This repair replaces the front brake pads on your Tucson. The front pads wear down over time and should be replaced before the friction material gets too thin or starts damaging the rotors.

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

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack by itself.
• ⚠️ Use jack stands before putting any part of your body near the wheel well.
• ⚠️ Brake dust can be harmful. Do not blow it with compressed air; use brake cleaner.
• ⚠️ Brake parts may be hot if the vehicle was recently driven. Let them cool first.
• ⚠️ Brake fluid can damage paint. Wipe spills immediately with a clean shop towel.
• ⚠️ Battery disconnect is not required for this front brake pad replacement.

📋 Before You Begin

• 🅿️ Park your Tucson on level ground and shift to Park.
• 🧱 Place wheel chocks behind the rear wheels so the vehicle cannot roll.
• 🔒 Set the parking brake. The front brakes do not require electronic parking brake service mode.
• 🧪 Open the hood and locate the brake fluid reservoir. If it is filled to the top, remove a small amount with a clean towel or suction tool before compressing the caliper piston.
• 🛠️ A brake caliper compression tool pushes the caliper piston back into its bore so the thicker new pads will fit.
• 🛞 Slightly loosen the front lug nuts before lifting the vehicle.

🔨 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 drive breaker bar to loosen each front lug nut about half a turn.
• Do not remove the lug nuts yet.
• Loosen before lifting.

Step 2: Raise and Support the Front

• Use the floor jack to lift the front of your Tucson at the proper front jacking point.
• Place jack stands under the front side pinch weld support points.
• Slowly lower the vehicle 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 3/8-inch drive ratchet to remove the loosened 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 and nitrile gloves.
• Use brake cleaner spray to wet down brake dust around the caliper and pads.
• Use a shop towel to wipe away loose dirt.
• Look at the rotor surface. If it is deeply grooved, cracked, or heavily rust-pitted, the rotors should be replaced or resurfaced.

Step 5: Remove the Lower Caliper Slide Bolt

• Use the 17mm wrench to hold the slide pin if it tries to spin.
• Use the 14mm socket and 3/8-inch drive ratchet to remove the lower caliper slide bolt.
• A slide pin is the small smooth pin the caliper moves on as the pads wear.

Step 6: Swing the Caliper Up

• Use the flat blade screwdriver gently between the old pad and rotor to create a small amount of clearance.
• Swing the caliper upward by hand.
• Do not let the caliper hang by the rubber brake hose.
• If needed, rest the caliper carefully on the knuckle area so the hose is not stretched.

Step 7: Remove the Old Brake Pads

• Pull the inner and outer brake pads out of the caliper bracket by hand.
• Use the flat blade screwdriver only if a pad is stuck.
• Note the position of any wear indicator tab so the new pads go in the same orientation.

Step 8: Remove and Clean the Pad Hardware

• Use the flat blade screwdriver to lift the old stainless pad clips out of the caliper bracket.
• Use the wire brush to clean rust and dirt from the bracket where the clips sit.
• Spray the area with brake cleaner spray and wipe it with a shop towel.
• Pad clips are thin metal guides that let the brake pads slide smoothly.

Step 9: Install the New Hardware

• Press the new front brake pad hardware kit clips into the caliper bracket by hand.
• Apply a light coat of synthetic brake lubricant to the pad contact points on the clips.
• Do not get lubricant on the rotor or pad friction material.
• Grease metal contact points only.

Step 10: Compress the Caliper Piston

• Check the brake fluid reservoir under the hood before compressing the piston.
• Use the brake caliper compression tool with one old brake pad against the piston face.
• Slowly press the piston fully back into the caliper.
• Watch the brake fluid level while compressing. Use a shop towel to catch any overflow.
• The piston is the round part inside the caliper that pushes the brake pad against the rotor.

Step 11: Install the New Brake Pads

• Slide the new inner and outer front brake pads into the caliper bracket by hand.
• Make sure the pads move freely in the new clips.
• If the pads are tight, remove them and clean the bracket again with the wire brush.

Step 12: Reinstall the Caliper

• Swing the caliper down over the new pads by hand.
• Use the 14mm socket and 3/8-inch drive ratchet to install the lower caliper slide bolt.
• Use the 17mm wrench to hold the slide pin if it spins.
• Tighten the caliper slide bolt to Torque to 26 Nm (19 ft-lbs).

Step 13: Repeat on the Other Front Side

• Use the same tools and steps to replace the brake pads on the other front wheel.
• Always replace front brake pads in pairs so braking stays even.

Step 14: Reinstall the Wheels

• Place each front wheel back onto the hub by hand.
• Start all lug nuts by hand to avoid cross-threading.
• Use the 21mm lug nut socket and 3/8-inch drive ratchet to snug the lug nuts in a star pattern.

Step 15: 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 your Tucson fully to the ground with the floor jack.
• Use the 21mm lug nut socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Tighten the wheel lug nuts to Torque to 108 Nm (80 ft-lbs).

Step 16: Pump the Brake Pedal

• Sit in the driver seat and press the brake pedal several times until it feels firm.
• This moves the caliper pistons back against the new pads.
• Do not drive until the pedal feels firm.

✅ After Repair

• ✅ Check the brake fluid reservoir and top off with DOT 4 brake fluid only if the level is below the MIN mark.
• ✅ Start your Tucson and press the brake pedal again. It should feel firm, not sink to the floor.
• ✅ Test the brakes at very low speed in a safe area before normal driving.
• ✅ Avoid hard braking for the first 200 miles unless needed for safety.
• ✅ For bedding-in, make several gentle stops from about 30 mph to help the pads seat evenly.
• ✅ Recheck lug nut torque after 25-50 miles with the 1/2-inch drive torque wrench.
