🔧 Equinox - Rear Brake Pad Replacement

Your Equinox uses rear disc brakes with an electronic parking brake that operates the rear calipers through cables. Replace the pads on both rear wheels, clean the contact points, lubricate the sliding hardware, and compress each caliper piston before reassembly.

Difficulty Level: Beginner | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• ⚠️ Release the electronic parking brake before lifting your Equinox. Do not operate its switch while either rear caliper is removed.
• ⚠️ Chock both front wheels because the parking brake must remain released.
• ⚠️ Support the vehicle with jack stands. Never work under a vehicle supported only by a floor jack.
• ⚠️ Do not inhale brake dust or clean it with compressed air. Use brake cleaner.
• ⚠️ Never allow a caliper to hang from its flexible brake hose.
• ⚠️ Battery disconnection is not normally required. Keep the ignition off and the key away from the vehicle during the repair.
• ⚠️ If the piston will not compress smoothly, stop. A seized caliper or activated parking-brake mechanism requires further diagnosis.

📋 Before You Begin

• Park your Equinox on firm, level ground. Shift the transmission into Park and switch the ignition off.
• Release the electronic parking brake completely. Confirm the red parking-brake indicator is off before switching off the ignition.
• Place wheel chocks firmly against the front and rear of both front tires.
• Open the hood and inspect the brake-fluid reservoir. If it is at the MAX line, remove a small amount before compressing the pistons so it cannot overflow.
• No infotainment service mode or scan-tool parking-brake retraction command is normally required for this cable-operated system.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the rear wheel nuts

• Put on the safety glasses and mechanic’s gloves.
• Use the 22mm deep socket and 1/2-inch breaker bar to loosen each rear wheel nut about one-half turn.
• Do not remove the wheel nuts while the tires are still supporting the vehicle.

Step 2: Raise and support the rear

• Use the 2-ton floor jack at an approved rear lifting point shown in the owner’s manual.
• Position the 2-ton jack stands beneath the reinforced rear support points, then lower the vehicle gently onto them.
• Leave the floor jack lightly touching its lifting point as a backup, without carrying the vehicle’s weight.
• Push the body gently to confirm it is stable before removing a wheel.

Step 3: Remove one rear wheel

• Use the 22mm deep socket and 1/2-inch breaker bar to remove the wheel nuts.
• Remove the wheel and slide it beneath the side of the vehicle as an additional safety measure.
• Complete one side before opening the other side. This leaves an assembled brake available for reference.

Step 4: Inspect the brake assembly

• Use the non-chlorinated brake cleaner and small nylon brake brush to remove loose dust around the caliper and pad edges.
• Inspect the rotor for deep grooves, blue heat spots, heavy rust, or cracking. A damaged or undersized rotor must be resurfaced or replaced before fitting new pads.
• Inspect the brake hose for cracks, wetness, twisting, or swelling.

Step 5: Remove the caliper

• Use the 14mm socket and 3/8-inch ratchet to remove the lower and upper caliper guide-pin bolts.
• If a guide pin rotates, hold its flat section with the 17mm open-end wrench while loosening the bolt with the 14mm socket.
• Lift the caliper away from the bracket. Use the brake caliper hanger to support it from the suspension.
• Do not pull, twist, or place weight on the brake hose or parking-brake cable.

Step 6: Remove the old pads and hardware

• Use the flat-blade screwdriver to lift the inner and outer pads from the caliper bracket.
• Use the flat-blade screwdriver to remove the stainless pad-support clips from the bracket.
• Note the position of any wear-indicator tab before discarding the old pads.
• Photograph the old pad positions before removal.

Step 7: Check and lubricate the guide pins

• Pull each guide pin from its rubber boot by hand. A guide pin allows the caliper to slide and apply both pads evenly.
• Use brake cleaner and the small nylon brake brush to remove old lubricant and contamination.
• Inspect each rubber boot for tears and each pin for rust or pitting. Replace damaged hardware before continuing.
• Apply a thin coat of high-temperature silicone brake lubricant to the smooth guide-pin surfaces.
• Reinsert each pin by hand and confirm it moves smoothly without binding.

Step 8: Compress the caliper piston

• Place one old brake pad against the piston face.
• Use the brake caliper piston compression tool to push the piston slowly and evenly into the caliper bore.
• This piston normally presses straight inward; do not force it to rotate.
• Watch the brake-fluid reservoir while compressing the piston. Stop if fluid approaches the top.
• If the piston binds or requires excessive force, stop and inspect the caliper and parking-brake operation.

Step 9: Install the new hardware and pads

• Use brake cleaner and the small nylon brake brush to clean the caliper-bracket lands where the stainless clips sit.
• Press the new pad-support clips into the bracket by hand until fully seated.
• Apply a very thin film of high-temperature silicone brake lubricant to the pad ears where they contact the clips.
• Do not put lubricant on the rotor or pad friction material.
• Install the new inner and outer pads by hand. Confirm they slide freely in the clips without excessive looseness.

Step 10: Reinstall the caliper

• Remove the brake caliper hanger and position the caliper over the new pads by hand.
• Make sure the brake hose and parking-brake cable are not twisted or trapped.
• Start both guide-pin bolts by hand to prevent cross-threading.
• Hold a rotating guide pin with the 17mm open-end wrench, then tighten each bolt using the 14mm socket and 3/8-inch torque wrench.
• Torque the rear caliper guide-pin bolts to 27 Nm (20 ft-lbs).

Step 11: Repeat on the opposite side

• Use the same listed tools and repeat Steps 3 through 10 on the other rear brake.
• Replace all four rear pads even if one side appears less worn.
• If one side is substantially more worn, inspect the guide pins and caliper for binding.

Step 12: Reinstall the wheels

• Install each rear wheel and start all wheel nuts by hand.
• Use the 22mm deep socket and 1/2-inch breaker bar to snug the nuts in a crossing pattern.
• Use the floor jack to raise the vehicle slightly, remove the jack stands, and lower the vehicle fully.
• Use the 22mm deep socket and 1/2-inch torque wrench to tighten the wheel nuts in a crossing pattern.
• Torque the wheel nuts to 140 Nm (103 ft-lbs).

Step 13: Restore brake-pedal pressure

• With the ignition off, press and release the brake pedal slowly several times until it becomes firm.
• Do not move your Equinox until the pedal feels firm and consistent.
• Check the brake-fluid reservoir and correct the level only with the fluid specification printed on its cap.

✅ After Repair

• Start the engine while holding the brake pedal. Confirm the pedal remains firm and no brake warning stays illuminated.
• Apply and release the electronic parking brake once. Listen for normal operation and confirm the warning indicator turns off.
• Check around both rear calipers and brake hoses for fluid leakage.
• Perform a slow test in a safe area. Confirm the vehicle stops straight and there are no scraping or grinding sounds.
• Bed in the pads with 6-8 moderate stops from approximately 50 km/h to 15 km/h. Avoid coming to a complete stop with hot brakes between passes.
• Drive for several minutes afterward without heavy braking to let the brakes cool.
• Recheck wheel-nut torque after approximately 80-160 km.
