How to Replace Front Brake Pads & Rotors on a 2015-2019 Subaru Outback (DIY Guide)

🔧 Outback - Front Brake Pads & Rotor Replacement
You’ll remove the front wheels, take off the brake calipers and brackets, replace the rotors, then install new brake pads. This restores stopping power and fixes pulsation/shaking caused by warped rotors or worn pads.
Difficulty Level: Intermediate | Estimated Time: 2-4 hours
⚠️ Safety & Precautions
- 🛑 Work on level ground and use jack stands—never rely on a jack alone.
- Brake dust is harmful—use brake cleaner, not compressed air.
- Do not let the caliper hang by the brake hose—support it with a hook.
- Keep grease and brake fluid off pad/rotor friction surfaces.
- After compressing pistons, check the brake fluid level so it doesn’t overflow.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks

📋 Before You Begin
- Park your Outback on flat ground and set the parking brake.
- Place wheel chocks behind the rear wheels.
- Crack the front lug nuts loose 1/4 turn using a 19mm socket and breaker bar before lifting.
- Open the hood and locate the brake fluid reservoir; keep the cap loosely set on top (don’t remove it completely unless needed).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and support the front end
- Use a floor jack to lift the front at the approved front jacking point.
- Place jack stands under the front pinch welds or approved support points and lower onto them.
- Remove the front wheels using a 19mm socket.
Step 2: Remove the front brake caliper (do not stretch the hose)
- Turn the steering wheel to give yourself working room at the side you’re on.
- Remove the caliper slide pin bolts using a 14mm socket.
- Lift the caliper off the pads and support it with a caliper hanger hook. Never hang it by the hose.
Step 3: Remove old pads and inspect hardware
- Pull the pads out of the bracket by hand; use a flat-blade screwdriver gently if they’re stuck.
- Remove the pad clips/hardware from the bracket (usually they pop out by hand).
- Clean the bracket pad lands with a wire brush and brake cleaner spray.
Step 4: Remove the caliper bracket
- Remove the two caliper bracket bolts using a 17mm socket and breaker bar.
- Set the bracket aside.
- When reinstalling later: Torque to 80 N·m (59 ft-lbs).
Step 5: Remove the rotor
- If equipped with rotor retaining screws, remove them with a Phillips screwdriver.
- If the rotor is stuck, thread two M8 x 1.25 bolts into the rotor push-off holes evenly until the rotor pops loose.
- Tap around the rotor hat with a rubber mallet if needed, then remove the rotor.
Step 6: Prep the hub and install the new rotor
- Clean rust from the hub face with a wire brush, then spray with brake cleaner spray.
- Clean the new rotor faces with brake cleaner spray to remove packing oil.
- Install the new rotor. If you have retaining screws, reinstall them with a Phillips screwdriver (snug only).
- Hold the rotor in place by hand, or temporarily install 1-2 lug nuts by hand (no tools yet).
Step 7: Reinstall the caliper bracket
- Reinstall the bracket and start both bolts by hand.
- Tighten using a 17mm socket.
- Torque to 80 N·m (59 ft-lbs) using a torque wrench.
Step 8: Install new pad hardware and pads
- Install new pad clips/hardware into the bracket.
- Apply a thin film of brake caliper grease where the pad “ears” touch the clips. (This is the metal-to-metal sliding area.)
- Install the new inner and outer pads into the bracket by hand.
Step 9: Compress the caliper piston and reinstall the caliper
- Place an old brake pad against the piston face, then use a C-clamp brake piston compressor to slowly push the piston fully back in.
- Watch the brake fluid reservoir while compressing; remove a little fluid if it gets too high.
- Slide the caliper over the new pads.
- Install the slide pin bolts using a 14mm socket.
- Torque to 27 N·m (20 ft-lbs) using a torque wrench.
Step 10: Reinstall wheels and torque lug nuts
- Reinstall the wheels and hand-thread lug nuts.
- Lower the vehicle off the stands using the floor jack.
- Torque lug nuts in a star pattern using a 19mm socket and torque wrench: Torque to 120 N·m (89 ft-lbs).
✅ After Repair
- With the engine OFF, slowly pump the brake pedal 10–15 times until it feels firm. This seats pads to the rotor.
- Check brake fluid level and top off with DOT 3 or DOT 4 if needed.
- Start the engine and confirm the pedal feels normal.
- Do a cautious test drive and verify no grinding, pulling, or vibration.
- Pad bed-in (recommended): make 8–10 moderate stops from 40 to 10 mph, letting brakes cool a bit between stops; avoid hard panic stops for the first 200 miles.
