🔧 Elantra - Front Brake Pads & Rotor Replacement

You’ll remove the front calipers, swap in new rotors, and install new brake pads with fresh hardware. This restores braking performance and eliminates pulsation or grinding caused by worn pads or warped rotors.

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

⚠️ Safety & Precautions

• 🛑 Work on level ground and use jack stands—never rely on a floor jack alone.
• 🧤 Brakes create dust—wear gloves and safety glasses; avoid breathing dust.
• 🔥 Brakes can be hot—let everything cool before starting.
• 🧷 Do not let the caliper hang by the brake hose—support it with a hanger.
• 🚫 Do not press the brake pedal with the caliper removed.
• 🔋 Battery disconnect is not required for this job.

📋 Before You Begin

• 🅿️ Park on level ground, shift to P, and set the parking brake.
• 🧱 Chock the rear wheels using wheel chocks.
• 🧴 Open the hood and locate the brake fluid reservoir. If it’s near the MAX line, remove a little fluid (so it won’t overflow when compressing pistons).
• 🛞 Loosen the front lug nuts 1/2 turn with a 21mm socket and breaker bar before lifting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Lift the front using a floor jack at the front jacking point.
• Set the car down onto jack stands at the proper support points.
• Remove the wheels using a 21mm socket.

Step 2: Remove the caliper (the clamp that squeezes the pads)

• Turn the steering wheel to give more working room (left side: turn wheel right; right side: turn wheel left).
• Remove the two caliper slide-pin bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket and support it with a caliper hanger hook or bungee cord.
• Tip: Hang it from the spring, not the hose.

Step 3: Remove the old pads and hardware

• Slide the brake pads out by hand. If stuck, gently pry with a flat screwdriver.
• Remove the stainless hardware clips from the bracket.
• Clean the bracket pad “lands” (where the clips sit) with brake cleaner spray and a wire brush.

Step 4: Remove the caliper bracket

• Remove the two bracket bolts using a 17mm socket and breaker bar.
• Set the bracket aside.
• On reassembly: Torque to 78-88 Nm (58-65 ft-lbs).

Step 5: Remove the rotor

• If equipped with a rotor retaining screw, remove it with a Phillips screwdriver.
• Pull the rotor off. If it’s stuck, tap the rotor hat with a rubber mallet to break it free.
• Clean the hub face (where the rotor sits) with a wire brush, then spray with brake cleaner spray.
• Apply a very thin film of anti-seize compound to the hub face to help prevent future sticking.

Step 6: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray and wipe clean (removes packing oil).
• Install the rotor onto the hub. If it has a retaining screw, reinstall it with a Phillips screwdriver (snug only).

Step 7: Reinstall the caliper bracket with new hardware clips

• Install the new hardware clips onto the bracket.
• Reinstall the bracket bolts using a 17mm socket and ratchet.
• Torque to 78-88 Nm (58-65 ft-lbs).

Step 8: Service slide pins (important for even pad wear)

• Pull the slide pins out of the bracket by hand (they’re the smooth pins the caliper “floats” on).
• Wipe them clean and apply a thin coat of high-temp silicone brake grease.
• Reinsert pins and make sure the rubber boots seat all the way.

Step 9: Install the new brake pads

• Apply a light smear of high-temp silicone brake grease to the pad ears (the ends that touch the clips).
• Slide the pads into the bracket until they move freely.
• Tip: Pads should slide easily by hand.

Step 10: Compress the caliper piston

• Place an old pad against the piston face.
• Use a C-clamp (6") to slowly press the piston back into the caliper.
• Watch the brake fluid reservoir while compressing; don’t let it overflow.
• Tip: Go slow to avoid seal damage.

Step 11: Reinstall the caliper

• Set the caliper over the new pads.
• Install the slide-pin bolts using a 14mm socket and ratchet.
• Torque to 22-25 Nm (16-18 ft-lbs).

Step 12: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread lug nuts.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a torque wrench and 21mm socket.
• Torque to 90-110 Nm (66-81 ft-lbs).

✅ After Repair

• 🦶 Pump the brake pedal 8-15 times until it feels firm (this seats the pistons against the pads).
• 🧴 Check brake fluid level and top off with DOT 3 or DOT 4 if needed.
• 🔍 Check for leaks, and confirm the wheels spin freely with no heavy drag.
• 🛣️ Bed-in the pads: make 6-8 medium stops from ~40 mph down to ~10 mph, then drive a few minutes to cool (avoid hard stops while stopped).
