🔧 Equinox - Rear Brake Pad Replacement

You’ll be removing the rear wheels, unbolting the brake calipers, compressing the pistons, and installing new pads on your Equinox. This restores braking performance and prevents damage to the rotors if your pads are worn.

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

⚠️ Safety & Precautions

• 🛑 Always support the vehicle with jack stands. Never work under a vehicle that’s only held up by a jack.
• 🛑 Work on a cool brake system. Hot brakes can burn you and make parts warp.
• 🛑 Wear safety glasses and mechanic gloves to protect your eyes and hands from dust and sharp edges.
• 🛑 Set the front wheels chocks so the vehicle cannot roll.
• 🛑 Do one side at a time so you can look at the other side for reference.
• 🛑 If your Equinox has an electronic parking brake (EPB) button instead of a lever or foot pedal, you MUST put the system into “service mode” with a proper scan tool. Do not force the pistons back with the EPB engaged, or you can damage the motors.
• 🔋 Battery disconnect is not required for standard rear pad replacement, but do not cycle the ignition or touch the EPB switch while a caliper is off the rotor.

📋 Before You Begin

• 🅿️ Park the Equinox on a flat, solid surface. Put the transmission in PARK and shut off the engine.
• 🧱 Place wheel chocks in front of and behind at least one front wheel.
• 📦 Loosen (but do not remove) the rear wheel lug nuts using the 19mm lug wrench while the vehicle is still on the ground.
• 🚫 If you have an electronic parking brake button, leave the parking brake OFF and do not touch the button again until everything is reassembled.
• 🔧 If you have a scan tool with EPB service mode, connect it now and follow its prompts to place the rear brakes in service mode before removing any caliper (EPB-equipped vehicles only).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Support the Rear of the Vehicle

• Position the floor jack (3-ton) under the rear jacking point or rear subframe crossmember (check the owner’s manual diagram for exact location).
• Raise the rear of the Equinox until both rear wheels are off the ground.
• Place jack stands under the approved rear support points, then slowly lower the vehicle onto the stands with the floor jack.
• Give the vehicle a firm push from the side to confirm it’s stable on the stands.
• Never rely on the jack alone.

Step 2: Remove the Rear Wheels

• Use the 19mm lug wrench to fully remove the loosened lug nuts from one rear wheel.
• Remove the wheel and set it aside where it won’t be a trip hazard.
• Repeat for the other rear wheel if you want both sides raised at once.

Step 3: Inspect the Brake Setup

• Look at the rear brake caliper: you’ll see the caliper body, the bracket behind it, and the rotor.
• Note the pads’ orientation and how the hardware clips sit in the bracket. Take a quick photo for reference.
• If your model has an electronic parking brake motor on the back of the caliper (small electric unit), do not try to turn that motor by hand.

Step 4: Release and Support the Caliper

• On the backside of the caliper, locate the two caliper guide pin bolts (usually using a 13mm socket).
• Use the 13mm socket and socket wrench to loosen and remove the upper and lower guide pin bolts.
• Gently pry the caliper away from the rotor using a flathead screwdriver if needed.
• Hang the caliper from the suspension spring or a sturdy hole using a bungee cord or wire hanger. Do not let it hang by the brake hose.

Step 5: Remove Old Pads and Hardware

• Slide the inner and outer brake pads out of the caliper bracket by hand.
• Remove the metal hardware clips from the caliper bracket using your fingers or a flathead screwdriver.
• Inspect the rotor surface; if it is deeply grooved or heavily rusted, plan on replacing or resurfacing the rotors soon.

Step 6: (Optional) Remove Caliper Bracket for Cleaning

• For a better clean, remove the caliper bracket by loosening the two larger bolts at the back using an 18mm socket and socket wrench.
• Set the bracket on a clean surface.
• Clean the pad contact areas (where the hardware clips sit) thoroughly using the wire brush and brake cleaner.
• Allow the bracket to dry completely.
• When reinstalling later, torque these bolts to 110 Nm (81 ft-lbs) using the torque wrench and 18mm socket.

Step 7: Compress the Caliper Piston

• Place an old brake pad against the caliper piston face.
• Position the brake caliper piston compression tool or a C-clamp between the back of the caliper and the old pad.
• Slowly tighten the tool to push the piston back into the caliper until it is fully seated and flush with the caliper housing.
• If you feel sudden hard resistance and the piston will not move, stop. This may indicate an engaged electronic parking brake or a seized caliper.
• Slow and steady avoids seal damage.

Step 8: Install New Hardware Clips

• Place the new metal hardware clips from the rear brake pad hardware kit into the cleaned slots on the caliper bracket.
• Ensure they are fully seated and not twisted.
• Using a small amount of brake cleaner and the wire brush, clean any remaining rust around the contact areas.

Step 9: Apply Brake Grease to Contact Points

• Apply a very thin layer of high-temperature brake grease to the pad “ears” (the metal ends that slide in the hardware clips).
• Optionally, apply a thin layer to the back of the pads where they contact the caliper piston and the outer caliper fingers to help prevent noise.
• Do not get any grease on the rotor or pad friction surfaces.

Step 10: Install New Rear Brake Pads

• Slide the new inner pad into the caliper bracket first, aligning the ears into the hardware clips.
• Then install the outer pad in the same way.
• Ensure the friction material is facing the rotor on both pads.

Step 11: Reinstall Caliper Over New Pads

• Position the caliper over the new pads and onto the bracket.
• Line up the caliper guide pin holes with the bracket ears.
• Insert the caliper guide pin bolts by hand to avoid cross-threading.
• Use the 13mm socket and socket wrench to snug them down.
• Torque the caliper guide pin bolts to 27 Nm (20 ft-lbs) using the torque wrench and 13mm socket.

Step 12: Repeat on the Other Side

• Repeat Steps 4–11 for the other rear wheel.
• Make sure pad orientation, hardware, and torque are the same on both sides.

Step 13: Reinstall Wheels

• Place the wheel back onto the hub and hand-thread all lug nuts.
• Use the 19mm lug wrench to snug the nuts in a star pattern while the vehicle is still on jack stands.

Step 14: Lower the Vehicle and Torque Lug Nuts

• Use the floor jack to lift the vehicle slightly and remove the jack stands.
• Lower the vehicle completely to the ground.
• Use the torque wrench and 19mm socket to torque each lug nut to 135 Nm (100 ft-lbs) in a star pattern.

Step 15: Pump the Brake Pedal

• Before driving, sit in the driver’s seat and press the brake pedal several times until it feels firm.
• This seats the brake pads against the rotors.

Step 16: If Equipped with Electronic Parking Brake (EPB)

• If you used a scan tool service mode, exit that mode now by following the scan tool instructions.
• With the engine running and your foot on the brake, apply and release the parking brake a few times using the EPB button.
• Listen for abnormal noises from the rear brakes.

✅ After Repair

• 🚗 Take the Equinox for a gentle test drive in a safe area. Start with low speeds and check that the brakes feel firm and responsive.
• 🔊 Listen for grinding, squealing, or rubbing noises. A light, temporary rubbing sound can be normal for new pads, but loud or constant noise is not.
• 🌀 After the drive, feel (carefully) near the wheels to check for any obvious overheating smell or smoke—if present, recheck caliper installation and parking brake operation.
• 📏 Follow a pad break-in (bedding) procedure: make 5–10 moderate stops from 30–40 km/h down to 10 km/h, allowing the brakes to cool slightly between each stop.
• 💡 If the ABS or brake warning light comes on, stop, recheck your work, and scan for codes if possible.
