⚠️ Safety & Precautions

• ⚠️ Work on a cool vehicle. Brake parts can get very hot after driving.
• ⚠️ Support your Highlander with jack stands before working under or around the wheels. Never rely on a jack alone.
• ⚠️ Do not press the brake pedal while the caliper is removed.
• ⚠️ Brake dust can be harmful. Use brake cleaner, not compressed air, to clean brake parts.
• ⚠️ Battery disconnect is not required for this front brake pad replacement.

📋 Before You Begin

• Park your Highlander on level ground.
• Shift to Park and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Open the hood and locate the brake fluid reservoir. If it is filled to the very top, remove a small amount with a clean suction tool before pushing the caliper pistons back.
• Front brake service on your Highlander does not require an infotainment menu, EPB service mode, scan tool, or battery disconnect.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Put on safety glasses and nitrile gloves.
• 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 tires touch ground.

Step 2: Raise 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 support points.
• Slowly lower the vehicle onto the jack stands.
• Gently shake the vehicle by hand to confirm it is stable before removing 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 side of the vehicle as an added safety backup.

Step 4: Remove the Brake Caliper

• Turn the steering wheel to give yourself better access to the caliper you are working on.
• Use the 14mm socket and 3/8-inch ratchet to remove the lower and upper caliper slide bolts.
• If the slide pin spins, hold it with the 17mm wrench while loosening the bolt with the 14mm socket.
• Lift the caliper off the bracket.
• Do not let the caliper hang by the rubber brake hose. Rest it carefully on the suspension or support it securely.

Step 5: Remove the Old Brake Pads

• Use the flat-blade screwdriver to gently pry the old inner and outer brake pads out of the caliper bracket.
• Note the position of any wear indicator clip. The wear indicator is a small metal tab that makes noise when the pad is worn out.
• Remove the old pad hardware clips from the bracket by hand or with the flat-blade screwdriver.

Step 6: Clean the Caliper Bracket

• Place the catch pan under the brake area.
• Use brake cleaner spray to clean the pad contact areas on the caliper bracket.
• Use the wire brush to remove rust or buildup where the hardware clips sit.
• Do not breathe brake dust or blow it with air.

Step 7: Install New Brake Hardware

• Snap the new front brake pad hardware kit clips into the caliper bracket by hand.
• Make sure each clip sits flat and fully seated.
• Apply a very thin layer of brake caliper slide pin grease to the pad ears where they touch the hardware clips.
• Do not get grease on the brake pad friction surface or rotor.

Step 8: Compress the Caliper Piston

• Check the brake fluid reservoir under the hood. Fluid level may rise as the piston is pushed back.
• Place an old brake pad against the caliper piston.
• Use the disc brake pad spreader tool to slowly push the caliper piston fully back into the caliper.
• Move slowly so brake fluid does not overflow from the reservoir.

Step 9: Install the New Front Brake Pads

• Slide the new front brake pad set into the caliper bracket by hand.
• Install the pad with the wear indicator in the same general position as the original pad.
• The pads should slide smoothly in the new hardware. If they bind, remove them and recheck the clip seating.

Step 10: Reinstall the Brake Caliper

• Carefully lower the caliper over the new pads.
• Install the upper and lower caliper slide bolts by hand first to avoid cross-threading.
• Use the 14mm socket, 17mm wrench, and torque wrench rated to 100 ft-lbs to tighten the caliper slide bolts.
• Torque to 34 Nm (25 ft-lbs)

Step 11: Repeat on the Other Side

• Repeat Steps 4 through 10 on the opposite front brake.
• Always replace front brake pads in pairs.

Step 12: Reinstall the Front Wheels

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

Step 13: Lower and Torque the Wheels

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

Step 14: Pump the Brake Pedal

• Before driving, press the brake pedal slowly several times until it feels firm.
• This moves the caliper pistons back out against the new pads.
• If the pedal stays soft or sinks, do not drive until the brake system is inspected.

✅ After Repair

• Check the brake fluid level and make sure it is between the MIN and MAX marks.
• Start your Highlander and press the brake pedal again. It should feel firm.
• Test the brakes at very low speed in a safe area before normal driving.
• Bed in the new pads by making several gentle stops from moderate speed. Avoid hard braking for the first 100-200 miles unless needed for safety.
• After a short test drive, check for scraping noises, burning smells, or fluid leaks.
• Recheck lug nut torque after the first drive.
