This repair replaces the front brake pads on your Highlander. Brake pads wear down over time and should be replaced before the friction material gets too thin or starts grinding into the rotors.

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

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface and never rely on a jack alone.
• 🧤 Wear safety glasses and gloves. Brake dust can irritate skin and eyes.
• 🔥 Let the brakes cool completely before starting. Brake parts can stay hot after driving.
• 🚫 Do not press the brake pedal while the caliper is removed.
• 🛑 Support the brake caliper with a bungee cord or wire. Do not let it hang by the brake hose.
• 🔋 Battery disconnect is not required for this front brake pad replacement.

📋 Before You Begin

• 🅿️ Park your Highlander on level ground and shift to Park.
• 🛞 Place wheel chocks behind the rear wheels. Wheel chocks are wedges that keep the vehicle from rolling.
• 🧰 Open the hood and locate the brake fluid reservoir near the driver-side rear of the engine bay.
• 💧 Check the brake fluid level. If it is near the MAX line, remove a small amount with a clean suction tool before compressing the caliper pistons.
• 🚗 Loosen the front wheel lug nuts slightly before lifting the vehicle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use the 21mm lug nut socket and 1/2-inch breaker bar to loosen each front lug nut about half a turn.
• Do not remove the lug nuts yet.
• Loosen while the tires touch ground.

Step 2: Lift and Support the Front of the Vehicle

• Use the floor jack rated 3-ton minimum at the front center jacking point.
• Place jack stands rated 3-ton minimum under the proper front support points.
• Lower the vehicle gently onto the jack stands.
• Give the vehicle a light push to confirm it is stable before working near the wheels.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket and 3/8-inch ratchet to remove the loosened lug nuts.
• Remove both front wheels and set them flat under the side of the vehicle as an extra safety backup.

Step 4: Turn the Steering for Better Access

• Turn the steering wheel toward the side you are working on.
• For the driver side, turn the wheel left. For the passenger side, turn the wheel right.
• This gives more room to reach the brake caliper bolts.

Step 5: Remove the Lower Caliper Slide Bolt

• Use the 14mm socket and 3/8-inch ratchet to remove the lower caliper slide bolt.
• If the slide pin spins, hold it steady with the 17mm open-end wrench.
• A slide pin is the smooth pin that lets the caliper move evenly as the pads wear.

Step 6: Swing the Caliper Up

• Use the flathead screwdriver medium to gently pry the caliper upward if it is tight.
• Swing the caliper upward like opening a door.
• Use the bungee cord 24-inch to support the caliper from the strut spring.
• Do not stretch, kink, or pull on the rubber brake hose.

Step 7: Remove the Old Brake Pads

• Slide the inner and outer brake pads out of the caliper bracket by hand.
• If they are stuck, use the flathead screwdriver medium to carefully wiggle them free.
• Look at the old pads. Uneven wear may mean a sticking slide pin or caliper issue.

Step 8: Remove and Clean the Pad Hardware

• Use the flathead screwdriver medium to remove the old metal pad clips from the caliper bracket.
• Use the small wire brush to clean the bracket areas where the clips sit.
• Spray the bracket lightly with brake cleaner aerosol can.
• Brake cleaner is a fast-drying spray that removes brake dust, grease, and grime.

Step 9: Install New Brake Pad Hardware

• Press the new front brake pad hardware kit clips into the caliper bracket by hand.
• Make sure each clip sits fully flat and does not rub the rotor.
• Apply a thin film of high-temperature brake lubricant to the pad contact points on the clips.
• Do not get lubricant on the rotor or pad friction surface.

Step 10: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use the C-clamp 6-inch or brake caliper piston compression tool to slowly push the piston back into the caliper.
• Watch the brake fluid reservoir while compressing the piston. Fluid level will rise.
• Go slowly to avoid overflowing the reservoir.
• Slow pressure protects the hydraulic system.

Step 11: Install the New Brake Pads

• Install the new front brake pad set into the caliper bracket by hand.
• The friction material faces the rotor.
• Make sure the pads slide smoothly in the new hardware clips.
• If the pads bind, remove them and clean the bracket again with the small wire brush.

Step 12: Lower the Caliper Over the Pads

• Remove the bungee cord 24-inch while holding the caliper securely.
• Lower the caliper over the new pads by hand.
• If it does not fit, use the C-clamp 6-inch or brake caliper piston compression tool to compress the piston a little more.

Step 13: Reinstall the Caliper Slide Bolt

• Start the lower slide bolt by hand to avoid cross-threading.
• Use the 14mm socket and 3/8-inch ratchet to snug the bolt.
• Hold the slide pin with the 17mm open-end wrench if needed.
• Use the torque wrench rated to 100 ft-lbs with the 14mm socket and tighten the caliper slide bolt to Torque to 34 Nm (25 ft-lbs).

Step 14: Repeat on the Other Front Side

• Repeat Steps 4 through 13 on the other front wheel.
• Always replace front brake pads in pairs so braking stays even.

Step 15: Reinstall the Front Wheels

• Place each front wheel back onto the hub.
• Start all lug nuts by hand.
• Use the 21mm lug nut socket and 3/8-inch ratchet to snug the lug nuts in a star pattern.

Step 16: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack rated 3-ton minimum to lift the front slightly off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower the vehicle until the tires just touch the ground.
• Use the torque wrench rated to 100 ft-lbs with the 21mm lug nut socket to tighten lug nuts in a star pattern to Torque to 103 Nm (76 ft-lbs).
• Lower the vehicle fully.

Step 17: Pump the Brake Pedal

• Sit in the driver seat and press the brake pedal slowly several times.
• The pedal will feel soft at first, then become firm.
• Do not drive until the brake pedal feels firm.

✅ After Repair

• ✅ Check the brake fluid level and make sure it is between MIN and MAX.
• ✅ Look behind both front wheels for leaks or anything loose.
• ✅ Start the engine and press the brake pedal again until it feels firm.
• ✅ Test drive slowly in a safe area first.
• ✅ Bed in the new pads by making several gentle stops from about 30 mph, allowing time between stops for cooling.
• ✅ Avoid hard braking for the first 100-200 miles unless needed for safety.
• ✅ Recheck lug nut torque after your first short drive: Torque to 103 Nm (76 ft-lbs).
