⚠️ Safety & Precautions

• ⚠️ Work on level ground and support your Frontier with jack stands. Never rely on a jack alone.
• ⚠️ Wear safety glasses and gloves. Brake dust and rust particles can irritate your eyes and skin.
• ⚠️ Do not press the brake pedal while the caliper is removed.
• ⚠️ Brake parts get very hot after driving. Let everything cool before starting.
• ⚠️ Open the brake fluid reservoir cap before compressing the caliper piston, but do not let dirt enter the reservoir.
• ⚠️ Battery disconnect is not required for this front brake service.

📋 Before You Begin

• 🅿️ Park your Frontier on level ground and shift into Park.
• 🧱 Place wheel chocks behind the rear wheels. Wheel chocks are wedge blocks that stop the truck from rolling.
• 🛞 Slightly loosen the front lug nuts with a 21mm lug nut socket before lifting the truck.
• 🧴 Open the hood and locate the brake fluid reservoir. Clean around the cap with a shop rag, then loosen the cap.
• 📏 If the brake fluid level is already at the MAX line, remove a small amount with a clean suction tool before compressing the caliper piston to prevent overflow.
• 🔌 No infotainment menu, scan tool, EPB retraction, ADAS calibration, or battery registration is needed for this front brake job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use a 21mm lug nut socket and 1/2-inch breaker bar to loosen each front lug nut about 1/2 turn.
• Do not remove the lug nuts yet. The tire should stay on the ground while breaking them loose.
• Loosen first, lift second.

Step 2: Lift and Support the Front of the Truck

• Use a floor jack rated 3-ton minimum under the front center crossmember to raise the front of your Frontier.
• Place jack stands rated 3-ton minimum under the left and right front frame support points.
• Slowly lower the truck onto the jack stands and gently shake the truck to confirm it is stable.
• Keep the floor jack lightly touching the lift point as a backup.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket and 3/8-inch ratchet to remove the loosened lug nuts.
• Remove both front wheels and set them flat on the ground.
• Slide one wheel under the frame as an extra safety backup.

Step 4: Inspect the Brake Assembly

• Put on safety glasses and nitrile gloves.
• Look at the brake caliper, brake hose, rotor, and pad thickness before removal.
• The caliper is the clamp-shaped part that squeezes the pads against the rotor.
• If the brake hose is cracked, leaking, or twisted, do not continue until that is repaired.

Step 5: Remove the Caliper Slide Pin Bolts

• Use a 14mm socket and 3/8-inch ratchet to remove the two caliper slide pin bolts from the back of the caliper.
• Slide pins let the caliper move evenly as the pads wear.
• Pull the caliper away from the rotor carefully.
• Do not let the caliper hang by the brake hose.

Step 6: Support the Caliper

• Use a bungee cord to hang the caliper from the front coil spring or upper suspension area.
• Make sure the rubber brake hose is not stretched, kinked, or twisted.
• Protect the hose from stress.

Step 7: Remove the Old Brake Pads

• Use a flat-blade screwdriver to gently pry the old brake pads out of the caliper bracket.
• Note the position of any wear indicator clips before removing the pads.
• The wear indicator is a small metal tab that squeals when pads are worn.

Step 8: Remove the Caliper Bracket

• Use a 19mm socket and 1/2-inch breaker bar to remove the two caliper bracket bolts.
• Hold the bracket firmly while removing the last bolt.
• Set the bracket on a clean surface.

Step 9: Remove the Old Rotor

• Pull the rotor straight off the wheel hub by hand.
• If it is stuck from rust, lightly tap around the rotor hat with the handle of a 1/2-inch breaker bar.
• Do not hit the wheel studs.
• The rotor hat is the raised center section of the brake rotor.

Step 10: Clean the Hub Face

• Use a wire brush to clean rust and scale from the wheel hub face.
• Spray the area with brake parts cleaner spray and wipe it with shop rags.
• A clean hub helps the new rotor sit flat and prevents brake vibration.
• Clean metal makes smooth brakes.

Step 11: Prepare and Install the New Rotor

• Spray both sides of the new rotor with brake parts cleaner spray.
• Wipe the rotor dry with shop rags.
• Slide the new rotor onto the hub.
• Thread one lug nut on by hand using the 21mm lug nut socket to hold the rotor in place temporarily.

Step 12: Service the Caliper Bracket

• Use a flat-blade screwdriver to remove the old stainless brake hardware clips from the caliper bracket.
• Use a wire brush to clean the areas where the clips sit.
• Install the new clips from the front brake hardware kit by hand.
• Apply a thin layer of disc brake caliper slide pin grease to the pad contact points on the clips.
• Do not get grease on the rotor or pad friction surfaces.

Step 13: Reinstall the Caliper Bracket

• Position the caliper bracket over the rotor.
• Start both bracket bolts by hand to avoid cross-threading.
• Use a 19mm socket and 1/2-inch torque wrench to tighten the caliper bracket bolts.
• Torque to 152 Nm (112 ft-lbs)

Step 14: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use a brake caliper piston compressor tool to slowly push the piston fully back into the caliper.
• The piston is the round metal part that pushes the inner brake pad.
• Watch the brake fluid reservoir while compressing. Use shop rags to catch any overflow.
• If brake fluid spills, clean it immediately because it can damage paint.

Step 15: Install the New Brake Pads

• Install the new front brake pads into the caliper bracket by hand.
• Make sure the pad friction material faces the rotor.
• If the pad set has a wear indicator, install it in the same position as the original pad.
• The pads should slide smoothly in the new hardware clips.

Step 16: Reinstall the Caliper

• Remove the bungee cord and carefully place the caliper over the new pads.
• Start both caliper slide pin bolts by hand.
• Use a 14mm socket and 3/8-inch torque wrench to tighten the slide pin bolts.
• Torque to 32 Nm (24 ft-lbs)

Step 17: Repeat on the Other Side

• Repeat Steps 5 through 16 on the other front brake assembly.
• Always replace front brake pads and rotors in pairs.
• This keeps braking even from side to side.

Step 18: Reinstall the Wheels

• Remove the temporary lug nut holding each rotor using the 21mm lug nut socket.
• Install both front wheels.
• Thread all lug nuts by hand first.
• Snug the lug nuts in a star pattern using the 21mm lug nut socket and 3/8-inch ratchet.

Step 19: Lower the Truck and Torque the Lug Nuts

• Use the floor jack rated 3-ton minimum to raise the truck slightly off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower the truck until the tires touch the ground fully.
• Use a 21mm lug nut socket and 1/2-inch torque wrench to tighten the lug nuts in a star pattern.
• Torque to 133 Nm (98 ft-lbs)

Step 20: Pump the Brake Pedal

• Before driving, press the brake pedal slowly 5-10 times until it feels firm.
• This moves the caliper pistons back into normal position against the new pads.
• If the pedal stays soft or sinks, do not drive the truck.

Step 21: Check Brake Fluid Level

• Use safety glasses and check the brake fluid reservoir level.
• Add DOT 3 brake fluid if needed to bring the level between MIN and MAX.
• Reinstall the brake fluid reservoir cap tightly by hand.
• Wipe any spilled fluid with shop rags.

✅ After Repair

• ✅ Start your Frontier and press the brake pedal again. It should feel firm.
• ✅ Check around both front calipers for leaks before driving.
• ✅ Perform a slow test in a safe area. Confirm the truck stops straight without grinding or pulling.
• ✅ Bed in the new pads and rotors: make 8-10 moderate stops from about 30 mph to 5 mph, allowing a short cool-down between stops.
• ✅ Avoid hard emergency-style braking for the first 200 miles unless necessary.
• ✅ Recheck lug nut torque after 25-50 miles using a 21mm lug nut socket and 1/2-inch torque wrench.
