: These are usually on the back of the caliper.
* Spray penetrating oil: Liberally apply penetrating oil to the bolts to help loosen them.
* Remove the caliper bolts: Use the appropriate socket wrench to carefully remove the bolts.
* Support the caliper: Use a bungee cord or wire to hang the caliper from the suspension, preventing it from dangling by the brake line. Do not let the brake line hang unsupported.
4. Compress the Caliper Piston: Use a C-clamp or a brake caliper compressor tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. You may need to turn the piston as you compress it.
5. Remove the Old Brake Pads: The old pads should slide out from between the caliper and the rotor.
6. Inspect the Rotor: Check the rotor for wear and scoring. If it's grooved, worn below the minimum thickness (check your owner's manual or the rotor itself for markings), or damaged, replace it.
7. Install New Pads: Install the new brake pads into the caliper.
8. Install the Caliper: Mount the caliper back onto the caliper bracket and tighten the caliper bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Don't overtighten!
10. Repeat for the Other Side: Follow the same steps for the other front wheel.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Pump the Brakes: Get back in the truck and firmly pump the brake pedal several times to build up brake pressure. Check for leaks.
13. Test Drive: Take a short test drive to ensure the brakes are working correctly.
Important Notes:
* Brake fluid: If you're replacing the brake lines or doing a more extensive brake job, you may need to bleed the brakes to remove air bubbles from the system. This is more advanced and requires specialized tools.
* Torque Specifications: Always refer to your owner's manual or a repair manual for the correct torque specifications for all bolts. Over-tightening can damage components.
* Professional Help: If you are uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Brake repairs are crucial for safety.
This guide provides a general overview. Variations may exist depending on your specific vehicle. Always prioritize safety and consult your owner's manual or a repair manual for detailed instructions specific to your 1992 Ford Ranger.
