🔧 Optima - Front Brake Pad Replacement

You’ll be removing the front wheels, taking the brake caliper off, swapping the old pads for new ones, and then compressing the caliper piston so everything fits back together. This restores safe stopping power and prevents rotor damage when pads get thin.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands; never rely on a jack alone.
• 🛑 Do not press the brake pedal while the caliper is off the rotor.
• 🛑 Brakes may contain dust—avoid blowing it; use brake cleaner and wear a dust mask.
• 🛑 Keep brake fluid off paint; it can damage the finish.
• 🛑 No battery disconnect is required for this job.

📋 Before You Begin

• Park on level ground, shift to P, and set the parking brake.
• Place wheel chocks behind both rear tires.
• Crack the front wheel lug nuts loose 1/2 turn before lifting (use 21mm socket and breaker bar).
• Open the hood and locate the brake fluid reservoir. You will watch the level as you compress the pistons so it doesn’t overflow.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front and remove the wheels

• Use a floor jack to lift the front at the proper jacking point, then set the car securely on jack stands.
• Remove the lug nuts using a 21mm socket and ratchet, then remove both front wheels.

Step 2: Locate the caliper and remove the caliper bolts

• Turn the steering wheel to give yourself room to work on one side.
• On the back of the caliper, remove the two slide pin bolts using a 14mm socket and ratchet.
• Lift the caliper off the bracket and hang it from the suspension spring with a brake caliper hanger hook. Never let it dangle by the hose.
• Reinstall later and Torque to 22–27 Nm (17–20 ft-lbs).
• Slide pins are the “moving” bolts.

Step 3: Remove old pads and hardware

• Pull the inner and outer pads out of the bracket by hand. If stuck, gently pry with a flathead screwdriver.
• Remove the stainless pad clips (abutment clips) from the bracket.

Step 4: Compress the caliper piston

• Place one old brake pad against the piston face.
• Use a C-clamp (6 inch minimum) to slowly press the piston fully back into the caliper.
• Check the brake fluid reservoir as you compress. If it rises near the MAX line, pause and remove a small amount of fluid.
• Go slow to avoid fluid overflow.
• A C-clamp is a screw clamp that presses parts together.

Step 5: Clean and prep the bracket

• Use a wire brush to clean rust from the pad clip “seats” on the bracket.
• Spray the area with brake cleaner and let it dry.
• Install the new pad clips from the hardware kit.
• Apply a thin film of disc brake lubricant where the pad ears contact the clips (metal-to-metal contact points only).

Step 6: Install the new pads

• Slide the new inner and outer pads into the bracket.
• If your pads have a wear indicator (“squealer” tab), match its position to how the old set was installed on that side.

Step 7: Reinstall the caliper

• Set the caliper back over the new pads.
• Install the two slide pin bolts using a 14mm socket and ratchet.
• Final tighten with a torque wrench: Torque to 22–27 Nm (17–20 ft-lbs).

Step 8: Repeat on the other front wheel

• Do the exact same procedure on the other side. Always replace pads in pairs.

Step 9: Reinstall wheels and torque lug nuts

• Reinstall both wheels and hand-thread all lug nuts.
• Lower the car using the floor jack, then remove the jack stands and set the car fully down.
• Tighten lug nuts in a star pattern using a torque wrench: Torque to 88–108 Nm (65–80 ft-lbs).

✅ After Repair

• With the car on the ground, pump the brake pedal slowly 8–12 times until it feels firm.
• Check the brake fluid level and adjust to the proper level (do not overfill).
• Start the engine and hold the brake—confirm normal pedal feel.
• Test-drive at low speed first and confirm no pulling, grinding, or warning lights.
• Pad bed-in: make 6–10 moderate stops from ~30 mph to 5 mph, with cool-down between stops.
