🔧 Highlander - Rear Brake Pad Replacement

Replacing the rear brake pads requires lifting your Highlander, removing both rear calipers, compressing the caliper pistons, and installing new pads and hardware. The rear parking brake is a separate drum-style system, so no electronic service mode or scan tool is required.

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

⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and support your Highlander with jack stands.
• ⚠️ Release the parking brake before removing the rear calipers.
• ⚠️ Chock both front wheels because the parking brake must remain released.
• ⚠️ Never press the brake pedal while a caliper is removed.
• ⚠️ Do not allow a caliper to hang from its rubber brake hose.
• ⚠️ Brake dust can be harmful; use brake cleaner instead of compressed air.
• ⚠️ Battery disconnection is not required.

📋 Before You Begin

• 📍 Park your Highlander on level, solid ground and shift the transmission into Park.
• 📍 Release the foot-operated parking brake completely.
• 📍 Place wheel chocks securely in front of and behind both front tires.
• 📍 Open the hood and inspect the brake-fluid reservoir. If it is at the MAX line, use the 60mL fluid syringe to remove a small amount before compressing the pistons.
• 📍 Do not leave the reservoir open. Reinstall its cap loosely while you work.
• 📍 No infotainment menu, electronic parking-brake mode, or scan-tool command is required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Rear Wheel Nuts

• Use the 21mm deep socket and 1/2-inch breaker bar to loosen each rear wheel nut about one-quarter turn.
• Do not remove the wheel nuts while your Highlander is still on the ground.

Step 2: Raise and Support the Rear

• Use the 2-ton floor jack at the specified rear lifting point to raise your Highlander.
• Position the 2-ton jack stands beneath the reinforced rear side support points.
• Lower the vehicle carefully onto the stands, then gently shake the body to verify that it is stable.
• Keep the floor jack lightly touching the lifting point as a backup without carrying the vehicle’s weight.

Step 3: Remove Both Rear Wheels

• Use the 21mm deep socket and 1/2-inch breaker bar to remove the wheel nuts.
• Remove both rear wheels and place them flat away from the work area.
• Complete one brake side at a time.

Step 4: Inspect the Brake Assembly

• Put on the nitrile mechanic gloves and ANSI Z87.1 safety glasses.
• Use non-chlorinated brake cleaner and the nylon brake cleaning brush to remove loose dirt.
• Inspect the rotor for deep grooves, cracks, heavy rust, or blue heat marks. A damaged or undersized rotor must be replaced or professionally measured before continuing.
• Check the caliper and rubber brake hose for wetness. Wet brake fluid indicates a leak that must be repaired.

Step 5: Remove the Caliper

• Use the 14mm socket and 3/8-inch ratchet to remove the upper and lower caliper slide-pin bolts.
• A slide pin allows the caliper to move sideways as the pads wear.
• Lift the caliper away from the pads without pulling or twisting the brake hose.
• Support the caliper with the brake caliper hanger attached to a solid suspension point.

Step 6: Remove the Old Pads and Hardware

• Pull the inner and outer brake pads from the caliper bracket by hand.
• Use the small flat-blade screwdriver to lift the stainless-steel pad-support clips from the bracket.
• Note the location of the wear indicator on the original inner pad and install the new pad in the same orientation.
• Compare the old pads. Uneven wear can indicate a seized slide pin or sticking caliper.

Step 7: Clean and Lubricate the Contact Points

• Use brake cleaner and the nylon brake cleaning brush to clean the caliper-bracket areas beneath the clips.
• Install the new rear brake pad hardware by hand. Use the small flat-blade screwdriver only if needed to seat the clips gently.
• Apply a very thin film of high-temperature silicone brake lubricant where the pad tabs touch the hardware.
• Do not place lubricant on the rotor or pad friction surfaces.

Step 8: Check the Slide Pins

• Pull each slide pin from its rubber boot by hand, one at a time.
• Wipe the pin clean and inspect it for rust, scoring, or binding.
• Apply a thin coating of high-temperature silicone brake lubricant, then reinstall the pin into its original position.
• Confirm that each pin moves smoothly and that its rubber boot is fully seated.

Step 9: Compress the Caliper Piston

• Place an old brake pad against the piston face.
• Use the rear caliper piston compression tool to push the piston slowly and straight into the caliper bore.
• This piston presses straight inward; it does not need to be rotated.
• Watch the brake-fluid reservoir while compressing the piston. Use the 60mL fluid syringe if the fluid approaches the top.
• Stop if the piston will not move with moderate force. A seized caliper must be replaced.

Step 10: Install the New Pads

• Fit the new inner and outer pads into the caliper bracket by hand.
• Make sure the pad tabs sit fully inside the new support clips.
• Confirm that the friction material faces the rotor on both pads.
• Verify that the pads can slide slightly without binding.

Step 11: Reinstall the Caliper

• Remove the caliper hanger and lower the caliper over the new pads by hand.
• Do not force the caliper into place or twist the brake hose.
• Start both slide-pin bolts by hand to prevent crossed threads.
• Use the 14mm socket and 3/8-inch torque wrench to tighten both slide-pin bolts to 34 Nm (25 ft-lbs).

Step 12: Repeat on the Opposite Side

• Repeat Steps 4 through 11 on the other rear wheel using the same listed tools.
• Always replace rear brake pads as a complete axle set.

Step 13: Reinstall the Rear Wheels

• Install each wheel and start all wheel nuts by hand.
• Use the 21mm deep socket and 1/2-inch torque wrench to snug the nuts in a crisscross pattern while the vehicle remains supported.
• Do not apply final torque until the tires are on the ground.

Step 14: Lower and Torque the Wheels

• Use the 2-ton floor jack to raise your Highlander slightly, then remove both 2-ton jack stands.
• Lower the vehicle carefully until the tires rest fully on 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 15: Restore Brake Pedal Pressure

• Before starting the engine, press the brake pedal slowly several times until it becomes firm.
• Do not move your Highlander until the pedal feels firm and consistent.
• Inspect the brake-fluid reservoir and adjust the level to the MAX mark with fresh DOT 3 brake fluid if necessary.
• Secure the reservoir cap by hand.

✅ After Repair

• ✅ Start the engine while holding the brake pedal. Confirm that the pedal remains firm.
• ✅ Apply and release the parking brake to confirm normal operation.
• ✅ Check around both rear calipers for fluid leaks or loose components.
• ✅ Test the brakes at walking speed in a safe, traffic-free area before normal driving.
• ✅ Bed in the new pads with 8-10 moderate stops from approximately 50 km/h to 15 km/h, allowing brief cooling between stops.
• ✅ Avoid hard braking or holding the hot brakes at a complete stop during the first 300 km unless required for safety.
• ✅ Recheck the wheel-nut torque to 103 Nm (76 ft-lbs) after approximately 80-160 km.
