📋 Before You Begin

• 🅿️ Park your Highlander on level ground and shift to Park.
• 🅿️ Set the parking brake firmly.
• 🧱 Place wheel chocks behind the rear wheels.
• 🌡️ Let the brakes cool completely before starting.
• 🧴 Open the hood and check the brake fluid reservoir. If it is near the MAX line, remove a small amount with a clean suction tool before compressing the caliper pistons.
• 📘 A brake caliper is the clamp that squeezes the brake pads against the rotor to stop the vehicle.
• 📘 A rotor is the round metal disc behind the wheel that the brake pads press against.

🔨 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 one turn.
• Do this while the tires are still touching the ground so the wheels do not spin.
• Loosen only, do not remove yet.

Step 2: Lift and Support the Front

• Use the floor jack rated 3-ton minimum at the front center jacking point to raise the front of your Highlander.
• Place jack stands rated 3-ton minimum under the proper front side support points.
• Lower the vehicle slowly onto the jack stands.
• Gently shake the vehicle by hand to make sure it is stable before removing 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 place them flat under the sides of the vehicle as an added safety backup.

Step 4: Inspect the Brake Setup

• Put on safety glasses and nitrile gloves.
• Look at the brake caliper, brake pads, and rotor before taking anything apart.
• Use brake cleaner spray and shop rags to clean loose brake dust from the caliper area.
• Do not spray brake cleaner on painted surfaces.

Step 5: Remove the Lower Caliper Slide Pin Bolt

• Use a 17mm open-end wrench to hold the caliper slide pin steady.
• Use a 14mm socket and 3/8-inch ratchet to remove the lower caliper slide pin bolt.
• A slide pin lets the caliper move smoothly as the pads wear.

Step 6: Swing the Caliper Up

• Use the flat-blade screwdriver gently between the old outer pad and caliper if the caliper feels stuck.
• Swing the caliper upward like opening a door.
• Use the brake caliper hanger hook to support the caliper if needed.
• Do not let the caliper hang by the rubber brake hose.

Step 7: Remove the Old Brake Pads

• Slide the old inner and outer brake pads out of the caliper bracket by hand.
• If a pad is stuck, use the flat-blade screwdriver to gently pry it out.
• Pay attention to how the pads and metal clips are positioned before removal.
• Take a phone photo first.

Step 8: Remove and Replace the Pad Hardware

• Use the flat-blade screwdriver to pop the old metal pad support clips out of the caliper bracket.
• Clean the bracket contact areas with brake cleaner spray and shop rags.
• Install the new clips from the front brake pad hardware kit by pressing them into the same positions.
• The clips must sit flat and fully seated.

Step 9: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use the disc brake piston compressor tool to slowly push the piston fully back into the caliper.
• A piston is the round part inside the caliper that pushes the pad into the rotor.
• Watch the brake fluid reservoir while compressing the piston so it does not overflow.
• Go slowly to protect seals.

Step 10: Lubricate the Contact Points

• Apply a thin layer of synthetic brake lubricant to the pad ears where they touch the new metal clips.
• Use only a light coating. Too much grease can attract dirt.
• Do not get lubricant on the pad friction surface or rotor face.

Step 11: Install the New Brake Pads

• Slide the new inner and outer pads into the caliper bracket by hand.
• Make sure the friction material faces the rotor.
• Confirm the pads move slightly in the clips without binding.

Step 12: Lower the Caliper and Install the Bolt

• Swing the caliper down over the new pads by hand.
• If it will not fit, use the disc brake piston compressor tool again to make sure the piston is fully seated.
• Install the lower caliper slide pin bolt by hand first to avoid cross-threading.
• Use the 17mm open-end wrench to hold the slide pin.
• Use the 14mm socket and torque wrench rated 20-100 ft-lbs to tighten the bolt to Torque to 34 Nm (25 ft-lbs).

Step 13: Repeat on the Other Front Side

• Repeat Steps 4 through 12 on the other front brake assembly.
• Always replace front brake pads in pairs so braking stays even.

Step 14: Reinstall the Front Wheels

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

Step 15: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack rated 3-ton minimum to lift the vehicle slightly off the jack stands.
• Remove the jack stands rated 3-ton minimum.
• Lower the vehicle until the tires touch the ground.
• Use the 21mm lug nut socket and torque wrench rated 50-150 ft-lbs to tighten the lug nuts in a star pattern to Torque to 103 Nm (76 ft-lbs).

Step 16: Pump the Brake Pedal

• Sit in the driver seat and press the brake pedal slowly several times until it feels firm.
• This moves the caliper pistons back against the new pads.
• Do not drive until the pedal feels firm.

✅ After Repair

• ✅ Check the brake fluid level and make sure it is between MIN and MAX.
• ✅ Start your Highlander and press the brake pedal again to confirm it feels firm.
• ✅ Look behind both front wheels for leaks or anything loose.
• ✅ Take a slow test drive in a safe area before normal driving.
• ✅ Bed in the new pads with several gentle stops from about 30 mph, allowing the brakes to cool briefly between stops.
• ✅ Avoid hard braking for the first 150-200 miles unless needed for safety.
