🔧 ILX - Rear Brake Pads & Rotor Replacement

You’ll remove the rear wheels, take off the rear brake calipers and brackets, replace the rotors, then install new pads and reassemble everything to factory torque. This restores braking performance and prevents vibration, noise, and uneven wear.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Assumption: your ILX uses a rear caliper piston that must be rotated to retract (common Honda/Acura design).

⚠️ Safety & Precautions

• Work on level ground and use jack stands—never rely on a jack alone.
• Chock the front wheels and keep the transmission in Park.
• Release the parking brake before starting (rear brakes won’t come apart correctly if it’s on).
• Brake dust is harmful—wear a mask and use brake cleaner, not compressed air.
• Do not let the caliper hang by the brake hose; support it with a hook/strap.
• Check brake fluid level often; retracting pistons can overflow the reservoir.

📋 Before You Begin

• Park on level ground, turn the engine off, and put the transmission in Park.
• Release the parking brake fully.
• Place wheel chocks at the front wheels.
• Open the hood and loosen the brake fluid reservoir cap (don’t remove it completely). This helps fluid move back when you retract the pistons.
• Crack the rear wheel lug nuts loose 1/2 turn using a 19mm socket and breaker bar before lifting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Lift the rear with a floor jack at the correct jacking point.
• Set the car onto jack stands and lightly shake the car to confirm it’s stable.
• Remove the rear wheels using a 19mm socket.

Step 2: Remove the rear caliper

• Turn the steering wheel slightly if it gives you more room to work (optional).
• Locate the two caliper slide pin bolts on the back of the rear caliper.
• Remove the slide pin bolts using a 12mm socket (some setups may use 14mm socket).
• Lift the caliper off the bracket and hang it with a bungee cord or caliper hook.
• Never let it hang by the hose.

Step 3: Remove old pads and hardware

• Slide the old pads out of the bracket by hand; use a flat trim/pry tool if they’re stuck.
• Remove the pad clips/hardware from the bracket using a small pick tool.
• Clean the bracket pad “shelves” with a wire brush and a quick spray of brake cleaner.

Step 4: Remove the caliper bracket

• Remove the two caliper bracket bolts using a 17mm socket and breaker bar.
• Set the bracket aside.
• On reassembly, Torque to 88 Nm (65 ft-lbs).

Step 5: Remove the old rotor

• If equipped with rotor set screws, remove them using a Phillips screwdriver #2.
• Pull the rotor straight off. If it’s stuck, tap around the rotor “hat” with a rubber mallet to break rust loose.
• Clean the hub face with a wire brush, then apply a very thin film of anti-seize compound to the hub (keep it off the studs).

Step 6: Install the new rotor

• Spray both sides of the new rotor with brake cleaner and wipe clean (this removes packing oil).
• Install the rotor onto the hub.
• If set screws are used, reinstall them using a Phillips screwdriver #2 (snug only; do not over-tighten).

Step 7: Service slide pins and reinstall the bracket

• Pull the slide pins out of the bracket by hand.
• Wipe old grease off and apply fresh silicone brake lubricant to the smooth pin surface.
• Reinstall the pins and make sure they move smoothly.
• Reinstall the caliper bracket using a 17mm socket.
• Torque to 88 Nm (65 ft-lbs).

Step 8: Install new pad hardware and pads

• Install the new pad clips/hardware into the bracket by hand.
• Apply a thin coat of silicone brake lubricant where the pad ears contact the clips (metal-to-metal contact points only).
• Slide the new pads into place.

Step 9: Retract the rear caliper piston (wind-back)

• Check the brake fluid reservoir level under the hood; siphon a little into a catch pan if it’s near MAX.
• Use a brake caliper wind-back tool (specialty) to rotate and push the piston back into the caliper.
• A wind-back tool is a tool that twists the piston while pressing it in (rear parking-brake calipers often require rotation, not just pushing).
• Stop when the piston face sits flush enough to fit over the new, thicker pads.

Step 10: Reinstall the caliper

• Place the caliper over the new pads and onto the bracket.
• Install the slide pin bolts using a 12mm socket (or 14mm socket, depending on your caliper).
• Torque to 34 Nm (25 ft-lbs).

Step 11: Reinstall wheels

• Reinstall the wheels and hand-thread the lug nuts.
• Lower the car off the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a 19mm socket and torque wrench.
• Torque to 108 Nm (80 ft-lbs).

✅ After Repair

• With the engine off, pump the brake pedal 10-15 times until it feels firm (this seats the pads against the rotors).
• Check brake fluid level and top off only if needed (use the correct DOT brake fluid shown on the reservoir cap).
• Re-apply and release the parking brake a few times to confirm it holds and releases normally.
• Do a careful test drive: start slow, confirm normal stopping, and listen for scraping or grinding.
• Pad bedding (recommended): make 6-10 moderate stops from ~50 km/h to ~15 km/h with cool-down driving between stops. Avoid hard stops and holding the pedal at a stop while brakes are hot.
