🔧 Altima - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake caliper and bracket, replace the rotor, then install new pads. This restores safe stopping power and prevents vibration/pulsation from worn or warped rotors.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• ⚠️ Work on level ground; support the car on jack stands—never rely on a jack.
• ⚠️ Brake dust is harmful; avoid blowing dust and use brake cleaner.
• ⚠️ Brakes get hot; let everything cool before touching.
• ⚠️ Do not let the caliper hang by the brake hose; support it with a hook.
• ⚠️ No battery disconnect is required for front brakes on your Altima.

📋 Before You Begin

• Park on level ground, shift to Park, and chock the rear wheels.
• Crack the front lug nuts loose about 1/4 turn using a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir cap (driver side). Loosen the cap slightly so fluid can rise when you push the pistons back.
• If the reservoir is very full, remove a little fluid so it doesn’t overflow when compressing the calipers.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the front wheels

• Lift the front using the floor jack at the proper front jack point.
• Set the car down onto jack stands and give the car a firm shake to confirm it’s stable.
• Remove lug nuts with a 21mm socket and ratchet, then remove both front wheels.

Step 2: Remove the caliper (do not stretch the hose)

• Turn the steering wheel to give yourself room (toward the side you’re working on).
• Remove the 2 caliper slide pin bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket. Use a wire hook or bungee strap to hang it from the strut spring.
• Never hang caliper by hose.

Step 3: Remove the old pads and bracket

• Slide the old brake pads out of the bracket by hand. Use a flathead screwdriver gently if they’re stuck.
• Remove the caliper bracket bolts using a 19mm socket and breaker bar.
• Set the bracket aside where it won’t pull on anything.

Step 4: Remove the rotor

• Pull the rotor straight off the hub.
• If it’s stuck (common), spray the hub area with brake cleaner spray and tap the rotor hat with a dead-blow mallet until it breaks free.

Step 5: Clean the hub and prep the new rotor

• Use a wire brush to clean rust from the hub face (where the rotor sits). A clean hub helps prevent brake vibration.
• Spray the new rotor faces with brake cleaner spray and wipe off the protective oil (it can cause poor braking if left on).

Step 6: Install the new rotor

• Place the new rotor onto the hub.
• To keep it from wobbling while you work, hand-thread one lug nut backward a few turns (use the 21mm socket to snug it lightly).

Step 7: Reinstall the caliper bracket and hardware

• Reinstall the caliper bracket over the rotor and start both bolts by hand.
• Tighten using a 19mm socket and torque wrench: Torque to 108 Nm (80 ft-lbs).
• Install the new pad hardware clips (from your hardware kit) into the bracket by hand. If needed, use a flathead screwdriver to seat them fully.

Step 8: Compress the caliper piston

• Place one old pad against the piston face, then use a C-clamp (6") to slowly push the piston fully back into the caliper.
• A C-clamp is a screw clamp that presses the piston back evenly.
• Watch the brake fluid reservoir while compressing; don’t let it overflow.

Step 9: Install new pads and reinstall the caliper

• Apply a thin film of high-temp silicone brake grease to the pad “ears” where they slide in the clips (do not get grease on the pad friction material).
• Install the new pads into the bracket by hand.
• Set the caliper back over the pads and align the slide pin bolt holes.
• Install and tighten the slide pin bolts using a 14mm socket and torque wrench: Torque to 32 Nm (24 ft-lbs).

Step 10: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a 21mm socket and torque wrench: Torque to 113 Nm (83 ft-lbs).

✅ After Repair

• Pump the brake pedal 10–15 times until it feels firm before starting to drive (this seats the pistons against the new pads).
• Check the brake fluid level and adjust to the MAX line with DOT 3 brake fluid if needed. Tighten the reservoir cap.
• Do a slow test drive in a safe area. Listen for grinding and verify straight, smooth stops.
• Bed-in (break-in) the pads/rotors: make 8–10 medium stops from ~40 mph down to ~10 mph, allowing 30–60 seconds between stops for cooling. Avoid hard panic stops for the first 200 miles.
• Recheck lug nut torque after 50–100 miles using a torque wrench: 113 Nm (83 ft-lbs).
