🔧 Highlander - Front Brake Pads and Rotor Replacement

This repair replaces the front brake pads and both front rotors on your Highlander. Replacing both sides together helps maintain even braking and prevents pulling or vibration.

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

⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and support the Highlander with jack stands—never rely on the floor jack alone.
• ⚠️ Wear safety glasses and nitrile gloves because brake dust and cleaner can irritate your eyes and skin.
• ⚠️ Do not inhale brake dust or blow it away with compressed air. Wet it with brake cleaner.
• ⚠️ Do not press the brake pedal while either caliper is removed.
• ⚠️ Never allow a caliper to hang from its flexible brake hose.
• ⚠️ Brake fluid damages paint. Clean spills immediately with water.
• ⚠️ Battery disconnection is not required for this repair.

📋 Before You Begin

• 🅿️ Park on level pavement, shift into Park, apply the parking brake, and switch off the ignition.
• 🛞 Place wheel chocks tightly behind both rear tires.
• 🌡️ Allow the brakes to cool completely before touching them.
• 📱 Take a photograph of the original pad clips and hardware before disassembly.
• 🔍 Check the brake-fluid reservoir. If it is near the MAX line, use the turkey baster to remove a small amount into the drain pan so it will not overflow when the pistons are compressed.
• 🧼 Keep grease and brake fluid completely off all pad and rotor friction surfaces.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Use the 21mm deep socket and breaker bar to loosen each front wheel nut about one-half turn.
• Do not remove the wheel nuts while the tires are still supporting the Highlander.

Step 2: Raise and Support the Front

• Use the floor jack at the front-center lifting point on the front suspension crossmember.
• Position both jack stands under the reinforced side support points behind the front wheels.
• Lower the Highlander slowly onto the jack stands, then gently push the body to verify it is stable.
• Keep the floor jack lightly positioned under the front-center point as secondary support.

Step 3: Remove Both Front Wheels

• Use the 21mm deep socket and ratchet to remove the wheel nuts.
• Remove both wheels and slide them beneath the side structure as additional protection.

Step 4: Remove the First Brake Caliper

• Turn the steering wheel to provide easier access to the caliper bolts.
• Use the 14mm socket and ratchet to remove the upper and lower caliper slide-pin bolts.
• If a slide pin rotates, hold its flat section with the 17mm combination wrench while loosening the bolt.
• Lift the caliper away from the pads and suspend it with the caliper hanger hook.
• A slide pin is the smooth pin that allows the caliper to move sideways as the brakes operate.
• Do not twist, stretch, or place weight on the brake hose.

Step 5: Remove the Old Pads and Hardware

• Use the flat-blade screwdriver carefully to lift the inner and outer pads from the caliper bracket.
• Use the flat-blade screwdriver to remove the stainless pad-support clips.
• Note the position of wear indicators and any pad shims so the new pieces face the same direction.
• Compare the inner and outer pads. Strongly uneven wear may indicate a seized slide pin or caliper.

Step 6: Remove the Caliper Bracket

• Use the 19mm socket and breaker bar to remove the two caliper-bracket bolts behind the steering knuckle.
• Hold the bracket securely as the final bolt is removed.
• Do not confuse these large bracket bolts with the smaller 14mm slide-pin bolts.

Step 7: Remove the Old Rotor

• Pull the rotor straight off the wheel hub.
• If rust holds it in place, use the rubber mallet to strike the rotor hat between the wheel studs.
• If necessary, thread the two M8 x 1.25 x 30mm forcing bolts evenly into the rotor’s threaded removal holes using the appropriate 13mm socket supplied for the bolt heads.
• Tighten each forcing bolt a little at a time until the rotor releases. Do not strike the wheel studs.

Step 8: Clean and Inspect the Hub

• Place the drain pan below the work area.
• Use brake cleaner and the wire hub-cleaning brush to remove rust from the hub face and center pilot.
• Use the small nylon detailing brush around the wheel studs.
• Wipe the hub clean and confirm there are no raised rust flakes. A dirty hub can make the new rotor wobble.
• Clean hub surfaces prevent pedal pulsation.

Step 9: Prepare and Install the New Rotor

• Use brake cleaner and a clean lint-free towel to remove protective oil from both rotor faces.
• Slide the new rotor fully onto the hub without touching its friction surfaces with greasy gloves.
• Temporarily install two wheel nuts by hand, flat side toward the rotor, to hold it firmly against the hub.

Step 10: Service the Caliper Bracket

• Use brake cleaner and the small nylon detailing brush to clean the pad-support areas on the bracket.
• Remove each slide pin by hand, one at a time, so their original positions are not mixed.
• Wipe the pins clean and inspect them for rust, pitting, or binding.
• Apply a thin layer of silicone-based brake lubricant to each slide pin, then reinstall it through its rubber boot.
• Replace any torn or swollen slide-pin boot. Each pin must move smoothly by hand.
• Install the new stainless pad hardware by hand. It must sit completely flat.

Step 11: Reinstall the Caliper Bracket

• Position the bracket over the rotor and start both 19mm-headed bolts by hand to prevent cross-threading.
• Use the 19mm socket and 1/2-inch torque wrench to tighten both bracket bolts to 107 Nm (79 ft-lbs).

Step 12: Compress the Caliper Pistons

• Place an old brake pad across both caliper pistons.
• Use the brake caliper piston compression tool to push both pistons inward slowly and evenly.
• Watch the brake-fluid reservoir during compression and remove excess fluid with the turkey baster if it approaches the rim.
• If either piston will not retract smoothly, stop. The caliper or brake hose may require professional diagnosis.
• Confirm the rubber piston boots are not twisted or pinched.

Step 13: Install the New Brake Pads

• Apply a very thin layer of high-temperature brake pad lubricant only where the pad ears contact the stainless hardware.
• Apply a thin layer to metal shim contact points if required by the pad manufacturer.
• Do not place lubricant on the pad material or rotor.
• Install the inner and outer pads by hand in the same orientation as the originals.
• Confirm both pads slide freely in the bracket without excessive looseness.

Step 14: Reinstall the Caliper

• Lower the caliper over the new pads without twisting the brake hose.
• Start both slide-pin bolts by hand.
• If a pin turns, hold its flat section with the 17mm combination wrench.
• Use the 14mm socket and 3/8-inch torque wrench to tighten both slide-pin bolts to 34 Nm (25 ft-lbs).
• Remove the two temporary wheel nuts using the 21mm deep socket.

Step 15: Repeat on the Other Side

• Repeat Steps 4 through 14 on the opposite front brake assembly using the same listed tools.
• Replace both rotors and all four front pads even if one side appears less worn.

Step 16: Reinstall the Wheels

• Install each wheel and start every wheel nut by hand.
• Use the 21mm deep socket and ratchet to snug the nuts in a crisscross pattern.
• Use the floor jack to raise the Highlander, remove both jack stands, and lower it until the tires contact the ground.
• Use the 21mm deep socket and 1/2-inch torque wrench to tighten the wheel nuts in a crisscross pattern to 103 Nm (76 ft-lbs).

Step 17: Restore Brake-Pedal Pressure

• Before moving the Highlander, press and release the brake pedal slowly several times until it becomes firm.
• Use the brake-fluid reservoir markings to verify the fluid is between MIN and MAX.
• Add only fresh DOT 3 brake fluid if needed. Do not overfill the reservoir.

✅ After Repair

• ✅ Start the engine and hold firm pressure on the brake pedal for 30 seconds. The pedal should remain firm and should not sink toward the floor.
• ✅ Inspect both front calipers and hoses for damage, fluid leakage, or twisted hoses.
• ✅ Test the brakes at walking speed in a clear area before entering traffic.
• ✅ Bed the pads using the pad manufacturer’s procedure. If none is supplied, make 6-8 moderate stops from approximately 50 km/h to 10 km/h without activating ABS, allowing brief cooling between stops.
• ✅ Drive for 10 minutes without heavy braking to cool the new brakes. Do not stop with the pedal held hard while the brakes are extremely hot.
• ✅ Avoid panic stops and heavy braking for the first 300-500 km unless required for safety.
• ✅ Recheck wheel-nut torque to 103 Nm (76 ft-lbs) after approximately 80-160 km.
• ✅ Stop driving if the pedal remains soft, the Highlander pulls sharply, or brake fluid is leaking.
