🔧 Outback - Rear Brake Pads & Rotor Replacement

This job replaces your Outback’s rear brake pads and rotors, which restore stopping power and prevent vibration or grinding. Because your Outback uses an electronic parking brake (EPB) on the rear calipers, you must put the EPB into service/maintenance mode before compressing the pistons.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Support the vehicle on jack stands; never rely on a floor jack alone.
• ⚠️ Use wheel chocks on the front wheels before lifting the rear.
• ⚠️ EPB caution: do not push rear pistons in unless the EPB is in service/maintenance mode.
• ⚠️ Brake dust is harmful—use brake cleaner, not compressed air.
• ⚠️ Keep brake fluid off paint; it damages finishes quickly.
• ⚠️ Ignition should be OFF once the EPB is placed into service mode and before working near moving parts.

📋 Before You Begin

• Park on level ground, shift to Park, and release the parking brake.
• Chock both front wheels with wheel chocks.
• Turn ignition ON (engine OFF) and set the EPB into service mode using your scan tool with EPB service function (specialty). (Service mode retracts the EPB motors so the pistons can be pushed back safely.)
• After the scan tool confirms service mode, turn ignition OFF and keep the key away from the car.
• Loosen lug nuts before lifting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen rear lug nuts

• Use a 19mm socket and breaker bar to loosen (do not remove) the rear wheel lug nuts.

Step 2: Lift and secure the rear

• Lift the rear using a floor jack (rated 3-ton minimum) at the approved rear jack point.
• Set the vehicle on jack stands (rated 3-ton minimum) and gently shake-test stability.
• Remove both rear wheels using a 19mm socket.

Step 3: Remove the rear caliper (leave the hose attached)

• Turn the steering wheel straight and locate the rear caliper.
• Use a 14mm socket and 3/8" drive ratchet to remove the two caliper slide pin bolts.
• Lift the caliper off the bracket and hang it using a caliper hanger hook.
• Do not let the caliper hang by the brake hose.
• Torque on reassembly: Torque to 20 Nm (15 ft-lbs)

Step 4: Remove pads and hardware

• Pull the old pads out of the bracket by hand; use a flat blade screwdriver gently if stuck.
• Remove the pad abutment clips (hardware) from the bracket.
• Use brake cleaner spray to clean the bracket surfaces where the clips sit.

Step 5: Remove the caliper bracket

• Use a 17mm socket and breaker bar (or ratchet) to remove the two caliper bracket bolts.
• Remove the bracket and set it aside.
• Torque on reassembly: Torque to 65 Nm (48 ft-lbs)

Step 6: Remove the rotor

• If the rotor is stuck, thread M8 x 1.25 bolts (for rotor removal) into the rotor’s jacking holes and tighten evenly to press the rotor off the hub.
• Remove the rotor and clean the hub face with a wire brush.
• Spray the hub and surrounding area with brake cleaner spray and wipe clean.
• A clean hub helps prevent brake pulsation.

Step 7: Install the new rotor

• Clean the new rotor friction surfaces with brake cleaner spray to remove shipping oil.
• Install the rotor onto the hub.
• To hold it in place, thread on two lug nuts backwards by hand (temporary) and snug with a 19mm socket.

Step 8: Reinstall bracket and install new hardware

• Reinstall the caliper bracket and start the bolts by hand.
• Tighten bracket bolts using a 17mm socket and finish with a 1/2" drive torque wrench.
• Torque: Torque to 65 Nm (48 ft-lbs)
• Install new abutment clips from the rear brake pad hardware kit.
• Apply a thin film of high-temp silicone brake grease where the pad “ears” touch the clips.
• (Pad “ears” are the small metal tabs at the ends of the pad backing plate.)

Step 9: Compress the rear caliper piston (EPB must be in service mode)

• Verify the EPB is still in service/maintenance mode.
• Use a brake piston compressor tool (specialty) to slowly push the piston back into the caliper.
• Watch the brake fluid level in the reservoir; if it rises near MAX, stop and remove a small amount safely.
• Go slow to avoid damaging seals.

Step 10: Install new pads and reinstall caliper

• Install the new inner and outer pads into the bracket.
• Apply a very light coat of high-temp silicone brake grease to the pad backing plate contact points (where it touches the caliper).
• Lower the caliper over the new pads.
• Install the slide pin bolts using a 14mm socket and ratchet.
• Torque: Torque to 20 Nm (15 ft-lbs)

Step 11: Repeat on the other rear wheel

• Repeat Steps 3 through 10 on the opposite rear side.

Step 12: Reinstall wheels and torque lug nuts

• Reinstall both rear wheels and hand-thread lug nuts.
• Lower the vehicle to the ground using the floor jack.
• Torque lug nuts in a star pattern using a 1/2" drive torque wrench.
• Torque: Torque to 120 Nm (89 ft-lbs)

Step 13: Exit EPB service mode

• Turn ignition ON (engine OFF).
• Use the scan tool with EPB service function (specialty) to exit service/maintenance mode and re-initialize the EPB.

✅ After Repair

• With the engine OFF, pump the brake pedal 10-15 times until it feels firm (this seats the pistons against the pads).
• Check brake fluid level and top off only if needed.
• Start the engine and confirm the pedal feels normal.
• Test the EPB: apply and release it while stopped.
• Road test at low speed first; confirm no grinding, pulling, or warning lights.
• Brake bedding (pad break-in): make 6-10 smooth stops from 50 km/h to 15 km/h, with light driving between stops to cool.
