⚠️ Safety & Precautions

• ⚠️ Support your Malibu with jack stands. Never work beneath a vehicle supported only by a jack.
• 🛑 Replace front pads and rotors on both sides to maintain even braking.
• 🧤 Brake dust is harmful. Do not use compressed air; clean it with brake cleaner.
• 🔥 Allow the brakes to cool completely before beginning.
• 🔋 Battery disconnection is not required for this front-brake repair.
• 🚫 Do not press the brake pedal while either front caliper is removed.
• ⚙️ Do not let a caliper hang from its flexible brake hose.
• 💧 Brake fluid damages paint. Clean spills immediately with water.

📋 Before You Begin

• 📍 Park on firm, level ground. Place the transmission in Park and apply the parking brake.
• 🔒 Place wheel chocks securely behind both rear tires.
• 📱 No infotainment service mode or scan-tool command is required for the front brakes.
• 🔍 Open the hood and inspect the brake-fluid level. Remove a little fluid with a plastic syringe if it is near MAX, because retracting the pistons raises the level.
• 📸 Take a picture of each assembled brake before removing parts.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Use the 19mm deep socket and breaker bar to loosen each front wheel nut about one-quarter turn.
• Do not remove the nuts while your Malibu is on the ground.

Step 2: Raise and Support the Front

• Use the 2-ton floor jack at the reinforced front lifting point specified for your Malibu.
• Position the 2-ton jack stands beneath the reinforced side support points.
• Lower the vehicle onto the stands, leave the floor jack lightly supporting the vehicle, and gently shake the body to verify stability.

Step 3: Remove the Front Wheels

• Use the 19mm deep socket and ratchet to remove the wheel nuts.
• Remove both front wheels and slide them beneath the rocker-panel area as an additional precaution.

Step 4: Remove the Brake Caliper

• Turn the steering wheel to provide easier access to the side being serviced.
• Use the flat-blade screwdriver to gently check that the caliper can move on its guide pins.
• Use the 14mm socket and ratchet to remove the upper and lower caliper guide-pin bolts. Hold the guide pin with an appropriate wrench if it begins turning.
• Lift the caliper from the bracket and support it with a caliper hanger hook.
• A caliper hanger is a hook that supports the caliper without straining its hose.
• Never suspend the caliper by the brake hose.

Step 5: Remove the Old Brake Pads

• Pull both pads from the caliper bracket by hand.
• Use the flat-blade screwdriver to remove the stainless-steel pad hardware clips.
• Note the location of any wear indicator before discarding the old pads.
• Compare the inner and outer pad thickness. A major difference can indicate sticking guide pins or a binding caliper.

Step 6: Retract the Caliper Piston

• Place an old brake pad against the caliper piston.
• Open the brake-fluid reservoir cap and cover the surrounding area with clean shop towels.
• Use the brake piston compression tool to press the piston slowly and evenly into the caliper.
• A piston compression tool pushes the hydraulic piston back to make room for thicker new pads.
• Watch the reservoir and remove excess fluid with the plastic syringe before it overflows.
• If the piston binds, stop. Do not force it with large adjustable pliers because the piston or caliper can be damaged.

Step 7: Remove the Caliper Bracket

• Use the 21mm socket, 150mm extension, and breaker bar to remove the two caliper-bracket bolts.
• Remove the bracket and place it on a clean work surface.
• Use the nylon detailing brush and brake cleaner over the drain pan to clean the bracket.

Step 8: Service the Guide Pins and Pad Lands

• Pull each guide pin and rubber boot from the bracket by hand, keeping the upper and lower pins in their original positions.
• Use clean lint-free shop towels and brake cleaner to remove the old lubricant.
• Inspect the pins and boots for rust, scoring, swelling, or tears. Replace damaged parts before continuing.
• Apply a thin coat of high-temperature silicone brake lubricant to the smooth guide-pin surfaces, then reinstall the pins and seat the boots fully.
• Use the wire brush to clean rust from the bracket surfaces beneath the pad hardware.
• Install the new hardware clips by hand, then place a very thin film of silicone brake lubricant where the pad ears contact the clips.
• Keep lubricant away from the pad friction material and rotor faces.
• Thin lubricant layers prevent dirt buildup.

Step 9: Remove the Old Rotor

• Use the Torx T30 bit socket and ratchet to remove the rotor retaining screw, if fitted.
• If the rotor is rusted to the hub, strike the rotor hat between the wheel studs with the rubber mallet.
• Do not strike the wheel studs or the rotor’s thin outer edge.
• Remove the rotor from the hub.

Step 10: Clean the Hub

• Put on safety glasses and use the wire brush to remove rust from the hub face and center pilot.
• Use 400-grit abrasive paper for stubborn raised corrosion.
• Wipe the hub clean with brake cleaner and a lint-free shop towel.
• The new rotor must sit completely flat against the hub. Remaining rust can cause pedal pulsation.

Step 11: Prepare and Install the New Rotor

• Use brake cleaner and clean lint-free shop towels to clean both friction faces of the new rotor.
• Install the rotor over the wheel studs.
• Reinstall the retaining screw with the Torx T30 bit socket. Torque to 9 Nm (80 in-lbs).
• Do not over-tighten the small retaining screw.

Step 12: Reinstall the Caliper Bracket

• Clean the bracket-bolt threads with brake cleaner and a wire brush, then dry them.
• Apply one small drop of medium-strength threadlocker to the clean bracket-bolt threads.
• Install the bracket and start both bolts by hand.
• Use the 21mm socket and torque wrench to tighten both bolts. Torque to 150 Nm (111 ft-lbs).

Step 13: Install the New Brake Pads

• Fit the inner and outer pads into the new hardware clips by hand.
• Confirm that each pad slides freely without excessive looseness.
• Keep all grease and fingerprints away from the pad friction surfaces.

Step 14: Reinstall the Caliper

• Place the compressed caliper over the new pads without twisting the brake hose.
• Start both guide-pin bolts by hand to prevent cross-threading.
• Use the 14mm socket and torque wrench to tighten the guide-pin bolts. Torque to 28 Nm (21 ft-lbs).
• Confirm that the brake hose follows its natural route and cannot contact the tire.

Step 15: Repeat on the Other Side

• Use the same tools and procedure to replace the pads and rotor on the opposite front wheel.
• Compare the completed side with the side you are assembling if any clip position is unclear.

Step 16: Reinstall the Wheels

• Install each wheel and start all five nuts by hand.
• Use the 19mm deep socket and ratchet to snug the nuts in a star pattern.
• Use the floor jack to raise your Malibu slightly, remove the jack stands, and lower it until the tires touch the ground.
• Use the 19mm deep socket and torque wrench to tighten the wheel nuts in a star pattern. Torque to 140 Nm (100 ft-lbs).

Step 17: Restore Brake Pedal Pressure

• With the engine off, press the brake pedal slowly several times until it becomes firm.
• Do not move your Malibu until the pedal feels firm.
• Check the reservoir and adjust to the MAX line with fresh DOT 3 brake fluid if necessary.
• Install the reservoir cap securely and clean any spilled fluid with water.

✅ After Repair

• 🛑 Start the engine and hold firm pedal pressure for 30 seconds. The pedal should remain steady and must not sink toward the floor.
• 🔍 Inspect both front calipers and hoses for leakage before moving your Malibu.
• 🚗 Test the brakes at walking speed in a safe, traffic-free area.
• 🔥 Bed in the pads with 8-10 moderate stops from approximately 50 km/h to 15 km/h. Do not come to a complete stop during each cycle.
• 🌬️ Drive for 5-10 minutes afterward with minimal braking so the brakes can cool.
• 🚫 Avoid hard braking and holding the hot brakes at a complete stop for the first 300 km unless required for safety.
• 🔩 Recheck the wheel-nut torque to 140 Nm (100 ft-lbs) after approximately 80-100 km.
• ⚠️ If the pedal remains soft, the vehicle pulls strongly, grinding continues, or fluid leaks appear, do not drive it.
