🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Enter Rear Brake Service Mode

• Plug the OBD-II scan tool with Toyota EPB service mode capability into the diagnostic port under the driver side dash.
• Select the Toyota parking brake or EPB service function.
• Choose the rear brake pad replacement or maintenance mode option.
• Wait until the scan tool confirms the rear electric parking brake is retracted.
• Listen for the rear motors.

Step 2: Loosen Rear Wheel Lug Nuts

• Use the 21mm lug nut socket and ratchet wrench to loosen each rear lug nut about half a turn.
• Do this while the tires are still touching the ground.

Step 3: Raise and Support the Rear

• Use the floor jack to lift the rear of your RAV4 at the rear center jacking point.
• Place jack stands under the approved rear side support points.
• Gently lower your RAV4 onto the jack stands.
• Shake the vehicle lightly by hand to confirm it is stable.

Step 4: Remove the Rear Wheels

• Use the 21mm lug nut socket and ratchet wrench to remove the loosened lug nuts.
• Remove both rear wheels and set them flat on the ground.

Step 5: Remove the Rear Caliper

• Use the 17mm open-end wrench to hold the caliper slide pin steady.
• Use the 14mm socket and ratchet wrench to remove the upper and lower rear caliper bolts.
• Lift the caliper off the bracket.
• Hang the caliper from the suspension using the bungee cord.
• Do not let the caliper hang by the brake hose.

Step 6: Remove the Old Brake Pads and Hardware

• Use the flathead screwdriver to gently pry the old pads out of the caliper bracket.
• Remove the old stainless pad clips from the bracket by hand or with the flathead screwdriver.
• Use the brake cleaner spray to clean the bracket.
• Use the small wire brush to clean the pad contact areas where the clips sit.

Step 7: Compress the Rear Caliper Piston

• Check that the electric parking brake is still in service mode before compressing the piston.
• Place the old inner pad against the caliper piston.
• Use the brake caliper piston compressor tool to slowly press the piston straight back into the caliper.
• A piston compressor pushes the caliper piston back to make room for the thicker new pads.
• Stop if the piston does not move smoothly.

Step 8: Install New Pad Hardware

• Snap the new rear brake pad hardware kit clips into the caliper bracket by hand.
• Apply a thin layer of brake lubricant to the pad contact points on the clips.
• Do not get lubricant on the pad friction material or rotor face.
• Less grease is better.

Step 9: Install the New Rear Brake Pads

• Slide the new rear brake pad set into the caliper bracket by hand.
• Make sure the pads move freely in the clips.
• If a pad is tight, remove it and clean the bracket again with the small wire brush.

Step 10: Reinstall the Rear Caliper

• Remove the bungee cord and lower the caliper over the new pads.
• Install the caliper bolts by hand first to avoid cross-threading.
• Use the 17mm open-end wrench to hold the slide pin steady.
• Use the 14mm socket and torque wrench to tighten the caliper bolts to Torque to 34 Nm (25 ft-lbs).

Step 11: Repeat on the Other Side

• Repeat Steps 5 through 10 on the opposite rear brake.
• Always replace rear brake pads in pairs.

Step 12: Reinstall the Rear Wheels

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

Step 13: Lower and Torque the Wheels

• Use the floor jack to raise your RAV4 slightly off the jack stands.
• Remove the jack stands.
• Lower the vehicle fully to the ground.
• Use the 21mm lug nut socket and torque wrench to tighten the rear lug nuts in a star pattern to Torque to 103 Nm (76 ft-lbs).

Step 14: Exit Rear Brake Service Mode

• Turn the ignition ON without starting the engine.
• Use the OBD-II scan tool with Toyota EPB service mode capability to exit parking brake service mode.
• Wait for the scan tool to confirm normal EPB operation.
• Apply and release the parking brake once using the parking brake switch.

Step 15: Seat the Brake Pads

• Use your foot to press the brake pedal slowly several times until it feels firm.
• This moves the caliper pistons back against the new pads.
• Do not drive until the pedal feels normal.
