🔧 ILX - Front Brake Pad Replacement

Your ILX’s front brake pads wear down over time and need replacement to keep stopping power strong and prevent rotor damage. This job involves removing the front wheels, swinging the caliper out of the way, swapping pads, and compressing the caliper piston so everything fits back together.

Difficulty Level: Intermediate | Estimated Time: 1-2 hours

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands—never rely on a floor jack alone.
• 🧤 Wear safety glasses and mechanic gloves; brake dust is harmful.
• 🔥 Brakes can be hot; let them cool before touching parts.
• 🧴 Don’t let brake fluid overflow when compressing the piston; it can damage paint.
• 🪝 Do not let the brake caliper hang by the hose; support it with a hook.
• 🔒 Keep grease off pad friction material and rotor surfaces.

📋 Before You Begin

• Park on level ground, shift to P, and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Pop the hood and locate the brake fluid reservoir. Loosen the cap (leave it sitting on top) so fluid can move as you compress pistons.
• Tip: Take a quick photo of pad/clip layout.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and raise the front

• Use a 19mm socket and breaker bar to loosen the front wheel lug nuts 1/2 turn (do not remove yet).
• Use a floor jack to lift the front of the car at the front center jacking point.
• Set the car down onto jack stands placed at the approved front support points.

Step 2: Remove the front wheels

• Use a 19mm socket and ratchet to remove the lug nuts, then remove both front wheels.

Step 3: Locate the caliper bolts (slide pin bolts)

• Turn the steering wheel to give yourself space to work.
• Find the two caliper slide pin bolts on the back of the caliper.
• A “slide pin” is the smooth pin the caliper slides on as pads wear.

Step 4: Remove the caliper and support it

• Use a 7mm hex bit socket and ratchet to remove the two caliper slide pin bolts.
• Carefully lift the caliper off the bracket.
• Hang the caliper using a brake caliper hook or small bungee cord so the hose is not stretched.

Step 5: Remove the old pads and hardware

• Slide the old pads out of the bracket by hand. If stuck, use a flathead screwdriver gently.
• Remove the stainless pad clips (hardware) from the bracket.
• Use brake parts cleaner spray and shop towels to clean the bracket contact areas.
• Use a wire brush to remove rust where the clips sit (clean metal helps pads slide freely).

Step 6: Compress the caliper piston

• Place one old brake pad against the caliper piston face.
• Use a C-clamp (6") to slowly press the piston all the way back into the caliper.
• Check the brake fluid reservoir while compressing; remove some fluid with towels if it looks like it will overflow.
• Tip: Go slow to avoid damaging seals.

Step 7: Install new pad hardware and pads

• Install the new stainless clips from the front brake pad hardware kit into the bracket.
• Apply a very thin film of brake caliper grease (silicone) where the pad “ears” touch the clips (metal-to-metal contact points only).
• Install the new pads into the bracket in the same positions as the old ones.

Step 8: Reinstall the caliper

• Lower the caliper over the new pads.
• If the caliper won’t fit, the piston isn’t compressed enough—use the C-clamp (6") again.
• Reinstall the slide pin bolts using the 7mm hex bit socket and ratchet.
• Torque to 34 Nm (25 ft-lbs) using a 3/8" drive torque wrench.

Step 9: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread the lug nuts.
• Lower the car off the jack stands using the floor jack.
• Torque the lug nuts in a star pattern using a 1/2" drive torque wrench.
• Torque to 108 Nm (80 ft-lbs).

Step 10: Pump the brake pedal (critical)

• With the engine OFF, press the brake pedal slowly 10-15 times until it feels firm.
• This seats the pads against the rotors after the piston was pushed back.
• Top off brake fluid if needed and reinstall the reservoir cap snugly.

✅ After Repair

• Start the engine and confirm the brake pedal feels normal (not sinking).
• Do a slow test stop in a safe area to confirm smooth braking and no pulling.
• Check for leaks around the calipers and confirm no warning lights.
• Pad break-in: make 8-10 moderate stops from ~30 mph to ~5 mph, with cooling time between stops.
• Tip: Avoid hard stops for 200 miles.
