🔧 Equinox - Rear Brake Pads & Rotors Replacement

You’ll be removing the rear wheels, calipers, and rotors, then installing new rotors and pads on your Equinox. This restores braking power and prevents vibration or grinding from worn parts.

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

⚠️ Safety & Precautions

• 🔹Always work on a cool brake system; hot brakes can burn skin quickly.
• 🔹Park on a flat surface, put the transmission in Park, and chock (block) the front wheels so the vehicle cannot roll.
• 🔹Support the Equinox with jack stands; never rely on the floor jack alone.
• 🔹Wear safety glasses and a dust mask; brake dust is harmful if inhaled.
• 🔹Do not press the brake pedal with a caliper removed; you can push the piston out.
• 🔹Your Equinox uses a cable parking brake at the rear. Make sure the parking brake is fully released before starting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Support the Rear of the Vehicle

• Use the 19mm socket and breaker bar 1/2" to slightly loosen both rear wheel lug nuts (about 1/2 turn) while the Equinox is still on the ground.
• Position the floor jack (rated 3-ton minimum) under the rear jacking point (center of rear subframe or specified pinch weld area).
• Raise the rear of the vehicle until both rear wheels are off the ground.
• Place jack stands (rated 3-ton minimum) securely under the rear pinch welds or frame points on both sides and slowly lower the vehicle onto them.
• Give the vehicle a firm push to confirm stability.

Step 2: Remove Rear Wheels

• Use the 19mm socket and 1/2" drive ratchet to remove the rear wheel lug nuts completely.
• Remove both rear wheels and set them aside.

Step 3: Inspect the Rear Brake Assembly

• Look at the caliper, caliper bracket, rotor, and parking brake cable at each rear wheel so you understand how they sit before removal.
• Take a photo for reference if you like.

Step 4: Remove Rear Caliper (First Side)

• Turn the steering wheel is not needed for rear; just work from behind the wheel hub.
• On the back of the caliper, locate the two smaller guide pin bolts (usually 14mm heads).
• Use the 14mm socket and 3/8" drive ratchet to loosen and remove the upper and lower caliper guide pin bolts.
• Gently pry the caliper away from the rotor using a flathead screwdriver (medium) if it feels stuck.
• Lift the caliper off the pads and support it with a bungee cord or wire hanger from the suspension spring so it does not hang by the hose.

Step 5: Remove Old Pads and Hardware

• Slide the old brake pads out of the caliper bracket by hand.
• Note how the pads are positioned (inner vs outer pad) for reassembly.
• Remove the metal clips (hardware) from the caliper bracket using a flathead screwdriver (medium) if necessary.

Step 6: Remove Caliper Bracket and Rotor

• Find the two large caliper bracket bolts (behind the rotor, usually 18mm heads).
• Use the 18mm socket, breaker bar 1/2", or 1/2" drive ratchet to loosen and remove both bracket bolts.
• Remove the caliper bracket and set it on a clean surface.
• Pull the rotor straight off the hub. If it is stuck from rust, tap around the rotor hat (center area) with a rubber mallet or small hammer until it loosens, then remove it.

Step 7: Clean Hub and Prepare New Rotor

• Use a wire brush (steel) to clean rust and debris from the wheel hub surface where the rotor sits.
• Wipe the hub with a shop rag and some brake cleaner spray.
• Apply a very thin layer of anti-seize compound to the hub face to prevent the new rotor from sticking in the future. Keep anti-seize off wheel studs.
• Spray the new rotor (both sides) with brake cleaner spray to remove the protective oil coating, then wipe dry with shop rags.

Step 8: Install New Rotor

• Slide the new rotor onto the hub, fully seated against the hub face.
• You can temporarily install one lug nut by hand with the 19mm socket to hold the rotor snug while you work (finger tight only).

Step 9: Service Caliper Bracket & Install New Hardware

• On the caliper bracket, remove the slide pins (the bolts the caliper rode on) if they pull out easily. Note which one goes top and bottom.
• Clean the slide pins with shop rags and inspect the rubber boots. Replace boots if torn.
• Apply a thin layer of high-temperature brake grease to each slide pin and reinstall the pins into the bracket, making sure they move freely.
• Clean the bracket pad contact areas with a wire brush (steel).
• Install the new metal hardware clips from your kit onto the bracket by pressing them into place by hand or with a small wire or pick tool.

Step 10: Reinstall Caliper Bracket

• Position the caliper bracket back over the new rotor.
• Install the two large bracket bolts by hand to avoid cross-threading.
• Use the 18mm socket and 1/2" drive ratchet to snug them down.
• Then use the 18mm socket and torque wrench 1/2" drive to tighten:
• Torque to 130 Nm (96 ft-lbs) for rear caliper bracket bolts.

Step 11: Compress Caliper Piston

• Inspect the caliper piston and rubber boot for damage; do not proceed if torn or leaking.
• Place an old brake pad over the piston face inside the caliper.
• Use a C-clamp (6" or larger) or disc brake piston tool to slowly push the piston back into the caliper until it is fully seated. Turn the clamp slowly so you do not damage the piston.
• Watch the brake fluid level in the master cylinder; it may rise.

Step 12: Install New Brake Pads

• Apply a very light coat of high-temperature brake grease to the pad backing plates where they contact the hardware clips (do not get grease on friction surfaces).
• Slide the new inner and outer pads into the caliper bracket clips by hand. They should move smoothly but not be loose.

Step 13: Reinstall Caliper Over New Pads

• Lower the caliper over the new pads and onto the bracket.
• Align the caliper guide pin bolt holes with the threaded slide pins.
• Install the upper and lower guide pin bolts by hand first.
• Use the 14mm socket and 3/8" drive ratchet to snug them.
• Then use the 14mm socket and torque wrench 3/8" drive:
• Torque to 31 Nm (23 ft-lbs) for rear caliper guide pin bolts.

Step 14: Repeat on the Other Rear Side

• Repeat Steps 4–13 for the other rear wheel.
• Always replace pads and rotors on both sides together.

Step 15: Reinstall Wheels and Lower Vehicle

• Remove any temporary lug nut holding the rotor using the 19mm socket.
• Mount the rear wheel onto the hub and install all lug nuts by hand.
• Use the 19mm socket and 1/2" drive ratchet to snug the lug nuts in a crisscross pattern.
• Raise the Equinox slightly with the floor jack (rated 3-ton minimum), remove the jack stands, then lower the vehicle to the ground.
• Use the 19mm socket and torque wrench 1/2" drive to tighten the lug nuts in a star pattern:
• Torque to 140 Nm (100 ft-lbs) for wheel lug nuts.

Step 16: Pump Brake Pedal and Check Fluid

• Before driving, sit in the driver’s seat and slowly press the brake pedal several times until it becomes firm. This seats the pads against the rotors.
• Check the brake fluid level in the reservoir. If it is above the MAX line, remove a little with a clean syringe or turkey baster. If low, top off with correct brake fluid type listed on the cap.

✅ After Repair

• 🔹With the engine running, press the brake pedal firmly and hold for several seconds; make sure it feels solid and does not sink.
• 🔹Apply and release the parking brake a few times to confirm normal operation.
• 🔹Inspect around both rear calipers and lines for any leaks or rubbing.
• 🔹Perform a short test drive: start at low speeds, gently brake several times to ensure there is no pulling, grinding, or vibration.
• 🔹Bed-in new pads: make 5–10 moderate stops from 30–40 km/h to near stop, allowing cool-down between stops. Avoid hard panic stops at first.
