🔧 Pathfinder - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, unbolt the brake caliper and bracket, replace the rotor, then install new pads and reassemble. Doing pads and rotors together prevents noise, vibration, and uneven braking from old, worn rotor surfaces.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• 🛑 Support your Pathfinder with jack stands; never rely on a floor jack alone.
• 🛑 Brakes create dust—wear nitrile gloves and safety glasses; use brake cleaner, not compressed air.
• 🛑 Do not let the caliper hang by the brake hose; support it with a bungee cord.
• 🛑 Brake fluid can damage paint; wipe spills immediately.
• 🛑 Keep fingers clear when compressing the caliper piston.
• 🛑 Battery disconnect is not required for front brakes.

📋 Before You Begin

• Park on level ground, shift to P, and set the parking brake.
• Place wheel chocks behind the rear tires.
• Open the hood and locate the brake fluid reservoir; place a rag around it.
• If the reservoir is very full, use a turkey baster or fluid suction pump (a hand tool that removes fluid) to pull a little fluid out into a drain pan.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and raise the front

• Use a 21mm socket and breaker bar to loosen the front lug nuts about 1 turn (don’t remove yet).
• Use a floor jack to lift the front at the proper jacking point, then set the truck down onto jack stands.
• Remove the lug nuts with a 21mm socket and take the wheels off.

Step 2: Remove the caliper (do not open the brake hose)

• Turn the steering wheel to give yourself more room on the side you’re working on.
• Use a 14mm socket and ratchet to remove the two caliper slide bolts.
• Carefully lift the caliper off the pads/rotor. Support it with a bungee cord.
• Never let the caliper hang by the hose.

Step 3: Remove the old pads and hardware

• Pull the brake pads out of the bracket by hand. If stuck, use a flathead screwdriver gently.
• Remove the stainless pad clips/hardware from the bracket (usually they snap out). Use a flathead screwdriver if needed.

Step 4: Remove the caliper bracket

• Use a 22mm socket, breaker bar, and extension 6" to remove the two caliper bracket bolts.
• Set the bracket aside on a clean surface.
• When reinstalling later: Torque to 137 Nm (101 ft-lbs).

Step 5: Remove the rotor

• Pull the rotor straight off the hub. If it’s stuck from rust, tap the rotor “hat” area with controlled hits (use the handle end of a breaker bar or a firm hand strike) while pulling outward.
• Clean the hub face with a wire brush until it’s smooth (this prevents brake shake).
• Apply a paper-thin layer of anti-seize compound to the hub face (avoid the wheel studs).

Step 6: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray to remove protective oil, then wipe clean with a lint-free rag.
• Slide the new rotor onto the hub.
• To keep it from flopping while you work, thread on 1 lug nut by hand (use a spare) and snug it with a 21mm socket (light snug only).

Step 7: Service the bracket and slide pins

• Install the new pad hardware/clips into the bracket (they should snap in). If needed, use a flathead screwdriver carefully.
• Pull the caliper slide pins out of the bracket by hand.
• Wipe old grease off, then apply fresh brake caliper slide pin grease and reinstall the pins.
• Slide pins must move smoothly by hand.

Step 8: Reinstall the caliper bracket

• Position the bracket over the new rotor and start both bracket bolts by hand.
• Tighten with a 22mm socket and ratchet, then finish with a torque wrench 1/2" drive: Torque to 137 Nm (101 ft-lbs).

Step 9: Install the new pads

• Install the new inner and outer pads into the bracket/hardware by hand.
• If your pad set includes shims, install them exactly as supplied with the pads.

Step 10: Compress the caliper piston

• Place the old inner pad against the caliper piston face.
• Use a C-clamp 6" or disc brake piston compressor (a tool that pushes the piston back) to slowly press the piston fully into the caliper.
• Watch the brake fluid reservoir while compressing; remove fluid with the turkey baster or fluid suction pump if it starts to overflow.

Step 11: Reinstall the caliper

• Remove the temporary lug nut holding the rotor (use a 21mm socket).
• Set the caliper over the new pads.
• Install the slide bolts by hand, then tighten with a 14mm socket and ratchet.
• Finish with a torque wrench: Torque to 34 Nm (25 ft-lbs).

Step 12: Reinstall wheels and torque lug nuts

• Put the wheels back on and hand-thread the lug nuts.
• Lower onto the ground using the floor jack (remove jack stands first).
• Tighten lug nuts in a star pattern using a torque wrench (a tool that tightens to an exact setting): Torque to 133 Nm (98 ft-lbs).

Step 13: Repeat on the other side

• Repeat Steps 2–12 for the other front wheel.
• Always do brakes in pairs on an axle.

✅ After Repair

• With the engine OFF, slowly pump the brake pedal 10–15 times until it feels firm (this seats the pistons against the pads).
• Check the brake fluid level and top off with DOT 3 brake fluid using a funnel if needed.
• Start the engine and confirm the pedal feels normal (it may drop slightly with vacuum assist).
• Test-drive at low speed first. Confirm no pulling, grinding, or warning lights.
• Pad bedding (recommended): make 8–10 medium stops from 60 km/h to 15 km/h, with 30–60 seconds between stops. Avoid hard stops for the first 300–500 km.
• Recheck lug nut torque with a torque wrench after 80–160 km.
