🔧 RAV4 - Rear Brake Pad Replacement

This repair replaces the rear brake pads on your RAV4. The rear brakes use an electronic parking brake, so the parking brake system must be placed into service mode before removing the caliper.

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

⚠️ Safety & Precautions

• ⚠️ Your RAV4 has an electronic parking brake. Do not push the rear caliper piston back until the parking brake is in service mode.
• ⚠️ Work on a flat, solid surface and support the vehicle with jack stands. Never rely on a floor jack alone.
• ⚠️ Keep the ignition OFF while your hands are near the brake caliper after service mode is set.
• ⚠️ Brake dust can irritate your lungs. Use brake cleaner, not compressed air.
• ⚠️ Do not disconnect the 12V battery for this job unless instructed by a scan tool procedure; the electronic parking brake needs vehicle power for service mode.

📋 Before You Begin

• Park your RAV4 on level ground.
• Make sure the transmission is in Park.
• Chock the front wheels with wheel chocks.
• Release the parking brake before starting the service mode process.
• A scan tool is strongly recommended. An OBD scan tool plugs into the diagnostic port and can command the electronic parking brake motors to retract safely.
• If your scan tool has a menu, use: ABS/VSC/TRAC > Utility > ECB Utility > Rear Brake Pad Replacement / EPB Maintenance Mode.
• Do not open the driver door, press the parking brake switch, or turn the ignition ON/OFF randomly once the calipers are removed.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Enter Electronic Parking Brake Service Mode

• Use the OBD scan tool with electronic parking brake service mode and connect it to the diagnostic port under the driver-side dash.
• Turn the vehicle to ignition ON without starting it. Keep your foot off the brake and press the power button twice.
• Use the scan tool menu: ABS/VSC/TRAC > Utility > ECB Utility > Rear Brake Pad Replacement / EPB Maintenance Mode.
• Follow the scan tool prompts until the rear parking brake motors retract.
• Turn the ignition OFF when the scan tool says the vehicle is ready for pad replacement.
• Listen for both rear motors.

Step 2: Loosen the Rear Wheel Lug Nuts

• Use the 21mm lug nut socket and ratchet to loosen each rear lug nut about one turn.
• Do this while the tires are still touching the ground so the wheels do not spin.

Step 3: Raise and Support the Rear of the Vehicle

• Use the floor jack at the rear center jacking point to lift the rear of your RAV4.
• Place jack stands under the approved rear side support points.
• Lower the vehicle gently onto the jack stands.
• Keep the floor jack lightly touching the lift point as a backup.

Step 4: Remove the Rear Wheels

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

Step 5: Remove the Rear Caliper

• Use the 14mm socket to remove the lower rear caliper slide pin bolt.
• If the slide pin spins, hold it with the 17mm open-end wrench.
• Use the 14mm socket to remove the upper rear caliper slide pin bolt.
• Lift the caliper off the bracket carefully.
• Hang the caliper from the suspension using the brake caliper hanger hook.
• Do not let the caliper hang by the rubber brake hose.

Step 6: Remove the Old Brake Pads and Hardware

• Use your hands or a flat-blade screwdriver to slide the old brake pads out of the caliper bracket.
• Use the flat-blade screwdriver to remove the old stainless pad clips from the bracket.
• The pad clips are thin metal guides that help the pads slide smoothly.
• Compare the old pads to the new pads before installation.

Step 7: Clean the Caliper Bracket

• Use the brake cleaner spray to clean the caliper bracket where the pad clips sit.
• Use the small wire brush to remove rust and dirt from the bracket contact areas.
• Wipe the area clean with a shop towel.
• Clean clips prevent brake squeaks.

Step 8: Install New Brake Pad Hardware

• Use your hands to snap the new rear brake pad hardware clips into the caliper bracket.
• Apply a thin layer of brake lubricant to the areas of the clips where the pad ears touch.
• Do not put lubricant on the brake pad friction material or rotor surface.

Step 9: Compress the Rear Caliper Piston

• Use the disc brake pad spreader tool to slowly push the caliper piston straight back into the caliper bore.
• The caliper piston is the round metal part that presses the brake pad against the rotor.
• Move slowly and watch the brake fluid level in the reservoir under the hood.
• If the reservoir gets too full, stop and remove a small amount of fluid with a suitable fluid extractor.
• Do not twist the piston unless a Toyota-specific service instruction or scan tool tells you to.

Step 10: Install the New Rear Brake Pads

• Use your hands to install the new inner and outer rear brake pads into the caliper bracket.
• Make sure the pads slide freely in the new hardware clips.
• If the pads are tight, remove them and clean the bracket again with the small wire brush and brake cleaner spray.

Step 11: Reinstall the Rear Caliper

• Lower the caliper over the new pads by hand.
• Use the 14mm socket to install the upper and lower slide pin bolts.
• Hold the slide pin with the 17mm open-end wrench if it spins.
• Torque to 34 Nm (25 ft-lbs).

Step 12: Repeat on the Other Rear Side

• Repeat Steps 5 through 11 on the other rear brake assembly.
• Use the same tools and the same torque specification.
• Rear brake pads should always be replaced as an axle set, meaning both left and right sides together.

Step 13: Reinstall the Rear Wheels

• Put both rear wheels back onto the hubs by hand.
• Use the 21mm lug nut socket and ratchet to snug the lug nuts in a star pattern.
• Do not fully torque the lug nuts while the vehicle is in the air.

Step 14: Lower the Vehicle and Torque Lug Nuts

• Use the floor jack to raise the rear slightly and remove the jack stands.
• Lower your RAV4 until the tires touch the ground.
• Use the torque wrench with the 21mm lug nut socket.
• Torque to 103 Nm (76 ft-lbs) in a star pattern.

Step 15: Exit Electronic Parking Brake Service Mode

• Use the OBD scan tool with electronic parking brake service mode again.
• Turn ignition ON without starting the engine.
• Use the scan tool menu: ABS/VSC/TRAC > Utility > ECB Utility > Rear Brake Pad Replacement / EPB Maintenance Mode.
• Follow the prompts to exit service mode and initialize the rear parking brake.
• Apply and release the parking brake using the switch to confirm normal operation.

Step 16: Pump the Brake Pedal

• With the vehicle still in Park, press the brake pedal slowly 5-10 times.
• The pedal should become firm.
• Do not drive until the brake pedal feels firm.

✅ After Repair

• ✅ Check the brake fluid level and make sure it is between the MIN and MAX marks.
• ✅ Start your RAV4 and check for brake warning lights.
• ✅ Apply and release the electronic parking brake several times.
• ✅ Test drive slowly in a safe area and confirm normal braking.
• ✅ Bed in the new pads by making several gentle stops from 30-40 mph, allowing the brakes to cool between stops.
• ✅ Avoid hard braking for the first 100-200 miles unless it is an emergency.
