🔧 Highlander - Front Brake Pad Replacement

Replacing the front brake pads involves lifting your Highlander, removing both front wheels, retracting the caliper pistons, and installing new pads and hardware. Replace the pads on both front wheels so braking remains balanced.

Difficulty Level: Beginner | Estimated Time: 1–1.5 hours

⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and support your Highlander with jack stands. Never work beneath a vehicle supported only by a jack.
• 🛑 Do not press the brake pedal while either caliper is removed.
• 🌡️ Allow the brakes to cool completely before starting.
• 🧤 Brake dust can be harmful. Wear gloves and safety glasses, and never blow dust away with compressed air.
• 🔋 Battery disconnection is not required for this front brake repair.
• 🚫 Keep grease and brake cleaner away from pad friction material and rotor braking surfaces.

📋 Before You Begin

• 📍 Park your Highlander on level pavement. Shift into Park, apply the parking brake, and switch off the ignition.
• 🧱 Place SUV-rated wheel chocks firmly in front of and behind a rear tire.
• 📖 Confirm the replacement pads match the original pad shape before taking both sides apart.
• 🔍 Check the brake-fluid reservoir. If the fluid is near the MAX line, use a brake fluid syringe to remove a small amount before compressing the pistons.
• 📱 No infotainment menu, electronic parking-brake service mode, scan tool, coding, or battery registration is required for the front brakes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Put on ANSI Z87.1 safety glasses and nitrile mechanic gloves.
• With your Highlander still on the ground, use a 21mm deep socket and 1/2-inch-drive breaker bar to loosen each front wheel nut about one-half turn.
• Do not remove the wheel nuts yet.

Step 2: Raise and Support the Front

• Use the 2-ton floor jack at the designated front lifting point shown in the owner’s manual.
• Place 2-ton jack stands beneath the designated reinforced side support points.
• Lower your Highlander gently onto the stands. Give the body a careful push to confirm it is stable.
• Keep the floor jack lightly touching the lift point.

Step 3: Remove Both Front Wheels

• Use the 21mm deep socket and 1/2-inch-drive breaker bar to remove the loosened wheel nuts.
• Lift off both wheels and place them flat away from the work area.
• Complete one brake assembly at a time. The untouched side provides a useful reference.

Step 4: Inspect the Brake Assembly

• Turn the steering wheel so the caliper is easier to reach.
• The caliper is the metal housing that squeezes the pads against the rotor.
• Use a soft-bristle brake cleaning brush and non-chlorinated brake cleaner to remove loose dust. Catch residue with lint-free shop towels.
• Inspect the rotor for deep grooves, heat cracks, heavy rust, or blue discoloration. A damaged or undersized rotor requires measurement and possible replacement before installing pads.
• Inspect the flexible brake hose for cracking, wetness, or swelling. Stop if leakage is present.

Step 5: Remove the Caliper

• Use a 14mm socket and 3/8-inch-drive ratchet to remove the upper and lower caliper slide-pin bolts.
• If a slide pin turns with the bolt, hold its flat section with the appropriately sized open-end wrench before loosening further. Do not grip the smooth sealing surface.
• Lift the caliper away from the bracket without pulling or twisting the brake hose.
• Support the caliper with a 50-pound caliper hanger. Never let it hang from the hose.
• Do not remove the caliper mounting bracket.

Step 6: Remove the Old Pads and Hardware

• Use a flat-blade screwdriver with a 6-inch shaft to carefully lift the inner and outer pads from the bracket.
• Remove the stainless pad-support clips with the flat-blade screwdriver.
• Note the positions of wear indicators, shims, and springs before removal.
• Compare the old and new pads. Uneven wear may indicate a sticking slide pin or piston that must be corrected before reassembly.

Step 7: Retract the Caliper Pistons

• Check the brake-fluid reservoir before retracting the pistons. Use the brake fluid syringe if the level approaches MAX.
• Place an old brake pad across the caliper pistons.
• Use the disc brake piston compressor to push the pistons back slowly and evenly until fully seated.
• Watch the reservoir while compressing. Do not allow brake fluid to overflow.
• Stop if either piston binds, tilts, or requires excessive force. This indicates a caliper problem.

Step 8: Inspect the Slide Pins and Boots

• Move both slide pins by hand. They should travel smoothly without binding.
• Inspect the rubber boots for tears and confirm each boot is seated in its grooves.
• If a pin is dry, remove it by hand, wipe it with a lint-free shop towel, and apply a thin coat of high-temperature silicone brake lubricant.
• Do not use petroleum grease because it can damage the rubber boots.

Step 9: Install New Hardware and Pads

• Use the flat-blade screwdriver with a 6-inch shaft to seat the new pad-support clips in the same positions as the originals.
• Apply a very thin film of high-temperature silicone brake lubricant only where the pad tabs contact the support clips.
• Install the inner and outer pads in the correct positions. Match the original wear-indicator orientation.
• Keep lubricant off the pad friction surfaces and rotor.
• Confirm each pad slides freely in the bracket without excessive looseness.

Step 10: Reinstall the Caliper

• Lower the caliper over the new pads by hand. Do not force it or twist the brake hose.
• Start both slide-pin bolts by hand to prevent crossed threads.
• Use the 14mm socket and 3/8-inch-drive torque wrench to tighten both slide-pin bolts to 34 Nm (25 ft-lbs).
• Confirm the hose follows its natural curve and does not touch the wheel or suspension.

Step 11: Repeat on the Other Side

• Use the same tools and procedure to replace the pads and hardware on the opposite front wheel.
• Verify both calipers are bolted securely and both brake hoses are correctly positioned.

Step 12: Reinstall the Wheels

• Place each wheel onto its hub and install the wheel nuts by hand.
• Use the 21mm deep socket and 1/2-inch-drive torque wrench to snug the nuts in a crossing pattern while the wheels are raised.
• Use the 2-ton floor jack to raise your Highlander slightly, remove the 2-ton jack stands, and lower it to the ground.
• Use the 21mm deep socket and 1/2-inch-drive torque wrench to tighten the wheel nuts in a crossing pattern to 103 Nm (76 ft-lbs).

Step 13: Restore Brake Pedal Pressure

• Before starting the engine, slowly press and release the brake pedal several times until it feels firm.
• Do not move your Highlander if the pedal remains soft or sinks toward the floor.
• Check the brake-fluid reservoir and adjust it to the MAX line with fresh DOT 3 brake fluid only if necessary.
• Use lint-free shop towels to wipe away any spilled fluid immediately.

✅ After Repair

• ✅ Start the engine while holding the brake pedal. Confirm the pedal remains firm and no brake warning light stays illuminated.
• 🔍 Inspect both front calipers and the brake-fluid reservoir for leakage.
• 🚗 Test the brakes at walking speed in a clear, private area before entering traffic.
• 🛞 Recheck the wheel-nut torque at 103 Nm (76 ft-lbs) after approximately 80–160 km.
• 📘 Follow the brake-pad manufacturer’s bedding procedure. Bedding gradually transfers pad material to the rotors for smooth, consistent braking.
• 🌡️ Avoid repeated emergency stops during the first 300 km unless needed for safety.
