⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack alone.
• ⚠️ Always support your Tucson with jack stands before removing wheels.
• ⚠️ Brake dust can be harmful. Do not blow it with compressed air.
• ⚠️ Brake cleaner is flammable. Keep it away from sparks, flames, and hot parts.
• ⚠️ The front brake caliper must be supported. Do not let it hang by the rubber brake hose.
• ⚠️ Battery disconnect is not required for front brake pad and rotor replacement.

🔨 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 1/2 turn.
• Do not remove the lug nuts yet.
• Loosen while tires touch ground.

Step 2: Lift and Support the Front

• Use a floor jack rated 2-ton minimum at the front center jacking point or approved side pinch weld lift point.
• Place jack stands rated 2-ton minimum under the approved front support points.
• Lower your Tucson gently onto the jack stands.
• Lightly shake the vehicle by hand to make sure it is stable.

Step 3: Remove the Front Wheels

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

Step 4: Remove the Brake Caliper

• Turn the steering wheel to give yourself more room on the side you are working on.
• Use a 14mm socket and 3/8-inch ratchet to remove the two caliper slide pin bolts.
• Lift the caliper off the brake pads.
• Use a bungee cord 24-inch to hang the caliper from the strut spring.
• Do not let the caliper hang by the brake hose.
• During installation, tighten the caliper slide pin bolts to Torque to 22-26 Nm (16-19 ft-lbs).

Step 5: Remove the Old Brake Pads and Hardware

• Pull the old brake pads out of the caliper bracket by hand.
• Use a flat edge of a wire brush to clean the pad contact areas on the bracket.
• Remove the old stainless pad clips by hand or with the edge of the Phillips #3 screwdriver.
• A brake hardware kit includes small metal clips that help the pads slide smoothly.

Step 6: Remove the Caliper Bracket

• Use a 17mm socket and 1/2-inch breaker bar to remove the two caliper bracket bolts.
• Remove the caliper bracket from the steering knuckle.
• During installation, tighten the caliper bracket bolts to Torque to 98-108 Nm (72-80 ft-lbs).

Step 7: Remove the Old Rotor

• Use a Phillips #3 screwdriver to remove the rotor retaining screw.
• If the screw is stuck, use an impact screwdriver. An impact screwdriver turns when struck and helps loosen stuck screws.
• Pull the rotor straight off the hub.
• If the rotor is stuck from rust, tap the rotor hat area with a hammer if available, but do not hit the wheel studs.
• During installation, tighten the rotor retaining screw snugly to Torque to 4-7 Nm (35-62 in-lbs).

Step 8: Clean the Hub Face

• Use a wire brush to clean rust from the wheel hub face.
• Wipe the hub with shop towels.
• Apply a very thin film of anti-seize compound to the hub face only.
• Do not get anti-seize on the wheel studs, brake pads, or rotor friction surface.
• Thin coating only prevents rotor sticking.

Step 9: Install the New Rotor

• Clean both sides of the new rotor with brake cleaner aerosol and wipe dry with shop towels.
• Slide the new rotor onto the hub.
• Install the rotor retaining screw with the Phillips #3 screwdriver.
• Tighten the screw to Torque to 4-7 Nm (35-62 in-lbs).

Step 10: Service the Caliper Bracket

• Use the wire brush to clean the caliper bracket where the new clips sit.
• Install the new brake pad hardware clips by hand.
• Apply a light layer of silicone-based brake lubricant on the clip contact points only.
• Do not put grease on the pad friction material or rotor surface.

Step 11: Reinstall the Caliper Bracket

• Place the caliper bracket over the rotor.
• Thread both bracket bolts by hand first to avoid cross-threading.
• Use a 17mm socket and torque wrench 10-150 ft-lb to tighten the bolts.
• Tighten to Torque to 98-108 Nm (72-80 ft-lbs).

Step 12: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use a C-clamp 6-inch or brake caliper piston compressor to slowly push the piston fully back into the caliper.
• Watch the brake fluid reservoir while compressing the piston. Remove excess fluid if it gets close to overflowing.
• Go slowly to avoid damaging the brake hydraulic system.

Step 13: Install the New Brake Pads

• Install the new inner and outer pads into the caliper bracket by hand.
• Make sure the pad ears sit fully in the new hardware clips.
• Apply a small amount of silicone-based brake lubricant to the pad ears only.
• Do not grease the pad friction surface.

Step 14: Reinstall the Caliper

• Lower the caliper over the new brake pads.
• Thread the two caliper slide pin bolts by hand.
• Use a 14mm socket and torque wrench 10-150 ft-lb to tighten the bolts.
• Tighten to Torque to 22-26 Nm (16-19 ft-lbs).

Step 15: Repeat on the Other Side

• Repeat Steps 4 through 14 on the opposite front brake.
• Always replace front brake pads and rotors in pairs.
• Both sides must match.

Step 16: Reinstall the Wheels

• Place each front wheel back onto the hub.
• Thread the lug nuts by hand.
• Use the 21mm lug nut socket to snug the lug nuts in a star pattern.
• Do not fully torque the lug nuts while the vehicle is still raised.

Step 17: Lower and Torque the Wheels

• Use the floor jack rated 2-ton minimum to lift your Tucson slightly off the jack stands.
• Remove the jack stands rated 2-ton minimum.
• Lower the vehicle until the tires touch the ground.
• Use a 21mm lug nut socket and torque wrench 10-150 ft-lb to tighten the lug nuts in a star pattern.
• Tighten lug nuts to Torque to 107-127 Nm (79-94 ft-lbs).

Step 18: Pump the Brake Pedal

• Sit in the driver seat and press the brake pedal slowly 5-8 times.
• The pedal will feel soft at first, then become firm.
• Do not drive until the brake pedal feels firm.

✅ After Repair

• ✅ Check the brake fluid level and top off with DOT 4 brake fluid if needed.
• ✅ Start your Tucson and press the brake pedal again. Confirm it feels firm.
• ✅ Look behind both front wheels for brake fluid leaks.
• ✅ Test drive slowly in a safe area before normal driving.
• ✅ Bed in the new pads: make 8-10 moderate stops from about 35 mph to 10 mph, allowing 30-60 seconds between stops.
• ✅ Avoid hard braking for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after 25-50 miles: Torque to 107-127 Nm (79-94 ft-lbs).
