🔧 Tucson - Front Brake Pads & Rotor Replacement

You’ll remove the front calipers, swap the brake pads, and replace the rotors on your Tucson. This restores braking power, reduces vibration/pulsation, and prevents uneven pad wear.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Support the Tucson with jack stands; never rely on a floor jack alone.
• ⚠️ Brakes may contain dust—avoid blowing it out; use brake cleaner instead.
• ⚠️ Do not let the caliper hang by the brake hose; support it with a hanger.
• ⚠️ Watch the brake fluid level when compressing pistons; siphon a little if it may overflow.
• ⚠️ After reassembly, pump the brake pedal until firm before driving.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Loosen the front wheel lug nuts 1/2 turn with a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir. Do not remove it yet, just note the current level.
• C-clamp note: A C-clamp slowly pushes the piston back in.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of the Tucson

• Lift the front with a floor jack (rated 3-ton minimum) at the front jacking point.
• Set the vehicle onto jack stands (rated 3-ton minimum) placed at the front pinch welds/subframe points.
• Remove the wheels using a 21mm socket.

Step 2: Inspect and prepare the caliper

• Turn the steering wheel to give yourself more room (left side: turn wheel right; right side: turn wheel left).
• Look at the brake hose routing and ABS wire so you don’t pull/stretch them.
• Use brake cleaner and safety glasses to clean loose dust.

Step 3: Remove the caliper (keep the hose safe)

• Remove the two caliper slide pin bolts using a 14mm socket and 3/8" drive ratchet.
• Carefully lift the caliper off the bracket. Use a flathead screwdriver gently if it’s tight.
• Hang the caliper with a brake caliper hanger hook so the hose is not supporting weight.

Step 4: Remove the old pads and hardware

• Slide the pads out of the bracket by hand.
• Remove the pad abutment clips (hardware) with a flathead screwdriver.
• Clean the bracket pad “rails” (where clips sit) using a wire brush and brake cleaner.

Step 5: Remove the caliper bracket

• Remove the two bracket-to-knuckle bolts using a 17mm socket and breaker bar.
• Set the bracket aside on a clean surface.
• During reassembly: Torque to 98-108 Nm (72-80 ft-lbs).

Step 6: Remove the rotor

• If your rotor has retaining screws, remove them with a Phillips #3 screwdriver. If stuck/stripping, use an impact driver (specialty).
• Pull the rotor off the hub. If it’s rust-stuck, tap the rotor “hat” area with a rubber mallet to break it free.
• Clean the hub face with a wire brush and wipe with shop towels. This helps prevent pedal pulsation.

Step 7: Install the new rotor

• Spray both sides of the new rotor with brake cleaner and wipe with shop towels (removes protective oil).
• Place the rotor on the hub. Reinstall the retaining screw(s) with a Phillips #3 screwdriver if equipped (snug only).

Step 8: Reinstall the bracket with new hardware clips

• Reinstall the caliper bracket using a 17mm socket.
• Torque to 98-108 Nm (72-80 ft-lbs) using a torque wrench (20-150 ft-lbs).
• Install the new abutment clips from the hardware kit by hand; seat them fully.

Step 9: Service the slide pins

• Pull the slide pins out of the bracket by hand.
• Wipe old grease off with shop towels.
• Apply a thin coat of brake caliper slide pin grease (silicone) and reinstall the pins so they move smoothly.
• Tip: Pins must slide easily by hand.

Step 10: Compress the caliper piston

• Check the brake fluid reservoir under the hood; if it’s near MAX, remove a little using shop towels to catch spills.
• Place an old pad against the piston face, then use a C-clamp (6" minimum) to slowly press the piston back into the caliper.
• Go slowly and keep the piston straight.

Step 11: Install new pads and reinstall the caliper

• Install the new pads into the bracket by hand (they should slide freely in the clips).
• Lower the caliper over the new pads.
• Install the two slide pin bolts using a 14mm socket.
• Torque to 28-32 Nm (21-24 ft-lbs) using a torque wrench (20-150 ft-lbs).

Step 12: Reinstall wheels and torque lug nuts

• Put the wheels back on and hand-thread the lug nuts.
• Lower the Tucson to the ground using a floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a 21mm socket and torque wrench (20-150 ft-lbs).
• Torque to 88-107 Nm (65-79 ft-lbs).

✅ After Repair

• With the engine OFF, press the brake pedal 10-15 times until it feels firm.
• Check the brake fluid level and top off with DOT 3 brake fluid if needed.
• Start the engine and confirm the pedal feels normal (it will drop slightly with brake booster assist).
• Do a cautious test drive and verify no pulling, grinding, or warning lights.
• Brake pad bedding (recommended): make 6-10 moderate stops from 35 mph to 5 mph, then drive to cool for 10 minutes.
