🔧 Highlander - Front Brake Pad & Rotor Replacement

This repair replaces the front brake pads and front brake rotors on your Highlander. Brake pads create friction to stop the vehicle, and rotors are the metal discs the pads clamp onto.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack alone.
• ⚠️ Use jack stands before putting any part of your body near the wheel area.
• ⚠️ Brake dust can be harmful. Do not blow it with compressed air.
• ⚠️ Front brakes may be hot after driving. Let them cool before starting.
• ⚠️ Do not press the brake pedal while the caliper is removed.
• ⚠️ Support the brake caliper with a hook or bungee cord. Do not let it hang by the rubber brake hose.
• ⚠️ Battery disconnect is not required for this front brake job.

📋 Before You Begin

• Park your Highlander on level ground.
• Shift to Park and apply the parking brake.
• Place wheel chocks behind the rear wheels.
• Open the hood and check the brake fluid reservoir level.
• If the reservoir is near the MAX line, use a clean turkey baster or fluid syringe to remove a small amount before compressing the caliper pistons.
• A caliper piston is the round part inside the brake caliper that pushes the brake pad against the rotor.
• No infotainment service mode or scan tool command is required for the front brakes on your Highlander.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

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

Step 2: Raise and Support the Front of the Vehicle

• Use a floor jack rated 3-ton minimum to lift the front of your Highlander 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.
• Use wheel chocks behind the rear wheels if not already installed.
• Lightly shake the vehicle to confirm it is stable before working.

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 side of the vehicle as an extra safety backup.

Step 4: Inspect the Brake Assembly

• Put on safety glasses and nitrile gloves.
• Look at the brake hose, caliper, rotor, and pad wear before taking anything apart.
• Use a flat-blade screwdriver to gently check that the caliper can slide slightly on its pins.
• If one pad is much thinner than the other, the slide pins may be sticking.

Step 5: Remove the Caliper Slide Pin Bolts

• Use a 14mm socket and 3/8-inch ratchet to remove the two caliper slide pin bolts.
• The slide pins are the small moving guide pins that let the caliper float evenly over the rotor.
• Hold the slide pin steady if it spins while loosening the bolt.

Step 6: Lift Off and Support the Caliper

• Use a flat-blade screwdriver to gently wiggle the caliper loose if needed.
• Lift the caliper off the bracket.
• Hang it from the strut spring using a brake caliper hanger hook.
• Do not stretch, twist, or kink the brake hose.

Step 7: Remove the Old Brake Pads

• Use your hands or a flat-blade screwdriver to slide the old brake pads out of the caliper bracket.
• Note the position of any wear indicator clips before removing them.
• The wear indicator is the small metal tab that makes noise when pads get low.

Step 8: Remove the Caliper Bracket

• Use a 17mm socket and 1/2-inch breaker bar to remove the two front caliper bracket bolts.
• Remove the caliper bracket and set it on a clean surface.
• These bolts are tight, so keep the socket straight to avoid rounding the bolt heads.

Step 9: Remove the Old Rotor

• Pull the rotor straight off the hub by hand.
• If it is stuck, thread two M8 x 1.25 bolts evenly into the rotor removal holes.
• Use a 3/8-inch ratchet to tighten each bolt a little at a time until the rotor pops loose.
• If needed, tap the rotor hat with a dead-blow hammer.
• Do not hit the wheel studs.

Step 10: Clean the Hub Face

• Use a wire brush to clean rust and debris from the wheel hub face.
• The hub face is the flat surface the rotor sits against.
• Use brake cleaner spray and a brake parts cleaning brush to clean the area.
• A clean hub prevents brake vibration.

Step 11: Install the New Rotor

• Clean both sides of the new rotor using brake cleaner spray.
• Slide the rotor onto the hub by hand.
• Install one lug nut backward by hand to hold the rotor flat while you work.

Step 12: Service the Caliper Bracket

• Use a flat-blade screwdriver to remove the old pad hardware clips from the caliper bracket.
• Use a wire brush to clean the areas under the clips.
• Install the new front brake hardware kit clips by hand.
• Apply a thin layer of high-temperature brake lubricant where the pad ears touch the clips.
• Do not put grease on the pad friction material or rotor surface.

Step 13: Check and Grease the Slide Pins

• Pull each slide pin out of the caliper bracket by hand.
• Wipe the pins clean with a shop towel.
• Apply disc brake caliper slide pin grease to each pin.
• Push the pins back into the bracket and make sure they move smoothly.

Step 14: Reinstall the Caliper Bracket

• Position the caliper bracket over the new rotor.
• Start both bracket bolts by hand to avoid cross-threading.
• Use a 17mm socket and 1/2-inch torque wrench to tighten the caliper bracket bolts.
• Torque to 145 Nm (107 ft-lbs)

Step 15: Compress the Caliper Pistons

• Place one old brake pad against the caliper pistons.
• Use a brake caliper piston compressor tool to slowly push the pistons fully back into the caliper.
• Watch the brake fluid reservoir while compressing the pistons.
• If fluid rises near the top, remove a small amount with a clean fluid syringe.
• Go slow to protect brake components.

Step 16: Install the New Brake Pads

• Slide the new inner and outer brake pads into the caliper bracket by hand.
• Make sure the pad ears sit correctly in the new hardware clips.
• Apply a thin layer of high-temperature brake lubricant to pad backing contact points only.
• Do not grease the front friction surface of the pads.

Step 17: Reinstall the Caliper

• Remove the brake caliper hanger hook and lower the caliper over the new pads.
• Start both slide pin bolts by hand.
• Use a 14mm socket and 3/8-inch torque wrench to tighten the slide pin bolts.
• Torque to 34 Nm (25 ft-lbs)

Step 18: Repeat on the Other Front Side

• Repeat Steps 4 through 17 on the other front brake assembly.
• Use the same tools and torque specs.
• Always replace front brake pads and rotors in pairs.

Step 19: Reinstall the Front Wheels

• Remove the temporary backward lug nut holding each rotor.
• Install the front wheels by hand.
• Use a 21mm lug nut socket and 3/8-inch ratchet to snug the lug nuts in a star pattern.

Step 20: 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 a 21mm lug nut socket and 1/2-inch torque wrench to tighten the lug nuts in a star pattern.
• Torque to 103 Nm (76 ft-lbs)

Step 21: Pump the Brake Pedal

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

✅ After Repair

• ✅ Check the brake fluid level and adjust it to the proper range if needed.
• ✅ Start the engine and press the brake pedal again. It should feel firm, not sink to the floor.
• ✅ Look around both front calipers for leaks or twisted brake hoses.
• ✅ Test drive slowly in a safe area before normal driving.
• ✅ Bed in the new pads if the pad manufacturer recommends it.
• ✅ A common bedding method is 8-10 moderate stops from about 30-35 mph, allowing cooling time between stops.
• ✅ Avoid hard panic stops for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after the first short drive.
