Tools You'll Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Socket wrench set: Including metric sizes (likely 13mm, 14mm, and possibly others).
* C-clamp or brake caliper compression tool: To compress the caliper piston. A C-clamp works, but a dedicated tool is easier and safer.
* Pliers: May be needed to remove caliper retaining pins.
* Wire brush: To clean caliper surfaces.
* Brake cleaner: To clean brake parts.
* New brake pads: Make sure you get the correct pads for your Ranger's model.
* Penetrating lubricant (PB Blaster or similar): Helpful for loosening stuck caliper bolts.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Jack up the front of the vehicle and securely support it on jack stands. Remove the wheel.
2. Inspect the Brake System: Before you start, take a moment to inspect the rotors, brake lines, and caliper for any obvious damage. Worn or damaged components should be replaced.
3. Remove the Caliper:
* Locate the caliper retaining pin(s). These are usually located at the top and bottom of the caliper. Spray penetrating lubricant if needed.
* Using pliers or a socket, carefully remove the retaining pins.
* Depending on your Ranger, there might be a single bolt or multiple bolts securing the caliper. Use a socket wrench to remove these bolts.
* Carefully remove the caliper from the rotor. It may be attached with a metal bracket. Support the caliper with a wire or rope to prevent it from hanging by the brake line.
4. Compress the Caliper Piston: This is crucial. The new brake pads are thicker than the old ones, so you need to create space.
* Use the C-clamp or caliper compression tool to slowly and evenly compress the caliper piston. It will likely require some force. Be careful not to damage the piston or brake lines. Turning the piston can sometimes help.
5. Remove the Old Brake Pads: The old brake pads should now slide out of their slots. If they are stuck, a small pry tool can help.
6. Clean the Caliper and Rotor: Use a wire brush to clean any rust or debris from the caliper mounting surfaces and the rotor's braking surface. Clean everything with brake cleaner.
7. Install the New Brake Pads: Carefully insert the new brake pads into their slots. Make sure they are seated correctly.
8. Reinstall the Caliper: Carefully slide the caliper back over the rotor and the new brake pads. Reinstall the caliper retaining pin(s) and bolts. Tighten the bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Tighten the lug nuts in a star pattern.
10. Lower the Vehicle: Carefully lower the vehicle to the ground.
11. Check for Proper Operation: Before driving, pump the brake pedal several times to ensure that the pads are making contact with the rotors. Test the brakes gently at low speed in a safe area to verify their functionality.
12. Repeat for the Other Side: Repeat the process for the other front wheel.
Important Considerations:
* Torque Specifications: Always consult your owner's manual or a repair manual for the correct torque specifications for the caliper bolts and lug nuts. Over-tightening can damage components.
* Rotor Condition: Inspect the brake rotors for wear. If they are scored, warped, or too thin, they need to be replaced or resurfaced.
* Brake Fluid: While not directly involved in pad replacement, you should have your brake fluid checked periodically, and consider a flush and refill if needed.
This guide provides a general overview. If you're uncomfortable performing this repair, it's best to take your Ranger to a qualified mechanic. Improper brake repair can be extremely dangerous.
