🔧 Tucson - Front Brake Pads & Rotors Replacement

You’ll remove the front wheels, unbolt the brake calipers, replace the pads and rotors, then reassemble and torque everything correctly. This restores braking power and prevents vibration/pulsation from worn or warped rotors.

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

⚠️ Safety & Precautions

• Work on level ground and support your Tucson with jack stands—never rely on a jack alone.
• Brake parts may contain dust—avoid blowing with compressed air; use brake cleaner.
• Do not let the brake caliper hang by the hose—support it with a bungee cord.
• Keep grease off pad/rotor friction surfaces. If you touch them, clean with brake cleaner.
• No battery disconnect is required for front brake pads/rotors.

📋 Before You Begin

• Park on level ground, shift to P, and set the parking brake.
• Chock the rear wheels with wheel chocks.
• Crack the front lug nuts loose 1/2 turn using a 21mm lug nut socket and breaker bar before lifting.
• Open the hood and remove the brake fluid reservoir cap (set it loosely on top). This helps when compressing caliper pistons.
• Take a quick photo of each side before disassembly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and support the front

• Use a floor jack (rated 3-ton minimum) to lift the front of your Tucson at the proper front jacking point.
• Place jack stands (rated 3-ton minimum) under the front support points and lower onto the stands.
• Remove the wheels using a 21mm lug nut socket and ratchet (1/2").

Step 2: Remove the brake caliper (the clamp that squeezes the pads)

• Turn the steering wheel to give yourself more room (left for right side work, right for left side work).
• Use a 14mm socket and ratchet (3/8") to remove the two caliper slide pin bolts.
• Carefully lift the caliper off the bracket and hang it from the strut spring with a bungee cord.
• Do not twist or stretch the brake hose.

Step 3: Remove pads and the caliper bracket (the metal carrier that holds the pads)

• Slide the old brake pads out of the bracket by hand. If stuck, gently pry with a small flat screwdriver.
• Use a 17mm socket and breaker bar (1/2") to remove the two caliper bracket bolts.
• Remove the caliper bracket and set it aside.
• When reinstalling later: Torque to 98-118 Nm (72-87 ft-lbs) on the caliper bracket bolts.

Step 4: Remove the rotor

• Pull the rotor straight off the hub.
• If it’s rust-stuck, tap the rotor hat with a rubber mallet to break it loose, then remove it.
• Clean the hub face with a wire brush and wipe with shop towels.

Step 5: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray and wipe with shop towels to remove packing oil.
• Place the new rotor onto the hub.
• To hold it square while you work, thread on one lug nut by hand (use your 21mm lug nut socket only to snug lightly).

Step 6: Service the bracket hardware and slide pins

• Remove the old pad clips from the bracket using a small flat screwdriver.
• Clean the bracket pad “rails” (where the clips sit) with a wire brush.
• Install the new hardware clips (from the hardware kit) by hand.
• Pull the slide pins out one at a time, wipe clean with shop towels, apply a thin coat of brake caliper grease (silicone-based), then reinstall.
• Only grease metal-to-metal sliding points.

Step 7: Reinstall the caliper bracket

• Apply medium-strength threadlocker (blue) to the caliper bracket bolt threads.
• Install the bracket bolts using a 17mm socket and ratchet (1/2").
• Torque to 98-118 Nm (72-87 ft-lbs) using a torque wrench (ft-lb range).

Step 8: Compress the caliper piston

• Place one old brake pad against the piston face.
• Use a C-clamp (6") to slowly press the piston back into the caliper until fully seated.
• Watch the brake fluid reservoir while compressing—if it starts to overflow, stop and remove some fluid (use shop towels to prevent paint damage).

Step 9: Install new pads and reinstall the caliper

• Install the new pads into the bracket (inner pad on the inside, outer pad on the outside).
• Lower the caliper over the new pads.
• Install the caliper slide pin bolts using a 14mm socket and ratchet (3/8").
• Torque to 22-32 Nm (16-24 ft-lbs) using a torque wrench (ft-lb range).

Step 10: Reinstall wheels and torque lug nuts

• Reinstall the wheels by hand-starting all lug nuts.
• Lower the vehicle off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a 21mm lug nut socket and torque wrench (ft-lb range).
• Torque to 90-110 Nm (66-81 ft-lbs).

Step 11: Repeat on the other front wheel

• Repeat Steps 2–10 on the opposite side.
• Always replace pads/rotors on both sides.

✅ After Repair

• Before starting your Tucson, pump the brake pedal 10–15 times until it feels firm. This seats the pads against the rotors.
• Check the brake fluid level and install the reservoir cap.
• Test at low speed first: confirm normal stopping and no pulling/noises.
• Basic pad bedding (break-in): make 6–10 moderate stops from ~35 mph down to ~5 mph, with 30–60 seconds between stops to cool.
• Recheck lug nut torque after a short drive (use your torque wrench (ft-lb range)).
