🔧 Highlander - Front Brake Pads & Rotors Replacement

This job replaces the front brake pads and rotors on your Highlander to restore braking power and prevent vibration or noise. You’ll lift the front, remove the wheels, swap pads and rotors, then torque everything correctly.

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

⚠️ Safety & Precautions

• 🛑 Always support the vehicle with jack stands; never rely only on a jack.
• 🛑 Work on a flat, solid surface; avoid dirt or slopes.
• 🛑 Wear safety glasses and gloves; brake dust and cleaner are irritating.
• 🛑 Do one side at a time so you can look at the other side as a reference.
• 🛑 Do not press the brake pedal with a caliper removed; it can push the piston out.
• 🛑 Brakes can be very hot if you just drove; let them cool first.
• 🛑 Keep brake cleaner, oil, and grease off the rotor and pad friction surfaces.
• 🛑 Battery disconnection is not required for front brake work on your Highlander.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the front and remove the wheels

• Place the floor jack (3-ton) under the front center jacking point (behind the front bumper crossmember) and raise the front until both front wheels are off the ground.
• Position jack stands (3-ton) under the factory pinch weld or frame points on both sides and slowly lower the vehicle onto them.
• Use the 21mm socket and ratchet or lug wrench to remove all front wheel lug nuts and take off both front wheels.
• Give the car a small push; it should feel solid.

Step 2: Inspect the caliper area

• Turn the steering wheel to the left to better access the right front brake, and to the right to access the left front brake as you work.
• Identify the brake caliper (the part that squeezes the pads), the caliper bracket behind it, and the rotor (the disc).
• Check brake hoses for cracks or leaks while you are here.

Step 3: Remove the caliper (outer part)

• On the back of the caliper, locate the two slide pin bolts (upper and lower). On your Highlander these are typically 17mm.
• Use a 17mm socket and 3/8" ratchet to loosen and remove both caliper slide pin bolts.
• Gently pry the caliper away from the pads using a flathead screwdriver if needed, then lift the caliper off the bracket.
• Hang the caliper from the suspension spring using a caliper hanger hook or bungee cord so the rubber brake hose is not supporting the weight.
• Never let the caliper dangle by the hose.

Step 4: Remove the old brake pads and hardware

• Slide the inner and outer brake pads out of the caliper bracket by hand.
• Note how the pad wear indicator (small metal tab) is positioned so you can install the new one the same way.
• Remove the metal pad support clips (hardware) from the caliper bracket using a flathead screwdriver if they are tight.
• Use a wire brush to clean the surfaces of the caliper bracket where the clips sit. Do not grind into the metal; just remove rust and dirt.
• Clean hardware surfaces help pads move smoothly.

Step 5: Remove the caliper bracket

• Locate the two large caliper bracket bolts on the back of the steering knuckle. These are typically 19mm on your Highlander.
• Use a 19mm socket, 1/2" ratchet, or breaker bar to loosen and remove both bracket bolts.
• Remove the entire caliper bracket and set it aside on a clean surface.
• Crack bolts loose while supporting bracket with other hand.

Step 6: Remove the old rotor

• If the rotor slides off easily, pull it straight off the hub.
• If it is stuck due to rust, spray around the hub center with brake cleaner, then gently tap the rotor hat (flat face between studs) with a rubber mallet or the side of a hammer (do not hit the studs).
• Your rotor may have threaded holes for “service bolts.” If needed, thread two M8 x 1.25 bolts into these holes and tighten them evenly with an appropriate socket to push the rotor off the hub.
• Once loose, remove the rotor completely.

Step 7: Clean and prepare the hub and new rotor

• Use a wire brush to clean the wheel hub face until rust and loose scale are removed; this helps prevent rotor wobble and brake pulsation.
• Wipe the hub with a shop rag and a little brake cleaner.
• Lightly apply a thin smear of anti-seize compound to the hub face and around the center hub ring (very thin film).
• Spray both sides of the new rotor with brake cleaner to remove oil coating, then wipe dry with a clean rag.
• Clean rotors stop better and prevent pad glazing.

Step 8: Install the new rotor

• Slide the new rotor onto the hub, aligning the holes with the wheel studs.
• Temporarily install one or two lug nuts backward (flat side to rotor) by hand using the 21mm socket to hold the rotor snug against the hub while you work.

Step 9: Reinstall the caliper bracket

• Position the caliper bracket over the new rotor and align it with the mounting holes in the steering knuckle.
• Install the caliper bracket bolts by hand first to avoid cross-threading.
• Use a 19mm socket and 1/2" ratchet to snug both bolts.
• Then torque both caliper bracket bolts to 107 Nm (79 ft-lbs) using the torque wrench.
• Always torque suspension and brake bolts by spec.

Step 10: Install new pad hardware and prepare pads

• Clip the new metal pad hardware (support clips) into the cleaned caliper bracket by hand. Make sure they sit fully and evenly.
• Apply a very thin coat of high-temperature brake lubricant to the areas of the clips where the pad backing will slide. Do not get grease on the rotor or pad friction surface.
• Apply a small amount of brake lubricant to the backs of the pads where they contact the caliper and shims, if recommended by the pad manufacturer.
• If your pads include a wear indicator tab, install the inner pad so the tab is in the same location as the original (usually on the inner pad, lower side).

Step 11: Compress the caliper piston

• Before compressing, open the hood and check the brake fluid level in the master cylinder. If it is very full, you may need to remove a small amount with a clean syringe or turkey baster to prevent overflow.
• Place the old inner pad against the caliper piston face.
• Use a C-clamp or disc brake piston tool (specialty) between the caliper housing and the old pad to slowly push the piston back into the caliper until it bottoms out.
• Go slowly to avoid damaging the piston seal. Stop if you feel sudden hard resistance and check alignment.
• Slow steady pressure protects seals inside the caliper.

Step 12: Install new pads and caliper

• Install the new inner and outer pads into the caliper bracket, sliding their ears into the new hardware clips. They should move freely but not be loose.
• Lower the caliper over the new pads and into place on the bracket.
• Align the caliper slide pin bolt holes.
• Apply a small amount of high-temperature brake lubricant to the smooth part of the slide pins if they look dry, then insert them.
• Thread the slide pin bolts by hand first, then tighten with a 17mm socket and 3/8" ratchet.
• Torque the caliper slide pin bolts to 46 Nm (34 ft-lbs) using the torque wrench.

Step 13: Repeat on the other side

• Repeat Steps 3–12 on the other front wheel.
• Try to match the cleanliness and lubrication you did on the first side.

Step 14: Reinstall wheels and lower the vehicle

• Remove the temporary lug nuts holding the rotor using the 21mm socket.
• Mount the wheel on the hub and install all lug nuts by hand.
• Snug the lug nuts with the 21mm socket and ratchet in a star pattern while the vehicle is still on stands.
• Raise the vehicle slightly with the floor jack, remove the jack stands, then carefully lower the vehicle to the ground.
• Torque the lug nuts in a star pattern to 103 Nm (76 ft-lbs) using the torque wrench and 21mm socket.

Step 15: Pump the brakes and check fluid

• Before driving, sit in the driver’s seat and slowly press the brake pedal 10–15 times until it becomes firm. This seats the pads against the rotors.
• Check the brake fluid level in the reservoir and top up if needed using the correct brake fluid type listed on the cap (usually DOT 3 or DOT 4). Do not overfill.
• Check around both front calipers and brake hoses for any signs of leaks or issues.

✅ After Repair

• 🚗 Test-drive in a safe, low-traffic area at low speeds (20–40 km/h), gently braking several times to ensure the pedal feels firm and the vehicle stops straight.
• 🚗 Listen for unusual noises like grinding, knocking, or loud squealing; a light, temporary squeak can be normal during pad bedding.
• 🚗 After the test drive, check that the front wheels are not excessively hot compared to each other (warm is normal; one wheel much hotter can indicate dragging brakes).
• 🚗 Follow a gentle pad “bed-in” process: make 5–10 medium stops from ~50–60 km/h down to 10–20 km/h, allowing some cool-down time between stops. Avoid hard emergency-style braking for the first 300–500 km unless necessary.
