🔧 Highlander - Front Brake Pad & Rotor Replacement

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

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

⚠️ Safety & Precautions

• ⚠️ Your Highlander is a hybrid, so do not open or service any orange high-voltage cables or hybrid components.
• ⚠️ Work on a cool vehicle. Brake parts can become very hot after driving.
• ⚠️ Always support the vehicle with jack stands. Never rely on a floor jack alone.
• ⚠️ Do not press the brake pedal while the caliper is removed.
• ⚠️ Brake dust can be harmful. Do not blow it with compressed air; use brake cleaner.
• ⚠️ Keep brake grease off the pad friction surface and rotor face.
• ⚠️ Battery disconnect is not normally required for front pad and rotor replacement, but keep the ignition fully OFF and key fob away from the vehicle.

📋 Before You Begin

• Park your Highlander on a level, solid surface.
• Shift to Park and apply the parking brake.
• Turn the ignition fully OFF and move the key fob at least 15 feet away from the vehicle.
• Place wheel chocks behind the rear wheels. Wheel chocks are blocks that stop the vehicle from rolling.
• Open the hood and check the brake fluid level. If it is near MAX, remove a small amount with a clean suction tool before compressing caliper pistons.
• Do one side at a time so the other side can be used as a reference.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Lug Nuts

• Use the 21mm lug nut socket and 1/2-inch breaker bar to loosen the front lug nuts about 1/2 turn while the tires are still on the ground.
• Do not remove the lug nuts yet.
• Loosen first, lift second.

Step 2: Lift and Support the Front of the Vehicle

• Use the floor jack at the front center jacking point to raise the front of your Highlander.
• Place jack stands under the front side support points.
• Slowly lower the vehicle onto the jack stands using the floor jack.
• Gently shake the vehicle by hand 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 vehicle as an extra safety backup.

Step 4: Remove the Brake Caliper

• Turn the steering wheel to give yourself more room on the side you are working on.
• Use the 14mm socket and 3/8-inch ratchet to remove the two brake caliper slide pin bolts.
• Slide the caliper off the rotor by hand.
• Use the bungee cord to hang the caliper from the suspension spring or strut area.
• Do not let the caliper hang by the rubber brake hose.

Step 5: Remove the Old Brake Pads and Hardware

• Use the flathead screwdriver to gently pry the old brake pads out of the caliper bracket.
• Remove the metal pad clips from the caliper bracket by hand or with the flathead screwdriver.
• These clips are called abutment clips; they let the pads slide smoothly.
• Compare the old pads to the new pads before throwing anything away.

Step 6: Remove the Caliper Bracket

• Use the 17mm socket and 1/2-inch breaker bar to remove the two caliper bracket bolts.
• Remove the caliper bracket from the steering knuckle.
• These bolts are tight, so use steady pressure.

Step 7: Remove the Old Rotor

• Pull the rotor straight off the wheel hub by hand.
• If the rotor is stuck, tap the rotor hat with the rubber mallet.
• The rotor hat is the raised center section of the rotor.
• Do not hit the wheel studs.

Step 8: Clean the Hub Surface

• Use the wire brush to clean rust and debris from the wheel hub face.
• Use brake cleaner spray and the catch pan to wash away dust and residue.
• A clean hub helps the new rotor sit flat and prevents brake vibration.

Step 9: 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 wheel hub by hand.
• Thread one lug nut on by hand using the 21mm lug nut socket to hold the rotor flat while you work.

Step 10: Prepare the Caliper Bracket

• Use the wire brush to clean the pad clip contact areas on the caliper bracket.
• Install the new brake hardware clips by hand.
• Apply a thin layer of disc brake grease to the areas where the pad ears touch the clips.
• Pad ears are the small tabs on each end of the brake pad backing plate.
• Do not put grease on the rotor or pad friction material.

Step 11: Reinstall the Caliper Bracket

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

Step 12: Compress the Caliper Pistons

• Place an old brake pad against the caliper pistons.
• Use the brake caliper piston compressor tool to slowly push the pistons fully back into the caliper.
• A caliper piston compressor tool pushes the pistons back evenly so the new thicker pads fit.
• Watch the brake fluid reservoir under the hood while compressing the pistons.
• If fluid gets close to overflowing, stop and remove a small amount safely.

Step 13: Install the New Brake Pads

• Install the new inner and outer brake pads into the caliper bracket by hand.
• Make sure the pads slide smoothly in the new hardware clips.
• If the pad set includes wear indicators, install them in the same position as the original pads.
• Pads should move freely, not jam.

Step 14: Reinstall the Brake Caliper

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

Step 15: Repeat on the Other Front Side

• Repeat Steps 4 through 14 on the opposite front wheel.
• Use the same tools and the same torque specifications.
• Always replace front pads and rotors in pairs.

Step 16: Reinstall the Front Wheels

• Remove the temporary lug nut holding each rotor with the 21mm lug nut socket.
• Install each wheel by hand.
• Thread all 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 17: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack to raise the vehicle slightly and remove the jack stands.
• Lower the vehicle until the tires touch the ground.
• Use the 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)
• Fully lower the vehicle and remove the floor jack.

Step 18: 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 adjust it to the proper range if needed.
• ✅ Start your Highlander and confirm the brake pedal remains firm.
• ✅ Look behind both front wheels for brake fluid leaks.
• ✅ Test the brakes at low speed in a safe area before normal driving.
• ✅ Bed in the new pads if the pad manufacturer recommends it. Bedding means making several controlled stops to transfer an even layer of pad material onto the rotor.
• ✅ Avoid hard braking for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after 25-50 miles using the 21mm lug nut socket and 1/2-inch torque wrench.
