🔧 Altima - Front Brake Pad Replacement

You’ll be removing the front wheels, swinging the front brake calipers out of the way, swapping the pad set, and then reassembling everything with the correct torque. This restores safe stopping power and prevents metal-to-metal rotor damage when pads get thin.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands—never rely on a jack alone.
• 🧱 Chock the rear wheels with wheel chocks so the car can’t roll.
• 🔥 Brakes can be hot; let them cool before touching rotors/calipers.
• 🧴 Brake dust is messy—use brake cleaner, not compressed air.
• 🪝 Do not let the caliper hang by the brake hose; support it with a bungee cord.
• 🔋 Battery disconnect is not required for this job.

📋 Before You Begin

• Park on level ground, put the shifter in P, and set the parking brake.
• Place wheel chocks behind both rear wheels.
• Crack the front wheel lug nuts loose 1/4 turn with a 21mm socket and breaker bar before lifting.
• Open the hood and check the brake fluid level in the reservoir; if it’s near “MAX,” be ready to remove a little later (pushing the piston back can raise fluid).
• C-clamp tip: It’s a screw clamp used to push the piston in.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Lift the front of your Altima with a floor jack at the proper front jacking point.
• Set the car down onto jack stands under solid frame/pinch-weld support points.
• Give the car a gentle shake to confirm it’s stable.

Step 2: Remove the front wheels

• Remove all lug nuts using a 21mm socket and ratchet.
• Remove both front wheels and set them aside.

Step 3: Locate the caliper bolts and remove them

• Turn the steering wheel to give yourself more room to work on one side at a time.
• On the back of the caliper, remove the two caliper slide pin bolts using a 14mm socket and ratchet.
• Keep the bolts safe and clean.

Step 4: Swing the caliper up and support it

• Carefully swing the caliper away from the pads/rotor (it pivots off the bracket).
• Support the caliper with a bungee cord so the brake hose is not stretched.

Step 5: Remove the old pads and hardware

• Pull the inner and outer brake pads out of the bracket by hand.
• Remove the pad hardware clips from the bracket using a flat-blade screwdriver.
• Clean the bracket “pad resting areas” with brake parts cleaner spray and a wire brush, then wipe with shop towels.
• Tip: Clean metal helps pads slide freely.

Step 6: Check the rotor and caliper slide pins

• Inspect the rotor face for deep grooves, heavy rust ridges, or blue/purple heat spots.
• Check the caliper slide pins (the pins the caliper moves on). If they’re sticky, they can cause uneven pad wear.
• If you remove a slide pin, clean it with brake parts cleaner spray, wipe with shop towels, then apply a thin coat of brake caliper grease before reinstalling.

Step 7: Install new hardware clips

• Install the new pad hardware clips from the hardware kit onto the caliper bracket by hand (use a flat-blade screwdriver only if needed to fully seat them).
• Apply a very thin film of brake caliper grease where the pad “ears” contact the clips (do not get grease on the pad friction material).

Step 8: Compress the caliper piston

• Place one old brake pad against the caliper piston face.
• Use a C-clamp (6" minimum) to slowly press the piston back into the caliper until it bottoms out.
• Watch the brake fluid reservoir while compressing; if it rises too high, stop and remove a small amount of fluid safely.

Step 9: Install the new pads

• Install the new inner and outer pads into the bracket.
• Make sure the pads sit flat and can slide a little in the clips.

Step 10: Reinstall the caliper and torque the bolts

• Swing the caliper back over the new pads.
• Reinstall the caliper slide pin bolts using a 14mm socket and ratchet.
• Final tighten with a torque wrench: Torque to 26 Nm (19 ft-lbs).

Step 11: Repeat on the other front wheel

• Repeat Steps 3–10 on the other side.
• Work neatly so left/right parts don’t get mixed up.

Step 12: Reinstall wheels and torque lug nuts

• Reinstall both wheels and hand-thread the lug nuts.
• Lower the car to the ground using the floor jack.
• Tighten lug nuts in a star pattern with a torque wrench: Torque to 113 Nm (83 ft-lbs).

✅ After Repair

• Before driving, press the brake pedal 10–15 times until it feels firm. This seats the pistons against the new pads.
• Check the brake fluid level and top off with DOT 3 only if needed.
• Look around each caliper for any leaks or anything left loose.
• Do a cautious test drive: start with low-speed stops in a safe area.
• Pad break-in: make 6–10 moderate stops from ~40 to ~10 mph, with short cool-down driving between stops. Avoid hard panic stops for the first ~200 miles.
