Your Nissan Pathfinder is a capable and reliable vehicle, ready to take on any adventure. But like any machine, it requires regular maintenance to ensure its longevity and safety. One of the most crucial maintenance tasks is changing your brake pads. Brake pads are the vital components that press against your brake rotors, creating friction and slowing down your vehicle. Worn-out brake pads can lead to decreased braking performance, longer stopping distances, and ultimately, a dangerous situation on the road.
Ignoring worn brake pads can have serious consequences. You might experience a grinding or squealing noise when braking, a spongy brake pedal, or even complete brake failure. Regularly inspecting and replacing your brake pads is essential for maintaining your vehicle’s safety and your peace of mind.
This comprehensive guide will walk you through the process of changing brake pads on your Nissan Pathfinder. Whether you’re a seasoned DIY mechanic or a novice looking to learn, we’ll provide clear instructions, helpful tips, and essential safety precautions to ensure a successful brake pad replacement.

Essential Tools and Materials
Before you begin, gather all the necessary tools and materials. Having everything on hand will make the process smoother and more efficient. Here’s a list of what you’ll need:
- New brake pads: Make sure to purchase brake pads specifically designed for your Nissan Pathfinder’s year, make, and model.
- Lug wrench: To remove the lug nuts securing the wheels.
- Jack and jack stands: To safely lift and support the vehicle.
- C-clamp or brake piston compressor tool: To compress the brake caliper piston.
- Socket set and wrenches: Various sizes will be needed to loosen and tighten bolts.
- Brake cleaner: To clean the brake caliper and rotor surfaces.
- Torque wrench: To tighten lug nuts and caliper bolts to the manufacturer’s specifications.
- Gloves and safety glasses: To protect your hands and eyes.
Preparing Your Nissan Pathfinder
Once you have gathered your tools and materials, it’s time to prepare your Nissan Pathfinder for the brake pad replacement.
Parking and Safety
Park your vehicle on a level, stable surface, away from traffic. Engage the parking brake firmly to prevent the vehicle from rolling.
Chocking the Wheels
Place wheel chocks behind the rear wheels to provide an extra layer of safety.
Lifting the Vehicle
Using the jack, carefully lift the front of the vehicle, one side at a time. Ensure the jack is placed on a solid, designated jack point to avoid damaging the vehicle’s frame.
Securing with Jack Stands
Once the vehicle is lifted sufficiently, position jack stands securely under the designated jack points. Never work under a vehicle supported only by a jack. Lower the vehicle slightly onto the jack stands, ensuring they are firmly in place.
Removing the Old Brake Pads
With the vehicle safely lifted and supported, you can now proceed to remove the old brake pads. (See Also: How to Threshold Brake? Master Stopping Power)
Removing the Wheel
Use the lug wrench to loosen the lug nuts on the wheel you’re working on. Once loose, remove the lug nuts completely.
Removing the Caliper
The brake caliper is the component that houses the brake pads. Locate the caliper bolts and use a socket wrench to remove them. The caliper may be attached to the steering knuckle with a bracket or a pin. Remove any necessary brackets or pins to detach the caliper from the knuckle.
Removing the Brake Pads
With the caliper removed, you can now access the brake pads. Gently remove the old brake pads from the caliper bracket.
Inspecting the Brake Rotor and Caliper
Before installing the new brake pads, it’s essential to inspect the brake rotor and caliper for any signs of damage or wear.
Brake Rotor Inspection
Examine the brake rotor for grooves, cracks, or excessive wear. If the rotor is severely worn or damaged, it will need to be replaced.
Caliper Inspection
Inspect the caliper for any signs of corrosion, damage, or sticking. If the caliper is damaged or malfunctioning, it will need to be replaced.
Installing the New Brake Pads
With the old brake pads removed and the brake rotor and caliper inspected, you can now install the new brake pads.
Compressing the Caliper Piston
Before installing the new pads, you’ll need to compress the brake caliper piston. This creates space for the new, thicker brake pads. Use a C-clamp or a brake piston compressor tool to carefully compress the piston back into the caliper.
Installing the New Pads
Align the new brake pads with the caliper bracket and slide them into place. Ensure the pads are seated correctly and are not twisted or misaligned.
Reassembling the Brake System
Once the new brake pads are installed, you can reassemble the brake system. (See Also: What Is the Emergency Brake on a Car? – A Driver’s Guide)
Reinstalling the Caliper
Align the caliper with the brake rotor and slide it back onto the caliper bracket. Replace the caliper bolts and tighten them securely using a torque wrench.
Reinstalling the Wheel
Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle slightly using the jack to ensure the wheel is properly seated.
Tightening the Lug Nuts
Use the lug wrench to tighten the lug nuts in a star pattern, ensuring they are torqued to the manufacturer’s specifications.
Final Checks and Testing
After reassembling the brake system, it’s crucial to perform final checks and tests to ensure everything is working correctly.
Brake Fluid Level
Check the brake fluid level in the master cylinder reservoir. If the level is low, top it off with DOT 3 or DOT 4 brake fluid.
Bleeding the Brakes (Optional)
If you’ve compressed the brake caliper piston, it’s recommended to bleed the brakes to remove any air bubbles from the system. This will ensure optimal brake performance.
Test Drive
Take your Nissan Pathfinder for a test drive in a safe, controlled environment. Gradually apply the brakes at various speeds to ensure they are functioning properly.
Frequently Asked Questions
How often should I change my brake pads?
Brake pad lifespan varies depending on driving habits, road conditions, and other factors. However, a general rule of thumb is to inspect your brake pads every 12,000 miles or 12 months. If they are worn down to 1/4 inch or less, it’s time for a replacement.
What are the signs of worn brake pads?
Common signs of worn brake pads include a squealing or grinding noise when braking, a spongy brake pedal, and reduced braking performance. (See Also: How Much for Brake Pad Replacement? Cost Breakdown Guide)
