🔧 Equinox - Rear Brake Pad Replacement

You’ll be replacing the rear brake pads on your Equinox and inspecting the rotors so the vehicle can stop safely and quietly. This involves lifting the rear, removing the wheels, pulling the calipers, swapping pads, and compressing the pistons.

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

⚠️ Safety & Precautions

• ⚠️ Always support the vehicle with jack stands; never rely on the floor jack alone.
• ⚠️ Work on a flat, solid surface and set the parking brake off when working on rear calipers so they are not clamped.
• ⚠️ Chock (block) the front wheels so the vehicle cannot roll.
• ⚠️ Brakes and wheels can get very hot; let everything cool before starting.
• ⚠️ Wear safety glasses and mechanic gloves to protect your eyes and hands from dust and sharp edges.
• ⚠️ Brake dust is harmful; avoid blowing it with compressed air. Use brake cleaner instead.
• ⚠️ Do not press the brake pedal with a caliper removed; it can push the piston out.
• ⚠️ Keep brake fluid off paint; it can damage paint quickly. Wipe spills immediately.
• Battery disconnect is not required for this job.

📋 Before You Begin

• Park the Equinox on a level surface with the transmission in PARK.
• Make sure the parking brake is released before working on the rear brakes.
• Place wheel chocks in front of and behind at least one front wheel.
• Loosen rear wheel lug nuts slightly (about half a turn) before lifting the vehicle.
• Gather all tools and parts so you don’t have to search mid-job.
• Open the hood and locate the brake fluid reservoir. Have rags ready in case the fluid level rises when compressing pistons.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and support the rear of the vehicle

• Use the lug wrench (19mm) or 19mm socket to loosen (but not remove) the rear wheel lug nuts on both sides.
• Position the floor jack under the rear center jacking point (under the rear subframe crossmember) and raise the back of the vehicle.
• Place jack stands under the rear pinch welds or recommended support points, then slowly lower the vehicle onto the stands using the floor jack.
• Give the vehicle a gentle push to confirm it is stable on the stands.

Step 2: Remove the rear wheels

• Use the lug wrench or 19mm socket with ratchet to remove the lug nuts completely.
• Remove both rear wheels and set them aside.
• If a wheel sticks, tap tire sidewall with your palm.

Step 3: Inspect the brake assembly

• Look at the caliper (the part that squeezes the pads) and the rotor (the disc).
• Check how the caliper is mounted so you know how it will go back together.
• Note the metal clips that the pads sit in; these will likely be replaced.

Step 4: Remove the caliper slide bolts

• Locate the two smaller bolts on the back of the caliper (top and bottom).
• Use a 13mm socket and 3/8" ratchet to loosen and remove the upper and lower caliper slide bolts.
• Set the bolts aside in a safe place so they don’t get dirty.

Step 5: Remove and support the caliper

• Use a flathead screwdriver to gently pry the caliper away from the rotor if it is stuck.
• Lift the caliper off the bracket and pads.
• Support the caliper with a bungee cord or wire, hanging it from the suspension spring so it does not hang by the brake hose.
• Never let the caliper dangle by the hose.

Step 6: Remove the old brake pads and hardware

• Slide the inner and outer pads out of the caliper bracket by hand.
• Use a flathead screwdriver to carefully pry out the metal pad clips (hardware) from the bracket.
• Discard the old pads and clips.

Step 7: Inspect rotor and parking brake drum

• Spin the rotor by hand and listen for scraping or grinding.
• Check both sides of the rotor surface for deep grooves or heavy rust.
• If you plan to replace the rotor, remove the caliper bracket in the next step and slide the rotor off the hub.

Step 8: Remove caliper bracket and rotor (if replacing rotors)

• Use an 18mm socket and 1/2" ratchet to remove the two large caliper bracket bolts at the back of the knuckle.
• Remove the caliper bracket and set it aside.
• Pull the rotor straight off the hub. If it is stuck, tap around the rotor hat with a rubber mallet if available, or gently with your palm.
• Use a wire brush to clean rust from the hub face where the rotor sits.
• Apply a very thin film of anti-seize compound to the hub face.
• Install the new rotor onto the hub and hold it in place with one lug nut finger-tight using the lug wrench so it sits flat.
• Reinstall the caliper bracket using the 18mm socket and 1/2" ratchet and tighten both bolts.
• Torque caliper bracket bolts to 88 Nm (65 ft-lbs) using the 1/2" drive torque wrench.

Step 9: Clean and prepare the caliper bracket

• If the bracket is still off, you can work on it on a bench; otherwise, work in place.
• Use a wire brush to clean the areas where the pad clips sit (the channels).
• Spray the bracket with brake cleaner over a drip pan and wipe with shop rags.
• Install the new pad hardware clips into the bracket by hand, making sure they snap in fully.
• Apply a small amount of brake grease on the surfaces of the clips where the pad ears will slide. Use only a thin coating.

Step 10: Compress the caliper piston

• Check the brake fluid level under the hood; if it is very full, remove a small amount with a clean rag or syringe so it doesn’t overflow when the piston is pushed back.
• Place an old brake pad over the caliper piston face.
• Use a C-clamp or disc brake piston compressor tool to slowly push the piston back into the caliper bore until it is fully seated.
• Go slowly and keep the piston straight as it moves in.
• If it feels stuck, stop and double-check alignment.

Step 11: Install the new brake pads

• Identify inner vs outer pads (some sets mark them or one will have a wear indicator tab).
• Slide the new inner pad into the inner side of the bracket, making sure the pad ears snap into the new clips.
• Slide the outer pad into the outer side of the bracket the same way.
• Ensure pads can move slightly back and forth in the clips; they should not be jammed tight.

Step 12: Reinstall the caliper

• Position the caliper over the new pads and onto the bracket.
• Align the caliper slide bolt holes with the guide pin holes.
• Apply a small amount of brake grease to the smooth shank of the slide bolts if they are dry (avoid the bolt threads).
• Install the upper and lower slide bolts by hand to avoid cross-threading.
• Use a 13mm socket and 3/8" ratchet to snug them down.
• Torque caliper slide bolts to 31 Nm (23 ft-lbs) using the 3/8" drive torque wrench.

Step 13: Repeat on the other side

• Repeat Steps 4–12 on the other rear wheel.
• Do each side the same way so both match.

Step 14: Reinstall wheels and lower the vehicle

• Install each rear wheel onto the hub and start all lug nuts by hand.
• Use the lug wrench or 19mm socket to snug the lug nuts in a star pattern while the vehicle is still on jack stands.
• Use the floor jack to raise the vehicle slightly, remove the jack stands, then lower the vehicle fully to the ground.
• With the vehicle on the ground, use the 1/2" drive torque wrench and 19mm socket to tighten the lug nuts in a star pattern.
• Torque lug nuts to 140 Nm (103 ft-lbs).

Step 15: Pump the brake pedal and check fluid

• Sit in the driver’s seat and slowly pump the brake pedal several times until it feels firm. This seats the pads against the rotors.
• Check the brake fluid level in the reservoir and adjust if needed so it’s between MIN and MAX.
• Inspect around each caliper for any leaks or loose parts.

✅ After Repair

• Start the engine and press the brake pedal to confirm it feels firm and consistent.
• With the vehicle in a safe area, move slowly forward and gently apply the brakes several times to make sure the rear brakes work smoothly and without noise.
• Listen for grinding, clunking, or metal-on-metal sounds; if heard, stop and re-check pad placement and hardware.
• For the first 300–500 km, avoid very hard stops when possible so the new pads can bed in to the rotors properly.

💰 DIY vs Shop Cost

Shop Cost: $350–$550 (parts + labor) for rear brake pads, and more if rotors are replaced.

DIY Cost: $80–$180 (parts only), depending on pad and rotor quality.

You Save: $270–$370 by doing it yourself!

Shop labor rates vary but typically run $100–$150/hour. This repair takes a shop approximately 1.0–1.5 hours.
