⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never work under a vehicle supported by only a jack.
• ⚠️ Use jack stands. Jack stands are fixed supports that hold the vehicle safely after lifting.
• ⚠️ Front brakes can be very hot after driving. Let them cool before touching anything.
• ⚠️ Brake dust is harmful. Do not blow it with compressed air; use brake cleaner instead.
• ⚠️ Brake fluid can damage paint. Wipe spills immediately with a clean rag and water.
• ⚠️ Battery disconnect is not required for this front brake repair.

📋 Before You Begin

• 🚗 Park your Tucson on level ground and shift the transmission into Park.
• 🧱 Place wheel chocks behind both rear tires. Wheel chocks are blocks that stop the vehicle from rolling.
• 🅿️ Set the parking brake before lifting the front of the vehicle.
• 🧴 Open the hood and locate the brake fluid reservoir. It is the small plastic tank near the driver-side rear of the engine bay.
• 👀 Check the brake fluid level. If it is at the MAX line, remove a small amount with a clean suction tool before compressing the caliper pistons.
• 📌 Your Tucson uses a normal hydraulic front brake caliper. No scan tool or electronic parking brake service mode is needed for the front brakes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use the 21mm lug nut socket and 1/2-inch breaker bar to loosen each front wheel lug nut about half a turn.
• Do this while the tires are still on the ground so the wheels do not spin.
• Do not remove the nuts yet.

Step 2: Lift and Support the Front of the Tucson

• Use the floor jack rated 3-ton minimum at the front center lifting point or approved front pinch weld area.
• Raise the front of your Tucson high enough for both front wheels to clear the ground.
• Place jack stands rated 3-ton minimum under the approved front support points.
• Gently lower the vehicle onto the jack stands using the floor jack.
• Give the vehicle a light shake by hand. It should feel stable before you continue.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket and 3/8-inch ratchet to remove the loosened lug nuts.
• Remove both front wheels and place them flat under the side of the vehicle as an extra safety backup.

Step 4: Inspect the Brake Assembly

• Put on safety glasses, nitrile gloves, and a dust mask.
• Look at the caliper, pads, rotor, and brake hose before taking anything apart.
• The caliper is the clamp-shaped part that squeezes the brake pads against the rotor.
• Spray dusty areas with brake cleaner spray and wipe with shop rags.

Step 5: Remove the Lower Caliper Bolt

• Use a 14mm socket and 3/8-inch ratchet to remove the lower caliper slide bolt.
• If the slide pin spins, hold the pin with a 17mm box-end wrench while loosening the bolt with the 14mm socket.
• A slide pin is a smooth pin that lets the caliper move in and out evenly.

Step 6: Swing the Caliper Up

• Use the small pry bar 12-inch gently between the caliper and old pad if the caliper is tight.
• Swing the caliper upward away from the rotor.
• Support the caliper with the bungee cord 18-inch from the strut spring.
• Do not let the caliper hang by the rubber brake hose.

Step 7: Remove the Old Brake Pads and Hardware

• Pull the old inner and outer brake pads out by hand.
• Use the small pry bar 12-inch if the pads are stuck in the bracket.
• Remove the old metal pad clips from the caliper bracket by hand or with the small pry bar 12-inch.
• The pad clips are thin stainless pieces that help the pads slide quietly and evenly.

Step 8: Remove the Caliper Bracket

• Use the 17mm socket and 1/2-inch breaker bar to remove the two caliper bracket bolts.
• Remove the caliper bracket from the steering knuckle.
• Set the bracket on a clean surface.

Step 9: Remove the Front Rotor

• Use the Phillips #3 screwdriver to remove the rotor retaining screw if equipped.
• If the screw is stuck, use the impact screwdriver with Phillips #3 bit. An impact screwdriver twists when struck and helps loosen stuck screws.
• Pull the rotor straight off the hub.
• If the rotor is rusted on, tap the rotor hat area with the rubber mallet 16-ounce.
• Do not hit the wheel studs with the mallet.

Step 10: Clean the Hub Face

• Use the wire brush to clean rust and dirt from the wheel hub face.
• Spray the hub with brake cleaner spray and wipe it dry with shop rags.
• The hub face must be clean so the new rotor sits flat and does not cause brake vibration.

Step 11: Prepare and Install the New Rotor

• Spray both sides of the new rotor with brake cleaner spray.
• Wipe both sides dry with shop rags.
• Slide the new rotor onto the hub by hand.
• Install the rotor retaining screw with the Phillips #3 screwdriver if equipped.
• Torque to 4-6 Nm (35-53 in-lbs) if a retaining screw is installed.

Step 12: Service the Caliper Bracket

• Use the wire brush to clean the pad contact areas on the caliper bracket.
• Spray the bracket with brake cleaner spray and dry it with shop rags.
• Install the new front brake hardware kit clips by hand.
• Apply a thin film of brake caliper slide pin grease only where the pads touch the clips.
• Do not get grease on the rotor or pad friction surface.

Step 13: Check and Grease the Slide Pins

• Pull each slide pin out of the caliper bracket by hand.
• Wipe old grease off with shop rags.
• Inspect the rubber boots for tears.
• Apply fresh brake caliper slide pin grease to the pins.
• Push the slide pins back into the bracket by hand until they move smoothly.

Step 14: Reinstall the Caliper Bracket

• Place the caliper bracket over the new rotor.
• Start both bracket bolts by hand first to avoid cross-threading.
• Use the 17mm socket and torque wrench 10-150 ft-lbs to tighten the bracket bolts.
• Torque to 88-98 Nm (65-72 ft-lbs).

Step 15: Install the New Brake Pads

• Slide the new inner and outer brake pads into the caliper bracket by hand.
• Make sure the friction material faces the rotor.
• The pads should move slightly by hand. If they are jammed, remove them and recheck the clips and bracket cleaning.
• Pads should slide, not rattle.

Step 16: Compress the Caliper Piston

• Check the brake fluid reservoir under the hood before compressing the piston.
• Place one old brake pad against the caliper piston.
• Use the C-clamp 6-inch or brake caliper piston compression tool to slowly push the piston fully into the caliper.
• The piston is the round metal piece inside the caliper that pushes the brake pad.
• Compress slowly so brake fluid does not overflow from the reservoir.

Step 17: Reinstall the Caliper

• Remove the bungee cord 18-inch and swing the caliper down over the new pads.
• Start the lower caliper slide bolt by hand.
• Use the 14mm socket and torque wrench 10-150 ft-lbs to tighten the caliper slide bolt.
• If the slide pin spins, hold it with the 17mm box-end wrench.
• Torque to 22-32 Nm (16-24 ft-lbs).

Step 18: Repeat on the Other Front Side

• Repeat Steps 4 through 17 on the opposite front wheel.
• Always replace front pads and rotors in pairs so braking stays even.

Step 19: Reinstall the Wheels

• Install each wheel by hand.
• Thread all lug nuts by hand first.
• Use the 21mm lug nut socket and 3/8-inch ratchet to snug the lug nuts in a star pattern.
• A star pattern means tightening across the wheel, not around in a circle.

Step 20: Lower and Torque the Wheels

• Use the floor jack rated 3-ton minimum to lift the front slightly off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower your Tucson until the tires touch the ground.
• Use the 21mm lug nut socket and torque wrench 10-150 ft-lbs to tighten lug nuts in a star pattern.
• Torque to 88-108 Nm (65-80 ft-lbs).

Step 21: Pump the Brake Pedal

• Sit in the driver seat and press the brake pedal slowly several times.
• The pedal may go low at first. Keep pumping until it feels firm.
• This moves the caliper pistons back against the new brake pads.
• Do not drive until the pedal feels firm.

Step 22: Check Brake Fluid Level

• Open the hood and check the brake fluid reservoir.
• Add DOT 3 or DOT 4 brake fluid only if the level is below the MIN mark.
• Use shop rags to wipe any spills right away.
• Install the reservoir cap securely.

✅ After Repair

• ✅ Start your Tucson and press the brake pedal again. It should feel firm and steady.
• ✅ With the vehicle still parked, shift to Drive and Reverse briefly while holding the brake to confirm normal stopping feel.
• ✅ Perform a slow test drive in a safe area. Start at 5-10 mph and make gentle stops.
• ✅ Bed in the new pads if the pad manufacturer recommends it. Bedding-in means making controlled stops to transfer an even layer of pad material to the rotor.
• ✅ For a simple bedding method, make 8-10 moderate stops from about 30 mph to 5 mph, allowing a short cooling period between stops.
• ✅ Avoid hard braking for the first 200 miles unless it is an emergency.
• ✅ Recheck lug nut torque after 25-50 miles using the 21mm lug nut socket and torque wrench 10-150 ft-lbs.
