🔧 Highlander - Front Brake Pads & Rotor Replacement

On your Highlander, the front brake pads clamp the rotors to slow the SUV down. When pads wear thin or rotors get grooved/pulsate, replacing pads and rotors together restores smooth, strong braking.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Work on flat, solid ground and chock the rear wheels.
• ⚠️ Support the Highlander with jack stands; never rely on a floor jack alone.
• ⚠️ Brake dust is hazardous—use brake cleaner, not compressed air.
• ⚠️ Do not let the brake caliper hang by the hose; support it with a hook/strap.
• ⚠️ Keep brake fluid off paint; it can damage the finish.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Loosen the front lug nuts slightly before lifting the Highlander.
• Pop the hood and check the brake fluid level; it may rise when you push the pistons back.
• Take a photo of pad/clip layout first.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use a 21mm socket and breaker bar to loosen the front lug nuts 1/2 turn.
• Lift the front with a floor jack (rated 3-ton minimum) at the front center jack point.
• Place jack stands (rated 3-ton minimum, pair) under the front pinch weld/side support points and lower onto stands.
• Remove the wheels using a 21mm socket.

Step 2: Remove the brake caliper

• Turn the steering wheel to give yourself room (left for right side, right for left side).
• Remove the two caliper slide pin bolts using a 14mm socket.
• Lift the caliper off the bracket and support it with a bungee cord or caliper hook. (A caliper is the part that squeezes the pads onto the rotor.)

Step 3: Remove pads and hardware

• Slide the old pads out by hand; use a flat trim tool gently if they’re stuck.
• Remove the pad clips/shims from the bracket using a flat trim tool.
• Clean the bracket pad “tracks” with a wire brush and spray with brake cleaner.

Step 4: Remove the caliper bracket (carrier)

• Remove the two caliper bracket bolts using a 17mm socket and breaker bar. (The bracket/carrier is the metal piece the pads ride in.)
• Set the bracket aside.

Step 5: Remove the rotor

• If the rotor is stuck, thread the M8 x 1.25 bolts (pair, 25-40mm long) into the rotor’s push-off holes evenly and tighten until the rotor pops free.
• If needed, tap the rotor hat with a rubber mallet to break rust loose.
• Clean the hub face with a wire brush and wipe clean with brake cleaner.

Step 6: Install the new rotor

• Spray both faces of the new rotor with brake cleaner to remove shipping oil and wipe dry.
• Install the rotor onto the hub.
• Hold it in place with one lug nut hand-threaded (use the 21mm socket to snug lightly).

Step 7: Reinstall the caliper bracket

• Reinstall the bracket and start the bolts by hand.
• Tighten with a 17mm socket and torque wrench: Torque to 123 Nm (91 ft-lbs).

Step 8: Install new hardware and pads

• Install new pad clips from the hardware kit into the bracket.
• Apply a thin film of brake lubricant where the pad ears touch the clips (do not get grease on pad/rotor friction surfaces).
• Install the new pads into the bracket.
• If pads don’t slide easily, re-clean the tracks.

Step 9: Compress the caliper piston

• Check the brake fluid reservoir level under the hood before compressing.
• Use a C-clamp (6" minimum) or disc brake piston compressor (specialty) to slowly press the piston fully back into the caliper.
• If fluid looks like it will overflow, remove a little with a clean suction tool into a catch pan (do not reuse contaminated fluid).

Step 10: Reinstall the caliper

• Set the caliper over the new pads.
• Install the two slide pin bolts using a 14mm socket.
• Tighten with a torque wrench: Torque to 34 Nm (25 ft-lbs).

Step 11: Repeat on the other front wheel

• Repeat Steps 2 through 10 on the other side.
• Always replace pads/rotors in pairs.

Step 12: Reinstall wheels and lower the Highlander

• Reinstall the wheels and hand-thread all lug nuts.
• Lower the Highlander off the jack stands using the floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a torque wrench: Torque to 140 Nm (103 ft-lbs).

✅ After Repair

• With the engine OFF, pump the brake pedal 10-15 times until it feels firm.
• Check brake fluid level and top off with DOT 3 brake fluid if needed.
• Do a slow test drive and confirm no pulling, grinding, or warning lights.
• Bed-in the pads: make 8-10 moderate stops from 35 mph to 5 mph, driving a bit between stops to cool.
