📋 Before You Begin

• 📍 Park your Pathfinder on firm, level ground. Shift to Park, apply the parking brake, and switch off the ignition.
• 🛞 Place wheel chocks behind both rear tires.
• 🧊 Allow the brakes to cool completely before touching them.
• 🧰 Open the hood and inspect the brake-fluid reservoir. If it is near the MAX line, use the brake-fluid syringe to remove a small amount before compressing the caliper pistons.
• 🔩 A breaker bar is a long, non-ratcheting handle that provides extra leverage for tight bolts.
• 🔧 A caliper hanger is a strong hook that supports the caliper without pulling on its brake hose.
• 📱 No infotainment setting, scan-tool command, coding, or electronic parking-brake service mode is required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Use the 21mm deep socket and 1/2-inch breaker bar to loosen each front wheel nut about one-half turn.
• Do not remove the nuts while your Pathfinder is still on the ground.

Step 2: Raise and Support the Front

• Use the 3-ton floor jack at the reinforced front-center lifting point on the front subframe.
• Place the 3-ton jack stands beneath the reinforced left and right front support points.
• Lower the vehicle gently onto the stands. Give it a light push to verify that it is stable.
• Keep the floor jack lightly touching the lifting point as an additional safeguard.

Step 3: Remove the Front Wheels

• Use the 21mm deep socket and 1/2-inch breaker bar to remove the wheel nuts.
• Remove both front wheels and slide them beneath the side rails as an additional safety measure.
• Work on one side at a time so the assembled side remains available as a reference.

Step 4: Create Space for the New Pads

• Turn the steering wheel so the caliper on the side being serviced faces outward.
• Use the large flat-blade screwdriver between the old inboard pad and rotor to push the caliper pistons inward slightly.
• Apply slow, steady pressure. Watch the brake-fluid reservoir and use the brake-fluid syringe if the level approaches MAX.
• Slow pressure protects the piston seals.

Step 5: Remove the Brake Caliper

• Use the 14mm socket, 3/8-inch ratchet, and 6-inch extension to remove the upper and lower caliper slide-pin bolts.
• Lift the caliper from the pads. Use the brake caliper hanger to suspend it from the strut spring.
• Inspect the rubber brake hose for cracks, swelling, twisting, or wetness.
• Do not disconnect the brake hose.

Step 6: Remove the Old Pads and Hardware

• Pull the inner and outer pads from the caliper bracket by hand.
• Remove the stainless-steel pad clips from the bracket using the large flat-blade screwdriver.
• Note the position of each wear indicator before removing the old pads.
• Use the small nylon detailing brush and brake cleaner to remove loose debris without creating airborne dust.

Step 7: Remove the Caliper Bracket

• Use the 22mm socket, 1/2-inch breaker bar, and 6-inch extension to remove the two caliper-bracket bolts.
• Hold the bracket securely because it is heavy.
• Inspect the slide-pin boots for splits or looseness.

Step 8: Remove the Old Rotor

• Pull the rotor straight off the wheel hub.
• If rust holds it in place, spray brake cleaner around the hub area and strike the rotor hat between the wheel studs with the rubber mallet.
• Do not strike the wheel studs or the braking surface needed for comparison.
• Use the hand wire brush to clean rust from the hub face and center pilot.
• Wipe the hub with brake cleaner and disposable shop towels. The new rotor must sit completely flat.

Step 9: Prepare and Install the New Rotor

• Use brake cleaner and disposable shop towels to clean both friction surfaces of the new rotor.
• Install the rotor over the wheel studs and seat it against the hub.
• Thread one wheel nut on by hand to hold the rotor in position. Do not tighten it with a tool.

Step 10: Service the Caliper Bracket

• Use the hand wire brush to clean the bracket channels where the stainless-steel pad clips sit.
• Install the new pad hardware by hand. Make sure every clip is fully seated.
• Remove one slide pin at a time by hand, wipe it with a disposable shop towel, and inspect it for rust or scoring.
• Apply a thin coat of high-temperature silicone brake grease to the smooth portion of each slide pin, then reinstall it by hand.
• Do not use petroleum grease because it can damage the rubber boots.
• Confirm that both slide pins move smoothly and their boots are properly seated.

Step 11: Reinstall the Caliper Bracket

• Position the bracket over the new rotor and install both bracket bolts by hand.
• Use the 22mm socket and 1/2-inch torque wrench to tighten both bolts to 185 Nm (136 ft-lbs).
• Do not apply grease or anti-seize to the bolt threads.

Step 12: Install the New Brake Pads

• Apply a very thin layer of high-temperature silicone brake grease to the pad ears where they touch the stainless-steel clips.
• Apply a thin layer to the metal pad backing plates where they contact the caliper and pistons.
• Keep all grease away from the rotor and pad friction material.
• Install the inner and outer pads by hand with the wear indicators positioned the same way as the original pads.
• Confirm that the pads slide smoothly in the bracket without binding.

Step 13: Compress the Caliper Pistons

• Place an old brake pad across both caliper pistons.
• Use the brake caliper piston compressor to push both pistons fully and evenly into the caliper.
• Monitor the reservoir while compressing the pistons. Use the brake-fluid syringe if the fluid approaches MAX.
• Stop if either piston tilts, binds, or leaks.

Step 14: Reinstall the Brake Caliper

• Remove the brake caliper hanger and lower the caliper over the new pads.
• Make sure the brake hose is not twisted and both slide-pin boots remain properly seated.
• Install the two slide-pin bolts by hand.
• Use the 14mm socket and 3/8-inch torque wrench to tighten the slide-pin bolts to 32 Nm (24 ft-lbs).
• Remove the temporary wheel nut using the 21mm deep socket and 1/2-inch breaker bar.

Step 15: Repeat on the Other Side

• Repeat Steps 4 through 14 on the opposite front brake using the same listed tools.
• Verify that both sides have new rotors, pads, hardware, and properly torqued fasteners.

Step 16: Reinstall the Wheels

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

Step 17: Restore Brake-Pedal Pressure

• Before starting the engine, press and release the brake pedal slowly several times until it feels firm.
• Use the brake-fluid syringe only if excess fluid must be removed. Keep the reservoir level between MIN and MAX.
• If fluid is needed, add only fresh DOT 3 brake fluid from a sealed bottle.
• Do not drive if the pedal remains soft or sinks toward the floor.

✅ After Repair

• ✅ Start the engine and press the brake pedal. It should remain firm under steady pressure.
• ✅ Check around both front calipers and brake hoses for fluid leaks.
• ✅ Confirm that the brake warning and ABS warning lamps turn off normally.
• ✅ Test the brakes at walking speed in a safe, traffic-free area before normal driving.
• ✅ Follow the brake-pad manufacturer's bedding procedure. If none is supplied, make 6-8 moderate stops from about 50 km/h to 10 km/h without activating ABS, then drive for 10 minutes to cool the brakes.
• ✅ Avoid holding the brake pedal firmly while stopped immediately after bedding because hot pads can transfer material unevenly.
• ✅ Avoid hard braking for the first 300-500 km unless needed for safety.
• ✅ Recheck the wheel-nut torque at 113 Nm (83 ft-lbs) after 80-160 km.
