🔧 Highlander - Rear Brake Pad Replacement

This repair replaces the rear disc brake pads on your Highlander. The rear parking brake uses a separate drum-style mechanism inside the rotor, so you do not need an electronic parking brake service mode.

Difficulty Level: Beginner | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack by itself.
• ⚠️ Use jack stands before putting any part of your body near the wheel area.
• ⚠️ Rear brake dust can be harmful. Do not blow it off with compressed air.
• ⚠️ The brake pedal will feel soft after installation until you pump it several times.
• ⚠️ Brake cleaner is flammable. Keep it away from sparks, flames, and hot parts.
• ⚠️ Battery disconnect is not required for this rear brake pad replacement.

📋 Before You Begin

• Park your Highlander on level ground.
• Place the transmission in Park.
• Do not set the parking brake, because the rear brakes are being serviced.
• Place wheel chocks in front of both front tires.
• Open the hood and check the brake fluid reservoir. If it is completely full, remove a small amount with a clean suction tool before compressing the caliper piston.
• A caliper piston compressor tool slowly pushes the brake piston back into the caliper so the new thicker pads will fit.
• A caliper hanger hook supports the caliper so the brake hose is not stretched.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the rear lug nuts

• Use a 21mm lug nut socket and ratchet to loosen each rear wheel lug nut about half a turn.
• Do this while the tires are still touching the ground so the wheels do not spin.
• Loosen only; do not remove yet.

Step 2: Raise and support the rear of the Highlander

• Use a floor jack rated 2-ton minimum to lift the rear of your Highlander at a solid rear jacking point.
• Place jack stands rated 2-ton minimum under the rear support points.
• Lower the vehicle gently onto the jack stands.
• Lightly shake the vehicle by hand to confirm it is stable before removing the wheels.

Step 3: Remove the rear wheels

• Use the 21mm lug nut socket to remove the loosened lug nuts.
• Remove both rear wheels and place them flat under the vehicle as an extra safety backup.

Step 4: Remove the rear caliper lower bolt

• Look at the rear brake caliper. The caliper is the clamp-shaped part that holds the brake pads against the rotor.
• Use a 14mm socket and ratchet to remove the lower caliper slide pin bolt.
• If needed, use the 14mm socket to remove the upper caliper slide pin bolt too.
• Factory-style rear caliper slide pin bolts are tightened to Torque to 34 Nm (25 ft-lbs) during reassembly.

Step 5: Swing the caliper up or remove it

• Use your hands to swing the caliper upward off the brake pads.
• If the caliper will not swing freely, remove the upper bolt with the 14mm socket.
• Hang the caliper from the suspension using a brake caliper hanger hook.
• Do not let the caliper hang by the rubber brake hose.

Step 6: Remove the old rear brake pads

• Slide the old brake pads out of the caliper bracket by hand.
• If they are stuck, gently pry them out with a flat-head screwdriver.
• Note the position of any wear indicator tab before removing the pads. The wear indicator is the small metal tab that squeals when pads are worn.

Step 7: Remove and clean the pad hardware

• Remove the old stainless pad clips from the caliper bracket by hand or with a flat-head screwdriver.
• Use a wire brush to clean the bracket where the clips sit.
• Spray the area with brake cleaner spray and wipe it dry with shop towels.
• Clean brackets help prevent brake noise.

Step 8: Install the new brake pad hardware

• Install the new rear brake pad hardware clips by hand into the caliper bracket.
• Make sure each clip sits flat and fully snapped into place.
• Apply a thin layer of brake lubricant only where the pad ears touch the clips.
• Do not get lubricant on the pad friction material or rotor surface.

Step 9: Compress the rear caliper piston

• Place one old brake pad against the caliper piston.
• Use a brake caliper piston compressor tool to slowly push the piston fully back into the caliper.
• Watch the brake fluid reservoir while compressing. Stop if fluid gets close to overflowing.
• This rear caliper piston presses straight in; it does not need to be rotated.

Step 10: Install the new rear brake pads

• Slide the new rear brake pads into the caliper bracket by hand.
• Make sure the friction material faces the rotor.
• The pads should move smoothly in the clips without being loose.
• If a pad is tight, remove it and clean the bracket again with the wire brush.

Step 11: Reinstall the rear caliper

• Lower the caliper over the new pads by hand.
• Start the caliper slide pin bolts by hand first to avoid cross-threading.
• Use the 14mm socket to snug the bolts.
• Use the 3/8-inch torque wrench and 14mm socket to tighten the caliper slide pin bolts to Torque to 34 Nm (25 ft-lbs).

Step 12: Repeat on the other rear side

• Repeat Steps 4 through 11 on the other rear wheel.
• Always replace rear brake pads in pairs so braking stays even.

Step 13: Reinstall the rear wheels

• Place each wheel back on the hub by hand.
• Install the lug nuts by hand first.
• Use the 21mm lug nut socket to snug the lug nuts in a star pattern.

Step 14: Lower the Highlander and torque the lug nuts

• Use the floor jack rated 2-ton minimum to raise the rear slightly off the jack stands.
• Remove the jack stands rated 2-ton minimum.
• Lower the vehicle until the tires touch the ground.
• Use the 3/8-inch torque wrench and 21mm lug nut socket to tighten lug nuts in a star pattern to Torque to 103 Nm (76 ft-lbs).

Step 15: Pump the brake pedal

• Sit in the driver seat and press the brake pedal slowly several times.
• The pedal will travel low at first, then become firm.
• Do not drive until the brake pedal feels firm.

✅ After Repair

• Check the brake fluid reservoir and make sure the level is between MIN and MAX.
• Start your Highlander and press the brake pedal again to confirm it feels firm.
• Test drive slowly in a safe area first.
• Make several gentle stops from low speed before normal driving.
• For the first 100-200 miles, avoid hard braking unless needed for safety.
• After the test drive, recheck for abnormal noise, burning smell, or uneven braking.
