⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack alone.
• ⚠️ Support your Tucson with jack stands before putting any part of your body near the wheels or brakes.
• ⚠️ Brake dust can be harmful. Do not blow it with compressed air; use brake cleaner instead.
• ⚠️ Brake parts get very hot after driving. Let the brakes cool before starting.
• ⚠️ The front brakes do not require electronic parking brake service mode on your Tucson.
• ⚠️ Battery disconnect is not required for this front brake job.

📋 Before You Begin

• 🅿️ Park your Tucson on level ground and shift to Park.
• 🧱 Place wheel chocks behind the rear wheels to stop the vehicle from rolling.
• 🛑 Do not set the parking brake if you plan to lift the rear later, but for this front-only brake job it is okay to leave it set before lifting.
• 🔍 Open the hood and check the brake fluid reservoir. If it is very full, remove a small amount with a clean suction tool before compressing the caliper pistons.
• 📘 A caliper is the clamp that squeezes the brake pads against the rotor to stop the vehicle.
• 📘 A rotor is the round metal disc behind the wheel that the brake pads press against.

🔨 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 wheel lug nut about half a turn.
• Do this while the tires are still on 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 at the front center jack point or the proper front side pinch weld lift point.
• Place jack stands under the front pinch weld support points.
• Lower your Tucson gently onto the jack stands.
• Push the vehicle lightly by hand to make sure it is stable before removing the wheels.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket to remove the loosened lug nuts.
• Remove both front wheels and place them flat under the vehicle as an extra safety backup.

Step 4: Remove the Caliper Lower and Upper Slide Bolts

• Turn the steering wheel to give yourself more room on the side you are working on.
• Use the 14mm socket and 3/8-inch drive ratchet to remove the two caliper slide bolts.
• If the slide pin spins, hold it with the 17mm wrench while loosening the bolt with the 14mm socket.
• A slide pin is a smooth pin that lets the caliper move side-to-side as the brakes wear.

Step 5: Lift Off and Support the Caliper

• Use the flat blade screwdriver carefully to wiggle the caliper loose if it feels stuck.
• Lift the caliper off the brake pads and rotor.
• Use the bungee cord to hang the caliper from the strut spring or suspension.
• Do not let the caliper hang by the rubber brake hose.

Step 6: Remove the Old Brake Pads and Hardware

• Pull the old brake pads out of the caliper bracket by hand.
• Use the flat blade screwdriver to carefully pry out the old stainless pad clips.
• The pad clips are thin metal guides that help the pads slide smoothly.
• Use the wire brush to clean the bracket areas where the clips sit.

Step 7: Remove the Caliper Bracket

• Use the 17mm socket, 3/8-inch drive ratchet, or 1/2-inch drive breaker bar to remove the two caliper bracket bolts.
• Hold the bracket with one hand as the last bolt comes out.
• Set the bracket on a clean surface.

Step 8: 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. An impact screwdriver turns when struck and helps remove tight screws without stripping them.
• Press hard to avoid stripping screws.

Step 9: Remove the Old Rotor

• Pull the rotor straight off the wheel hub by hand.
• If it is stuck from rust, tap the rotor hat area with a suitable hammer if available, avoiding the wheel studs.
• Use the wire brush to clean rust from the hub face.
• Spray the hub face with brake cleaner spray and wipe it with shop towels.
• The hub face must be clean so the new rotor sits flat and does not cause vibration.

Step 10: Install the New Rotor

• Spray both sides of the new rotor with brake cleaner spray and wipe it dry with shop towels.
• Slide the new rotor onto the hub.
• Reinstall the rotor retaining screws with the Phillips #3 screwdriver.
• Tighten the rotor screws snugly by hand. Do not over-tighten them.

Step 11: Service the Caliper Bracket and Slide Pins

• Use the wire brush to clean the caliper bracket where the new hardware clips install.
• Install the new brake hardware clips by hand.
• Pull the slide pins out of the bracket by hand and wipe them with shop towels.
• Apply a light coat of disc brake caliper slide pin grease to the slide pins.
• Push the slide pins back into the bracket until they move smoothly.
• Use brake grease only on slide pins.

Step 12: Reinstall the Caliper Bracket

• Place the caliper bracket over the new rotor.
• Start both caliper bracket bolts by hand to avoid cross-threading.
• Use the 17mm socket and 1/2-inch drive torque wrench to tighten the caliper bracket bolts.
• Torque to 88-98 Nm (65-72 ft-lbs).

Step 13: Install the New Brake Pads

• Slide the new brake pads into the new hardware clips by hand.
• Make sure the friction material faces the rotor.
• Apply a very thin layer of disc brake caliper slide pin grease only to pad ears where they touch the clips.
• Do not get grease on the rotor or pad friction surface.

Step 14: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use the C-clamp brake caliper compression tool to slowly push the piston fully back into the caliper.
• Compress slowly and check the brake fluid reservoir so it does not overflow.
• The piston is the round part inside the caliper that pushes the brake pad.

Step 15: Reinstall the Caliper

• Remove the bungee cord and place the caliper over the new pads.
• Start both slide bolts by hand.
• Use the 14mm socket and 3/8-inch drive ratchet to snug the slide bolts.
• If the slide pin spins, hold it with the 17mm wrench.
• Use the 14mm socket and 1/2-inch drive torque wrench to tighten the slide bolts.
• Torque to 22-32 Nm (16-24 ft-lbs).

Step 16: Repeat on the Other Front Side

• Use the same tools and repeat Steps 4 through 15 on the other front brake.
• Always replace front brake pads and rotors in pairs.

Step 17: Reinstall the Wheels

• Place each wheel back onto the hub.
• Start all lug nuts by hand.
• Use the 21mm lug nut socket to snug the lug nuts in a star pattern.

Step 18: Lower and Torque the Lug Nuts

• Use the floor jack to lift your Tucson slightly off the jack stands.
• Remove the jack stands and lower the vehicle to the ground.
• Use the 21mm lug nut socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Torque to 88-107 Nm (65-79 ft-lbs).

Step 19: Pump the Brake Pedal

• Before driving, 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.
• If you skip this step, the brake pedal may go low on the first press.

✅ After Repair

• ✅ Check the brake fluid level and top off only if needed with the correct brake fluid listed on the reservoir cap.
• ✅ Start your Tucson and press the brake pedal again. It should feel firm and normal.
• ✅ Check behind both front wheels for leaks or loose parts.
• ✅ Test drive slowly in a safe area before normal driving.
• ✅ Bed in the brakes by making several gentle stops from about 30 mph, allowing time between stops for cooling.
• ✅ Avoid hard braking for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after 25-50 miles.
