🔧 RAV4 - Rear Brake Pad Replacement

You’ll remove the rear calipers, retract the rear caliper pistons, then install new pads and reassemble everything with the correct torque. On your RAV4, the rear pistons typically need to be rotated while being pushed in because the parking brake mechanism is built into the caliper.

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

⚠️ Safety & Precautions

• ⚠️ Work on a level surface and support the RAV4 with jack stands, not just a jack.
• ⚠️ Release the parking brake before starting (rear brakes won’t come apart correctly if it’s set).
• ⚠️ Brake dust is harmful—use brake cleaner, don’t blow dust with compressed air.
• ⚠️ Do not let the caliper hang by the brake hose—support it with a hook/strap.

📋 Before You Begin

• 🅿️ Park on level ground, shift to P, and release the parking brake.
• 🧱 Place wheel chocks in front of the front tires.
• 🧴 Open the hood and locate the brake fluid reservoir; keep the cap loosely set on top (don’t remove it completely). Fluid may rise when pistons retract.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen rear wheel lug nuts

• Use a 21mm socket and ratchet to loosen (do not remove) the rear lug nuts about 1/2 turn.

Step 2: Lift and support the rear

• Use a floor jack to lift the rear at a proper jacking point.
• Set the RAV4 down onto jack stands and gently rock the vehicle to confirm it’s stable.
• Remove the wheels using the 21mm socket.

Step 3: Locate the rear caliper and remove the lower slide pin bolt

• Find the rear caliper (the clamp over the rotor) and the two slide pin bolts on the back side.
• Use a 14mm socket and ratchet to remove the lower slide pin bolt.
• Pivot the caliper upward like a hinge. Use a flathead screwdriver gently if needed to help it move (don’t pry on the rubber boot).

Step 4: Remove old pads and hardware

• Slide the pads out by hand.
• Remove the pad clips/hardware from the caliper bracket.
• Clean the bracket pad “rails” with brake cleaner spray and a wire brush.

Step 5: Retract the rear caliper piston (wind-back)

• Support the caliper with a bungee cord or mechanics wire so it’s not pulling on the hose.
• Install the rear disc brake piston wind-back tool kit (specialty) onto the piston face.
• Turn the tool to rotate the piston while pressing it inward until it bottoms out.
• A wind-back tool rotates and pushes the piston together.
• If brake fluid nears the top of the reservoir, remove a little with a clean rag (do not spill on paint).

Step 6: Install new pad hardware and grease contact points

• Install new hardware clips onto the bracket by hand.
• Apply a thin film of silicone brake grease where the pad “ears” touch the clips.
• Do not get grease on pad friction material or the rotor face.

Step 7: Install the new rear pads

• Slide the new pads into the bracket by hand.
• Make sure pads move freely in the clips (they should slide, not bind). If they bind, re-clean with brake cleaner spray and the wire brush.

Step 8: Reinstall the caliper and torque the slide pin bolt

• Pivot the caliper back down over the new pads.
• Reinstall the lower slide pin bolt using a 14mm socket and ratchet.
• Torque to 34 Nm (25 ft-lbs) using a torque wrench.

Step 9: Repeat on the other rear wheel

• Repeat Steps 3–8 on the other side. Use the same 14mm socket, wind-back tool kit, and torque wrench.
• Always replace rear pads as a pair.

Step 10: Reinstall wheels and torque lug nuts

• Reinstall both wheels and hand-thread the lug nuts.
• Lower the vehicle off the jack stands using the floor jack.
• Torque lug nuts in a star pattern with a torque wrench: Torque to 103 Nm (76 ft-lbs).

✅ After Repair

• 🦶 With the engine off, press the brake pedal slowly 10–15 times until it feels firm (this seats the pistons against the new pads).
• 🧪 Check the brake fluid level and top off only if needed (use the correct DOT rating shown on the reservoir cap).
• 🅿️ Re-apply and release the parking brake a few times to confirm normal feel.
• 🛣️ Test drive at low speed first; confirm no pulling, grinding, or warning lights.
• 🔥 Pad bedding: make 6–10 moderate stops from 30–40 mph, allowing short cool-down between stops.
