🔧 Rear Brake Pads - Replacement

The rear pads on your Sienna are replaced by removing the rear caliper, sliding out the old pads, and installing the new set with fresh hardware if included. Since the rear brakes also share the parking brake drum-in-hat design, make sure the parking brake is fully released before you start.

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

⚠️ Safety & Precautions

• Work on a level surface and chock the front wheels.
• Use jack stands; never rely on the jack alone.
• Let the brakes cool before touching them. Rotors can stay hot.
• Release the parking brake fully before removing the rear wheels.
• Do not press the brake pedal with a caliper removed.
• If the brake fluid reservoir is very full, watch for overflow when compressing the caliper piston.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear wheel

• Use a 19mm lug wrench to loosen and remove the rear wheel lug nuts.
• Set the wheel aside safely.

Step 2: Access the caliper

• Turn the steering wheel if needed for better access to the rear brake area.
• Inspect the brake hose and caliper for damage before moving anything.

Step 3: Remove the caliper bolts

• Use a 14mm socket and ratchet to remove the two caliper slide pin bolts.
• Lift the caliper off the bracket carefully.
• Hang the caliper with a bungee cord or mechanic's hook so the brake hose is not stretched.

Step 4: Remove the old pads and hardware

• Slide the old brake pads out of the bracket.
• Remove the pad clips and hardware using a flat-blade screwdriver if needed.
• Note how the pads sit so the new ones go in the same way.

Step 5: Inspect and clean the bracket

• Use a wire brush to clean rust from the pad contact points.
• Spray the bracket with brake cleaner and wipe it dry.
• Clean contact points help the pads slide smoothly.

Step 6: Compress the caliper piston

• Use a C-clamp or brake caliper compression tool (specialty) to slowly push the piston back into the caliper.
• Go slow and watch the brake fluid reservoir while compressing.
• If the piston is stiff, stop and make sure it is going in straight.

Step 7: Install new hardware and pads

• Install the new pad clips from the rear brake hardware kit.
• Apply a thin layer of brake lubricant to the pad ears and contact points only.
• Install the new rear brake pads into the bracket.

Step 8: Reinstall the caliper

• Slide the caliper back over the new pads.
• Use a 14mm socket to reinstall the caliper bolts.
• Torque to 34 Nm (25 ft-lbs).

Step 9: Reinstall the wheel

• Put the wheel back on and hand-tighten the lug nuts.
• Lower the vehicle slightly, then use a torque wrench and 19mm lug wrench to tighten the lug nuts in a star pattern.
• Torque to 103 Nm (76 ft-lbs).

Step 10: Repeat on the other side

• Replace the pads on the opposite rear wheel using the same steps.
• Replace pads in pairs for even braking.

✅ After Repair

• Listen for rubbing or clicking noises during the first drive.
