This job replaces the front brake pads on your Tucson. Brake pads wear down over time and should be replaced before they damage the rotors or reduce stopping power.

Difficulty Level: Beginner | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface and never rely on a jack alone.
• ⚠️ Always support your Tucson with jack stands before working near the wheels.
• ⚠️ Brake dust is harmful. Do not blow it off with compressed air; use brake cleaner.
• ⚠️ Brake fluid can damage paint. Wipe spills immediately with a clean rag.
• ⚠️ After installation, the brake pedal will feel soft until you pump it several times.
• ⚠️ Battery disconnect is not required for this front brake pad replacement.

📋 Before You Begin

• Park your Tucson on level ground.
• Shift the transmission to Park.
• Set the parking brake.
• Place wheel chocks behind the rear wheels.
• Open the hood and locate the brake fluid reservoir.
• Do not remove fluid unless the reservoir is already at or above the MAX line.
• A brake pad spreader tool pushes the caliper piston back into its bore so the new, thicker pads fit.
• A torque wrench tightens bolts to a measured amount so they are not too loose or over-tightened.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use a 21mm lug nut socket and 1/2-inch breaker bar to loosen each front 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 lug nuts yet.

Step 2: Raise and Support the Front

• Use a floor jack to lift the front of your Tucson at the front center jacking point.
• Place jack stands under the front side pinch welds or front support points.
• Slowly lower the Tucson onto the jack stands.
• Gently shake the vehicle by hand to confirm it is stable before working.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket and ratchet to remove the loosened lug nuts.
• Remove both front wheels.
• Slide one wheel under the side of the vehicle as an extra safety backup.

Step 4: Inspect the Brake Assembly

• Put on safety glasses and nitrile gloves.
• Use brake cleaner spray over a catch pan to wet down brake dust.
• Look at the brake hose and caliper for leaks, cracks, or damage.
• If the rotor is deeply grooved, cracked, or badly rusted, replace or resurface the rotor before installing new pads.

Step 5: Remove the Lower Caliper Bolt

• Use a 14mm socket and 3/8-inch ratchet to remove the lower caliper guide pin bolt.
• If the guide pin spins, hold the pin with a 17mm wrench while removing the bolt with the 14mm socket.
• The caliper is the clamp-shaped part that squeezes the brake pads against the rotor.

Step 6: Swing the Caliper Up

• Use a flat-blade screwdriver gently between the caliper and outer pad to create slight clearance.
• Swing the caliper upward by hand.
• Use a bungee cord to support the caliper from the strut spring.
• Do not let the caliper hang by the rubber brake hose.

Step 7: Remove the Old Brake Pads

• Slide the old inner and outer pads out of the caliper bracket by hand.
• Use a flat-blade screwdriver only if a pad is stuck.
• Note the position of any wear indicator tab before removal.
• The wear indicator is a small metal tab that squeals when pads get too thin.

Step 8: Replace the Pad Hardware

• Use a flat-blade screwdriver to remove the old metal pad clips from the caliper bracket.
• Use a wire brush to clean the bracket areas where the clips sit.
• Spray the area with brake cleaner spray over the catch pan.
• Install the new front brake pad hardware kit clips by hand until fully seated.
• Clean clips help prevent brake noise.

Step 9: Compress the Caliper Piston

• Check the brake fluid reservoir under the hood before compressing the piston.
• If the fluid is near the MAX line, remove a small amount with a clean suitable suction tool before continuing.
• Place an old brake pad against the caliper piston.
• Use a disc brake pad spreader tool or 6-inch C-clamp to slowly push the piston fully back into the caliper.
• Go slowly so brake fluid does not overflow from the reservoir.

Step 10: Lubricate the New Pads

• Apply a thin layer of brake lubricant to the pad backing plates where they contact the caliper and bracket.
• Apply a small amount of brake lubricant to the pad ears where they slide in the clips.
• Do not put lubricant on the friction material or rotor face.
• The friction material is the rough surface that touches the rotor.

Step 11: Install the New Brake Pads

• Slide the new inner and outer pads into the caliper bracket by hand.
• Make sure each pad moves smoothly in the new hardware clips.
• If a pad binds, remove it and clean the bracket again with the wire brush.
• Install pads as an axle set; always replace both front sides together.

Step 12: Reinstall the Caliper

• Remove the bungee cord and swing the caliper down over the new pads.
• Use a 14mm socket and 3/8-inch ratchet to install the lower caliper guide pin bolt.
• If the guide pin spins, hold it with a 17mm wrench.
• Use a 3/8-inch torque wrench and 14mm socket to tighten the caliper guide pin bolt.
• Torque to 22-32 Nm (16-24 ft-lbs)

Step 13: Repeat on the Other Front Side

• Use the same 14mm socket, 17mm wrench, brake pad spreader tool, and brake lubricant to replace the pads on the other front wheel.
• Always complete both front sides before driving.

Step 14: Reinstall the Wheels

• Place each front wheel back on the hub.
• Thread the lug nuts by hand first to avoid cross-threading.
• Use the 21mm lug nut socket and ratchet to snug the lug nuts in a star pattern.

Step 15: Lower and Torque the Wheels

• Use the floor jack to raise the vehicle slightly and remove the jack stands.
• Lower your Tucson until the tires touch the ground.
• Use a 1/2-inch torque wrench and 21mm lug nut socket to tighten the lug nuts in a star pattern.
• Torque to 88-107 Nm (65-79 ft-lbs)

Step 16: Pump the Brake Pedal

• Sit in the driver seat and press the brake pedal slowly several times.
• Keep pumping until the pedal feels firm.
• Do not drive until the pedal is firm.

✅ After Repair

• ✅ Check the brake fluid level and set it between MIN and MAX if needed.
• ✅ Start the engine and press the brake pedal again to confirm it feels firm.
• ✅ Look behind both front wheels for leaks or anything loose.
• ✅ Test drive slowly in a safe area and make several gentle stops.
• ✅ Avoid hard braking for the first 200 miles unless it is an emergency.
• ✅ Recheck lug nut torque after your first short drive.
