🔧 Traverse - Front Brake Pads and Rotor Replacement

This is a solid intermediate DIY job. You’ll replace both front rotors, both pairs of front pads, and the pad hardware. Work on one side at a time so the assembled side remains your reference.

Your Traverse uses low-drag front calipers. GM specifically directs technicians to use hand tools on the caliper bolts, hold the guide pin while loosening or tightening them, and compress the pistons slowly. static.nhtsa.gov

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

📋 Before You Begin

• 🚙 Park on solid, level ground and place the transmission in Park.
• 🧱 Chock both sides of both rear tires.
• 🛑 Release the electronic parking brake. It operates the rear brakes and doesn’t need service mode for this front repair.
• 🧴 Open the hood and inspect the brake-fluid reservoir. If it’s near the MAX line, remove a small amount before compressing the pistons.
• 📸 Photograph the pad orientation, wear indicator, clips, and brake-hose routing before disassembly.
• 🔩 Loosen each front wheel nut about one-quarter turn with the 21mm socket and breaker bar before lifting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front

• Use the 3-ton floor jack at an approved front lifting point.
• Position the 3-ton jack stands under the reinforced front support points.
• Lower your Traverse onto the stands, then gently shake the body to confirm it’s stable.
• Remove both front wheels using the 21mm socket and 3/8-inch ratchet.

Step 2: Inspect the brake assembly

• Check the rubber brake hose for cracks, wetness, twisting, or bulges.
• Compare the inner and outer pad thickness. Major uneven wear can indicate a seized guide pin, sticking pad, restricted hose, or binding caliper piston.
• GM documented uneven front-pad wear on this brake design. Don’t hide a sticking component under new pads. static.nhtsa.gov

Step 3: Create piston clearance

• Use the large flat-blade screwdriver between the old outer pad and rotor to move the caliper outward slightly.
• Apply slow, gentle pressure. Don’t gouge a brake hose or use the new rotor as a pry surface.
• Watch the reservoir while the pistons move inward. Remove excess fluid if it approaches the top.

Step 4: Remove the caliper

• Use the 14mm socket and 3/8-inch ratchet to remove the upper and lower caliper guide-pin bolts.
• Use the 17mm open-end wrench to hold each guide pin straight while turning its bolt.
• Don’t let the wrench press against or damage the caliper body.
• Lift off the caliper and support it with a caliper hanger hook.
• Don’t disconnect the brake hose. Bleeding isn’t required unless the hydraulic system is opened.

Step 5: Remove the old pads and hardware

• Remove the inner and outer pads from the bracket by hand.
• Use the flat-blade screwdriver to lift out the stainless pad-support clips.
• Note where the pad wear indicator sits so the replacement pad matches the original orientation.

Step 6: Remove the caliper bracket

• Use the 18mm socket and 1/2-inch breaker bar to remove both caliper-bracket bolts.
• Hold the bracket as the final bolt comes out. It’s heavier than it looks.
• Place the bracket and bolts on a clean surface.

Step 7: Remove the old rotor

• Pull the rotor straight off the wheel hub.
• If rust holds it, strike the rotor hat between the wheel studs using the 2-pound dead-blow hammer.
• Don’t strike the wheel studs or hit the rotor braking surface toward yourself.
• Use the wire brake-cleaning brush to remove rust and scale from the hub face.
• The new rotor must sit completely flat. Rust trapped behind it can cause pedal pulsation.

Step 8: Prepare the new rotor

• Clean both friction surfaces with non-chlorinated brake cleaner and a clean lint-free towel.
• Place the new rotor squarely over the wheel studs.
• Temporarily install one wheel nut by hand to keep the rotor seated during assembly.

Step 9: Service the bracket and guide pins

• Use the flat-blade screwdriver and wire brush to clean the bracket lands where the clips sit.
• Remove one guide pin at a time by hand so they aren’t accidentally swapped.
• Wipe away old lubricant and inspect the pins, boots, and bores for corrosion or binding.
• Apply a thin coat of high-temperature silicone brake lubricant to each guide pin.
• Reinstall the pins and confirm they slide smoothly while the rubber boots remain seated.
• Install the new stainless hardware clips by hand.
• Lubricate movement points, never friction surfaces.

Step 10: Reinstall the caliper bracket

• Position the bracket over the rotor and start both bolts by hand.
• Use the 18mm socket and 1/2-inch torque wrench for the first tightening pass.
• Torque each bracket bolt first to 150 Nm (111 ft-lbs), then tighten an additional 15-30 degrees.
• Use the torque-angle gauge for the final angle. An angle specification means rotating the bolt by the stated number of degrees after the initial torque.

Step 11: Install the new pads

• Apply a very thin film of silicone brake lubricant where the pad ears contact the stainless clips.
• Keep lubricant completely off the rotor and pad friction material.
• Install the inner and outer pads into the bracket by hand.
• Confirm both pads slide without excessive force or looseness.

Step 12: Compress both caliper pistons

• Place an old brake pad across both pistons.
• Use the dual-piston compression tool or two 6-inch C-clamps to push both pistons inward evenly.
• Compress them slowly while watching the brake-fluid reservoir.
• Stop if either piston tilts, binds, or requires significantly more force than the other.
• GM recommends slow, even piston compression as a check for internal binding. static.nhtsa.gov

Step 13: Reinstall the caliper

• Place the caliper over the new pads without twisting the brake hose.
• Start both guide-pin bolts by hand to prevent cross-threading.
• Use the 17mm open-end wrench to hold the guide pin and the 14mm socket to tighten the bolt.
• Use the 3/8-inch torque wrench and torque each front guide-pin bolt to 72 Nm (53 ft-lbs).
• Remove the temporary wheel nut and rotate the rotor by hand. Light pad contact is normal.

Step 14: Repeat on the opposite side

• Repeat Steps 2-13 on the other front brake assembly.
• Replace pads and rotors on both front sides even if only one side appears badly worn.
• Compare the removed parts for signs of uneven wear or overheating.

Step 15: Reinstall and torque the wheels

• Clean the wheel-to-hub contact surfaces using the wire brake-cleaning brush.
• Install each wheel and start every nut by hand.
• Snug the nuts in a crisscross pattern using the 21mm socket and 3/8-inch ratchet.
• Raise your Traverse slightly with the floor jack, remove the stands, and lower it fully.
• Use the 21mm socket and 1/2-inch torque wrench to tighten the nuts in a crisscross pattern.
• Torque the wheel nuts to 190 Nm (140 ft-lbs). Chevrolet lists this specification in the owner’s manual. chevrolet.com
• Don’t apply oil, grease, or anti-seize to the wheel studs.

✅ After Repair

• 🦶 With the engine off, press the brake pedal slowly several times until it becomes firm.
• 🧴 Check the brake-fluid level and adjust it between MIN and MAX using fresh DOT 3 fluid if necessary.
• 🔍 Start the engine and hold firm pedal pressure for 30 seconds. The pedal shouldn’t continue sinking.
• 🚫 Don’t move your Traverse if the pedal remains soft, a warning light stays on, fluid leaks, or a wheel binds.
• 🛣️ Begin with several cautious stops at walking speed in a safe open area.
• 🔥 Follow the pad manufacturer’s bedding procedure. If none is provided, make 8-10 moderate stops from approximately 30 mph to 5 mph without activating ABS.
• 🌡️ Drive several minutes between stop groups to let the brakes cool. Don’t sit stopped with the pedal clamped hard immediately after bedding.
• 🔧 Recheck wheel-nut torque after approximately 50 miles.
