🔧 Elantra - Front Brake Pads & Rotor Replacement

You’ll be removing the front calipers, replacing the brake pads, and swapping the front rotors. New rotors give you a flat, clean surface so the new pads bed-in properly and you avoid vibration or noise.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Support your Elantra with jack stands—never rely on a floor jack alone.
• ⚠️ Brake dust is hazardous—avoid blowing dust; use brake cleaner.
• ⚠️ Don’t let the caliper hang by the brake hose—support it with a hook/strap.
• ⚠️ Watch brake fluid level when compressing pistons; overflow can damage paint.
• ⚠️ Work on a cool brake system—hot rotors/calipers can burn you.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Crack the front lug nuts loose 1/2 turn before lifting (use lug wrench or 21mm socket).
• Open the hood and check the brake fluid reservoir level; you may need to remove a little fluid if it’s near “MAX.”
• Take a photo of pad/clip layout first.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use a floor jack to lift the front at the factory front jacking point.
• Place jack stands under the left and right front pinch welds/subframe support points.
• Give the car a firm push to confirm it’s stable before working.

Step 2: Remove the front wheels

• Remove the lug nuts using a lug wrench or 21mm socket.
• Remove both front wheels and slide them under the car as an extra safety backup.

Step 3: Remove the caliper (do not remove the brake hose)

• Turn the steering wheel to give yourself 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. If it’s tight, gently pry with a flat pry bar.
• Support the caliper with a bungee cord or caliper hook so the hose is not stretched.

Step 4: Remove old pads and hardware

• Slide the pads out by hand (use gloves).
• Remove the stainless pad clips (hardware) from the bracket.
• Clean the bracket pad lands with a wire brush and spray with brake cleaner.

Step 5: Remove the caliper bracket

• Remove the two caliper bracket bolts using a 17mm socket and breaker bar.
• Set the bracket aside.
• When reinstalling later: Torque to 98 Nm (72 ft-lbs).

Step 6: Remove the rotor

• If equipped with a rotor retaining screw, remove it using a Phillips screwdriver.
• Pull the rotor off. If it’s stuck, strike the rotor hat with a rubber mallet to break it free.
• Clean the hub face with a wire brush, then spray with brake cleaner. The hub must be flat and rust-free to prevent vibration.

Step 7: Install the new rotor

• Clean the new rotor friction surfaces with brake cleaner to remove packing oil.
• Install the rotor onto the hub.
• If there was a retaining screw, reinstall it using a Phillips screwdriver (snug only; do not strip it).

Step 8: Prep slide pins and install new hardware

• Pull the caliper slide pins out of the bracket by hand.
• Wipe old grease off and apply a thin coat of brake caliper grease.
• Reinstall slide pins and confirm they move smoothly.
• Install the new pad clips/hardware into the bracket.
• No grease on rotor or pad friction face.

Step 9: Reinstall the bracket

• Position the bracket over the new rotor.
• Install the bracket bolts by hand first, then tighten using a 17mm socket.
• Final tighten with a torque wrench: Torque to 98 Nm (72 ft-lbs).

Step 10: Compress the caliper piston

• Before compressing, check the brake fluid reservoir again (it will rise).
• Use a C-clamp brake piston compressor to slowly push the piston fully back into the caliper.
• Go slow and steady; if it won’t compress smoothly, stop and re-check for binding.

Step 11: Install new pads and reinstall the caliper

• Apply a thin film of brake caliper grease to the pad ears where they contact the clips.
• Install the new pads into the bracket.
• Place the caliper over the pads and align the slide pin bolt holes.
• Install and tighten the slide pin bolts using a 14mm socket.
• Final tighten with a torque wrench: Torque to 28 Nm (21 ft-lbs).

Step 12: Reinstall wheels

• Install wheels and hand-thread lug nuts.
• Lower the car until the tires just touch the ground.
• Tighten lug nuts in a star pattern using a torque wrench: Torque to 90-110 Nm (66-81 ft-lbs).
• Fully lower the vehicle and remove the floor jack and jack stands.

✅ After Repair

• With engine OFF, pump 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 brake fluid if needed.
• Start the engine and confirm the pedal remains firm.
• Test at low speed first. Confirm no pulling, grinding, or warning lights.
• Bed-in the pads: do 8-10 medium stops from ~40 mph down to ~10 mph, allowing light cooling between stops. Avoid hard stops for the first 200 miles.
