Here's a general outline. Specifics may vary slightly depending on your Maxima's trim level. Always consult a repair manual specific to your 1993 Nissan Maxima for detailed instructions and diagrams. This is a simplified overview and omits some crucial safety steps.
Tools You'll Need:
* Jack and jack stands
* Wheel chocks
* Lug wrench
* Socket wrench with appropriate sockets (likely 14mm, 17mm, and possibly others)
* Pliers or C-clamp (for compressing caliper piston)
* Brake cleaner
* Wire brush (optional, for cleaning caliper)
* New front brake pads (ensure you get the correct ones for your Maxima)
* Gloves
* Safety glasses
Procedure:
1. Safety First: Park on a level surface, engage the parking brake firmly, and chock the rear wheels. Raise the front of the car using the jack and securely support it with jack stands.
2. Remove the Wheel: Loosen the lug nuts on the wheel you'll be working on before jacking the car up. Then remove the wheel and set it aside.
3. Expose the Caliper: You should now see the brake caliper clamped around the rotor.
4. Compress the Caliper Piston: This is crucial. The new brake pads are thicker than the old ones, so you need to push the piston back into the caliper. Use a C-clamp or specialized piston compression tool. Do this slowly and steadily to avoid damaging the piston or seals. You may need to turn the piston as you push it in.
5. Remove the Brake Pads: There are usually retaining pins or clips holding the brake pads in place. Remove these and carefully slide the old brake pads out. You might need to use a small pry tool to help remove them if they're stuck.
6. Clean the Caliper: Use a wire brush to remove any rust or debris from the caliper and slider pins. Clean the caliper bracket and the caliper itself with brake cleaner.
7. Install the New Brake Pads: Carefully insert the new brake pads into their respective slots. Make sure they slide in easily and are properly seated.
8. Reassemble: Replace the retaining pins or clips. Reinstall the wheel, tightening the lug nuts in a star pattern.
9. Lower the Vehicle: Carefully lower the vehicle using the jack.
10. Check for Proper Installation: Pump the brake pedal several times to engage the brakes. Check for any leaks around the caliper.
11. Test Drive: Take a short test drive to check for proper braking performance. If you notice anything unusual, such as vibration or a pulling sensation, take your vehicle to a professional immediately.
Important Considerations:
* Rotor Inspection: While you're at it, inspect the brake rotors for wear and tear. If they're excessively worn or scored, they may need to be replaced or resurfaced.
* Lubrication: Lightly lubricate the caliper slider pins with a high-temperature brake lubricant.
* Bleeding Brakes (Potentially Necessary): In some cases, you might need to bleed the brakes after replacing the pads. This is to remove any air that may have entered the brake lines during the process. This requires special tools and knowledge.
* Brake Fluid: Check your brake fluid level before and after the job.
Disclaimer: This is a simplified guide. Incorrectly performing brake work can be extremely dangerous. Refer to a repair manual specific to your vehicle for detailed instructions and safety precautions. If you're unsure about any step, consult a qualified mechanic.
