🔧 Pathfinder - Front Brake Pad Replacement

This repair replaces the worn front brake pads on your Pathfinder. The brake caliper—the clamp that presses the pads against the rotor—must be removed, its pistons compressed, and the new pads installed on both front wheels.

Difficulty Level: Beginner | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and support your Pathfinder with jack stands. Never work beneath a vehicle supported only by a jack.
• ⚠️ Replace the pads on both front wheels so braking remains balanced.
• ⚠️ Brake dust may be harmful. Do not blow it away with compressed air.
• ⚠️ Do not press the brake pedal while either caliper is removed.
• ⚠️ Never allow a caliper to hang from its rubber brake hose.
• ⚠️ Brake cleaner is flammable. Keep it away from sparks and hot surfaces.
• ⚠️ Battery disconnection and electronic parking-brake service mode are not required for the front brakes.

📋 Before You Begin

• 📍 Park your Pathfinder on level pavement, shift to Park, apply the parking brake, and switch off the ignition.
• 📍 Place wheel chocks firmly behind both rear tires.
• 📍 Open the hood and locate the brake-fluid reservoir near the driver-side firewall.
• 📍 Clean around the reservoir cap. Confirm the fluid is not already above the MAX line.
• 📍 If the reservoir is completely full, use the brake-fluid syringe to remove a small amount before compressing the caliper pistons.
• 📍 Do not disconnect the battery or open the hydraulic brake system.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Put on the safety glasses and nitrile mechanic gloves.
• Use the 21mm deep socket and 1/2-inch-drive breaker bar to loosen each front wheel nut about one-quarter turn.
• Do not remove the nuts while the tires are still supporting the vehicle.

Step 2: Raise and Support the Front

• Use the 3-ton floor jack at the front-center suspension crossmember lifting point.
• Position the 3-ton jack stands beneath the reinforced left and right front support points.
• Lower your Pathfinder onto the stands, then gently push the body to confirm it is stable.
• Leave the floor jack lightly touching the lifting point as an additional backup.

Step 3: Remove Both Front Wheels

• Use the 21mm deep socket and 1/2-inch-drive breaker bar to remove the wheel nuts.
• Remove both front wheels and place them flat away from the work area.
• Slide one wheel beneath the side of your Pathfinder as an additional safety measure.

Step 4: Inspect the Brakes

• Use non-chlorinated brake cleaner and the nylon brake-cleaning brush to remove loose dust from the caliper area.
• Inspect the rotor for deep grooves, blue heat spots, cracks, or a pronounced outer lip.
• Inspect the rubber brake hose for cracks, wetness, or bulges. Stop the repair if the hose is damaged or leaking.
• If a rotor is below its stamped minimum thickness, replace both front rotors before fitting the new pads.

Step 5: Remove the Brake Caliper

• The slide pins allow the caliper to move evenly as the brakes apply.
• Use the 14mm socket and 3/8-inch-drive ratchet to remove the upper and lower caliper slide-pin bolts.
• If a slide pin turns, hold its flat section with the 19mm combination wrench while loosening the bolt.
• Lift the caliper straight away from the rotor. Do not twist or pull the brake hose.
• Use the mechanic’s wire hanger to suspend the caliper securely from the suspension.

Step 6: Remove the Old Pads and Hardware

• Use the flat-blade screwdriver to carefully slide the inner and outer pads out of the caliper bracket.
• Use the flat-blade screwdriver to remove the stainless pad-support clips from the bracket.
• Note the orientation of the wear indicator before discarding the old pads.
• Use brake cleaner and the nylon brake-cleaning brush to clean the pad-contact areas.
• Do not remove the large caliper-bracket bolts for a pad-only replacement.

Step 7: Check and Lubricate the Slide Pins

• Pull each slide pin from its rubber boot by hand.
• Wipe the pins clean and inspect them for rust, scoring, or binding.
• Apply a thin coating of high-temperature silicone brake grease to each pin by hand.
• Reinstall each pin into its original position and confirm it slides freely.
• Ensure each rubber boot seats completely around its pin.
• Use only silicone-safe grease on rubber boots.

Step 8: Compress the Caliper Pistons

• Place an old brake pad across both caliper pistons.
• Use the dual-piston brake caliper compression tool to push both pistons inward slowly and evenly.
• Watch the brake-fluid reservoir while compressing the pistons. Use the brake-fluid syringe if the level approaches the reservoir opening.
• Stop if a piston will not retract smoothly. Forcing a seized piston can damage the caliper.
• Do not use the flat-blade screwdriver directly against the piston faces or rubber seals.

Step 9: Install the New Hardware and Pads

• Press the new front brake pad hardware clips into the caliper bracket by hand.
• Apply a very thin layer of high-temperature silicone brake grease to the pad ears where they touch the hardware.
• Apply a thin layer to the metal backs of the pads only where they contact the caliper or piston.
• Install the inner and outer pads in the same orientation as the originals.
• Never place grease on the pad friction material or rotor surface.
• New pads should slide without being forced.

Step 10: Reinstall the Caliper

• Remove the caliper from the mechanic’s wire hanger and position it over the new pads.
• Make sure the brake hose is not twisted.
• Start both slide-pin bolts by hand to prevent cross-threading.
• Use the 14mm socket and 3/8-inch-drive ratchet to seat the bolts.
• If needed, hold the slide pin with the 19mm combination wrench.
• Use the 14mm socket and 1/2-inch-drive torque wrench to tighten both slide-pin bolts to 43 Nm (32 ft-lbs).

Step 11: Repeat on the Opposite Side

• Repeat Steps 4 through 10 on the other front wheel using the same listed tools.
• Confirm both calipers are secure and both brake hoses follow their original routing.
• Use brake cleaner and the nylon brake-cleaning brush to remove any grease or fingerprints from the rotor faces.

Step 12: Reinstall the Wheels

• Install each wheel and start all wheel nuts by hand.
• Use the 21mm deep socket and 3/8-inch-drive ratchet to snug the nuts in a crisscross pattern.
• Use the floor jack to raise your Pathfinder slightly, remove the jack stands, and lower it until the tires touch the ground.
• Use the 21mm deep socket and 1/2-inch-drive torque wrench to tighten the wheel nuts in a crisscross pattern to 113 Nm (83 ft-lbs).

✅ After Repair

• ✅ Before starting the engine, press and release the brake pedal several times until it feels firm. The first few presses may travel farther than normal.
• ✅ Check the brake-fluid reservoir. Add fresh DOT 3 brake fluid only if the level is below MIN; do not overfill it.
• ✅ Start the engine and hold firm pressure on the brake pedal for 30 seconds. The pedal should remain firm and should not slowly sink.
• ✅ Inspect around both front calipers for leaking fluid or loose components.
• ✅ Test the brakes at walking speed in a clear, safe area before entering traffic.
• ✅ Bed in the pads by making 6-10 moderate stops from approximately 50 km/h to 10 km/h. Avoid coming to a complete stop while the brakes are very hot.
• ✅ Drive for 5-10 minutes afterward with minimal braking so the brakes can cool.
• ✅ Avoid hard braking for the first 300-500 km unless required for safety.
• ✅ Recheck the wheel-nut torque after approximately 80-160 km.
