🔧 Murano - Rear Brake Pad Replacement

Replacing the rear brake pads requires servicing both rear wheels, cleaning the calipers, and carefully pressing the caliper pistons back into their bores. Your Murano uses a mechanically operated parking brake, so no scan-tool retraction or infotainment service mode is required.

Difficulty Level: Beginner–Intermediate | Estimated Time: 1.5–2.5 hours

Assumption: The original rear calipers and brake system remain installed.

⚠️ Safety & Precautions

• 🛑 Work on level, solid ground and chock both front wheels.
• Never work beneath a vehicle supported only by a floor jack.
• Release the parking brake before removing the rear calipers.
• Brake dust can be harmful. Do not blow it away with compressed air.
• Do not press the brake pedal while a caliper is removed.
• Do not allow a caliper to hang from its flexible brake hose.
• Brake fluid damages paint. Clean spills immediately.
• Battery disconnection is not required.

📋 Before You Begin

• Park your Murano on level pavement, shift into Park, and switch off the ignition.
• Release the foot-operated parking brake completely.
• Place wheel chocks firmly against the front and rear of both front tires.
• Open the hood and check the brake-fluid reservoir. If it is near the MAX line, monitor it closely while compressing the pistons.
• A caliper is the clamp-shaped brake component surrounding the rotor.
• An abutment clip is the small stainless-steel clip on which each brake pad slides.
• Complete one rear wheel at a time so the assembled side remains available as a reference.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Rear Wheel Nuts

• Use a 21mm deep socket and 1/2-inch drive breaker bar to loosen each rear wheel nut about one-quarter turn.
• Do not remove the wheel nuts while the tire is still supporting the vehicle.

Step 2: Raise and Support the Rear

• Position the floor jack beneath the specified rear lifting point and raise your Murano.
• Place jack stands beneath the reinforced rear side support points.
• Lower the vehicle gently onto the stands and confirm it is stable.
• Give the body a gentle stability check.

Step 3: Remove the First Rear Wheel

• Use the 21mm deep socket and 1/2-inch drive breaker bar to remove the loosened wheel nuts.
• Remove the wheel and slide it beneath the side of the vehicle as an additional precaution.

Step 4: Inspect the Brake Assembly

• Use the brake rotor micrometer to measure rotor thickness at several points, away from the outer rust ridge.
• Replace or professionally machine the rotor if it is below the minimum thickness stamped on the rotor, deeply scored, cracked, or badly rusted.
• Check the caliper, hose, and piston area for wet brake-fluid leakage. Stop the repair if leakage is present.

Step 5: Remove the Rear Caliper

• Use the 14mm socket and 3/8-inch drive ratchet to remove the upper and lower caliper sliding-pin bolts.
• Lift the caliper away from the pads and rotor.
• Use the 25-pound bungee cord to support the caliper from the suspension.
• Do not twist, stretch, or kink the flexible brake hose.

Step 6: Remove the Old Pads and Clips

• Pull the inner and outer pads from the caliper bracket by hand.
• Use the small flat-blade screwdriver to carefully lift out the old abutment clips.
• Note the position of the wear indicator before removing the old pads, and install the new indicator-equipped pad in the same position.

Step 7: Clean the Caliper Bracket

• Position the drain pan underneath the brake assembly.
• Apply non-chlorinated brake cleaner and use the brake hardware wire brush to clean the pad-contact surfaces.
• Do not grind away bracket metal. Remove only rust and brake residue.
• Install the new abutment clips by hand, using the small flat-blade screwdriver only if gentle seating assistance is needed.

Step 8: Check the Sliding Pins

• Move each caliper sliding pin in and out by hand. It should move smoothly without binding.
• If a pin is dry, remove it by hand, wipe it clean, and apply a thin coat of high-temperature silicone brake lubricant.
• Reinstall the pin into its original location and make sure its rubber boot seats completely.
• Do not use petroleum grease on rubber brake components.

Step 9: Compress the Caliper Piston

• Place one old brake pad against the piston face.
• Use the 6-inch C-clamp or disc-brake piston compressor to press the piston slowly and straight into the caliper.
• Watch the brake-fluid reservoir while compressing the piston. Stop if fluid approaches the top.
• The piston presses straight inward; do not attempt to rotate it.
• Check that the rubber piston boot folds inward cleanly and is not torn or pinched.

Step 10: Install the New Brake Pads

• Apply a very thin film of high-temperature silicone brake lubricant where the pad ears contact the abutment clips.
• Keep lubricant off the rotor and all friction material.
• Install the inner and outer pads by hand in the same orientation as the removed pads.
• Confirm both pads slide freely in the bracket without excessive looseness.

Step 11: Reinstall the Caliper

• Lower the caliper over the new pads without twisting the brake hose.
• Start both sliding-pin bolts by hand to prevent cross-threading.
• Use the 14mm socket and 3/8-inch drive torque wrench to tighten the sliding-pin bolts to 32 Nm (24 ft-lbs).

Step 12: Service the Opposite Rear Brake

• Repeat Steps 3 through 11 on the opposite rear wheel using the same listed tools.
• Always replace rear brake pads as a complete axle set.

Step 13: Reinstall the Rear Wheels

• Install each wheel and start every wheel nut by hand.
• Use the 21mm deep socket and 1/2-inch drive breaker bar to snug the nuts in a crossing pattern.
• Use the floor jack to raise your Murano slightly, remove the jack stands, and lower it completely.
• Use the 21mm deep socket and 1/2-inch drive torque wrench to tighten the wheel nuts in a crossing pattern to 113 Nm (83 ft-lbs).

Step 14: Seat the Brake Pads

• Before moving the vehicle, press and release the brake pedal several times until it feels firm.
• Check the DOT 3 brake-fluid level and keep it between MIN and MAX. Do not overfill it.
• Apply and release the foot-operated parking brake to verify normal operation.

✅ After Repair

• Start your Murano and verify that the red brake warning lamp turns off after releasing the parking brake.
• With the vehicle stationary, hold firm pedal pressure for 30 seconds. The pedal should not slowly sink.
• Perform a low-speed brake test in a clear area before entering traffic.
• Follow the brake-pad manufacturer’s break-in instructions. If none are supplied, make several moderate stops from approximately 50 km/h to 15 km/h, allowing cooling time between stops.
• Avoid hard braking and holding the brake pedal while stopped immediately after bedding the pads.
• After the road test, check for unusual heat, noise, pulling, fluid leakage, or a burning smell.
• Recheck wheel-nut torque to 113 Nm (83 ft-lbs) after approximately 80–160 km.
