⚠️ Safety & Precautions

• ⚠️ Support your Suburban with 6-ton jack stands. Never work beneath a vehicle supported only by a floor jack.
• 🛑 Replace the front pads and rotors on both sides, even if only one side appears worn.
• 🧤 Brake dust can be harmful. Wear safety glasses and nitrile gloves, and never use compressed air to clean the brakes.
• 🔥 Allow the brakes to cool completely before starting.
• 💧 Do not press the brake pedal while a caliper is removed.
• 🔧 Never let the brake caliper hang from its rubber hose.
• 🔋 Battery disconnection is not required for this repair.

📋 Before You Begin

• 📍 Park your Suburban on firm, level pavement. Place the transmission in Park and apply the parking brake.
• 🧱 Place wheel chocks tightly behind both rear tires.
• 🛞 Confirm that the replacement rotors and pads match the original front brake package before disassembly.
• 💧 Open the hood and inspect the brake-fluid reservoir. If it is at the MAX line, remove a small amount with the plastic fluid syringe so it cannot overflow when the caliper pistons are compressed.
• 📱 No infotainment service mode, scan tool, electronic parking-brake retraction, or battery disconnection is required for the front brakes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Use the 22mm deep impact socket and 1/2-inch breaker bar to loosen each front wheel nut about one-quarter turn.
• Do not completely remove the wheel nuts while your Suburban is on the ground.

Step 2: Raise and Support the Front End

• Use the 3-ton floor jack beneath the reinforced front crossmember to raise the front of your Suburban.
• Position the 6-ton jack stands under the left and right frame rails immediately behind the front wheels.
• Lower your Suburban onto the stands. Gently push the body to verify that it is stable.
• Keep the floor jack lightly touching the crossmember as a secondary precaution.

Step 3: Remove Both Front Wheels

• Use the 22mm deep impact socket and 1/2-inch ratchet to remove the wheel nuts.
• Remove both front wheels and slide them flat beneath the frame as an additional safety measure.

Step 4: Compress the Caliper Pistons Slightly

• Use the flat-blade screwdriver through the caliper opening to gently push the old inboard pad away from the rotor.
• Move it only enough to create clearance for caliper removal. Do not damage the rubber piston boots.
• Check the brake-fluid reservoir for rising fluid. Remove excess fluid with the plastic fluid syringe if necessary.

Step 5: Remove the Front Caliper

• Turn the steering wheel to provide better access to the caliper bolts on the side being serviced.
• Use the 18mm six-point socket and 1/2-inch ratchet to remove the upper and lower caliper guide-pin bolts.
• A guide pin is the smooth sliding pin that lets the floating caliper move evenly as the brakes are applied.
• Lift the caliper from the bracket. Suspend it from the suspension with mechanic’s wire.
• Do not twist, stretch, or pull on the brake hose.

Step 6: Remove the Old Brake Pads and Hardware

• Use the flat-blade screwdriver to remove the inner and outer pads from the caliper bracket.
• Use the small hooked pick to remove the old stainless-steel pad hardware from the bracket.
• Note the location of the wear indicator on the original pad so the replacement pad can be installed in the same orientation.

Step 7: Remove the Caliper Bracket

• Use the 21mm six-point socket and 1/2-inch breaker bar to remove the two caliper-bracket bolts.
• These bolts are tight. Keep the socket fully seated and pull the breaker bar steadily.
• Remove the caliper bracket and place it on a clean work surface.

Step 8: Remove the Old Rotor

• Use the Torx T30 bit socket and 3/8-inch ratchet to remove the rotor retaining screw.
• Pull the rotor straight off the hub.
• If the rotor is rusted in place, strike the rotor hat between the wheel studs with the 16-ounce rubber mallet. Do not strike the studs.
• Rotate the rotor while tapping around its center.

Step 9: Clean the Hub and New Rotor

• Place the drain pan beneath the hub.
• Use the hand wire brush to remove rust and debris from the flat hub face.
• Wipe the hub with non-chlorinated brake cleaner and disposable shop towels.
• Use non-chlorinated brake cleaner and shop towels to clean both friction surfaces of the new rotor. New rotors have a protective coating that must be removed unless the packaging specifically identifies them as coated and ready to install.
• Do not apply grease or anti-seize between the rotor and hub.

Step 10: Install the New Rotor

• Place the new rotor over the wheel studs and seat it fully against the hub.
• Install a new retaining screw with the Torx T30 bit socket and 3/8-inch torque wrench.
• Torque the rotor retaining screw to 12 Nm (106 in-lbs).

Step 11: Prepare the Caliper Bracket

• Use the hand wire brush to clean the bracket surfaces beneath the stainless-steel pad hardware.
• Install the new pad hardware by hand. Ensure each clip is completely seated.
• Pull each guide pin from its rubber boot by hand and inspect it for corrosion, scoring, or binding.
• Wipe the guide pins clean with disposable shop towels. Apply a thin layer of high-temperature silicone brake lubricant and reinstall them.
• Do not use petroleum grease because it can damage the rubber boots.
• Confirm that both guide pins slide smoothly and that their boots are fully seated.

Step 12: Reinstall the Caliper Bracket

• Position the bracket over the rotor and start both bracket bolts by hand.
• Use the 21mm six-point socket and 1/2-inch torque wrench to tighten both bolts.
• Torque the caliper-bracket bolts to 230 Nm (170 ft-lbs).

Step 13: Fully Compress the Caliper Pistons

• Place an old brake pad across both caliper pistons.
• Use the dual-piston brake caliper compression tool to press both pistons slowly and evenly into the caliper.
• A caliper compression tool pushes the pistons straight inward without damaging them.
• Watch the reservoir while compressing the pistons. Use the plastic fluid syringe if the fluid approaches the top.
• Stop if a piston binds, tilts, leaks, or will not retract with steady hand pressure.

Step 14: Install the New Brake Pads

• Apply a very thin layer of high-temperature silicone brake lubricant to the pad ears where they contact the stainless-steel hardware.
• Keep lubricant completely off the rotor and pad friction material.
• Install the inner and outer pads into the bracket by hand, matching the original wear-indicator orientation.
• Verify that both pads can move in the hardware without binding.

Step 15: Reinstall the Caliper

• Remove the mechanic’s wire and lower the caliper over the new pads.
• Do not force the caliper or twist the brake hose.
• Start both guide-pin bolts by hand to prevent cross-threading.
• Use the 18mm six-point socket and 1/2-inch torque wrench to tighten the bolts.
• Torque the caliper guide-pin bolts to 100 Nm (74 ft-lbs).

Step 16: Repeat the Repair on the Opposite Side

• Repeat Steps 4 through 15 on the other front wheel using the same listed tools.
• Compare both completed sides before installing the wheels. Confirm that every bolt, clip, boot, and pad is correctly positioned.

Step 17: Reinstall the Front Wheels

• Install both wheels and start all wheel nuts by hand.
• Use the 22mm deep impact socket and 1/2-inch ratchet to snug the nuts in a star pattern.
• Use the 3-ton floor jack to raise your Suburban slightly, remove the 6-ton jack stands, and lower it until the tires touch the ground.
• Use the 22mm deep impact socket and 1/2-inch torque wrench to tighten the wheel nuts in a star pattern.
• Torque the wheel nuts to 190 Nm (140 ft-lbs).

Step 18: Restore Brake Pedal Pressure

• Before starting the engine, slowly press and release the brake pedal several times until it becomes firm.
• Do not move your Suburban until the pedal is firm.
• Check the reservoir and adjust the level with fresh DOT 3 brake fluid. Do not fill above the MAX line.

✅ After Repair

• 🔍 Inspect both calipers, hoses, bleeder screws, and the ground beneath your Suburban for brake-fluid leaks.
• 🚦 Start the engine and hold firm pressure on the brake pedal for 30 seconds. The pedal should remain steady and must not sink toward the floor.
• 🛞 Perform a cautious test at walking speed before entering normal traffic. Verify that your Suburban stops straight without scraping or unusual noise.
• 🔥 Bed in the pads with 8-10 moderate stops from approximately 50 km/h to 15 km/h. Allow about 30 seconds of driving between stops and avoid activating ABS.
• 🅿️ After bedding, drive for several minutes without heavy braking so the brakes can cool. Do not hold the hot brakes firmly at a stop unless needed for safety.
• 🔧 Recheck the wheel-nut torque to 190 Nm (140 ft-lbs) after approximately 80-160 km.
