🔧 Focus - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the brake caliper and bracket, replace the rotor, then install new pads and reassemble. New rotors/pads restore stopping power and fix pulsation from warped rotors or worn pads.

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

Assumption: Factory front single-piston calipers; bolt heads may vary by build.

⚠️ Safety & Precautions

• ⚠️ Work on a flat surface; support the car on jack stands before going under or pulling hard on bolts.
• ⚠️ Do not let the brake caliper hang by the hose; use a caliper hanger (a hook/strap that supports it).
• ⚠️ Brake dust is harmful—use brake cleaner, not compressed air.
• ⚠️ After pushing the piston back, brake fluid can rise—watch the reservoir to prevent overflow.
• ⚠️ Pump the brake pedal before driving; the first push can go to the floor.

📋 Before You Begin

• Park on level ground, put the transmission in 1st gear, and set the parking brake.
• Chock the rear wheels with wheel chocks.
• Crack the front lug nuts loose 1/2 turn using a 19mm socket before lifting.
• Open the hood and locate the brake fluid reservoir; keep the cap sitting loosely on top (don’t remove it fully).
• Know your tools: a torque wrench tightens bolts to an exact spec so nothing comes loose or strips.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use a floor jack to lift the front at the approved jacking point.
• Place jack stands under the pinch welds/subframe points and lower onto them.
• Remove the front wheels using a 19mm socket.

Step 2: Remove the caliper (outer part)

• Turn the steering wheel to give yourself more room at the side you’re working on.
• Locate the two caliper slide/guide bolts on the back of the caliper.
• Remove the guide bolts using 7mm hex bit socket (common) or socket/wrench set if your bolts are standard hex heads. Use steady pressure—don’t round them.
• Lift the caliper off the bracket and support it with a caliper hanger hook (specialty).

Step 3: Remove the old pads and hardware

• Pull the pads out of the bracket by hand.
• Remove the pad abutment clips (the thin stainless clips the pad ears slide on) using a flathead screwdriver.
• Clean the bracket pad lands (where the clips sit) using a wire brush and brake parts cleaner spray.

Step 4: Remove the caliper bracket (carrier)

• Remove the two large bracket-to-knuckle bolts using a breaker bar (1/2") and the correct socket (commonly 15mm–18mm range).
• Set the bracket aside.
• When reinstalling later: Torque to 115 Nm (85 ft-lbs).

Step 5: Remove the rotor

• If equipped with a rotor retaining screw, remove it using a Torx T50 bit socket.
• If the rotor is stuck, spray the hub/rotor center with brake parts cleaner spray, then tap the rotor hat with a rubber mallet to break rust loose.
• Remove the rotor.

Step 6: Clean the hub surface (important for no pulsation)

• Clean the wheel hub face with a wire brush until it’s smooth and flat.
• Wipe clean with brake parts cleaner spray.
• A dirty hub can mimic “warped rotors.”

Step 7: Install the new rotor

• Clean the new rotor surfaces with brake parts cleaner spray to remove shipping oil.
• Place the rotor on the hub.
• If equipped, install the retaining screw using a Torx T50 bit socket and snug it (it mainly holds the rotor during assembly).

Step 8: Service the slide pins and reinstall the bracket

• Pull the caliper slide pins out of the bracket by hand.
• Clean and lightly grease the pins with brake lubricant (silicone/ceramic). (This grease is made for high heat and won’t swell rubber boots.)
• Reinstall the bracket and tighten the bracket bolts with a torque wrench: Torque to 115 Nm (85 ft-lbs).

Step 9: Install new clips and pads

• Install the new abutment clips onto the bracket by hand.
• Apply a very thin film of brake lubricant (silicone/ceramic) where the pad ears contact the clips (metal-to-metal only).
• Slide the new pads into the bracket.

Step 10: Compress the caliper piston

• Place an old pad against the piston face, then use a C-clamp (6") to slowly push the piston back into the caliper.
• Check the brake fluid reservoir while compressing; remove excess fluid if it nears the top.
• Go slow to protect the seals.

Step 11: Reinstall the caliper

• Set the caliper over the new pads.
• Install the caliper guide bolts using the 7mm hex bit socket (or the correct socket/wrench for your bolt type).
• Tighten with a torque wrench: Torque to 35 Nm (26 ft-lbs).

Step 12: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-tighten lug nuts using a 19mm socket.
• Lower the car off the jack stands using the floor jack.
• Torque lug nuts in a star pattern using a torque wrench: Torque to 135 Nm (100 ft-lbs).

✅ After Repair

• With the engine OFF, pump the brake pedal 10–15 times until it feels firm.
• Check brake fluid level and top off only if needed.
• Start the engine and hold the brake pedal; confirm it stays firm.
• Do a low-speed test drive and verify no grinding, pulling, or warning lights.
• Bed-in (break-in) the pads: make 6–10 medium stops from 35–45 mph with cool-down time between stops; avoid hard stops for the first 200 miles.
