• ⚠️ Use jack stands before putting any part of your body near the brakes.
• ⚠️ Brake dust can be harmful. Do not blow it with compressed air.
• ⚠️ Brake fluid can damage paint. Wipe spills immediately with water.

📋 Before You Begin

• Park your Forester on level ground and shift the manual transmission into 1st gear.
• Set the parking brake and place wheel chocks behind the rear wheels.
• Loosen the front lug nuts slightly before lifting the vehicle.
• Open the hood and check the brake fluid reservoir. If it is full, remove a small amount with a clean fluid-safe syringe before compressing the caliper pistons.
• A caliper piston is the round part inside the brake caliper that pushes the pads against the rotor.
• A rotor is the round metal disc that the brake pads clamp onto to stop the vehicle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use a 19mm lug nut socket and 1/2-inch drive breaker bar to loosen each front lug nut about 1/2 turn.
• Do not remove the lug nuts yet.
• Loosen wheels before lifting.

Step 2: Lift and Support the Front

• Use a floor jack rated 2-ton minimum to lift the front of your Forester at the front center jacking point.
• Place jack stands rated 2-ton minimum under the proper front support points.
• Lower the vehicle gently onto the jack stands.
• Use wheel chocks at the rear wheels to prevent rolling.
• Give the vehicle a gentle shake to confirm it is stable.

Step 3: Remove the Front Wheels

• Use the 19mm lug nut socket and 1/2-inch drive ratchet to remove the front lug nuts.
• Remove both front wheels and set them flat under the vehicle as an extra safety backup.

Step 4: Remove the Caliper Slide Bolts

• Work on one side at a time so the other side can be used as a reference.
• Use a 14mm socket and 1/2-inch drive ratchet to remove the upper and lower front caliper slide bolts.
• A slide bolt holds the moving part of the caliper to the bracket and lets it move smoothly as the pads wear.
• If the slide pin spins, hold the pin steady with a suitable wrench while removing the bolt with the 14mm socket.

Step 5: Lift Off the Brake Caliper

• Use a flat-blade screwdriver medium to gently pry the caliper outward if it is tight.
• Lift the caliper off the rotor.
• Use a bungee cord 18-inch to hang the caliper from the strut spring.
• Do not stretch, twist, or hang the caliper by the rubber brake hose.

Step 6: Remove the Old Brake Pads

• Pull the old brake pads out of the caliper bracket by hand.
• Use a flat-blade screwdriver medium if a pad is stuck.
• Note the position of any wear indicator clips before removing them.
• A wear indicator is a small metal tab that makes noise when the pad is nearly worn out.

Step 7: Remove the Caliper Bracket

• Use a 17mm socket and 1/2-inch drive breaker bar to loosen the two caliper bracket bolts.
• Remove both bracket bolts with the 17mm socket and 1/2-inch drive ratchet.
• Remove the caliper bracket from the knuckle.

Step 8: Remove the Old Rotor

• Pull the rotor straight off the wheel hub by hand.
• If the rotor is stuck, tap around the rotor hat with a hammer if available, or carefully work it loose by hand.
• If your rotor has threaded removal holes, install matching bolts evenly and slowly to push the rotor free.
• Do not hit the wheel studs.

Step 9: Clean the Hub Face

• Use a wire brush to clean rust from the wheel hub face.
• Use brake cleaner aerosol and shop towels to wipe the hub clean.
• The hub face must be flat and clean so the new rotor does not wobble.
• Rust here can cause brake vibration.

Step 10: Install the New Rotor

• Use brake cleaner aerosol and shop towels to clean both friction surfaces of the new rotor.
• Slide the new rotor onto the wheel studs.
• Thread one lug nut on by hand to hold the rotor flat while you work.

Step 11: Service the Caliper Bracket

• Use a flat-blade screwdriver medium to remove the old pad hardware clips from the caliper bracket.
• Use a wire brush to clean the bracket where the clips sit.
• Install the new clips from the front brake hardware kit by hand.
• Apply a thin film of brake pad anti-squeal lubricant only where the pad ears contact the clips.
• Do not get lubricant on the rotor or pad friction material.

Step 12: Reinstall the Caliper Bracket

• Place the caliper bracket back over the rotor.
• Start both bracket bolts by hand to avoid cross-threading.
• Use the 17mm socket and torque wrench rated 20-150 ft-lbs to tighten the caliper bracket bolts.
• Torque to 80 Nm (59 ft-lbs)

Step 13: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use a C-clamp 6-inch or brake caliper piston compression tool to slowly push the piston fully back into the caliper.
• Go slowly and check the brake fluid reservoir often so it does not overflow.
• If fluid gets too high, remove a small amount using a clean fluid-safe syringe.

Step 14: Lubricate the Slide Pins

• Pull each slide pin out of the caliper bracket by hand.
• Wipe the pins clean with shop towels.
• Apply a light coat of brake caliper slide pin grease to each pin.
• Reinstall the pins by hand and make sure they move smoothly.
• Do not use regular grease. Brake grease is made to handle heat and rubber parts.

Step 15: Install the New Brake Pads

• Install the new inner and outer brake pads into the caliper bracket by hand.
• Make sure the pads slide freely in the new hardware clips.
• If the pad has a wear indicator, match its position to the old pad layout.
• Keep the pad friction surfaces clean.

Step 16: Reinstall the Caliper

• Remove the bungee cord 18-inch and lower the caliper over the new pads.
• Start the upper and lower slide bolts by hand.
• Use the 14mm socket and torque wrench rated 20-150 ft-lbs to tighten the slide bolts.
• Torque to 27 Nm (20 ft-lbs)

Step 17: Repeat on the Other Front Side

• Repeat Steps 4 through 16 on the opposite front brake.
• Use the same tools and keep each side clean.
• Always replace front pads and rotors in pairs.

Step 18: Reinstall the Wheels

• Remove the temporary lug nut holding each rotor.
• Install the wheels onto the hubs.
• Thread all lug nuts by hand first.
• Use the 19mm lug nut socket and 1/2-inch drive ratchet to snug the lug nuts in a star pattern.

Step 19: Lower the Vehicle and Torque Lug Nuts

• Use the floor jack rated 2-ton minimum to lift slightly off the jack stands.
• Remove the jack stands rated 2-ton minimum.
• Lower your Forester fully to the ground.
• Use the 19mm lug nut socket and torque wrench rated 20-150 ft-lbs to tighten lug nuts in a star pattern.
• Torque to 120 Nm (89 ft-lbs)

Step 20: Pump the Brake Pedal

• Before driving, press the brake pedal slowly several times until it feels firm.
• This moves the caliper pistons back into position against the new pads.
• Check the brake fluid level and top off only if needed with the correct brake fluid listed on the reservoir cap.
• Do not drive until the pedal feels firm.

✅ After Repair

• ✅ Start your Forester and press the brake pedal again. It should feel firm, not soft or sinking.
• ✅ Check around both front calipers for leaks.
• ✅ Test drive slowly in a safe area before normal driving.
• ✅ Bed in the new brakes: make 8-10 gentle stops from about 30 mph to 5 mph, allowing short cooling time between stops.
• ✅ Avoid hard braking for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after 25-50 miles using the 19mm lug nut socket and torque wrench rated 20-150 ft-lbs.
