This repair replaces the front brake pads and front brake rotors on your Tucson. The pads create the stopping force, and the rotors are the metal discs the pads clamp onto.

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

⚠️ Safety & Precautions

• ⚠️ Work on a cool vehicle. Brake parts can get extremely hot after driving.
• ⚠️ Always support your Tucson with jack stands. Never work under or beside a vehicle supported only by a jack.
• ⚠️ Replace front brake pads as a complete axle set, meaning both left and right front sides together.
• ⚠️ Brake dust can irritate your lungs. Wear a dust mask and avoid blowing dust with compressed air.
• ⚠️ Brake fluid damages paint. Keep the reservoir capped and wipe spills immediately.
• ⚠️ Battery disconnect is not required for this front brake job.

📋 Before You Begin

• 🚗 Park your Tucson on level ground and shift the manual transmission into 1st gear.
• 🧱 Place wheel chocks behind the rear wheels so the vehicle cannot roll.
• 🅿️ Set the parking brake before lifting the front of the vehicle.
• 🧴 Open the hood and locate the brake fluid reservoir. If it is completely full, remove a small amount with a clean towel or fluid-safe suction tool before compressing the calipers.
• 📌 A brake caliper is the clamp-like part that squeezes the pads against the rotor.
• 📌 A rotor is the round metal disc behind the wheel.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use the 21mm lug nut socket and breaker bar 1/2-inch drive to loosen each front lug nut about 1/2 turn.
• Do this while the tires are still touching the ground so the wheels do not spin.
• Loosen only; do not remove yet.

Step 2: Lift and Support the Front

• Use the floor jack to lift the front of your Tucson at the front center lifting point or one side at a time at the pinch weld lift points.
• Place jack stands under the proper side support points.
• Gently lower the vehicle onto the jack stands.
• Push the vehicle lightly by hand to confirm it is stable before removing wheels.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket and ratchet 1/2-inch drive to remove the front lug nuts.
• Remove both front wheels and place them flat under 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, brake hose, pads, and rotor before removing anything.
• Use the brake parts cleaner and shop towels to clean loose dust from the area.
• Do not spray cleaner directly onto rubber brake hoses for long periods.

Step 5: Remove the Caliper Guide Pin Bolts

• Use the 14mm socket and ratchet 3/8-inch drive to remove the two caliper guide pin bolts on the back of the caliper.
• If the guide pin spins, hold the pin with an open-end wrench while removing the bolt with the 14mm socket.
• Set the bolts aside in a clean spot.

Step 6: Remove and Support the Caliper

• Use the flat-blade screwdriver 1/4-inch to gently wiggle the caliper loose if it is stuck.
• Slide the caliper off the rotor.
• Hang the caliper from the strut spring using the brake caliper hanger hook.
• Do not let the caliper hang by the brake hose.

Step 7: Remove the Old Brake Pads

• Pull the old inner and outer brake pads out of the caliper bracket by hand.
• Use the flat-blade screwdriver 1/4-inch only if a pad is stuck.
• Notice the position of any wear indicator clip so the new pad goes in the same orientation.

Step 8: Remove the Caliper Bracket

• Use the 17mm socket and breaker bar 1/2-inch drive to remove the two caliper bracket bolts.
• Remove the caliper bracket from the steering knuckle.
• These bolts are usually tight, so keep the socket straight to avoid rounding the bolt head.

Step 9: Remove the Rotor Retaining Screws

• Use the Phillips #3 screwdriver to remove the rotor retaining screws from the rotor face.
• If the screws are stuck, use the impact screwdriver (specialty). An impact screwdriver turns when struck and helps remove tight screws without stripping them.
• Keep the screws if the new rotors do not include replacements.

Step 10: Remove the Old Rotor

• Pull the rotor straight off the wheel hub by hand.
• If it is rusted on, strike the rotor hat area with the dead blow hammer 24-ounce.
• Do not hit the wheel studs.
• Rotate and tap evenly around the rotor.

Step 11: Clean the Hub Face

• Use the wire brush to clean rust from the wheel hub face.
• Use brake parts cleaner and shop towels to wipe the surface clean.
• This helps the new rotor sit flat and reduces brake vibration.

Step 12: Install the New Rotor

• Clean both sides of the new rotor with brake parts cleaner and shop towels to remove protective oil.
• Slide the new rotor onto the hub.
• Use the Phillips #3 screwdriver to install the rotor retaining screws.
• Torque to 5-8 Nm (44-71 in-lbs).

Step 13: Service the Caliper Bracket

• Use the flat-blade screwdriver 1/4-inch to remove the old pad hardware clips from the caliper bracket.
• Use the wire brush and brake parts cleaner to clean the bracket where the clips sit.
• Install the new clips from the front brake hardware kit by pressing them into the same positions.
• Apply a thin layer of high-temperature brake lubricant where the brake pad ears touch the clips.

Step 14: Check and Grease the Slide Pins

• Pull the slide pins out of the caliper bracket by hand.
• A slide pin lets the caliper move side-to-side as the brakes apply and release.
• Wipe each pin clean with shop towels.
• Apply brake caliper slide pin grease to each pin.
• Push the pins fully back into the bracket and make sure they move smoothly.

Step 15: Reinstall the Caliper Bracket

• Place the caliper bracket over the new rotor.
• Start both bracket bolts by hand to avoid cross-threading.
• Use the 17mm socket and torque wrench 1/2-inch drive to tighten the bracket bolts.
• Torque to 98-118 Nm (72-87 ft-lbs).

Step 16: Install the New Brake Pads

• Slide the new inner and outer pads into the caliper bracket by hand.
• Make sure the friction material faces the rotor.
• Use a light amount of high-temperature brake lubricant on the pad ears only.
• Do not get grease on the pad friction surface or rotor.

Step 17: Compress the Caliper Piston

• Place an old brake pad against the caliper piston.
• Use the C-clamp 6-inch or brake piston compression tool (specialty) to slowly push the piston fully back into the caliper.
• A piston is the round metal part that pushes the inner pad when you press the brake pedal.
• Watch the brake fluid reservoir under the hood while compressing the piston so it does not overflow.
• Go slowly to protect the brake system.

Step 18: Reinstall the Caliper

• Remove the caliper from the brake caliper hanger hook.
• Slide the caliper over the new pads and rotor.
• Start both guide pin bolts by hand.
• Use the 14mm socket and torque wrench 3/8-inch drive to tighten the caliper guide pin bolts.
• Torque to 22-32 Nm (16-24 ft-lbs).

Step 19: Repeat on the Other Front Side

• Use the same tools and steps on the other front brake assembly.
• Always replace pads and rotors on both front sides together.

Step 20: Reinstall the Wheels

• Install both front wheels by hand.
• Start all lug nuts by hand to prevent cross-threading.
• Use the 21mm lug nut socket and ratchet 1/2-inch drive to snug the lug nuts in a star pattern.

Step 21: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack to lift the vehicle slightly off the jack stands.
• Remove the jack stands.
• Lower the vehicle until the tires touch the ground.
• Use the 21mm lug nut socket and torque wrench 1/2-inch drive to tighten the lug nuts in a star pattern.
• Torque to 88-108 Nm (65-80 ft-lbs).

Step 22: Pump the Brake Pedal

• Before moving your Tucson, press the brake pedal slowly several times until it feels firm.
• This moves the caliper pistons back into position against the new pads.
• If the pedal stays soft or sinks, do not drive the vehicle.

✅ After Repair

• ✅ Check the brake fluid reservoir and top off with DOT 3 brake fluid if needed.
• ✅ Start the engine and press the brake pedal again. It should feel firm.
• ✅ Look behind both front wheels for leaks or loose hardware.
• ✅ Perform a slow test in a safe area before normal driving.
• ✅ Bed in the new pads: make 5-8 moderate stops from about 30 mph to 5 mph, letting the brakes cool briefly between stops.
• ✅ Avoid hard braking for the first 200 miles unless it is an emergency.
• ✅ Recheck lug nut torque after 25-50 miles.
