Essentials:
* Jack and jack stands: Crucial for safely lifting the vehicle. Never work under a vehicle supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket wrench set (metric): You'll need various sizes, likely including 13mm, 15mm, and possibly others depending on the specific caliper design. A ratchet handle, extensions, and a universal joint will greatly aid access.
* C-clamp or caliper compression tool: To compress the brake caliper piston. A C-clamp works, but a dedicated caliper compressor is safer and easier.
* Wrench for caliper bolts: The size will depend on your Explorer, check your vehicle's service manual.
* Screwdriver (likely Phillips): For removing caliper guide pins (potentially).
* Brake cleaner: To clean the brake caliper and rotor surfaces.
* Penetrating oil (like PB Blaster): To help loosen any rusted or stuck bolts.
* Gloves: To protect your hands from grease and dirt.
* Safety glasses: To protect your eyes from flying debris.
Highly Recommended:
* Torque wrench: To ensure the bolts are tightened to the manufacturer's specifications. Improper torque can lead to brake failure. Check your owner's manual or a repair manual for specifications.
* Wire brush: To clean rust and debris from caliper mounting surfaces.
* Rotor turning tool: While not strictly necessary, this tool helps ensure the rotor is properly centered on the wheel hub during installation. A hammer and soft mallet can work as a substitute, but it's less precise.
* Shop manual or repair manual specific to your 1994 Ford Explorer: This will provide detailed instructions, torque specifications, and diagrams specific to your vehicle.
Potentially Needed:
* Hammer: Might be needed to tap things loose if they're particularly stubborn.
* Pry bar: Could be helpful for separating brake parts if they're stuck together.
Important Considerations:
* Brake fluid: You may need to bleed the brakes after the job is complete, especially if you've removed the calipers completely. If so, you'll need a brake bleeder kit. Some brake fluid may spill during compression. Have rags ready.
* Anti-seize compound: Apply a thin layer to caliper bolts to prevent them from seizing in the future.
Before starting the job, consult a repair manual for your specific vehicle year and model. This will give you the most accurate information and torque specifications. If you're not comfortable working on brakes, it's best to take it to a professional mechanic. Brake failure is extremely dangerous.
