⚠️ Safety & Precautions

• 🛑 Work on a flat, solid surface only. Never work under a vehicle supported only by a jack.
• 🛑 Use jack stands. A jack lifts the vehicle; jack stands safely hold it up.
• 🛑 Wear safety glasses and gloves. Brake dust and rust can irritate your skin and eyes.
• 🛑 Do not press the brake pedal while the caliper is removed.
• 🛑 Do one side at a time so the other side stays assembled as a reference.
• 🛑 Brake fluid may rise when pushing caliper pistons back. Check the reservoir and remove excess with a clean fluid syringe if needed.
• 🛑 Battery disconnect is not required for this front brake repair.

📋 Before You Begin

• 🅿️ Park your Highlander on level ground and shift to Park.
• 🅿️ Set the parking brake and place wheel chocks behind the rear wheels.
• 🧰 Open the hood and locate the brake fluid reservoir. This is the small plastic tank near the driver side rear of the engine bay.
• 🧰 Make sure the front brake parts match both sides before disassembly.
• 🧰 Brake lubricant is special high-temperature grease used only on sliding contact points, not on pad friction material or rotor surfaces.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Lug Nuts

• Use the 21mm lug nut socket and breaker bar 1/2-inch drive to loosen each front lug nut about half a turn.
• Do not remove the lug nuts yet.
• Loosen wheels before lifting.

Step 2: Lift and Support the Front of the Vehicle

• Use the 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.
• Slowly lower the vehicle onto the jack stands.
• Gently shake the vehicle by hand to make sure it is stable before removing wheels.

Step 3: Remove the Front Wheels

• Use the 21mm lug nut socket and ratchet handle 3/8-inch drive 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

• Look at how the brake pads, clips, caliper, and rotor are installed before taking anything apart.
• The caliper is the clamp-shaped part that squeezes the brake pads against the rotor.
• The rotor is the large round metal disc behind the wheel.
• Take a picture with your phone for reference.

Step 5: Remove the Caliper Slide Pin Bolts

• Use the 14mm socket and ratchet handle 3/8-inch drive to remove the two caliper slide pin bolts on the back of the caliper.
• Slide pins allow the caliper to move smoothly as the brakes apply and release.
• Support the caliper with a bungee cord 24-inch from the strut spring or suspension area.
• Do not let the caliper hang by the rubber brake hose.

Step 6: Remove the Old Brake Pads

• Use a flat-head screwdriver medium to gently pry the old brake pads out of the caliper bracket.
• Remove the old pad hardware clips by hand or with the flat-head screwdriver medium.
• Pay attention to pad orientation and the small wear indicator tab location.

Step 7: Remove the Caliper Bracket

• Use the 17mm socket and breaker bar 1/2-inch drive to remove the two caliper bracket bolts.
• Remove the caliper bracket from the steering knuckle.
• The caliper bracket is the heavy metal carrier that holds the pads in place.

Step 8: Remove the Old Rotor

• Pull the rotor straight off the hub by hand.
• If stuck from rust, tap the rotor hat with the rubber mallet.
• Do not strike the wheel studs.
• If the rotor still sticks, apply brake cleaner spray around the hub area and continue tapping with the rubber mallet.

Step 9: Clean the Hub Surface

• Use the wire brush to clean rust and scale from the wheel hub face.
• The hub face must be smooth so the new rotor sits flat.
• Use brake cleaner spray to rinse away debris.
• A clean hub prevents vibration.

Step 10: Install the New Rotor

• Clean both sides of the new rotor with brake cleaner spray to remove protective oil.
• Slide the new rotor onto the hub by hand.
• Install one lug nut finger-tight using the 21mm lug nut socket to hold the rotor flat while you work.

Step 11: Clean and Prepare the Caliper Bracket

• Use the brake parts cleaning brush and wire brush to clean the pad contact areas on the caliper bracket.
• Install the new brake pad hardware clips by hand.
• Apply a thin layer of brake lubricant to the pad contact points on the hardware clips.
• Do not put lubricant on the rotor or the pad friction surface.

Step 12: Reinstall the Caliper Bracket

• Position the caliper bracket over the rotor.
• Start both bracket bolts by hand to avoid cross-threading.
• Use the 17mm socket and torque wrench 1/2-inch drive to tighten the caliper bracket bolts.
• Torque to 107 Nm (79 ft-lbs)

Step 13: Compress the Caliper Pistons

• Place one old brake pad against the caliper pistons.
• Use the brake caliper piston compressor tool (specialty) to slowly push the pistons fully back into the caliper.
• Go slowly and check the brake fluid reservoir under the hood while compressing.
• If fluid gets close to overflowing, remove a small amount with a clean fluid syringe.

Step 14: Install the New Brake Pads

• Apply a thin layer of brake lubricant to the pad backing plate contact points only.
• Slide the new inner and outer brake pads into the caliper bracket by hand.
• Make sure the friction material faces the rotor.
• The pads should move smoothly in the hardware clips without forcing them.

Step 15: Reinstall the Caliper

• Remove the bungee cord 24-inch and lower the caliper over the new pads.
• Start both caliper slide pin bolts by hand.
• Use the 14mm socket and torque wrench 3/8-inch drive to tighten the slide pin bolts.
• Torque to 34 Nm (25 ft-lbs)

Step 16: Repeat on the Other Front Side

• Repeat Steps 5 through 15 on the other front wheel.
• Use the same tools and same torque values.
• Compare the second side to the first side if something looks confusing.

Step 17: Reinstall the Front Wheels

• Remove the temporary lug nut holding each rotor using the 21mm lug nut socket.
• Install each wheel by hand.
• Thread all lug nuts by hand first to avoid damaging the studs.
• Use the 21mm lug nut socket and ratchet handle 3/8-inch drive to snug the lug nuts in a star pattern.

Step 18: 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 fully to the ground.
• Use the 21mm lug nut socket and torque wrench 1/2-inch drive to tighten the lug nuts in a star pattern.
• Torque to 103 Nm (76 ft-lbs)

Step 19: 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 into position against the new pads.
• Do not drive until the pedal feels firm.

✅ After Repair

• ✅ Check 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 and normal.
• ✅ Look behind both front wheels for leaks or loose parts.
• ✅ Perform a slow test drive in a safe area before normal driving.
• ✅ Bed in the new brakes: make 8-10 moderate stops from about 30-40 mph, allowing a little cooling time between stops.
• ✅ Avoid hard emergency-style braking for the first 200 miles unless necessary.
• ✅ Recheck lug nut torque after 25-50 miles using the 21mm lug nut socket and torque wrench 1/2-inch drive.
