🔧 Tucson - Rear Brake Pad Replacement

Replacing the rear brake pads on your Tucson means removing the rear wheels, opening the rear brake calipers, swapping the worn pads, and safely compressing the caliper piston so everything fits back together.

This repair restores braking performance and helps prevent damage to the rear brake 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.
• ⚠️ Always support your Tucson with jack stands before removing wheels.
• ⚠️ Wear safety glasses and gloves. Brake dust can irritate skin and eyes.
• ⚠️ Do not press the brake pedal while the caliper is removed.
• ⚠️ Do not let the brake caliper hang by the rubber brake hose.
• ⚠️ Your Tucson uses a mechanical parking brake setup, not an electronic parking brake, so no scan tool retraction is needed.
• ⚠️ Keep the parking brake released during rear brake service.

📋 Before You Begin

• Park your Tucson on level ground and place the transmission in 1st gear.
• Release the parking brake completely before lifting the rear of the vehicle.
• Place wheel chocks in front of both front tires.
• Open the hood and locate the brake fluid reservoir.
• Use a turkey baster or fluid syringe to remove a small amount of brake fluid if the reservoir is near the MAX line.
• A caliper piston is the round part inside the brake caliper that pushes the pads against the rotor.
• A wind-back tool turns and pushes the rear caliper piston inward at the same time.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Rear Lug Nuts

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

Step 2: Lift and Support the Rear

• Use the floor jack at the rear center lifting point or approved rear side pinch weld area.
• Raise the rear of your Tucson high enough for the wheels to clear the ground.
• Place jack stands under the approved rear support points.
• Lower the vehicle gently onto the jack stands.
• Lightly shake the vehicle by hand to confirm it is stable.

Step 3: Remove the Rear Wheels

• Use the 21mm lug nut socket and 1/2-inch drive ratchet to remove the loosened lug nuts.
• Remove both rear wheels and place them flat under the vehicle as an extra safety backup.

Step 4: Inspect the Rear Brake Assembly

• Put on safety glasses and nitrile gloves.
• Look at the caliper, rotor, brake hose, and pad thickness before taking anything apart.
• Use the brake cleaner spray nozzle to rinse loose brake dust away.
• Do not use compressed air on brake dust.

Step 5: Remove the Lower Caliper Bolt

• Use the 14mm socket and 1/2-inch drive ratchet to remove the lower rear caliper slide bolt.
• If the slide pin spins, hold the pin steady with a 17mm wrench while removing the bolt with the 14mm socket.
• A slide pin lets the caliper move smoothly as the brake pads wear.

Step 6: Swing the Caliper Up

• Use your hands to swing the caliper upward away from the brake pads.
• If it sticks, gently use a flat-head screwdriver between the caliper and pad to create a little space.
• Support the caliper with a bungee cord so the brake hose is not stretched.
• Never let it hang by the hose.

Step 7: Remove the Old Brake Pads and Hardware

• Use your hands to slide the old inner and outer pads out of the caliper bracket.
• Use the flat-head screwdriver to gently pry out the old metal pad clips if they do not come out by hand.
• Use the small wire brush to clean the bracket areas where the clips sit.
• Spray the cleaned areas with brake cleaner.

Step 8: Retract the Rear Caliper Piston

• Check the brake fluid reservoir under the hood before pushing the piston in.
• Use the rear brake caliper piston wind-back tool to turn the caliper piston clockwise while pushing inward.
• Turn slowly until the piston is fully seated inside the caliper.
• Watch the brake fluid reservoir so it does not overflow.
• If needed, use the turkey baster or fluid syringe to remove excess fluid.

Step 9: Install the New Hardware and Pads

• Install the new clips from the rear brake hardware kit into the caliper bracket by hand.
• Apply a thin layer of brake caliper slide pin grease to the pad ears where they touch the clips.
• Do not get grease on the pad friction surface or rotor face.
• Slide the new inner and outer rear brake pads into the caliper bracket.
• The pads should move freely in the clips without forcing them.

Step 10: Lower the Caliper and Install the Bolt

• Use your hands to swing the caliper down over the new brake pads.
• If the caliper does not fit, use the rear brake caliper piston wind-back tool again to fully seat the piston.
• Install the lower caliper slide bolt by hand first to avoid cross-threading.
• Use the 14mm socket, 17mm wrench, and torque wrench to tighten the caliper slide bolt.
• Torque to 22-32 Nm (16-24 ft-lbs)

Step 11: Repeat on the Other Side

• Repeat Steps 4 through 10 on the opposite rear brake.
• Rear brake pads must be replaced as a complete axle set.
• Always replace left and right together.

Step 12: Reinstall the Rear Wheels

• Place each rear wheel back onto the hub by hand.
• Install the lug nuts by hand first.
• Use the 21mm lug nut socket and 1/2-inch drive ratchet to snug the lug nuts in a star pattern.

Step 13: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack to raise the rear slightly off the jack stands.
• Remove the jack stands.
• Lower your Tucson fully to the ground.
• Use the 21mm lug nut socket and torque wrench to tighten the lug nuts in a star pattern.
• Torque to 88-107 Nm (65-79 ft-lbs)

Step 14: Pump the Brake Pedal

• Before moving the vehicle, sit in the driver seat and press the brake pedal slowly several times.
• The pedal may go low at first, then become firm.
• This moves the caliper pistons back against the new pads.
• Do not drive until the brake pedal feels firm.

Step 15: Check Brake Fluid Level

• Open the hood and inspect the brake fluid reservoir.
• Add DOT 3 or DOT 4 brake fluid only if the level is below the MIN mark.
• Keep the level between MIN and MAX.
• Reinstall the reservoir cap securely by hand.

✅ After Repair

• ✅ Start your Tucson and press the brake pedal again to confirm it stays firm.
• ✅ Test the brakes at walking speed before driving normally.
• ✅ Listen for scraping, grinding, or clicking noises.
• ✅ Recheck the brake fluid level after the first short drive.
• ✅ Bed in the new pads with several gentle stops from 30 mph to 5 mph.
• ✅ Avoid hard braking for the first 100-200 miles unless needed for safety.
• ✅ Recheck lug nut torque after 25-50 miles using the 21mm lug nut socket and torque wrench.
