🔧 Impala - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake caliper and bracket, replace the rotor, and install new brake pads with the included hardware clips. This restores safe stopping power and fixes pulsing or grinding caused by worn pads/warped rotors.

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

⚠️ Safety & Precautions

• Work on level ground and support the car with jack stands—never rely on a floor jack alone.
• Brake dust is harmful; wear a dust mask and avoid blowing dust with compressed air.
• Brakes can be hot; let everything cool before touching rotors/calipers.
• Do not let the caliper hang by the brake hose; support it with a hook/strap.
• No battery disconnect is required for front brakes on your Impala.

📋 Before You Begin

• Park on level ground, turn the engine off, and chock the rear wheels.
• Loosen the front lug nuts about 1/2 turn using a 22mm lug socket and breaker bar before lifting.
• Lift the front and support the pinch weld/subframe points with jack stands.
• Turn the steering wheel to give more room (left for right side work, right for left side work).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the wheel

• Remove the lug nuts using a 22mm lug socket and ratchet/breaker bar.
• Remove the wheel and set it under the car as a backup safety support.

Step 2: Locate the caliper, pads, and bracket

• The caliper is the part that squeezes the pads; the caliper bracket is the heavy mount that holds the pads in place.
• Turn the steering for more access if needed.

Step 3: Remove the caliper (do not stretch the hose)

• Remove the caliper guide pin bolts using a 13mm socket or wrench.
• Lift the caliper off the bracket. Use a caliper hanger hook to support it from the strut spring.
• Never let the caliper hang by the hose.

Step 4: Remove the old pads and hardware clips

• Slide the pads out by hand. If they’re stuck, gently pry with a flathead screwdriver.
• Remove the stainless hardware clips from the bracket.

Step 5: Remove the caliper bracket

• Remove the bracket bolts using an 18mm socket and breaker bar.
• Set the bracket aside.
• On reassembly: Torque to 170 Nm (125 ft-lbs)

Step 6: Remove the rotor

• Pull the rotor straight off the hub.
• If it’s rust-stuck, tap the rotor hat area with a rubber mallet until it breaks free.

Step 7: Clean the hub surface

• Spray the hub face with brake cleaner spray and scrub with a wire brush.
• Wipe clean with shop towels.
• A clean hub helps prevent brake pulsation.

Step 8: Install the new rotor

• Spray both sides of the new rotor with brake cleaner spray and wipe with shop towels (removes packing oil).
• Place the rotor onto the hub.
• Hold it in place by threading on one lug nut by hand (temporary).

Step 9: Reinstall the caliper bracket and new hardware clips

• Reinstall the bracket using the 18mm socket.
• Torque to 170 Nm (125 ft-lbs)
• Install the new pad hardware clips into the bracket by hand (they snap in).

Step 10: Compress the caliper piston

• Remove the brake master cylinder cap under the hood (loosens pressure).
• Use a C-clamp (6") to slowly push the piston back into the caliper.
• Watch the brake fluid level; if it rises near “MAX,” remove a little with a clean towel.
• Go slow to avoid damaging the piston seal.

Step 11: Install new pads and reinstall the caliper

• Apply a thin layer of brake caliper grease to pad “ears” where they slide on the clips (not on pad friction material).
• Install the inner and outer pads into the bracket.
• Set the caliper over the new pads and line up the guide pin holes.
• Install guide pin bolts using a 13mm socket or wrench.
• Torque to 28 Nm (21 ft-lbs)

Step 12: Reinstall the wheel

• Put the wheel on and hand-thread all lug nuts.
• Lower the car until the tire just touches the ground.
• Tighten lug nuts in a star pattern using a torque wrench.
• Torque to 140 Nm (103 ft-lbs)

Step 13: Repeat on the other front wheel

• Repeat the same steps on the other side.
• Do one side at a time to avoid confusion.

✅ After Repair

• Before moving the car, pump the brake pedal 10-15 times until it feels firm (this seats the pads).
• Check brake fluid level and reinstall the master cylinder cap.
• Start the engine and confirm the pedal stays firm.
• Test drive at low speed first. Listen for grinding and confirm straight braking.
• Pad bedding (recommended): make 6-10 moderate stops from 35 mph down to 5 mph, allowing 30-60 seconds between stops for cooling. Avoid hard stops for the first 200 miles.
