🔧 Altima - Front Brake Pad Replacement

You’ll be removing the front wheel, swinging the brake caliper out of the way, and swapping in new pads (plus hardware) on your Altima. This restores safe stopping power and prevents rotor damage when pads get thin.

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

⚠️ Safety & Precautions

• 🛑 Support the car on jack stands—never rely on a jack alone.
• 🧤 Brake dust is harmful; wear nitrile gloves and a dust mask, and avoid blowing dust with compressed air.
• 🔥 Brakes can be hot; let everything cool before starting.
• 🧪 Brake fluid damages paint; keep a rag handy and wipe spills immediately.
• 🔩 Do one side at a time so you can reference the other side if needed.

📋 Before You Begin

• Park on level ground, turn the engine off, and place wheel chocks behind the rear wheels.
• Open the hood and locate the brake fluid reservoir. If it’s near the “MAX” line, use a turkey baster to remove a little fluid (compressing the caliper piston can make the level rise).
• Loosen the front wheel lug nuts slightly while the car is still on the ground (do not remove them yet).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the front wheel

• Use a floor jack to lift the front of the car at the proper jacking point.
• Set the car securely on jack stands.
• Use a 21mm socket and ratchet to remove the lug nuts, then remove the wheel.

Step 2: Locate the caliper and pads

• Turn the steering wheel to give yourself room (turn left for the right side, right for the left side).
• Identify the brake caliper (the clamp) and the caliper bracket (the larger mount holding the pads).

Step 3: Remove the caliper slide pin bolts

• Use a 14mm socket and ratchet to remove the two caliper slide pin bolts (top and bottom).
• If the slide pin spins, hold it gently with a wrench while you loosen the bolt (don’t crush the rubber boot).

Step 4: Hang the caliper (do not let it dangle)

• Carefully lift the caliper off the bracket.
• Support the caliper with a wire hook or bungee cord so it does not pull on the brake hose.

Step 5: Remove old pads and hardware

• Pull the inner and outer pads out of the bracket by hand.
• Use a flathead screwdriver to remove the old abutment clips (metal hardware) from the bracket.
• Spray the bracket pad lands (where clips sit) with brake cleaner spray, then scrub with a wire brush until clean and smooth.

Step 6: Compress the caliper piston

• Place the old inner pad against the piston face.
• Use a brake caliper piston compressor tool (specialty) to slowly push the piston fully back into the caliper. (This tool presses the piston straight in so the new thicker pads fit.)
• Go slowly and watch the brake fluid reservoir level so it doesn’t overflow.
• Slow, steady pressure prevents seal damage.

Step 7: Lubricate slide pins and install new hardware

• Pull each slide pin out one at a time and wipe it clean with shop rags.
• Apply a thin, even coat of brake caliper slide pin grease (silicone-based), then reinstall each pin and make sure it moves smoothly.
• Install the new abutment clips from the hardware kit onto the bracket.

Step 8: Install new brake pads

• Install the new inner and outer pads into the bracket.
• If your pad set includes a wear indicator “squealer,” match it to the original pad location on that side.
• Apply brake parts lubricant (anti-squeal) in a thin layer only on pad backing/ears where they contact the clips/bracket—do not get any on the pad friction material or rotor.

Step 9: Reinstall the caliper and torque bolts

• Place the caliper back over the new pads.
• Start both slide pin bolts by hand to avoid cross-threading.
• Use a 14mm socket and torque wrench to tighten the caliper slide pin bolts: Torque to 25 Nm (18 ft-lbs).

Step 10: Reinstall the wheel and torque lug nuts

• Put the wheel back on and hand-thread the lug nuts.
• Lower the car off the jack stands using the floor jack.
• Use a torque wrench with a 21mm socket to tighten lug nuts in a star pattern: Torque to 113 Nm (83 ft-lbs).

Step 11: Repeat on the other front side

• Repeat Steps 1–10 for the other front wheel.

✅ After Repair

• With the engine off, press the brake pedal firmly 8–15 times until it feels solid (this seats the pistons against the new pads).
• Check the brake fluid level and top off only if needed.
• Start the engine and confirm the brake pedal feels normal before driving.
• Perform a pad break-in: make 8–10 moderate stops from ~40 mph down to ~10 mph, allowing a little cooling time between stops. Avoid hard stops for the first 150–200 miles.
• Test drive at low speed first and listen for abnormal grinding or pulling.
