⚠️ Safety & Precautions

• 🛑 Always support the car with jack stands; never work under a car held only by a jack.
• 🧯 Work on a flat, solid surface with the transmission in Park and the parking brake off when removing the rear brakes.
• 🔥 Brakes can get very hot; let them cool completely before starting.
• 😷 Brake dust is harmful; avoid breathing it in and do not blow it with compressed air.
• 🔋 Battery disconnection is not required on this Corolla for rear brake work.
• 📏 Do one side at a time so you can look at the other side as a reference.

📋 Before You Begin

• 🚗 Park your Corolla on level ground, place the transmission in Park, and switch off the engine.
• 🧱 Place wheel chocks in front of and behind at least one front wheel.
• ⛔ Release the parking brake before you remove the rear calipers, otherwise the rear brakes will be clamped.
• 📦 Lay out your new pads and rotors so you know which parts go where before you start.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen rear wheel lug nuts

• Use the 21mm socket and 1/2" drive breaker bar to slightly loosen (crack loose) all five lug nuts on both rear wheels, but do not remove them yet.
• Just break them loose while the car is on the ground.

Step 2: Lift and support the rear of the car

• Place the floor jack under the rear center jack point (under the rear subframe crossmember, near the center).
• Raise the rear of the car high enough so both rear wheels are off the ground.
• Position jack stands under the rear pinch welds or designated support points on both sides and slowly lower the car onto the stands using the floor jack.
• Gently rock the car by hand to confirm it is stable on the jack stands.

Step 3: Remove rear wheels

• Use the 21mm socket and 1/2" drive ratchet to remove the loosened lug nuts from one rear wheel.
• Remove the wheel and set it aside; repeat for the other rear wheel.

Step 4: Inspect the rear brake assembly

• Look at the rear brake: you will see the caliper (the part that squeezes the pads), the bracket that holds the caliper, the pads between the bracket and rotor, and the rotor (the disc).
• Note how pads sit in the bracket; you’ll copy this later.

Step 5: Remove the caliper (first side)

• On the back of the caliper, find the two smaller slider bolts (top and bottom).
• Use a 14mm socket and 3/8" drive ratchet to remove the lower caliper bolt, then the upper caliper bolt.
• Carefully slide the caliper off the bracket and pads. If it is stuck, gently pry with a flathead screwdriver between the pad and rotor.
• Hang the caliper from the suspension spring using a bungee cord or wire so it is not hanging by the brake hose.

Step 6: Remove the old brake pads and hardware

• Slide the old pads out of the caliper bracket by hand.
• Remove the metal clips (hardware) from the caliper bracket if your new pads come with new clips.
• Use the wire brush to clean the areas of the bracket where the clips sit, removing rust and debris.
• Lightly spray brake cleaner on the bracket and wipe with shop rags.

Step 7: Remove the caliper bracket

• Locate the two larger bolts that hold the caliper bracket to the hub carrier (behind the rotor).
• Use a 17mm socket and 1/2" drive ratchet or breaker bar to remove both bracket bolts; they may be tight.
• Remove the caliper bracket and set it aside on a clean surface.

Step 8: Remove the old rotor

• Try to pull the rotor straight off the hub by hand.
• If it is stuck due to rust, check for two threaded holes on the rotor face.
• Thread two M8 x 1.25 bolts into these holes and tighten them evenly with a 14mm socket until the rotor pushes off the hub.
• If needed, tap the rotor hat (not the braking surface) with a rubber mallet to help loosen it.

Step 9: Prepare and install the new rotor

• Clean the hub face with the wire brush to remove rust and ensure the new rotor sits flat.
• Apply a very thin film of anti-seize compound on the hub face to prevent future rust (avoid wheel studs).
• Spray the new rotor (both sides) with brake cleaner to remove the protective oil, then wipe dry with shop rags.
• Place the new rotor onto the hub, lining up the lug stud holes.
• Temporarily install one lug nut by hand using the 21mm socket to hold the rotor snug against the hub while you work.

Step 10: Reinstall the caliper bracket

• Position the caliper bracket over the new rotor.
• Install the two bracket bolts by hand to avoid cross-threading.
• Use the 17mm socket and 1/2" drive torque wrench to tighten both bolts to 88 Nm (65 ft-lbs).

Step 11: Install new hardware and prepare new pads

• Snap the new metal hardware clips into the caliper bracket where the pads slide.
• Apply a very thin layer of high-temperature brake grease to the areas of the clips where the pad ears (ends) will contact. Do not get grease on pad friction surfaces or rotor.
• If your pads have shims, make sure they are properly attached to the back of each pad.

Step 12: Compress the caliper piston

• Place an old brake pad over the caliper piston face inside the caliper.
• Use a C-clamp or caliper compressor tool to slowly push the piston straight back into the caliper until it is fully seated.
• Watch the brake fluid reservoir under the hood to ensure it does not overflow; if it gets very full, remove a little fluid with a clean syringe or turkey baster.
• Compress slowly to avoid damaging seals.

Step 13: Install new brake pads

• Slide the new inner and outer pads into the caliper bracket, matching the original positions (inner pad usually has a wear indicator tab if present).
• Make sure the pads move smoothly in the clips, not loose but not tight.

Step 14: Reinstall the caliper over the new pads

• Remove the temporary lug nut holding the rotor if it interferes with caliper installation, then hold the rotor by hand if needed.
• Lower the caliper over the new pads and onto the bracket.
• Align the caliper slider bolt holes.
• Install the upper and lower caliper slider bolts by hand first.
• Use the 14mm socket and 3/8" drive torque wrench to tighten both slider bolts to 27 Nm (20 ft-lbs).

Step 15: Repeat for the other rear side

• Follow Steps 5 through 14 on the other rear wheel.
• Doing both sides ensures even braking and wear.

Step 16: Reinstall rear wheels

• Place the rear wheel back on the hub and install all five lug nuts by hand.
• Use the 21mm socket and 1/2" drive ratchet to snug the lug nuts in a star pattern while the car is still on jack stands (do not fully torque yet).

Step 17: Lower the car and torque lug nuts

• Use the floor jack to lift the rear of the car slightly and remove the jack stands, then lower the car fully to the ground.
• Use the 21mm socket and 1/2" drive torque wrench to tighten all rear wheel lug nuts in a star pattern to 103 Nm (76 ft-lbs).

Step 18: Pump the brake pedal

• Before driving, sit in the driver’s seat and press the brake pedal slowly 10–15 times until it becomes firm.
• This moves the pistons out to contact the new pads against the rotors.

✅ After Repair

• 🧪 With the engine running and in Park, press the brake pedal several times to confirm a firm feel.
• 🚗 Test the brakes at low speed in a safe area, checking for noises, vibration, or pulling to one side.
• 🛢 Check the brake fluid level in the master cylinder; adjust if needed to the MAX line using the correct brake fluid type (DOT 3 or as specified on the cap).
• 🛞 Re-check the rear wheel lug nut torque after about 50–100 km of driving.
• 🔥 Bed-in the new pads: make 5–8 smooth stops from about 40–50 km/h down to 10 km/h with gentle-to-medium braking, allowing some cool-down between stops. Avoid hard braking for the first 200–300 km if possible.
