🔧 Pathfinder - Front Brake Pads & Rotor Replacement

You’ll remove the front calipers, replace the brake pads and rotors, then reinstall everything with the correct tightening. This restores stopping power and fixes pulsing/shaking caused by worn pads or warped rotors.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• 🛑 Support your Pathfinder on jack stands—never rely on a floor jack alone.
• 🛑 Keep the ignition OFF and keys away so nobody can move the shifter while it’s lifted.
• 🛑 Do not let the brake caliper hang by the hose—support it with a hook/strap.
• 🛑 Brake dust is unhealthy—use brake cleaner, not compressed air.
• 🛑 Front brakes do not require EPB service mode, but keep your hands clear of pinch points.

📋 Before You Begin

• Park on level ground, put the shifter in Park, and set the parking brake.
• Place wheel chocks behind the rear tires.
• Crack the front lug nuts loose 1/2 turn using a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir. You may need to remove a little fluid later if it looks near “MAX.”
• A brake caliper piston compressor is a tool that slowly pushes the caliper piston back in so the new, thicker pads fit.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the front wheels

• Use a floor jack (rated 3-ton minimum) to lift the front of your Pathfinder and set it securely on jack stands (rated 3-ton minimum).
• Remove the lug nuts with a 21mm socket and ratchet, then remove both front wheels.

Step 2: Remove the front brake caliper

• Turn the steering wheel to give yourself room (left for the right side, right for the left side).
• Remove the caliper slide bolts using a 14mm socket and ratchet.
• Lift the caliper off the pads/rotor and hang it from the strut spring with a bungee cord.

Step 3: Remove the old pads and hardware

• Pull the pads out of the bracket by hand (use a flathead screwdriver gently if they’re stuck).
• Remove the pad clips/hardware from the bracket (use a flathead screwdriver).

Step 4: Remove the caliper bracket

• Remove the caliper bracket bolts using a 22mm socket and breaker bar.
• Set the bracket aside.
• On reassembly: Torque to 137 Nm (101 ft-lbs).

Step 5: Remove the old rotor

• Pull the rotor straight off.
• If it’s rust-stuck, tap around the hat (center “drum” area) with a rubber mallet until it breaks free.

Step 6: Clean and prep the hub and new rotor

• Clean the hub face with a wire brush so the new rotor sits flat.
• Spray the new rotors with brake cleaner to remove protective oil and wipe clean.
• Apply a paper-thin smear of anti-seize compound to the hub face (avoid the wheel studs). Less is more.

Step 7: Reinstall the rotor and bracket

• Slide the new rotor onto the hub.
• Reinstall the caliper bracket and start bolts by hand.
• Tighten using a 22mm socket and torque wrench: Torque to 137 Nm (101 ft-lbs).

Step 8: Install new pad hardware and pads

• Install the new pad clips/hardware into the bracket.
• Apply a light film of high-temperature silicone brake grease where the pads slide on the hardware (not on the pad friction material).
• Install the new pads into the bracket.

Step 9: Compress the caliper piston

• Place the old inner pad against the piston face (helps spread force evenly).
• Use the brake caliper piston compressor (specialty) to slowly push the piston fully back into the caliper.
• Watch the brake fluid reservoir as you compress. If it’s about to overflow, remove a little fluid (keep fluid off paint).

Step 10: Reinstall the caliper

• Slide the caliper back over the new pads/rotor.
• Install the slide bolts using a 14mm socket.
• Tighten using a torque wrench: Torque to 27 Nm (20 ft-lbs).

Step 11: Reinstall wheels

• Reinstall both wheels and hand-thread lug nuts.
• Lower the Pathfinder until the tires just touch the ground, then torque lug nuts in a star pattern using a 21mm socket and torque wrench.
• Torque to 133 Nm (98 ft-lbs).

✅ After Repair

• With the engine OFF, press the brake pedal 10-15 times until it feels firm. This seats the pistons against the new pads.
• Check brake fluid level and top off with DOT 3 brake fluid if needed.
• Start the engine and confirm the pedal feels normal (no sinking).
• Test-drive at low speed first and confirm no pulling, grinding, or warning lights.
• Pad bedding (recommended): do 5-6 medium stops from ~40 to ~10 mph, letting brakes cool a minute between. Avoid hard stops at first.
