Complete replacement of front brake pads and rotors on a 2016-2024 Hyundai Tucson 2.5L I4 AWD, including caliper service and proper torque specifications.

Warnings

Tools required

Parts

• Front brake pad set (4 pads total) × 1 — Use OEM or quality aftermarket equivalent
• Front brake rotors × 2 — Use OEM specification
• Brake hardware/anti-rattle clips kit × 1 — Often included with pad set

Fluids

• DOT 4 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid surface and engage parking brake firmly.
2. Place wheel chocks behind rear wheels to prevent rolling.
3. Open hood and locate brake fluid reservoir. Check fluid level and remove approximately 2-3 ounces with turkey baster to prevent overflow when compressing pistons.
4. Loosen front wheel lug nuts approximately one turn while vehicle is on ground.
5. Lift front of vehicle with floor jack at designated front jacking point and support securely on jack stands at manufacturer-specified support points.
6. Remove both front wheels completely and set aside.

Procedure

1. 1

   Inspect brake system and remove caliper slide pin bolts
   Visually inspect brake lines, hoses, and caliper for leaks or damage. Note condition of slide pins for proper lubrication. Using a 17mm socket, remove the two caliper slide pin bolts (upper and lower) that secure the caliper to the bracket. These are located on the rear of the caliper assembly.

2. 2

   Remove caliper and secure
   Carefully lift the caliper assembly off the rotor and brake pads. Do NOT allow caliper to hang by the brake hose. Use wire or bungee cord to suspend the caliper from the suspension spring or strut - ensure there is no tension on the brake line. The caliper should hang freely without stress on the hose.
   ⚠️Allowing caliper to hang by brake hose can damage hose internally, potentially causing brake failure.
3. 3

   Remove old brake pads and hardware
   Remove the old brake pads from the caliper bracket. Note orientation of inner and outer pads (they may be different). Remove any anti-rattle clips, springs, or shims from the bracket. Inspect these components - if worn or damaged, replace with new hardware kit. Clean the pad contact areas on the bracket with a wire brush.
4. 4

   Remove caliper bracket
   Using an 18mm socket, remove the two caliper bracket bolts that secure the bracket to the steering knuckle. These bolts are very tight and may require a breaker bar. Once removed, lift the caliper bracket off the rotor. Inspect bracket for wear, scoring, or damage.

5. 5

   Remove old rotor
   Pull the old rotor straight off the wheel hub. If rotor is stuck due to corrosion, use a rubber mallet to tap around the rotor hat (center section) and edges - do NOT hit the rotor friction surface. Some Tucson models have small threaded holes in the rotor face where M8 bolts can be threaded to push the rotor off. Clean the hub surface with a wire brush to remove rust and debris.
6. 6

   Prepare and install new rotor
   Clean new rotor thoroughly with brake cleaner to remove protective oil coating - spray both sides and wipe with clean shop towels. Clean the wheel hub mating surface. Slide new rotor onto hub, ensuring it sits flat. If rotor has directional marking or 'outboard' designation, ensure proper orientation. Temporarily secure with one lug nut if needed to prevent rotation during reassembly.
7. 7

   Reinstall caliper bracket with thread locker
   Apply medium-strength thread locker to the threads of both caliper bracket bolts. Position the bracket over the rotor and align with mounting holes on the steering knuckle. Thread both bolts by hand first to ensure proper alignment, then torque to specification using a star pattern (alternate between bolts). Verify bracket is secure and does not move.
   ⚠Thread locker is required on bracket bolts to prevent loosening during operation.

8. 8

   Install new brake hardware and pads
   Install new anti-rattle clips and hardware into the caliper bracket according to kit instructions. Apply a thin layer of silicone brake grease to the backing plates of the new pads (where they contact the clips) - do NOT get grease on friction material. Install the new brake pads into the bracket, ensuring correct orientation (inner and outer pads may differ). Verify pads move freely in the bracket.
9. 9

   Compress caliper piston
   Using a C-clamp or brake piston compression tool, slowly compress the caliper piston fully into its bore. Position the tool against the back of the piston and the rear of the caliper housing. Compress slowly to allow fluid to return to the reservoir. Ensure piston compresses evenly and does not cock to one side. Check brake fluid reservoir - it should rise but not overflow.
   ⚠If piston does not compress smoothly or is seized, caliper may need replacement. Do not force.
10. 10

    Service and reinstall caliper slide pins
    Remove both slide pins from the caliper bracket. Inspect pins for wear, corrosion, or damage. Wipe clean and inspect rubber boots for tears. Apply fresh silicone brake grease generously to the smooth portion of each slide pin. Reinstall pins into their boots and brackets. Position caliper over the new brake pads and align slide pin bolts.
11. 11

    Install caliper and torque slide pin bolts
    Apply silicone brake grease to the threads of the caliper slide pin bolts as specified. Thread both slide pin bolts by hand through the caliper into the slide pins. Torque both bolts to specification. Verify caliper moves freely on slide pins when pressed - this ensures proper brake operation.
    ⚠Caliper must move freely on slide pins. Seized pins cause uneven pad wear and reduced braking.

12. 12

    Repeat procedure on opposite side
    Perform steps 1-11 on the opposite front wheel to replace the second rotor and brake pad set. Ensure all torque specifications and procedures are followed identically on both sides for balanced braking performance.
13. 13

    Reinstall wheels and initial torque
    Clean wheel mounting surfaces on hub. Install wheels onto hubs, ensuring they seat properly. Thread all lug nuts by hand to prevent cross-threading. Tighten lug nuts in a star pattern with a wrench, but do not fully torque yet. Lower vehicle to ground so weight is on wheels.
14. 14

    Final torque wheel lug nuts
    With vehicle weight on wheels, torque all lug nuts to specification using a star pattern (across the wheel, not around in sequence). This ensures even seating and pressure distribution. After torquing all lugs, make one final pass to verify torque.

    Restore brake pedal and check fluid
    Before moving vehicle, pump brake pedal slowly and firmly 15-20 times until pedal feels firm and travels less than halfway to floor. This repositions caliper pistons against new pads. Check brake fluid reservoir and top off to MAX line with fresh DOT 4 fluid if needed. Wipe any spills immediately. Ensure reservoir cap is secure.
    ⚠️DO NOT attempt to drive vehicle until brake pedal is firm. Pumping pedal is essential to restore brake function.

Reassembly

1. Verify all tools and parts have been removed from under vehicle and engine bay.
2. Double-check that all caliper bolts are torqued to specification - loose bolts can cause catastrophic brake failure.
3. Check brake fluid level is between MIN and MAX marks - top off if needed with DOT 4 only.
4. Ensure no brake fluid has spilled on rotors or pads - clean with brake cleaner if necessary.

Verification

• With vehicle still parked, press brake pedal firmly - it should feel solid and not sink to floor. If pedal is soft or spongy, bleed brake system.
• Start engine and press brake pedal - pedal should remain firm with no significant drop in height.
• Perform a low-speed test drive in a safe area (empty parking lot). Test brakes at 5-10 mph multiple times to verify proper operation.
• Listen for any unusual noises (grinding, squealing beyond initial break-in) which may indicate installation issues.
• Check for brake pulls - vehicle should stop straight without pulling to either side.
• After test drive, re-check all lug nut torque values and inspect for any fluid leaks around calipers.
• After 50-100 miles, re-torque wheel lug nuts and recheck brake fluid level.
• Follow break-in procedure: 200-300 miles of gentle stops, avoid hard braking to allow proper pad bedding to rotors.
