⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack by itself.
• ⚠️ Use jack stands before putting any part of your body near the wheel area.
• ⚠️ Brake dust can be harmful. Wear safety glasses and a dust mask, and do not blow dust with compressed air.
• ⚠️ Front brake calipers are heavy. Do not let the caliper hang by the rubber brake hose.
• ⚠️ Brake fluid can damage paint. Keep the master cylinder area clean and wipe spills immediately.
• ⚠️ No battery disconnect is required for this front brake job.

📋 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 stop the vehicle from rolling.
• 🧰 Loosen the front lug nuts slightly before lifting the vehicle.
• 🧴 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 piston.
• 📌 Do one side at a time so the other side stays assembled as a reference.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

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

Step 2: Lift and Support the Front

• Use a floor jack rated 2-ton minimum at the front center jacking point or the proper front side pinch weld area.
• Place jack stands rated 2-ton minimum under the front support points.
• Lower the vehicle gently onto the jack stands.
• Give the vehicle a small shake by hand to confirm it is stable.

Step 3: Remove the Front Wheel

• Use the 21mm lug nut socket and ratchet handle 3/8-inch drive to remove the lug nuts.
• Remove the wheel and place it flat under the side of the vehicle as an extra safety backup.

Step 4: Inspect the Brake Layout

• Look at the brake caliper, brake pads, caliper bracket, and rotor before taking anything apart.
• The caliper is the clamp-shaped part that squeezes the pads onto the rotor.
• The rotor is the round metal disc behind the wheel.
• Use safety glasses and a dust mask before cleaning around the brakes.

Step 5: Remove the Lower Caliper Slide Bolt

• Use a 14mm socket and ratchet handle 3/8-inch drive to remove the lower caliper slide bolt.
• If the slide pin spins, hold the pin flats carefully with a wrench if needed.
• A slide pin is the smooth pin the caliper moves on as the pads wear.

Step 6: Swing the Caliper Up

• Use a flat-blade screwdriver medium to gently pry the caliper upward if it is snug.
• Swing the caliper upward like a hinge.
• Use a bungee cord 18-inch to support the caliper from the strut spring.
• Do not stretch, twist, or hang the caliper by the brake hose.

Step 7: Remove the Old Brake Pads

• Pull the old inner and outer brake pads out of the caliper bracket by hand.
• If they are stuck, use a flat-blade screwdriver medium to gently work them free.
• Note the position of any wear indicator tab before removal.

Step 8: Remove the Caliper Bracket

• Use a 17mm socket and breaker bar 1/2-inch drive to remove the two caliper bracket bolts.
• Remove the caliper bracket and set it aside.
• These bolts are tight from the factory, so keep the socket fully seated.

Step 9: Remove the Old Rotor

• Pull the rotor straight off by hand.
• If the rotor is stuck, thread two M8 x 1.25 bolts evenly into the small threaded holes on the rotor hat.
• Use a ratchet handle 3/8-inch drive to tighten the bolts evenly a little at a time until the rotor pops loose.
• If needed, tap the rotor hat with a rubber mallet 16-ounce.
• Do not hammer the wheel studs.

Step 10: Clean the Hub Face

• Use a wire brush small 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 nozzle and a catch pan 2-quart to rinse away dust and rust flakes.
• A clean hub helps prevent pedal vibration.

Step 11: Install the New Rotor

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

Step 12: Service the Caliper Bracket Hardware

• Use a flat-blade screwdriver medium to remove the old pad hardware clips from the caliper bracket.
• Use a wire brush small to clean the bracket lands where the clips sit.
• Install the new clips from the front brake pad hardware kit by hand.
• Apply a very thin film of disc brake caliper slide pin grease to the pad contact points on the clips.
• Do not put grease on the pad friction material or rotor face.

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 lightly to each pin.
• Push the pins back in by hand and make sure they move smoothly.

Step 14: Reinstall the Caliper Bracket

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

Step 15: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use a C-clamp 6-inch or brake caliper piston compression tool (specialty) to slowly push the piston fully back into the caliper.
• Go slowly and watch the brake fluid level under the hood so it does not overflow.
• The piston is the round part that pushes the inner brake pad.

Step 16: Install the New Brake Pads

• Install the new inner and outer brake pads into the caliper bracket by hand.
• Make sure the pads slide easily in the hardware clips.
• If a pad has a wear indicator, match its position to the old pad layout.
• Do not force the pads into place.

Step 17: Lower the Caliper Over the Pads

• Remove the bungee cord 18-inch.
• Lower the caliper carefully over the new pads.
• If it will not fit, use the C-clamp 6-inch to compress the piston a little more.

Step 18: Reinstall the Caliper Slide Bolt

• Install the lower caliper slide bolt by hand first.
• Use a 14mm socket and torque wrench 3/8-inch drive to tighten the caliper slide bolt to Torque to 34 Nm (25 ft-lbs).

Step 19: Repeat on the Other Front Side

• Use the same tools and steps on the opposite front brake.
• Replace pads and rotors in pairs so braking stays even side-to-side.

Step 20: Reinstall the Wheels

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

Step 21: Lower and Torque the Wheels

• Use the floor jack rated 2-ton minimum to lift the vehicle slightly off the jack stands.
• Remove the jack stands rated 2-ton minimum.
• Lower the vehicle until the tires touch the ground.
• Use a 21mm lug nut socket and torque wrench 1/2-inch drive to tighten the lug nuts in a star pattern to Torque to 103 Nm (76 ft-lbs).

Step 22: Pump the Brake Pedal

• Before driving, press the brake pedal slowly 5-10 times until it feels firm.
• This moves the caliper pistons back into position against the new pads.
• Do not skip this step. The pedal may go low on the first press.

✅ After Repair

• ✅ Check the brake fluid level and top off with DOT 3 brake fluid if needed.
• ✅ Start your Highlander and press the brake pedal again. It should feel firm.
• ✅ Check around both front calipers for leaks.
• ✅ Test drive slowly in a safe area before normal driving.
• ✅ Bed in the new brakes with several gentle stops from about 30 mph to 5 mph, allowing short cooling time between stops.
• ✅ Avoid hard braking for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after 25-50 miles: Torque to 103 Nm (76 ft-lbs).
