🔧 Optima - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, unbolt the brake caliper and bracket, replace the rotor, then install new pads. This restores braking performance, reduces vibration/pulsation, and helps prevent uneven pad wear.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• ⚠️ Support the car with jack stands; never rely on a floor jack alone.
• ⚠️ Wear safety glasses and a dust mask; brake dust is harmful—do not blow it with compressed air.
• ⚠️ Hybrid safety: you are not servicing high-voltage parts here—do not touch orange cables or hybrid components.
• ⚠️ Keep brake fluid off paint; it damages finishes quickly.
• ⚠️ Do not press the brake pedal with the caliper removed.
• ✅ Battery disconnect is not required for this front brake service.

📋 Before You Begin

• Park on level ground, shift to Park, and chock the rear wheels.
• Loosen the front lug nuts 1/2 turn using a 21mm socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir; you’ll watch the level as you compress the caliper piston.
• “Caliper” is the clamp that squeezes the pads.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of the car

• Place wheel chocks behind the rear tires.
• Lift the front using a floor jack at the front center jacking point.
• Set the car onto jack stands at the approved pinch weld points.
• Remove both front wheels using a 21mm socket and ratchet.

Step 2: Remove the brake caliper (do not let it hang)

• Turn the steering wheel to give yourself room at the side you’re working on.
• Remove the two caliper slide bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket and support it with a brake caliper hanger hook.
• “Slide bolts” are the smaller bolts holding the caliper.

Step 3: Remove the old pads and caliper bracket

• Pull the brake pads out of the bracket by hand (use a flat trim tool if they’re stuck).
• Remove the caliper bracket bolts using a 17mm socket and breaker bar.
• Torque to 98-112 Nm (72-83 ft-lbs) when reinstalling these bracket bolts.

Step 4: Remove the rotor

• If your rotor has a retaining screw, remove it using a Phillips screwdriver #3.
• Pull the rotor off the hub. If it’s seized, tap around the hat (center “bowl”) with a rubber mallet until it breaks free.
• Clean the hub face with a wire brush so the new rotor sits flat.
• A dirty hub can cause brake vibration.

Step 5: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray over a catch pan, then wipe clean.
• Install the new rotor onto the hub.
• If equipped, reinstall the retaining screw using a Phillips screwdriver #3 (snug only).

Step 6: Service the bracket hardware and prepare new pads

• Remove old pad clips from the bracket (use a flat trim tool if needed).
• Install new clips from the front pad hardware/abutment clip kit.
• Apply a thin film of brake lubricant where the pad “ears” slide on the clips.
• Grease goes on metal contact points, not friction surfaces.

Step 7: Reinstall the caliper bracket

• Position the bracket over the rotor and start the bolts by hand.
• Apply medium-strength threadlocker (blue) to the clean bracket bolt threads.
• Tighten using a 17mm socket and torque wrench.
• Torque to 98-112 Nm (72-83 ft-lbs)

Step 8: Compress the caliper piston

• Check the brake fluid reservoir under the hood—if it’s near “MAX,” remove a little fluid into a catch pan to prevent overflow.
• Place an old pad against the piston face, then use a C-clamp (6" minimum) to slowly push the piston fully back.
• Go slow to avoid pushing fluid too fast.

Step 9: Install new pads and reinstall the caliper

• Install the new inner and outer pads into the bracket by hand.
• Reinstall the caliper over the pads.
• Install and tighten the slide bolts using a 14mm socket and torque wrench.
• Torque to 25-30 Nm (18-22 ft-lbs)

Step 10: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a 21mm socket and torque wrench.
• Torque to 88-108 Nm (65-80 ft-lbs)

Step 11: Restore pedal feel before moving the car

• With the car still in Park, pump the brake pedal 8-12 times until it feels firm.
• Recheck brake fluid level and top off only if needed.

✅ After Repair

• Start the car and confirm there are no warning lights related to braking.
• Do a slow test in a safe area: verify the car stops straight and no grinding noises are present.
• Bed-in (break-in) the pads: do 8-10 moderate stops from ~35 mph to ~5 mph, allowing 30-60 seconds between stops to cool slightly.
• Recheck lug nut torque after 25-50 miles using a torque wrench.
