🔧 Avalon - Rear Brake Pad Replacement

You’ll remove the rear wheels, swing the rear calipers up, swap the old pads for new ones, then compress the caliper pistons so everything fits back together. This matters because worn pads reduce stopping power and can damage the rotors.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• 🛑 Work on level ground and use jack stands—never rely on a jack alone.
• 🔥 Brakes get hot; let everything cool before touching.
• 🧯 Don’t breathe brake dust—use brake cleaner, not compressed air.
• 🧱 Chock the front wheels before lifting the rear.
• 🔌 If your Avalon has an electronic parking brake (EPB) switch (not a foot pedal), tell me before you start—EPB systems may require a service mode.

📋 Before You Begin

• Park on a flat surface, shift to P, and turn the car off.
• Release the parking brake. (If you have a foot pedal parking brake, make sure it’s fully released.)
• Open the hood and locate the brake fluid reservoir. Don’t remove fluid yet—just be ready to watch the level when you compress the pistons.
• “Caliper piston” is the round part that pushes pads.
• A “bungee cord” supports the caliper—no hose strain.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen rear wheel lug nuts

• Use the 21mm socket and breaker bar to loosen the rear lug nuts about 1/2 turn (don’t remove them yet).

Step 2: Lift and support the rear of the car

• Place wheel chocks in front of both front tires.
• Use the floor jack (rated 3-ton minimum) to lift the rear at the approved center lift point.
• Set the car down onto jack stands (rated 3-ton minimum) placed at the rear support points.

Step 3: Remove the rear wheels

• Use the 21mm socket to remove the lug nuts and remove both rear wheels.

Step 4: Remove the caliper (swing it up/off the pads)

• Turn the steering wheel slightly if needed for access (rear access is usually straight-on).
• Use a 14mm socket and ratchet to remove the two rear caliper slide pin bolts.
• Carefully lift the caliper off the bracket.
• Support the caliper with a bungee cord. Do not let it hang by the rubber brake hose.

Step 5: Remove old pads and hardware

• Pull the old inner and outer pads out by hand. If stuck, gently pry with a flathead screwdriver.
• Remove the stainless pad clips (hardware) from the bracket.
• Spray the bracket areas with brake parts cleaner and scrub light rust with a wire brush.

Step 6: Check slide pins (important)

• Slide the two caliper pins in and out by hand (these are the pins the caliper “floats” on).
• If they feel sticky, pull each pin out, wipe it clean, apply a thin coat of brake caliper grease (silicone), and reinstall it.
• Sticky pins cause uneven pad wear.

Step 7: Install new hardware and pads

• Install the new stainless hardware clips onto the bracket by hand.
• Apply a thin film of brake caliper grease (silicone) where the pad “ears” touch the clips (metal-to-metal contact points only).
• Install the new inner and outer pads into the bracket.

Step 8: Compress the caliper piston

• Place the old inner brake pad against the piston face (acts like a buffer).
• Use the C-clamp (6" or larger) to slowly press the piston back into the caliper until it bottoms out.
• Watch the brake fluid level under the hood—if it gets near “MAX,” remove a small amount to prevent overflow.
• Go slow to avoid damaging seals.

Step 9: Reinstall the caliper and torque bolts

• Set the caliper back over the new pads.
• Install the slide pin bolts by hand first to avoid cross-threading.
• Use the 14mm socket and torque wrench: Torque to 34 Nm (25 ft-lbs).
• If you removed the caliper bracket (only needed for rotor replacement), use the 17mm socket and torque wrench: Torque to 90 Nm (66 ft-lbs).

Step 10: Reinstall wheels and torque lug nuts

• Put the wheels back on and hand-thread all lug nuts.
• Lower the car off the stands using the floor jack (rated 3-ton minimum).
• Use the 21mm socket and torque wrench to tighten lug nuts in a star pattern: Torque to 103 Nm (76 ft-lbs).

✅ After Repair

• With the car still off, press the brake pedal slowly 10–15 times until it feels firm. This seats the pistons against the new pads.
• Check brake fluid level and top off if needed (correct fluid for your Avalon is DOT 3).
• Start the car and do a low-speed test stop in a safe area.
• Pad break-in (bedding): do 6–10 moderate stops from ~30 mph to ~5 mph, with short cool-down driving between stops.
• Recheck for any abnormal noises and confirm the car rolls freely with the parking brake released.
